Introduction

These Terms and Conditions (hereinafter the “Terms”) govern the legal relationship between you as a player and the online casino and sports betting platform operated under the brand name Mostbet (hereinafter “Mostbet”, “we”, “us” or “our”). By accessing, browsing, registering an account or otherwise using any services offered on the Mostbet website or mobile applications (collectively, the “Platform”), you acknowledge that you have read, understood and agreed to be bound by these Terms. The Terms are designed to ensure a transparent, safe and responsible gaming environment, in line with applicable laws, industry standards and best practices for responsible gambling. These Terms apply to all products offered under the Mostbet brand, including, but not limited to, casino games, Slots, live dealer games, instant win games, and any promotional or loyalty programs. It is your responsibility to familiarize yourself with these Terms before using the Platform and to review them regularly in case of updates.

Mostbet reserves the right to amend, update or replace any part of these Terms at its sole discretion, to reflect changes in legal requirements, technical conditions or business operations. Any material changes will be made available on the Platform, and your continued use of the services after such changes have been posted constitutes your acceptance of the revised Terms. If at any time you do not agree with any part of these Terms, you must immediately stop using the Platform, close your account and, where applicable, contact customer support for guidance. The official language of these Terms is English as used for players accessing the Platform from Poland or using the English-language version with the code “en”. In case of any discrepancy between translated versions and the English version, the English version shall prevail to the extent permitted by applicable law.

These Terms are complemented by other important documents, including our Privacy Policy, KYC and AML Policies, Bonus Terms, and Responsible Gambling Policy. Together, these documents form the entire agreement between you and Mostbet with respect to the use of the Platform. You may access the main page of the service via Mostbet and the dedicated promotions page via Mostbet Bonuses, where additional specific rules may apply.

Acceptance of Terms

By creating an account, using the Platform, placing bets, playing casino games or participating in any promotion, you expressly confirm that you accept these Terms. Acceptance occurs at the moment you tick the relevant checkbox or press a button indicating agreement during the registration process or at any later stage when prompted by the Platform. You also agree that the electronic records of such acceptance maintained by Mostbet shall serve as conclusive evidence of your consent, unless you prove that they are incorrect or invalid under applicable law. If you do not agree with these Terms, or if any part of these Terms is not understandable to you, you must not proceed with registration or any use of the Platform and should seek clarification from customer support.

You acknowledge that some services on the Platform may be subject to additional specific rules or conditions, such as game-specific rules, tournament rules, bonus terms, or local jurisdictional requirements. In the event of a conflict between these Terms and any specific rules or provisions, the specific rules shall prevail for the relevant service, unless expressly stated otherwise. By accepting these Terms, you also confirm that you understand the inherent risks associated with gambling, including the risk of losing money, and that you undertake such activities at your own discretion and responsibility. You understand that Mostbet does not provide financial or investment advice and that all wagers are purely for entertainment purposes.

Acceptance of these Terms constitutes a binding legal agreement between you and Mostbet, enforceable in accordance with the governing law indicated below. If at any point after registration you cease to agree with these Terms, your only remedy is to discontinue use of the Platform and request account closure. Mostbet may, from time to time, require you to reconfirm your acceptance of these Terms, particularly following significant amendments, and your failure to do so may result in limitations on your access or suspension of your account.

Eligibility & Age Restriction (18+ only)

Use of the Mostbet Platform is strictly restricted to individuals who are at least eighteen (18) years of age, or older if the minimum legal age for participation in online gambling in their jurisdiction exceeds 18. By registering and using the Platform, you warrant that you meet the minimum legal age requirement and that you have full legal capacity to enter into binding contracts under the laws applicable to you. Mostbet takes underage gambling extremely seriously and implements a strict policy to prevent minors from accessing its services. Any attempt by a person under the age of 18 to open an account, deposit funds or place bets is a violation of these Terms and may constitute an offence in certain jurisdictions, including Poland. We reserve the right to request proof of age and identity at any time and to suspend or close accounts where satisfactory evidence is not provided.

Gambling can be particularly harmful to young people, whose decision-making and impulse control may still be developing. Exposure to gambling activities at an early age significantly increases the risk of developing problem gambling behaviours later in life. For this reason, we strongly encourage parents and guardians to take measures to protect minors, such as using parental control software, securing devices and payment methods, and monitoring online activities. If it comes to your attention that a minor has gained access to the Platform and created an account in your household or using your data, you must inform Mostbet immediately so that we can take appropriate action, including blocking the account and refunding any deposits made by or on behalf of the minor, where legally required.

By using the Platform, you also confirm that online gambling is legal in your jurisdiction and that you are not accessing the site from any prohibited country or region as set out in the Restricted Countries section below. You assume sole responsibility for determining whether your use of the Platform is compliant with local laws, and you agree that Mostbet shall not be liable if you use the services in breach of any legal restrictions. Mostbet reserves the right to conduct checks, including geo-location and IP checks, to verify that you are not located in a restricted jurisdiction and to suspend or close accounts found to be in violation.

Any winnings or bonuses obtained in breach of the age or jurisdictional restrictions set out in this section shall be deemed void, and any funds on such accounts may be forfeited, subject to any mandatory legal provisions that might apply. Mostbet may also report underage gambling incidents to relevant regulatory or child protection authorities if required by law.

Account Registration

To participate in real-money gaming and betting on the Mostbet Platform, you must complete the registration process and open a personal user account (the “Account”). You agree to provide accurate, complete and truthful information during registration, including your full name, date of birth, country of residence, address, phone number, valid email address and any other data requested by the Platform. You are responsible for ensuring that your registration details are kept up to date and for promptly notifying Mostbet of any changes, for example by updating your profile settings or contacting customer support. Each individual is allowed to hold only one Account with Mostbet, and opening multiple accounts, using aliases or registering on behalf of others is strictly prohibited. Accounts are for personal, non-commercial use only, and you may not share your login credentials or allow third parties to access or use your Account.

During registration, you will be required to choose a username and a secure password, or use other authentication methods provided by the Platform. You are responsible for maintaining the confidentiality of your login details and for all activities carried out through your Account. Mostbet strongly recommends using strong, unique passwords, enabling any additional security features offered, and avoiding use of public or shared devices to access the Platform. If you suspect that your login data has been compromised, or if you notice any unauthorized activity on your Account, you must change your password immediately and contact Mostbet customer support without delay. Mostbet is not liable for any losses arising from unauthorized access where you have failed to protect your credentials with reasonable care.

Mostbet reserves the right to refuse registration, suspend, or close any Account at its discretion, particularly if we have reasonable grounds to believe that the information provided is false or misleading, that the Account may be used for fraudulent, money-laundering or other illegal purposes, or that the user is in breach of these Terms or applicable law. You agree that we may request additional information or documentation at any stage, including during or after registration, for identity verification, KYC (Know Your Customer) procedures, or due to risk-based assessments. Failure to provide the requested information within the prescribed timeframe may lead to limitation, suspension or closure of your Account.

You also acknowledge that certain registration or verification procedures may be required as part of our compliance with anti-money-laundering (AML) and counter-terrorist financing (CTF) obligations. These procedures may include checks against databases, verification of identity documents, verification of payment methods and, in some cases, verification of the source of funds. By registering an Account, you consent to such checks and acknowledge that your data may be shared with third-party service providers for verification purposes, in line with our Privacy Policy.

Deposits & Withdrawals

To place real-money bets or participate in casino games, you must fund your Mostbet Account through one of the payment methods available on the Platform for your country and currency. All deposits must be made from payment instruments registered in your own name, and third-party payments are strictly prohibited. When you deposit funds, you confirm that the funds are derived from lawful sources and that you are not acting on behalf of another person or entity. Mostbet reserves the right to carry out additional checks on deposits, including enhanced due diligence on large or unusual transactions, in order to comply with AML and CTF regulations. We do not provide credit or allow gambling on margin; you may only wager amounts that are actually available in your Account balance.

Withdrawals are processed in accordance with these Terms, the Payment Rules and any applicable regulatory requirements. Before processing the first withdrawal, and subsequently whenever considered necessary, Mostbet may require successful completion of identity verification and KYC procedures. This may include submission of a government-issued identity document, proof of address (such as a utility bill or bank statement), and, where applicable, documents confirming ownership of the payment method used. Mostbet aims to process withdrawal requests within a reasonable time; however, processing times may vary depending on internal checks, payment provider procedures, weekends, public holidays and other external factors. You understand that delays may occur due to verification requirements, and you agree that Mostbet shall not be liable for such delays if they are the result of necessary compliance checks or third-party payment provider actions.

Mostbet generally aims to process withdrawals using the same payment method that was used for deposits, where technically and legally feasible. Where this is not possible, an alternative method may be offered, subject to additional verification requirements. We reserve the right to set minimum and maximum deposit and withdrawal limits, which may differ depending on the method, currency, user status or jurisdiction. Some payment providers or intermediary banks may impose their own fees or currency conversion charges, which are outside the control of Mostbet. It is your responsibility to familiarize yourself with all fees, timeframes and conditions associated with the payment methods you use.

In certain situations, withdrawals may be temporarily suspended, for example if suspicious or irregular activity is detected, if you have not met wagering requirements linked to bonuses, or if there is an active investigation regarding your Account. In such cases, Mostbet will inform you where legally permissible and may request additional documents or explanations. You must cooperate in good faith with any such requests. If you fail to do so or if the investigation reveals violations of these Terms, Mostbet may cancel withdrawals, forfeit bonuses or funds, and close the Account, subject to any legal rights you may have under applicable law.

Payment Methods Table

The following table presents typical payment methods that may be available on Mostbet. Availability, limits and conditions may vary by country, including for players in Poland, and are always subject to the information published within your Account cashier section.

This table is for indicative purposes only and does not create a binding obligation on Mostbet with respect to any specific method or timeframe. Always consult the cashier section within your Account for the latest and country-specific information. Mostbet may add, remove or modify payment methods at any time, without prior notice, where necessary for operational or regulatory reasons.

Bonuses & Promotions

Mostbet may, from time to time, offer bonuses, free spins, deposit matches, cashback, loyalty rewards and other promotional incentives (collectively “Bonuses”). Participation in any Bonus is voluntary, and you may be required to opt in during registration, deposit or via the promotions page. Each Bonus is governed by specific terms and conditions (“Bonus Terms”), which may include wagering requirements, minimum deposit amounts, maximum win limits, restricted games for wagering, expiry dates and other special conditions. By accepting a Bonus, you confirm that you have read and understood the corresponding Bonus Terms and that you agree to comply with them fully. Failure to meet the applicable Bonus Terms may result in the forfeiture of the Bonus and any associated winnings.

Bonuses are intended for recreational players and must be used in good faith. Any form of bonus abuse or misuse, including but not limited to, using multiple accounts, acting in collusion with other players, hedging bets, using low-risk wagering strategies to clear bonuses, or exploiting any loophole in the system, is strictly prohibited. Mostbet reserves the right to withhold, cancel, or retract any Bonus and associated winnings if we have reasonable grounds to suspect bonus abuse, fraudulent activity or breach of these Terms or specific Bonus Terms. In serious cases, we may also close the offending Account(s) and report suspected fraud or money laundering to relevant authorities.

Bonuses may be limited to one per user, household, IP address, device, payment method or any other parameter determined by Mostbet to prevent abuse. We also reserve the right to restrict eligibility for certain Bonuses based on your activity history, risk profile, jurisdiction, or any other reasonable criteria. Some Bonuses may not be available to players from certain countries or using certain currencies or payment methods. Always refer to the Bonus description and terms on the promotions page before claiming.

You acknowledge that Bonus funds are usually kept separate from your real-money balance and that wagering requirements typically apply to Bonus funds and, in some cases, to associated winnings. Only after fulfilment of the wagering requirements, as specified in the Bonus Terms, may Bonus funds and related winnings be converted into withdrawable real money. If you request a withdrawal while a Bonus with active wagering requirements is in place, Mostbet may cancel the Bonus and associated winnings, unless expressly stated otherwise in the relevant Bonus Terms. It is your responsibility to track your Bonus status, wagering progress and expiry dates through the dedicated sections in your Account.

Mostbet reserves the right to change or discontinue any Bonus or promotion at any time, including before you have claimed it, without prior notice, where permitted by law. However, any Bonus already credited to your Account will usually remain subject to the existing terms, unless continuation is impossible for legal or technical reasons, in which case Mostbet will inform you and may provide an alternative or cancel the Bonus in a fair manner.

Game Rules

All casino games, Slots, table games, live dealer games and other gaming products available on the Mostbet Platform are governed by their specific rules, paytables and game instructions, which form an integral part of these Terms. Before placing bets or initiating gameplay, you are responsible for reading and understanding the rules of the particular game. Many games provide an in-game help or information section that describes gameplay, winning combinations, payout ratios, special features, bonus rounds and any applicable limitations. If you are unsure about any aspect of a game, you should not proceed with real-money wagering until you have obtained sufficient information or tried the game in demo mode where available.

Bets placed on the Platform are considered final once they have been accepted and confirmed by our servers, and they cannot usually be cancelled or altered. In the event of any discrepancy between the outcome displayed on your device and the outcome recorded on the game server, the server record shall prevail. You acknowledge that interruptions, disconnections, latency or other technical issues may occasionally affect gameplay and that independent game logs and transaction records are used to determine the final outcome. In case of a malfunction of a game or Platform component, all affected bets and payouts may be deemed void, and any associated stakes may be returned to your Account, or the affected game round may be replayed, in accordance with the rules and applicable regulatory requirements.

Certain games may have specific limitations, such as minimum and maximum stakes, bet configuration restrictions, or exclusion from Bonus wagering. Some games may require your explicit consent to participate in side bets, jackpots or features with higher volatility or additional risk. Progressive jackpots and networked jackpot games may be subject to third-party rules and technical conditions, and their availability may depend on your jurisdiction, currency, and whether you are playing from Poland or another permitted country. In the case of progressive jackpots, the jackpot value at the time of winning is the one stored on the game server, which may differ slightly from the value visually displayed due to delay in data transmission.

You agree not to use any technique, tool or system that gives you an unfair advantage over the games, including but not limited to software aids, bots, scripts, automated betting tools, prediction algorithms or any form of unauthorized external assistance. Card counting or other advantage play strategies may also be restricted or monitored in certain live dealer games, in accordance with game provider policies. Mostbet reserves the right to void bets, withhold winnings and take any other necessary measures if we have reasonable grounds to believe that you have violated game rules or attempted to gain an unfair advantage.

Fair Play & RNG

Mostbet is committed to providing a fair and transparent gaming environment. The outcomes of virtual casino games and Slots available on the Platform are determined by certified Random Number Generator (RNG) technology, which ensures that each game result is random and independent from previous results. The RNG is periodically tested and audited by recognized independent testing laboratories to verify that it operates in accordance with industry standards and regulatory requirements. These tests cover the randomness of outcomes, return-to-player (RTP) percentages and the correct implementation of game rules. By using the Platform, you acknowledge that you understand the role of the RNG and agree that game outcomes generated by it are final and binding.

Mostbet collaborates with reputable game providers who are themselves subject to licensing and certification requirements in various jurisdictions. These providers are responsible for the correct functioning of their games, including RNG and payout mechanics. Any reported or detected malfunction is investigated on a case-by-case basis in cooperation with the relevant provider. If a malfunction is confirmed, Mostbet will take appropriate remedial action, which may include voiding affected bets, refunding stakes, or correcting account balances. You understand that game providers may temporarily remove or suspend certain games if technical or regulatory issues arise.

We strictly prohibit any attempt to manipulate game outcomes, exploit bugs or glitches in games or software, or otherwise interfere with the integrity of the gaming environment. This includes, but is not limited to, intentional disconnection to influence game outcomes, exploiting obvious errors, or using unauthorized tools or data to gain insights into the RNG. If Mostbet has reasonable grounds to believe that such behaviour has occurred, we may suspend your Account, withhold winnings and report the incident to the relevant authorities, subject to applicable law. You may also be permanently banned from accessing the Platform.

Fair play also implies that you should behave in a respectful and honest manner towards other players and live dealers in multi-player or live dealer environments. Any abusive, offensive or disruptive behaviour, as well as any collusion or coordinated betting strategy, can undermine the fairness of the games and may lead to sanctions, including account suspension or closure. Mostbet may use monitoring tools, data analysis and behavioural analytics to detect patterns indicative of unfair play or collusion, always in accordance with privacy and data protection laws.

By using the Platform, you accept that no gambling system, betting strategy or method can guarantee consistent winnings or circumvent the RNG. Any statement, advertisement or tip from third parties suggesting guaranteed wins should be treated with caution and is not endorsed by Mostbet. You should only gamble with funds you can afford to lose and consider the outcomes purely as a matter of chance.

Responsible Gambling

Mostbet is strongly committed to promoting responsible gambling and providing a safe environment for adults who choose to participate in online gaming. We recognize that, while gambling can be an enjoyable form of entertainment for many, it also carries a risk of financial harm and can lead to problematic or addictive behaviour in some individuals. Our responsible gambling framework is based on prevention, early identification of risk, and effective intervention tools. We encourage all players in Poland and other permitted jurisdictions to gamble sensibly, to be aware of the risks, and to make informed decisions about their participation.

Young people and vulnerable individuals are particularly at risk of harm from gambling. Mostbet therefore implements strict age verification procedures and actively discourages underage users from attempting to access the Platform. We also provide extensive information and tools to help you control your gambling activity, including deposit limits, session reminders, time limits, cooling-off periods and self-exclusion options. These tools are designed to give you control over your behaviour and to provide structured ways to limit or stop your gambling when necessary. We urge you to use these features proactively, especially if you notice any signs of loss of control, such as chasing losses, gambling with money you cannot afford to lose, or neglecting work, family or social responsibilities.

Mostbet also cooperates with recognized support and counselling organizations specializing in gambling-related problems. We provide links and contact details to such organizations in the Support Resources section below so that you can seek confidential, professional help whenever needed. Our customer support team is trained to provide information on responsible gambling, including how to use the available tools and where to find external support. However, they cannot provide legal advice or professional therapy; their role is to guide you towards appropriate resources.

You should regularly review your gambling activity, including transaction history, time spent on the Platform and emotional responses to wins and losses. If you feel that gambling is no longer just entertainment but is causing you stress, anxiety, depression or financial difficulties, you should consider reducing or stopping your activity and using the available limitation tools. In severe cases, you should seek immediate professional help. Remember that you are always responsible for your own decisions and behaviour, but Mostbet is committed to assisting you in maintaining a healthy and controlled relationship with gambling.

Tools & Features (table)

Mostbet offers a range of responsible gambling tools and features that can be activated by players directly in their Account settings or by contacting customer support. The following table summarizes the main tools available:

These tools are provided for your benefit and should be used honestly and deliberately. Mostbet may, at its discretion, impose certain limits or restrictions on your Account if there are indications of problem gambling or if required by law or regulatory guidance. Where feasible, we will inform you about such measures and the reasons for them.

Support Resources

If you suspect that you may have a gambling problem or if your gambling is negatively affecting your life, Mostbet strongly encourages you to seek help from independent professional organizations. While we do not promote specific institutions in a commercial manner, we provide generic references to types of reputable support services that typically operate internationally or locally. These may include gambling addiction helplines, counselling services, online support forums and self-help groups. Many of these organizations offer anonymous and confidential assistance, often free of charge, and can provide both immediate support and long-term therapy options.

Common types of support organizations include specialized gambling counselling services that provide assessments, one-to-one counselling sessions and family therapy. There are also international online therapy services focusing on gambling-related harm, which offer live chat, email or video sessions and multilingual support. Peer support groups, often inspired by the principles of anonymous recovery programs, can provide a community of individuals sharing similar experiences and coping strategies. In many countries, including in Europe, national or regional helplines operate 24/7 and can direct you to local professionals.

Within the Mostbet Platform, we maintain a dedicated Responsible Gambling section providing educational materials, tips for safe play and links to support organizations operating internationally, such as specialized gambling therapy networks and helplines. You may also ask our customer support team for practical guidance on how to access support in your region, including Poland. They can provide you with general information and links but will not be able to diagnose or treat any condition. Ultimately, you remain responsible for deciding whether to seek help and for following any treatment or counselling plans.

We encourage you to talk openly with trusted family members or friends about your gambling if you feel comfortable doing so, as social support can be a crucial factor in recovery. If you are a relative or friend of someone who might be experiencing gambling harm, you may also find resources aimed at affected others, offering advice on how to provide support and protect yourself from financial or emotional harm. Remember that problem gambling is a recognized condition that can be treated, and seeking help is a sign of strength, not weakness.

Prohibited Activities

When using the Mostbet Platform, you agree not to engage in any activities that are illegal, fraudulent, abusive, or otherwise contrary to these Terms, applicable law or fair play principles. Prohibited activities include, but are not limited to, money laundering, terrorist financing, identity theft, payment fraud, chargebacks, use of stolen or unauthorized payment methods, and any other offence under criminal or regulatory law. You are also prohibited from registering multiple accounts, sharing your Account with others, or using another person’s Account or payment details. Any attempt to gain unauthorized access to our systems, alter or tamper with software, or interfere with the security and integrity of the Platform is strictly forbidden.

Using automated tools, bots, scripts or mechanical devices to place bets, play games or otherwise interact with the Platform is not allowed. So-called “bonus hunting” strategies, where Bonuses are systematically exploited without genuine recreational play, as well as the use of arbitrage or hedging tactics solely to profit from promotional offers, are considered abuse and may result in sanctions. Collusion with other players, including in live dealer games or multi-player environments, to influence the outcome of bets or to share confidential information, is also prohibited. Harassment, abusive language, threats, hate speech, or any form of offensive behaviour towards other players, live dealers or Mostbet staff is unacceptable and may lead to immediate disciplinary measures.

The use of VPNs, proxies or any other technology to mask or alter your true location, IP address or device identity in order to bypass geographical restrictions or legal requirements is strictly prohibited. If we detect or reasonably suspect that you are using such tools, your Account may be immediately suspended, and any pending withdrawals may be subject to review. Similarly, you must not sell, transfer or acquire Accounts, balances or access rights from other players, as Accounts are personal and non-transferable. Any attempt to circumvent self-exclusion, time-out or other responsible gambling tools by opening new accounts or using false information is a severe breach of these Terms.

If Mostbet reasonably believes that you have engaged in any prohibited activity, we may, at our discretion, suspend or close your Account, cancel bets, confiscate Bonuses and winnings, and withhold funds to the extent permitted by law while an investigation is conducted. We may also report suspected criminal activities to the appropriate authorities, banks or payment providers and cooperate fully with any subsequent investigation. You may be held liable for any damage or loss incurred by Mostbet as a result of your prohibited activities, including legal fees and costs of investigations.

Restricted Countries (table)

Due to legal, regulatory and commercial reasons, Mostbet may not be available to residents of or persons located in certain countries or territories. The following table lists examples of restricted countries for illustrative purposes only; the definitive list is always that published on the Platform and may change over time.

Players currently located in or permanently residing in restricted countries are not permitted to open an Account or use the Platform. You are solely responsible for ensuring that your use of Mostbet complies with local laws and for not accessing the services from any restricted location. If Mostbet determines that you are breaching these restrictions, we may close your Account, void bets and confiscate funds in accordance with applicable law and regulatory obligations.

Privacy & Data Protection

Mostbet is committed to protecting your personal data and handling it in a lawful, fair and transparent manner. We collect and process personal data strictly in accordance with applicable data protection laws, including where relevant the General Data Protection Regulation (GDPR) as applicable in the European Union and Poland. Our Privacy Policy explains in detail what data we collect, the purposes for which it is used, the legal bases for processing, and your rights as a data subject. By using the Platform and accepting these Terms, you also acknowledge that you have read and understood the Privacy Policy and consent to the collection and processing of your data as described therein, where such consent is required.

The categories of data we process may include identification data (such as name, date of birth and ID document details), contact data (email address, phone number, residential address), account and transaction data (deposits, withdrawals, bets, winnings), technical data (IP address, device identifiers, browser type, cookies) and other information necessary for KYC, AML, fraud prevention and responsible gambling purposes. We may also collect documentation you submit for verification, as well as communication records from interactions with customer support. This data is used, among other purposes, to provide and maintain the services, process transactions, verify your identity, prevent fraud and money laundering, comply with legal obligations, and improve the Platform.

Personal data may be shared with third-party service providers who assist us in delivering our services, such as payment processors, identity verification services, risk and AML monitoring tools, IT and hosting providers, and game providers. These third parties act under contractual obligations to process data only as instructed by Mostbet and to maintain appropriate security measures. We may also disclose data to competent authorities, regulators or law enforcement when legally required or when necessary to protect our rights, the rights of other players or the integrity of the Platform. In some cases, personal data may be transferred outside the European Economic Area, in which case we implement appropriate safeguards, such as standard contractual clauses or equivalent mechanisms.

Mostbet retains your personal data for as long as necessary to fulfil the purposes for which it was collected, and to comply with legal and regulatory retention obligations, for example in relation to AML and accounting rules. Retention periods may therefore extend beyond the closure of your Account. At the end of the retention period, data is deleted or anonymized in a secure manner. You have various rights in relation to your personal data, including the right of access, rectification, erasure (where legally possible), restriction of processing, data portability and the right to object to certain processing activities. You also have the right to lodge a complaint with a competent data protection authority if you believe that your rights have been infringed.

We use cookies and similar technologies to operate the Platform, personalize content, analyze traffic and improve user experience. You can manage your cookie preferences via your browser settings or through tools provided on the Platform, although some cookies are essential for the proper functioning of the site. For detailed information on cookies, categories and purposes, please refer to our Cookie Policy, which forms part of the Privacy framework.

Account Suspension & Termination

Mostbet reserves the right to suspend, limit or terminate your Account at any time and for any of the reasons stated in these Terms, particularly in cases of suspected breach, fraud, prohibited activities, legal non-compliance or security concerns. Suspension may be temporary or indefinite and can result in the blocking of access to some or all services, including deposits, wagering or withdrawals, pending investigation. Where legally possible and appropriate, we will inform you of the suspension and the reasons behind it, and may request additional information or documents to resolve the matter. During a suspension, you remain bound by these Terms and are expected to cooperate fully with any ongoing investigation.

You may request the closure of your Account at any time by contacting customer support, subject to settlement of outstanding balances and obligations. Before closure, you should withdraw any remaining funds in accordance with the applicable procedures, unless the funds are subject to a hold under AML, fraud or legal investigation. Voluntary closure does not necessarily equate to self-exclusion; if you wish to self-exclude for responsible gambling reasons, you should clearly request self-exclusion and specify the desired duration, in accordance with the Responsible Gambling section above. Once your Account is permanently closed, whether by you or by Mostbet, you will no longer be able to log in or use the services, except for limited purposes such as accessing transaction records where legally required.

If your Account is terminated by Mostbet due to serious breach of these Terms, including but not limited to fraud, money laundering, underage gambling, abuse of Bonuses or prohibited activities, Mostbet may, to the extent permitted by law, confiscate any remaining funds, cancel pending bets and void winnings obtained through such breach. We may also report your details to relevant authorities, regulators, or industry bodies and may restrict your ability to open new accounts in the future. In less severe cases, Mostbet may decide to close your current Account while returning any undisputed funds and allowing you to withdraw them, subject to verification.

Accounts that are inactive for an extended period (e.g. 12 consecutive months without login) may be classified as dormant. Mostbet may take reasonable steps to contact you using your registered contact details before applying any dormant account policy, which may include administrative fees, account closure or transfer of unclaimed funds in accordance with applicable law. Any such policy will be clearly described on the Platform and implemented in a transparent manner.

Limitation of Liability

To the maximum extent permitted by applicable law, Mostbet provides the Platform and all services on an “as is” and “as available” basis, without any warranties or representations, express or implied, regarding the uninterrupted, error-free or fully secure operation of the Platform or the accuracy, completeness or reliability of any content. While we take reasonable measures to ensure a high standard of service, technical problems, interruptions, maintenance work or external factors beyond our control may occasionally affect availability. You acknowledge that you use the Platform at your own risk and that you are responsible for ensuring that your hardware, software and internet connection are compatible with the Platform’s technical requirements.

Mostbet shall not be liable for any indirect, incidental, consequential, special or punitive damages, including loss of profits, loss of data, loss of business, or loss of goodwill, arising from or in connection with your use of the Platform, even if we have been advised of the possibility of such damages. Our liability for direct damages, where such limitation is allowed by law, shall be limited to the amount of your net losses on the Platform over the thirty (30) days preceding the event giving rise to the claim, or another reasonable amount defined by applicable law. Nothing in these Terms shall exclude or limit liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under mandatory law.

Mostbet is not responsible for failures or delays caused by force majeure events, including but not limited to natural disasters, war, civil unrest, strikes, interruptions in telecommunication or internet services, power outages, government actions, pandemics or other circumstances beyond our reasonable control. In such cases, we may suspend or modify services until normal operations can be resumed. We are also not responsible for technical or communication failures on your side, including device malfunction, low bandwidth, internet interruptions or software incompatibilities, which may affect your ability to access or use the Platform.

You are solely responsible for any tax obligations or reporting duties related to your gambling activities and winnings under the laws of your jurisdiction, including Poland where applicable. Mostbet does not provide tax advice and is not responsible for your failure to comply with any relevant tax legislation. You agree to indemnify and hold harmless Mostbet, its affiliates, employees and partners from and against any claims, liabilities, damages, losses, costs and expenses arising from your breach of these Terms, illegal activities, or misuse of the Platform.

Complaints & Dispute Resolution

Mostbet strives to provide a high-quality, fair and transparent service. If you are dissatisfied with any aspect of the Platform, including game outcomes, transaction handling or customer service, you have the right to submit a complaint. Complaints should be submitted as soon as reasonably possible after the issue arises, and in any case within reasonable time limits which may be prescribed on the Platform. You are encouraged to provide clear and detailed information, including your username, relevant dates and times, game titles, transaction IDs, screenshots or other evidence to support your complaint. Complaints should be submitted through the official channels indicated on the Platform, typically via email or a dedicated support form.

Upon receipt of your complaint, Mostbet will acknowledge it within a reasonable period and will initiate an internal investigation. We aim to resolve complaints in a fair, objective and timely manner, taking into account all relevant facts, game logs, transaction records and communication history. The time required to provide a final response may vary depending on the complexity of the case, but we will endeavour to keep you informed of progress. If additional information is required from you, we will contact you using your registered email address or other contact details.

If you are not satisfied with the outcome of the internal complaint process, you may have the option to refer the dispute to an independent dispute resolution body, mediator or relevant regulatory authority, where such mechanism exists and is applicable to your case. Information on any such external channels will be provided on the Platform or on request. You may also seek legal advice and pursue your claims in a competent court, in accordance with the Governing Law section below. However, we encourage you to exhaust internal and any available alternative dispute resolution mechanisms before initiating formal legal proceedings, as this may lead to quicker and less costly resolutions for both parties.

All complaints and disputes shall be handled in accordance with applicable data protection and confidentiality obligations. You agree to communicate with Mostbet’s support team and complaint handlers in a respectful and constructive manner, refraining from abusive language or threats. Mostbet reserves the right to decline to respond to complaints that are clearly frivolous, malicious or abusive, or that repeat issues already addressed in a final decision, unless new and relevant information is presented.

Governing Law

These Terms and any disputes, claims or proceedings arising out of or relating to them, the use of the Platform or the services provided by Mostbet shall be governed by and interpreted in accordance with the laws of the jurisdiction under which the operating entity of Mostbet is incorporated, unless mandatory provisions of consumer protection law in your country of residence (including Poland, where applicable) provide otherwise. The choice of governing law does not affect your right, as a consumer, to rely on mandatory provisions of the law of your country of residence that cannot be derogated from by agreement.

Any legal actions or proceedings arising under or in connection with these Terms shall be brought before the competent courts of the jurisdiction referred to in the preceding paragraph, unless otherwise required by applicable consumer protection rules. Mostbet and you agree to submit to the personal jurisdiction of such courts for the resolution of such disputes, without prejudice to any alternative dispute resolution mechanisms that may be used beforehand. If any provision of these Terms is found to be invalid or unenforceable by a competent court, such provision shall be modified or severed to the minimum extent necessary, and the remaining provisions shall continue in full force and effect.

Nothing in this Governing Law clause shall limit Mostbet’s right to bring proceedings against you in any other court of competent jurisdiction, particularly in cases involving fraud, infringement of intellectual property rights, or unlawful use of the Platform. Similarly, if you are a consumer and mandatory law provides the right to bring an action in the courts of your place of residence, such rights remain unaffected.

Final Provisions

These Terms, together with the Privacy Policy, Cookie Policy, Responsible Gambling Policy, Bonus Terms, game rules and any other documents explicitly incorporated by reference, constitute the entire agreement between you and Mostbet regarding the use of the Platform. They supersede any prior agreements, understandings or communications, whether oral or written, relating to the subject matter herein. You may not assign, transfer or delegate any of your rights or obligations under these Terms to any third party without the prior written consent of Mostbet. We may assign or transfer our rights and obligations under these Terms to another entity within our corporate group or to a third party in connection with a business transfer, merger or reorganization, provided that such transfer does not reduce your rights as a consumer under applicable law.

Mostbet reserves the right to modify, amend or update these Terms at any time, for example to reflect changes in legal requirements, technical standards, or business operations. Where the changes are material, we will endeavour to inform you in advance through the Platform or by email, and the updated Terms will specify their effective date. Your continued use of the Platform after the effective date of the updated Terms constitutes your acceptance of the changes. If you do not agree with the amended Terms, you should stop using the Platform and request the closure of your Account.

No failure or delay by Mostbet in exercising any right, power or remedy under these Terms shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. If any provision of these Terms is held to be invalid or unenforceable by a competent authority, the remaining provisions shall continue to be valid and enforceable, and the invalid or unenforceable provision shall be replaced by a valid and enforceable provision that comes closest to the original economic and legal intent.

If you have any questions, concerns or requests relating to these Terms, the Platform, responsible gambling tools or data protection, you should contact Mostbet customer support through the official channels indicated on the website. We encourage you to keep a copy of these Terms for your records and to consult them regularly at Mostbet for any updates or clarifications.

By registering an Account and using the services of Mostbet, you confirm that you have read these Terms and Conditions in full, that you understand them, and that you agree to be bound by them at all times while using the Platform.
