Introduction

These Terms and Conditions (“Terms”, “T&Cs”) govern the use of the online casino and betting services offered under the brand name Mostbet (“Mostbet”, “we”, “us”, “our”). By creating an account, accessing, or using any part of the website, mobile applications, or related platforms operated under the Mostbet brand, you acknowledge that you have read, understood, and agreed to be bound by these Terms. The Terms apply to all casino games, Slots, live dealer games, and any other interactive services or products made available by Mostbet. They are designed to ensure transparent operation, legal compliance, and a safe environment, with a strong focus on responsible gambling. If you do not agree with any part of these Terms, you must immediately stop using the services and refrain from registering an account. These Terms form a binding legal agreement between you and Mostbet, subject to the applicable governing law described below.

In addition to these Terms, you are bound by our Privacy and Data Protection rules, responsible gambling policies, payment rules, and any game-specific rules published on the site. You should review these documents regularly, as they may be updated from time to time to reflect changes in regulations or in our services. By continuing to use Mostbet after any update, you confirm your acceptance of the revised Terms and any supplementary policies. For the avoidance of doubt, in the event of conflict between these Terms and any other document on the site, these Terms will prevail, except where mandatory local law requires otherwise. You are responsible for ensuring that your use of Mostbet is lawful in your country of residence and that you comply with any local restrictions on online gambling.

Acceptance of Terms

By accessing, registering for, or using any services provided by Mostbet, you expressly accept these Terms in full and without reservation. Acceptance is deemed to occur at the time you tick any checkbox indicating your agreement, click any button labelled with acceptance language (such as “Register” or “I Agree”), or make any real-money deposit into your Mostbet account. You also accept that these Terms may be modified, updated, or supplemented at our sole discretion, within the limits of applicable law and licensing requirements. Where material changes occur, we will make reasonable efforts to notify you via the website, email, or other communication channels, but it remains your responsibility to periodically review the Terms.

If you continue to use Mostbet services after such changes become effective, this will be interpreted as your informed and binding acceptance of the revised Terms. Should you disagree with any modification, your sole remedy is to discontinue using the services and close your account in accordance with the provisions of these Terms. It is your duty to ensure that any contact details provided to us are accurate and up to date so that you can receive notifications regarding changes. You must not use the services if any aspect of these Terms is unclear to you, and you are encouraged to seek independent legal advice if necessary. These Terms are written in English for users in Poland, and any translation, where provided, is for convenience only; in case of discrepancy, the English version for Poland will prevail.

Eligibility & Age Restriction (18+ only)

Use of the Mostbet services is strictly limited to individuals who are at least 18 years of age or the minimum legal age for online gambling in their jurisdiction, whichever is higher. By opening an account, you confirm that you meet this age requirement and that you have full legal capacity to enter into binding agreements. Underage gambling is prohibited and considered a serious breach of these Terms, and we apply a zero-tolerance policy to any attempt by minors to access our services. We reserve the right to request proof of age and identity at any time and to suspend or close any account where we cannot verify that the account holder is 18+ or above the relevant legal age. If we discover or reasonably suspect that an account has been opened or used by a minor, any balance and winnings may be voided, and the account will be closed.

We emphasise that online gambling carries particular risks for young people, including a heightened vulnerability to addiction, impulsive behaviour, and financial harm. For this reason, we take additional measures to detect and prevent underage gambling, including age verification checks, IP analysis, and monitoring for unusual patterns suggestive of minor involvement. Parents and guardians are strongly advised to use parental control software and keep login details, payment cards, and personal documents secure and inaccessible to minors. If you become aware of any minor using or attempting to use the Mostbet services, you must immediately report this to our support team so we can take appropriate action. Any person who facilitates access for an underage individual, for example by sharing credentials or depositing funds on their behalf, will be in serious violation of these Terms and may be reported to the relevant authorities.

Account Registration

To participate in real-money games and services provided by Mostbet, you must complete the account registration process and create a personal user account (“Account”). Registration requires you to provide accurate, complete, and current information, including but not limited to your full name, date of birth, address, email, phone number, and preferred currency. You warrant that all data you submit is truthful and that you will promptly update it whenever changes occur. Mostbet accounts are strictly for personal use by the registered individual and may not be used on behalf of any third party, including family members, friends, or business entities. You are responsible for maintaining the confidentiality of your login details, including username, password, and any two-factor authentication methods, and for all activity conducted under your Account.

Only one Account per person, household, IP address, and device is permitted, unless we expressly allow otherwise in writing. Duplicate accounts, multiple registrations, and shared Accounts are prohibited and may result in the closure of all associated Accounts, forfeiture of any bonuses, and potential confiscation of remaining balances where fraud or abuse is suspected. You must not sell, transfer, or acquire Accounts, nor attempt to access another player’s Account without authorisation. We reserve the right to reject registrations or close Accounts at our sole discretion, particularly where we identify inconsistencies in registration data, suspicious activity, or any breach of these Terms. You accept that your Account may be subject to Know Your Customer (KYC) and anti-money laundering (AML) checks at any time, and that failure to cooperate with such checks may lead to suspension or closure.

Deposits & Withdrawals

Deposits into your Mostbet Account can be made using the payment methods listed on our website, subject to availability in your jurisdiction and any applicable limits. You agree that all funds deposited are derived from lawful sources and that you are the legitimate owner of the payment instruments used. Third-party payments are not allowed, and all deposit methods must be registered in your own name; if we detect a mismatch between the account holder and payment method owner, we may cancel transactions, return funds to the original source, and close or suspend your Account. Deposits are generally credited promptly, but processing times may vary depending on the provider, network conditions, and verification requirements. We do not grant any interest on Account balances, and you must not treat your Mostbet Account as a bank account or financial institution.

Withdrawals are subject to verification checks, wagering requirements (where bonuses are involved), and any additional AML/KYC controls deemed necessary. In general, withdrawals should be made using the same method and payment account used for deposits, where technically and legally possible, in line with AML best practices. We may limit withdrawal amounts per transaction, day, week, or month, and we reserve the right to split payments over several instalments. If you request a withdrawal before meeting any applicable wagering requirements associated with bonuses, such bonuses and any derived winnings may be forfeited. You acknowledge that delays can occur due to external factors such as banking systems, card schemes, cryptocurrency network congestion, or additional security checks, and that Mostbet is not liable for such delays, provided we have acted within a reasonable timeframe.

Payment Methods Table

The following table provides an indicative overview of commonly supported payment methods for deposits and withdrawals. Availability, limits, and processing times may vary depending on your location, currency, and specific payment provider conditions. Always verify details in the cashier section before initiating a transaction.

You acknowledge that currency conversion, where applicable, is performed by the payment provider or financial institution at their own exchange rate and may incur additional costs. We have no control over such rates or charges and accept no responsibility for any losses arising from currency exchange or fluctuations. Chargebacks, payment disputes, and reversals are strictly prohibited and will be treated as a serious breach of these Terms, potentially leading to immediate Account suspension, confiscation of funds, and reporting to relevant financial and regulatory authorities. In case of erroneous deposits (including duplicates), you must inform us without delay; we will attempt to assist in rectifying the situation, but we cannot guarantee reversal of all transactions, particularly outside our systems. We reserve the right to conduct additional checks or withhold withdrawals where large or unusual transactions occur, or where we suspect money laundering, fraud, or other unlawful activity.

Bonuses & Promotions

Mostbet may, from time to time, offer bonuses, free spins, promotional campaigns, loyalty rewards, and other incentives (collectively “Bonuses”) to eligible players. All Bonuses are subject to specific terms and conditions, including but not limited to wagering requirements, game restrictions, time limits, maximum bet limits, and maximum winning caps. Before accepting any Bonus, you must carefully read the corresponding bonus rules published on the promotion page, in your Account area, or otherwise made available. By claiming or automatically receiving a Bonus, you accept that these specific bonus terms become part of your agreement with Mostbet and must be followed in full. Misunderstanding or failure to read the bonus rules does not exempt you from compliance.

Bonuses are intended for genuine recreational play and may not be abused. Prohibited patterns include, but are not limited to, betting strategies aimed solely at clearing wagering requirements with minimal risk, playing games with a negligible house edge or restricted contribution, placing equal bets on opposite outcomes, or colluding with other players to exploit promotional offers. We reserve the right to withhold, cancel, or reclaim Bonuses and associated winnings where we suspect abuse, fraud, or violation of bonus conditions, and to close or restrict Accounts engaging in such practices. Bonuses are usually limited to one per person, household, IP address, device, or payment account, unless otherwise specified. Withdrawals requested before completion of wagering requirements may result in forfeiture of the Bonus and any derived winnings, leaving only your original deposit (subject to our standard withdrawal rules).

We continuously review and adjust our bonus offerings to maintain fair and responsible gaming conditions. This may include changing wagering multipliers, adjusting valid game lists, or ending promotions earlier than planned, subject to applicable law and consumer protection rules. Some Bonuses may require a promotional code, minimum deposit, or manual opt-in; others may be credited automatically to eligible players. It is your responsibility to verify which Bonuses are active on your Account and how they affect real-money and bonus balances. You can monitor the status and progress of active bonuses in the relevant section of your Account dashboard, and you may usually decline or cancel a Bonus before you start wagering with it, in line with our bonus policy.

Game Rules

Each game offered by Mostbet, including Slots, table games, live dealer games, and any other casino or betting products, is governed by specific rules that are available on the game interface or in a dedicated rules section. By participating in a game, you confirm that you have read, understood, and agreed to those rules, and that you accept the outcomes generated by the game’s mechanics and Random Number Generator (RNG), where applicable. Different games may have different return-to-player (RTP) percentages, bet limits, and payout structures; you should familiarise yourself with these characteristics before playing with real money. Game providers may update rules, RTP values, or functionalities from time to time, and such updates will be integrated into our platform without prior individual notice to you. Your continued use of a given game after such changes will be deemed acceptance of the updated rules.

Please note that some games may be unavailable in certain jurisdictions due to licensing, technical, or provider restrictions. Attempting to bypass such restrictions, for example by using VPNs, proxies, or other methods to spoof your location, is strictly forbidden and may result in account suspension and confiscation of winnings. In the event of a discrepancy between a game result displayed on your device and the result recorded on our or the provider’s server, the latter shall prevail, and the official recorded result will be final and binding. If a game malfunctions, is interrupted, or produces an error, all bets and payouts affected by the malfunction will be voided, and the stake amount may be returned to you, subject to the game provider’s rules. You accept that partial or full system failures, although rare, may occur and that our liability is limited as described in the Limitation of Liability section.

Fair Play & RNG

Mostbet is committed to offering fair and transparent gaming, using certified Random Number Generator (RNG) technology for its digital casino games and Slots. RNG systems are designed to ensure that each game result is random, unpredictable, and independent of previous outcomes, and they are typically tested and audited by independent laboratories or certification entities recognised in the online gambling industry. While we rely on reputable third-party providers for many games, we ensure that all games listed on our platform operate in accordance with the relevant rules, payout structures, and fairness standards. You acknowledge that the outcome of all games that rely on RNG is determined by these algorithms and not by any human intervention.

Any attempt by you to manipulate game results, exploit glitches, use bots, scripts, or automated tools to gain an unfair advantage, or otherwise interfere with the fair operation of games is strictly prohibited. Where we detect or reasonably suspect such conduct, we reserve all rights to void bets, cancel winnings, close your Account, and report your activities to relevant authorities or game providers. You understand that your game history, bet records, and transaction logs may be examined as part of routine or targeted integrity checks. We may suspend your Account and hold funds while investigating any potential breach of fair play standards. Our goal is to protect both Mostbet and all honest players from unfair practices while ensuring a level playing field.

Responsible Gambling

Mostbet strongly promotes responsible gambling and is committed to providing tools, information, and support to help players stay in control of their gaming behaviour. Gambling should always be viewed as a form of entertainment, not a way to earn income or solve financial problems. You are encouraged to set personal limits and to play only with money you can afford to lose, never using funds intended for essential living expenses, debts, or savings. We recognise that for a small portion of players, gambling may become problematic or addictive, leading to serious personal, financial, and social consequences. Accordingly, we offer a range of responsible gambling tools and cooperate with professional support organisations to mitigate these risks.

You must monitor your own gambling behaviour and be alert to warning signs such as increasing bet sizes, chasing losses, gambling to escape stress or negative emotions, lying about your gaming, or neglecting work and family responsibilities. If you suspect that gambling is becoming a problem, we encourage you to immediately use the available tools, consider a break or self-exclusion, and seek professional help. We also emphasise the importance of protecting minors by keeping login credentials secure and using parental control software on shared devices. The use of our services by individuals under 18 is expressly prohibited, and responsible adults should actively prevent any underage access to gambling websites. Mostbet reserves the right to contact you with responsible gambling messages, to intervene if we detect patterns of risky behaviour, and to impose certain limits or restrictions where necessary for your protection.

Tools & Features (table)

Mostbet provides several responsible gambling tools to help you manage and control your activity. The availability and exact configuration of these tools may vary by jurisdiction, but the main categories are outlined below.

Support Resources

If you are concerned about your gambling, or the gambling of someone close to you, professional help is available. Mostbet cooperates with reputable international and local organisations that specialise in the prevention and treatment of problem gambling. Generic examples of such support organisations include GamCare, Gambling Therapy, and Gamblers Anonymous, which provide counselling, self-help tools, and group support. We encourage you to contact such organisations if you experience loss of control, anxiety, depression, or financial difficulties related to gambling. Our customer support team can provide information on available help resources, but cannot offer professional psychological, medical, or financial advice.

During a self-exclusion period, you should not attempt to open new Accounts or circumvent the exclusion by using alternative data, and we will take reasonable measures to detect and prevent such attempts. However, you acknowledge that no system can guarantee complete prevention, especially if inaccurate or misleading information is provided; therefore, you also bear responsibility for respecting your own exclusion. If you share your device with others, especially minors or vulnerable persons, we strongly recommend using filtering and blocking software to restrict access to gambling websites. Remember that responsible gambling practices, such as setting deposit limits, not chasing losses, and taking regular breaks, significantly reduce the risk of developing gambling-related harm. Mostbet will continue to update its responsible gambling tools and processes to comply with best practices and regulatory standards.

Prohibited Activities

When using the services of Mostbet, you agree not to engage in any form of unlawful, abusive, or fraudulent conduct. Prohibited activities include, but are not limited to, creating multiple Accounts, using false or stolen identities, providing fake or forged documents during KYC checks, and attempting to access the platform from restricted jurisdictions via VPNs, proxies, or other location-masking tools. Money laundering, terrorist financing, and any use of the platform to transfer or conceal proceeds of crime are strictly forbidden and will be reported to the appropriate authorities where required by law. You must not use bots, scripts, automated betting systems, or any other software that interacts with our systems without explicit written permission. Collusion with other players, manipulation of game outcomes, exploitation of software bugs, and abuse of promotional offers are also prohibited.

You may not harass, threaten, or abuse our staff or other players, including via chat functions, email, or any communication channels associated with Mostbet. Any attempt to compromise the security of the website, including hacking, reverse engineering, introducing malware, or conducting denial-of-service attacks, will be treated as a severe breach and may result in criminal prosecution. Chargebacks, payment disputes initiated in bad faith, or attempting to cancel legitimate deposits or withdrawals constitute fraudulent behaviour and may lead to immediate account closure and confiscation of funds. If we suspect or detect any prohibited activity, we reserve the right to freeze your Account, withhold funds pending investigation, and ultimately terminate your access to the services. You acknowledge that our decisions regarding prohibited activities may rely on internal risk assessments, third-party reports, and transaction monitoring tools.

Restricted Countries (table)

Due to legal, regulatory, or commercial reasons, access to Mostbet services is restricted or prohibited in certain countries and territories. This list may be updated from time to time, and it is your responsibility to ensure that you are not located in a restricted country when using our services. Attempting to access or use Mostbet from a restricted jurisdiction is a breach of these Terms and may lead to account closure and confiscation of funds.

If you move to, or reside in, a restricted country after opening your Account, you must inform us immediately and cease using our services. We may then close or limit your Account in accordance with regulatory obligations. Use of VPNs, proxy servers, or other technical methods to disguise your true location is strictly prohibited and will be treated as a serious breach of these Terms. We reserve the right to perform geo-location checks and IP analysis to verify compliance with territorial restrictions. Our decision regarding your eligibility based on your location will be final, subject to any mandatory legal rights you may have.

Privacy & Data Protection

Mostbet is committed to protecting your personal data and processing it in accordance with applicable data protection laws and regulations. By using our services, you consent to the collection, use, storage, and disclosure of your personal information as described in these Terms and in our dedicated Privacy Policy. We typically collect personal data such as your name, contact information, date of birth, identification documents, transaction history, device details, and behavioural data related to your use of the website and apps. This information is used for purposes including account creation and management, verification (KYC), responsible gambling monitoring, fraud and AML checks, customer support, marketing (where permitted), and compliance with legal and regulatory obligations. We apply technical and organisational security measures to protect your data against unauthorised access, alteration, disclosure, or destruction.

Your data may be shared with trusted third parties, such as payment providers, identity verification services, AML screening providers, game developers, IT and analytics services, and regulatory or law enforcement authorities where required by law. Some of these parties may be located outside your country of residence, including outside the European Economic Area, in which case we will implement suitable safeguards, such as standard contractual clauses, where required by applicable law. We retain your personal data for the period necessary to fulfil the purposes for which it was collected, including any mandatory retention periods under AML or gambling regulations, which may extend for several years after account closure. You have certain rights in relation to your personal data, such as the right to access, rectify, and, in some circumstances, delete or restrict its processing, as well as the right to object to certain processing and to withdraw consent for marketing communications.

We use cookies and similar technologies to enhance your experience, remember your preferences, perform analytics, and provide personalised content and offers. You can manage your cookie settings via your browser or device, although disabling certain cookies may affect the functionality of the website and your ability to use some services. It is your responsibility to ensure that all information you provide is accurate and up to date; we are not liable for consequences arising from incorrect data supplied by you. If you believe that your data protection rights have been violated, you have the right to lodge a complaint with the relevant supervisory authority in your jurisdiction, without prejudice to any other administrative or judicial remedy. For more detailed information, please refer to the full Privacy Policy accessible from the Mostbet website.

Account Suspension & Termination

Mostbet reserves the right to suspend, restrict, or terminate your Account at its sole discretion, subject to applicable law and regulatory obligations. Common reasons for suspension or termination include, but are not limited to, breach of these Terms, provision of false or misleading information, failure to complete KYC checks, suspected fraud or money laundering, use of prohibited payment methods or third-party funds, and evidence of underage gambling. During a suspension, you may be temporarily unable to place bets, play games, or make withdrawals until the matter is resolved. In more serious cases, we may permanently close your Account, in which event we will usually return any legitimate remaining balance to you, subject to legal and regulatory constraints and any right we may have to withhold funds arising from unlawful activity or breach of these Terms.

You may also request closure of your Account at any time by contacting our customer support or using the available settings, where such functionality is provided. Before closure, we may ask you to withdraw any remaining funds or provide instructions regarding the transfer of your balance, in accordance with our standard withdrawal procedures. Please note that voluntary account closure is distinct from self-exclusion for responsible gambling reasons, which involves additional safeguards and may require a minimum exclusion period. Where multiple Accounts are discovered, we may close all such Accounts and treat any bonuses or illegitimately gained funds as void. Any outstanding obligations or liabilities incurred prior to suspension or termination, including unsettled bets or disputes, will survive and remain subject to these Terms.

Limitation of Liability

To the maximum extent permitted by applicable law, Mostbet provides the services on an “as is” and “as available” basis and makes no warranties or representations, express or implied, regarding their uninterrupted availability, accuracy, reliability, or suitability for any particular purpose. While we take reasonable steps to maintain a secure and functional platform, we do not guarantee that access will be free from errors, delays, viruses, or other harmful components, nor that any defects will be corrected immediately. You acknowledge that you use the services at your own risk and that any financial losses resulting from gameplay, network issues, or device malfunctions are your sole responsibility, subject only to mandatory consumer protection rights that may apply.

Under no circumstances shall Mostbet, its affiliates, directors, employees, or agents be liable for any indirect, incidental, consequential, special, or punitive damages arising out of or in connection with your use of the services, including but not limited to lost profits, loss of data, interruption of business, or damage to reputation, even if advised of the possibility of such damages. Our total aggregate liability to you for any claim or series of related claims shall not exceed the amount of your net deposits made to your Account over the 30 days immediately preceding the event giving rise to the claim, to the extent permitted by law. Nothing in these Terms shall exclude or limit liability for death or personal injury caused by negligence, fraud, or any other liability that cannot be excluded or limited under applicable law. You are responsible for ensuring that your equipment, internet connection, and software are compatible with our services and for any costs incurred in accessing the website.

If you experience a disconnection or technical problem while playing, the outcome recorded on our server will be considered final. Where appropriate, we may restore the game state to its last known status, but we are not obligated to compensate for losses of gameplay time or opportunity. We may temporarily suspend the services for maintenance, updates, or security checks, and while we seek to minimise disruption, we are not liable for any inconvenience or losses you may experience as a result. Your statutory rights as a consumer, where applicable, remain unaffected by this Limitation of Liability clause.

Complaints & Dispute Resolution

Mostbet aims to provide a high standard of service, but should you have any complaint regarding our services, you are encouraged to contact customer support using the channels indicated on the website. When submitting a complaint, you should provide your Account details, a clear description of the issue, relevant dates and times, and any supporting evidence such as screenshots or transaction references. We will acknowledge receipt of your complaint within a reasonable timeframe and endeavour to investigate and respond as promptly as possible. Our initial goal is to resolve complaints amicably and transparently, in line with these Terms and any applicable regulatory requirements. You agree to cooperate with our support team by providing any further information reasonably requested during the investigation.

If you are dissatisfied with the outcome of your complaint, you may request that the matter be escalated internally for further review. In some jurisdictions, you may also have the right to submit the dispute to an independent Alternative Dispute Resolution (ADR) body or to the relevant regulatory authority, in accordance with local rules. Details of any applicable ADR procedures or regulators, where relevant, may be provided upon request or made available on the website. While a complaint is under investigation, we may temporarily suspend certain transactions or gameplay related to the disputed matter, but we will seek to avoid unnecessary interruption to your general use of the services. Nothing in this section limits your right to pursue legal remedies through the courts of competent jurisdiction, subject to the Governing Law clause below.

Governing Law

These Terms and your use of the Mostbet services shall be governed by and construed in accordance with the laws of the jurisdiction in which the operating company behind Mostbet is incorporated, unless mandatory consumer protection or gambling laws in your country of residence require otherwise. In the event of any conflict between the governing law and non-mandatory local law, the governing law shall prevail, except where local law provides you with greater protection that cannot legally be waived. You agree that any disputes, claims, or controversies arising out of or related to these Terms, your Account, or your use of the services shall be subject to the exclusive or, where applicable, non-exclusive jurisdiction of the courts of the governing law jurisdiction. Nothing in this clause shall prevent you from bringing a claim in the courts of your country of residence where mandatory consumer protection laws so decree.

If any provision of these Terms is found to be invalid, unlawful, or unenforceable by a court or competent authority, such provision shall be severed from the remaining Terms, which shall continue to be valid and enforceable to the fullest extent permitted by law. The failure of Mostbet to enforce any right or provision under these Terms shall not be construed as a waiver of such right or provision. You are responsible for ensuring that your access to and use of the services does not violate any local laws or regulations applicable in your jurisdiction. Should a dispute arise concerning the interpretation of these Terms, the English version applicable to Poland shall prevail over any translations.

Final Provisions

Mostbet reserves the right to modify, update, or discontinue any part of the website, services, games, or these Terms at any time, subject to applicable law and regulatory requirements. Where changes are material, we will use reasonable efforts to notify you, for example via on-site messages or email, but you remain responsible for regularly reviewing the Terms. Continued use of the services after such changes take effect constitutes your acceptance of the updated Terms. If you do not agree with any modification, you must immediately stop using the services and close your Account in accordance with the procedures outlined above. No oral statement or communication from our staff shall modify these written Terms unless expressly confirmed in writing by an authorised representative.

You may not assign, transfer, or delegate any of your rights or obligations under these Terms without our prior written consent. We may assign or transfer our rights and obligations, in whole or in part, to another entity as part of a reorganisation, merger, acquisition, or other corporate transaction, provided that such assignment does not reduce the level of protection afforded to you under these Terms and applicable law. These Terms, together with the Privacy Policy, game rules, bonus conditions, and other documents expressly incorporated by reference, constitute the entire agreement between you and Mostbet regarding the use of the services. Any headings used in these Terms are for convenience only and shall not affect their interpretation. For further information about our services, responsible gambling resources, or legal policies, please refer to the relevant sections of Mostbet.
