Introduction

These Terms and Conditions (the “Terms”) govern the use of the online casino, sports betting, and related services offered under the brand name Mostbet (“Mostbet”, “we”, “us”, “our”). By opening an account at Mostbet and using any services on our website or mobile applications, you enter into a legally binding agreement with us and accept these Terms in full. The purpose of these Terms is to set out your rights and obligations as a player, as well as our rights and obligations as the operator, in a clear and transparent manner. These Terms apply to all gaming activities offered by Mostbet, including but not limited to Slots, table games, live casino, crash games, instant games, and any other current or future products. You must read these Terms carefully before registering or placing any deposits, as they contain important information about responsible gambling, age restrictions, payments, bonuses, privacy, and dispute resolution. If you do not agree with any part of these Terms, you must not create an account or use any services offered by Mostbet. Continued use of the services will be deemed as full and ongoing acceptance of these Terms, including any future amendments.

Mostbet operates in accordance with applicable online gambling regulations and international standards for responsible gaming, anti-money laundering (AML), and player protection. We are committed to providing a safe, fair, and transparent gaming environment for adult players from permitted jurisdictions. Our services are strictly limited to individuals who have reached the legal age for online gambling, which is a minimum of 18 years. We strongly support responsible gambling principles and take measures to help players stay in control of their gaming activity and avoid gambling-related harm. These Terms are complemented by our Privacy Policy, KYC/AML Policy, Bonus Rules, and other policies, which collectively form part of your agreement with us. In case of any conflict between translations, the English version of the Terms shall prevail.

Acceptance of Terms

By registering an account and clicking the “Register”, “Sign Up”, or similar button on the Mostbet website or mobile app, you explicitly confirm that you have read, understood, and agreed to be bound by these Terms and any documents incorporated by reference. Acceptance of these Terms is a prerequisite for accessing or using our services, and you may not proceed with registration or gaming activities unless you provide your informed consent. You also acknowledge that the rules of specific games, as well as special promotional or bonus terms, form an integral part of these Terms and must be complied with at all times. Your use of the services after any update or modification of the Terms constitutes your continued acceptance of the revised version, even if you have not read the updated text in full. It is your responsibility to regularly review the Terms and related policies to stay informed about any changes that may affect your rights and obligations.

If you disagree with any provision of these Terms at any stage, you must immediately stop using the services, close your account, and request account closure in accordance with the procedures described herein. We reserve the right to refuse registration, close an account, or restrict services to any user at our sole discretion, subject to applicable law and without any obligation to provide a detailed explanation. You confirm that you use the services on your own initiative and that you are not acting on behalf of any other person, company, or organization. You also agree that you will not challenge the legal validity of these Terms on the grounds of having not fully read or understood them prior to using the services. In all disputes relating to your acceptance or understanding of these Terms, the records held by Mostbet will be treated as final and binding, subject to your statutory rights.

Eligibility & Age Restriction (18+ only)

Access to and use of Mostbet services is strictly limited to individuals who are at least 18 years old, or who have reached the minimum legal gambling age in their country of residence, whichever is higher. By registering an account, you warrant that you are not under the age of 18 and that you have full legal capacity to enter into binding agreements. We take the prevention of underage gambling extremely seriously and implement technical, procedural, and verification measures to detect and block access by minors. Any attempt by an underage individual to open an account, deposit funds, or participate in games is strictly prohibited and constitutes a serious breach of these Terms. If we discover or reasonably suspect that you are underage, or that your account has been used by a minor, we will immediately suspend the account, cancel any bets and winnings, and return any deposited funds to the extent permitted by law.

You acknowledge that online gambling can pose specific risks to young people, including the potential development of unhealthy habits, financial problems, and negative impact on mental health, education, and social relationships. You therefore agree not to allow any minor to access your account or use your devices to play at Mostbet, and you undertake to keep your login credentials safe and secure. Parents and guardians are strongly encouraged to use parental control tools and content filters to restrict access to gambling websites and applications on shared devices. We may request additional documents and verification steps to confirm your age and identity at registration, during account activity, and prior to processing withdrawals. Providing false or misleading information about your age or identity, or using forged or third-party documents, is strictly prohibited and may result in account closure, forfeiture of winnings, and notification to relevant authorities.

Account Registration

To access real-money services at Mostbet, you must create a personal player account by completing the registration process on our website or mobile app. During registration, you will be asked to provide accurate and complete information, including but not limited to your full name, date of birth, country of residence, address, phone number, email address, and preferred currency. You must ensure that all data provided is true, current, and not misleading, and you must promptly update any changes by editing your profile or contacting customer support. Each player is allowed to open and maintain only one account with Mostbet; multiple or duplicate accounts, whether under your own name or under different identities, are strictly forbidden. If we detect duplicate accounts, we may close or merge them, cancel bonuses and winnings, and retain balances where we suspect abuse, fraud, or violation of these Terms.

Your Mostbet account is for personal use only and must not be shared, transferred, sold, or used by third parties, including family members, friends, or business associates. You are solely responsible for maintaining the confidentiality of your login credentials and for all actions taken under your account, regardless of whether you personally performed them. If you suspect that your account has been compromised, or that your credentials have been disclosed to a third party, you must immediately change your password and contact customer support. We may, at our discretion, request additional verification, temporarily suspend your account, or freeze transactions while we investigate any suspicious activity. You agree that we may reject a registration request or close an existing account if we have reasonable grounds to believe that the information provided is false, that the account is being misused, or that our services may be abused or used for illegal purposes.

Deposits & Withdrawals

To participate in real-money games, you must deposit funds into your Mostbet account using one of the available payment methods listed in the cashier section. All deposits must be made from payment instruments held in your own name, and third-party payments are not allowed. By initiating a deposit, you confirm that you are authorized to use the selected payment method and that the funds originate from legitimate sources. Mostbet does not charge deposit fees; however, your bank, card issuer, e-wallet, or crypto service provider may apply transaction charges or currency conversion fees, for which we are not responsible. Deposited funds are usually credited instantly or within a short period, depending on the method, but in some cases delays may occur due to banking or network issues beyond our control. We reserve the right to set minimum and maximum deposit limits, which may vary depending on the payment method, currency, and your player status.

Withdrawals can be requested from the cashier section, subject to our verification, KYC/AML checks, and compliance with these Terms. Before processing the first withdrawal, we are required to verify your identity by requesting documents such as ID card, passport, driving licence, proof of address, and, where necessary, evidence of source of funds. We may also require selfie or video verification in line with our KYC standards. Withdrawals are, whenever possible, processed via the same payment method used for deposits, in line with anti-money laundering rules and risk management procedures. We may impose minimum and maximum withdrawal limits per transaction, per day, per week, or per month, depending on internal policies, payment method restrictions, and your account status. Withdrawals may be temporarily put on hold or subject to additional checks if we identify unusual, high-risk, or potentially fraudulent activity, or if you attempt a chargeback or reversal of a payment.

You acknowledge that currency conversion, if applicable, is performed by your payment provider at their own exchange rates and under their own terms, and that Mostbet is not responsible for any exchange rate differences or additional fees. We do not provide interest on any funds held in your account, whether deposited or pending withdrawal. You must not use your Mostbet account as a bank account or as a means of transferring funds to third parties. In some cases, we may require that wagering requirements be met before allowing withdrawal of deposited funds, especially if a deposit was made in connection with a bonus or promotion. We reserve the right to refuse or delay withdrawals if you have violated these Terms, if your account is under investigation, or if we are required to do so by law or by request of competent authorities.

Payment Methods Table

The payment methods available to you may vary depending on your country, currency, and local regulations, and the exact limits and timescales will be displayed in your personal cashier section. You agree to consult the cashier before making any transaction, so that you are fully informed of the current options and conditions.

Bonuses & Promotions

Mostbet may, from time to time, offer bonuses, free spins, cashback, tournaments, and other promotions to new and existing players, including the welcome offer such as a first deposit bonus (for example, 100% + 200FS, where available). All bonuses and promotions are subject to specific terms and conditions that are additional to these general Terms and are published on the relevant promotional pages. By accepting a bonus, whether automatically or by opting in, you agree to be bound by the specific bonus rules, including wagering requirements, maximum bet limits, game restrictions, validity periods, and withdrawal conditions. Bonuses are intended for recreational play and must not be abused or used for systematic profit-making through bonus hunting, collusion, or other prohibited strategies. If we have reasonable grounds to believe that you are abusing a bonus, engaging in low-risk wagering patterns, or violating the spirit of a promotion, we may remove the bonus, cancel associated winnings, and restrict your eligibility for future offers.

You may usually monitor the status and progress of your active bonuses in the “My Account” or “Bonuses” section, where you will find details such as remaining wagering requirements, time left until expiry, and eligible games. Some promotions may be limited to specific games, such as selected Slots, live casino titles, or seasonal events, and bets placed on excluded games will not contribute to wagering. Furthermore, some offers may be available only once per person, household, IP address, payment method, or device, in order to prevent bonus abuse. If bonuses are credited to your account by mistake, due to a technical error or incorrect configuration, we reserve the right to remove such bonuses and void related winnings, and you agree to cooperate in correcting the error. Unless explicitly stated otherwise, bonuses and promotional funds cannot be withdrawn directly; they must first be converted to real money by meeting the applicable wagering requirements.

You are responsible for reading the specific rules of each promotion before participating, and for ensuring that you understand how the offer works and how to qualify for it. We reserve the right to modify, suspend, or cancel any bonus or promotion at any time, including for individual players or groups of players, if necessary to ensure fairness, compliance with regulations, or prevention of abuse. In the event of any discrepancy between the promotional text and the detailed bonus terms, the detailed terms shall prevail. Some promotions may be restricted based on your country, currency, or player profile, and we may apply personalised offers based on your activity and preferences. We also provide information and links, such as Mostbet Bonuses, where you can review active offers targeted to your region in detail.

Game Rules

Each category of games offered by Mostbet, including Slots, table games, live casino, and other titles, is governed by specific rules and mechanics that you must read and understand before placing bets. Game rules are typically available within the game interface or in the help section, and they cover aspects such as paytables, winning combinations, return to player (RTP) rates, minimum and maximum bets, and special features. You agree to familiarize yourself with these rules and not to rely solely on assumptions or external sources. If you participate in live casino games, you must also comply with the instructions of the live dealer and the house rules set by the game provider. Any attempt to gain an unfair advantage by exploiting rule ambiguities, interface vulnerabilities, or technical glitches is strictly prohibited and may result in bet cancellation, account suspension, and reporting to relevant authorities.

Mostbet reserves the right to change, remove, or temporarily disable any game at any time for maintenance, technical, legal, or operational reasons. In such cases, we will, where feasible, complete any ongoing game rounds and settle resolved bets in accordance with the game outcome. Bets placed after a game malfunction, or clearly affected by a technical error, will be considered invalid and may be refunded. In some cases, game providers may decide outcomes based on their own logs and records in the event of disputes, and such decisions will be considered final and binding, subject to applicable law. You accept that game results displayed on your screen may be provisional until confirmed on our servers and that server records shall prevail in determining the final outcome.

Fair Play & RNG

Mostbet is committed to ensuring fair play and the integrity of all games available on the platform. The outcomes of our virtual casino games, including Slots and random-number-based table games, are determined by certified Random Number Generator (RNG) technology. The RNG ensures that each spin, deal, or result is random and independent from previous rounds, and that neither the player nor the operator can predict or manipulate outcomes. Leading third-party testing laboratories and certification bodies audit the RNG and game mathematics of our providers to confirm compliance with international standards, fairness requirements, and expected return-to-player percentages. We publish RTP information where available, but you acknowledge that actual results in the short term will vary significantly compared to theoretical probabilities.

Players must not attempt to interfere with, reverse engineer, or manipulate the software, RNG, or game mechanics in any way. The use of bots, scripts, automated tools, or artificial intelligence for gameplay is expressly prohibited. If we detect or have reasonable grounds to suspect that such tools or methods have been used, we may void bets, confiscate winnings, and permanently close the account. You agree that in the case of apparent or suspected manipulation of a game result, server logs, game provider records, and independent test results will be considered conclusive evidence. Any dispute relating to game fairness will be investigated thoroughly, and we may, where appropriate, share relevant technical information with regulators or dispute resolution bodies in an anonymised form.

Responsible Gambling

Mostbet promotes responsible gambling as a core part of its corporate philosophy and player protection strategy. Gambling is intended to be a form of entertainment for adults and should never be viewed as a way to make money, solve financial problems, or escape personal difficulties. We recognise that a small proportion of players may develop problematic gambling behaviour, and we offer a range of tools, features, and support resources to help you stay in control. You are encouraged to set personal limits, monitor your time and spending, and seek assistance if you notice any warning signs such as chasing losses, neglecting responsibilities, or gambling with borrowed money. We strongly advise players in Poland and other jurisdictions to familiarise themselves with responsible gaming principles and to approach gambling as a controlled leisure activity with a predefined budget and time allocation.

Mostbet provides various tools which you can activate at any time through your account settings or by contacting customer support. These tools include deposit limits, loss limits, wagering limits, session reminders, time limits, temporary cooling-off periods, and long-term self-exclusion options. Once set, some limits may be reduced immediately but increased only after a cooling-off period, in order to prevent impulsive decisions. During self-exclusion, your account will be blocked for gambling activities, and you will not receive marketing communications, to the extent technically possible. We also use monitoring systems to identify patterns of potentially harmful play and may proactively contact you with advice or suggestions to adjust your limits.

Gambling under the age of 18 is strictly prohibited and can have severe negative consequences for young people, including the development of addiction, difficulties at school or work, and social and emotional problems. We take steps to prevent underage access, but parents and guardians share the responsibility for protecting minors by using parental control solutions and by educating young people about the risks of gambling. If you suspect that a minor may be using our services, you must immediately report this to us so that appropriate measures can be taken. We cooperate with recognised organisations and charities that provide counselling, treatment, and support for individuals affected by gambling problems. These organisations may include, for example, GamCare, Gambling Therapy, and Gamblers Anonymous, as well as national helplines and counselling services in your country.

Tools & Features (table)

Support Resources

If you feel that your gambling is becoming problematic or that you are losing control, you should immediately stop playing and consider seeking professional help. Mostbet recommends that you review educational materials on responsible gaming and complete self-assessment questionnaires that help identify harmful patterns. If the self-assessment indicates potential risk, you should consider using our tools such as self-exclusion and setting strict financial and time limits. In addition, you can contact independent support organisations that provide confidential advice, counselling, and treatment services for gamblers and their families. Such organisations may include international services like GamCare, Gambling Therapy, and Gamblers Anonymous, as well as local helplines and support centres in Poland and other countries.

When you contact our customer support to discuss gambling-related concerns, our team will treat your situation with sensitivity and confidentiality, within the limits of legal obligations. We may suggest appropriate responsible gaming tools, provide information on support organisations, and, where necessary, implement restrictions on your account. You should understand that preventing gambling-related harm is a shared responsibility and that your active cooperation is essential. If you are under treatment for gambling problems, you should inform us so that we can apply long-term protective measures such as permanent closure or extended self-exclusion. Family members and friends of players who show signs of problematic gambling are also encouraged to contact professional support organisations to receive guidance on how best to help.

Prohibited Activities

Mostbet strictly forbids any illegal, fraudulent, or abusive activities on its platform. You must not engage in money laundering, terrorist financing, fraud, identity theft, or any other unlawful conduct when registering, depositing, or playing. You are prohibited from opening multiple accounts, using fake or forged documents, or providing false information for verification or payment purposes. The use of bots, scripts, automated betting tools, or any third-party software that interacts with our systems without explicit authorisation is strictly banned. Collusion with other players, manipulation of game outcomes, and exploitation of software bugs or system errors for advantage are also regarded as serious violations.

Chargebacks or payment reversals requested without legitimate cause, particularly as a means to obtain funds after gambling, are considered fraud. If a chargeback is initiated, we reserve the right to suspend or close your account, recover any associated costs, and notify financial institutions or relevant authorities. The use of VPNs, proxy servers, or any other tools to disguise your real location or to bypass geographic restrictions is prohibited. Harassment, abusive language, or threatening behaviour towards customer support staff, dealers, or other players will not be tolerated and may result in account sanctions. Any breach of this section may lead to cancellation of bets, confiscation of winnings, account closure, and legal action where appropriate.

Restricted Countries (table)

Mostbet’s services are not available in certain countries and territories due to legal, regulatory, or commercial reasons. You are responsible for ensuring that you are not located in a restricted jurisdiction and that your use of our services complies with the laws of your country. You must not use VPNs, proxies, or other methods to circumvent geographic blocks or to falsely represent your location.

This table is provided for general information only and does not constitute an exhaustive or definitive list. We may update our restricted country list at any time based on regulatory changes, risk evaluations, or licensing requirements. If we discover that you have provided false information about your location, or that you are accessing from a restricted country, we may immediately suspend your account, cancel bets, and refund or retain funds in accordance with applicable law and our regulatory obligations.

Privacy & Data Protection

Mostbet is committed to protecting your privacy and handling your personal data in a lawful, fair, and transparent manner, in line with applicable data protection regulations. When you register and use our services, we collect and process certain personal information, including identification data, contact details, transactional data, and information about your gaming activity. This data is used to manage your account, process payments, deliver services, prevent fraud, comply with AML and KYC requirements, and, where you consent, provide marketing communications and personalised offers. We may also use cookies and similar technologies to enhance your user experience, remember your preferences, and gather analytical data about how our website and apps are used.

Your personal data may be shared with carefully selected third parties such as payment providers, identity verification services, AML monitoring tools, game providers, analytics services, and competent authorities where required by law. All such transfers are carried out under appropriate contractual safeguards, ensuring that your data is processed securely and only for legitimate purposes. In some cases, your data may be transferred outside your country or outside the European Economic Area, subject to adequate protection measures such as standard contractual clauses or equivalent safeguards. We retain your data for as long as necessary to fulfil the purposes for which it was collected and to comply with legal, regulatory, and anti-money laundering obligations, which may require keeping certain records for a number of years after account closure.

You have a range of rights in relation to your personal data, including the right to access, correct, or update your information, the right to request deletion or restriction of processing in certain circumstances, the right to object to processing based on legitimate interests, the right to data portability, and the right to withdraw consent for marketing at any time. You may exercise these rights by contacting our customer support or our designated data protection contact, as described in the Privacy Policy. If you believe that your data protection rights have been violated, you have the right to lodge a complaint with a competent supervisory authority, such as the data protection regulator in your country. For more detailed information on how we collect, use, and protect your personal data, you should consult our dedicated Privacy Policy, which forms an integral part of these Terms and is available via the Mostbet website.

Account Suspension & Termination

Mostbet reserves the right to suspend or terminate your account at any time in accordance with these Terms, regulatory requirements, and our internal risk and compliance policies. Suspension may be temporary or indefinite and can occur for various reasons, including but not limited to suspected fraud, money laundering, underage gambling, use of prohibited tools, bonus abuse, or violation of any clause of these Terms. During suspension, you may be prevented from logging in, depositing, withdrawing, or placing bets, while we conduct an investigation. Depending on the outcome of the investigation, we may either lift the suspension, apply restrictions, or proceed to permanently close the account. Where legally required or appropriate, we may report suspicious activity to relevant authorities or financial institutions.

You have the right to request closure of your account at any time by contacting customer support and following the prescribed procedure. Before closure, we may ask you to withdraw any remaining balance, provided there are no restrictions or pending investigations. Upon termination, whether initiated by you or by us, your rights to use the services cease immediately, and any ongoing bets or promotions may be settled or cancelled according to our policies and legal obligations. We may retain certain information and transaction records after closure to comply with legal and regulatory requirements, including AML and responsible gaming obligations. In cases where we have reasonable grounds to suspect serious violations, we may withhold funds on the account pending investigation and, where permitted by law, retain some or all funds to cover damages, costs, or regulatory penalties.

Limitation of Liability

You acknowledge that you use the Mostbet services at your own risk and that the games are provided “as is” and “as available” without any express or implied warranties of uninterrupted availability or freedom from errors. While we take reasonable steps to ensure that our systems are secure, reliable, and functioning correctly, we cannot guarantee that access will be continuous, that the website or apps will be free of bugs, or that technical problems will never occur. To the fullest extent permitted by law, Mostbet, its affiliates, directors, employees, and partners shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or in connection with your use of the services. This includes, but is not limited to, loss of profits, loss of data, loss of opportunity, or damage to goodwill, even if we have been advised of the possibility of such damages.

Our total aggregate liability to you for any claim arising under or in connection with these Terms, your account, or your use of the services, whether in contract, tort, or otherwise, shall be limited to the lesser of (i) your net losses on the account over the 30 days preceding the event giving rise to the claim or (ii) a reasonable amount defined by applicable law. Nothing in these Terms shall exclude or limit our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded under applicable law. You agree that you are solely responsible for verifying whether your use of Mostbet services complies with the laws of your jurisdiction and that we bear no responsibility for your breach of local regulations. You also acknowledge that gambling may lead to financial loss and that you are fully and solely responsible for any such losses arising from your participation.

Complaints & Dispute Resolution

If you have any concerns, questions, or complaints regarding our services, you should first contact our customer support team via the channels indicated on the website, such as live chat or email. When submitting a complaint, you should provide clear and accurate information, including your account details, a detailed description of the issue, relevant screenshots or transaction IDs, and your preferred resolution. We will acknowledge receipt of your complaint within a reasonable period and will make every effort to investigate and respond substantively within a time frame aligned with our internal policies and applicable regulations. During the investigation, we may request additional information or documentation from you, and you agree to cooperate in good faith.

If, after our internal review, you are not satisfied with the outcome, you may have the right to escalate the matter to an independent dispute resolution body or to the relevant regulatory authority, where such mechanisms are available and applicable. We will provide information on the appropriate escalation channels in our final response, where required by law. You agree that our records, including server logs, transaction histories, and communications, shall be deemed final and conclusive evidence in the event of a dispute concerning the outcome of bets, account balances, or the interpretation of these Terms, subject to any contrary decision by a competent authority. Complaints regarding game outcomes may also be referred to the respective game provider or independent testing laboratories for technical evaluation where necessary. You should submit complaints as soon as reasonably possible after the issue arises; undue delay may affect our ability to investigate fully and may, in some cases, result in rejection of the complaint if mandated time limits have expired under applicable rules.

Governing Law

These Terms, your account, and any dispute or claim arising out of or in connection with them or with your use of the Mostbet services shall be governed by and construed in accordance with the laws of the jurisdiction of incorporation or licensing of the operator responsible for the Mostbet brand, unless mandatory local laws in your country of residence provide otherwise. In the event of any discrepancy between these Terms and any mandatory provisions of national law applicable to consumer contracts, such mandatory provisions shall prevail to the extent of the conflict. You agree that, subject to any applicable consumer protection rules regarding jurisdiction, the courts of the operator’s jurisdiction shall have non-exclusive jurisdiction to settle any disputes arising from or relating to these Terms or the services. Nothing in this clause limits your right, where applicable law so provides, to bring proceedings in the courts of your place of residence.

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a competent court or authority, such provision shall be modified to the minimum extent necessary to make it valid and enforceable, or, if this is not possible, it shall be deemed deleted, and the remaining provisions shall continue in full force and effect. The failure of Mostbet to exercise or enforce any right or provision of these Terms shall not constitute a waiver of such right or provision. You may not assign or transfer any of your rights or obligations under these Terms without our prior written consent, whereas we may assign or transfer our rights and obligations to another entity, provided that such assignment does not adversely affect your statutory rights as a consumer.

Final Provisions

These Terms constitute the entire agreement between you and Mostbet regarding the use of the services and supersede any prior or contemporaneous agreements, understandings, or communications, whether written or oral, relating to the subject matter hereof. Any ancillary documents, including but not limited to the Privacy Policy, KYC/AML Policy, Bonus Rules, and Game Rules, form an integral part of these Terms, and references to “Terms” shall be interpreted accordingly. We reserve the right to amend or update these Terms at any time, for example, to reflect changes in legal or regulatory requirements, to introduce new products or services, or to improve clarity and player protection. Whenever we make material changes, we will take reasonable steps to notify you, such as publishing the updated version on our website, displaying a notice at login, or sending an email message.

Your continued use of the services after the effective date of the updated Terms will constitute your acceptance of the changes. If you do not agree with the updated Terms, you must stop using our services and request closure of your account. In interpreting these Terms, headings are for convenience only and do not affect the meaning or scope of provisions. In any case of doubt or ambiguity, the version published in English shall prevail over other language versions. By registering and playing at Mostbet, you confirm that you have read, understood, and accepted these Terms, that you meet all eligibility requirements including the 18+ age restriction, and that you will use the services in a responsible and lawful manner at all times.
