Introduction

These Terms and Conditions (the “Terms”) constitute a legally binding agreement between you as a Player and the operator of the online casino and sports betting platform branded as “Mostbet” (“Mostbet”, “we”, “us”, “our”). By accessing, registering or using any services, games or products offered under the Mostbet brand, you confirm that you have read, understood and accepted these Terms in full. These Terms apply to all real-money and demo play on the website, mobile site and any mobile applications associated with Mostbet, including Casino, Slots, live dealer games, and any additional features. The purpose of these Terms is to ensure a transparent, safe, and fair gambling environment, with a particular focus on responsible gaming and compliance with applicable laws and regulations. If you do not agree with any provision of these Terms, you must not register, must not open an account, and must not use our services. We strongly recommend that you print or save a copy of these Terms for your records and review them regularly, as they may change from time to time in accordance with the provisions below.

Mostbet is intended strictly for adult entertainment and may only be used by persons who are 18 years of age or older, or who have reached the legal age of gambling in their jurisdiction, whichever is higher. We recognise that online gambling carries financial and psychological risks, and we therefore emphasise responsible gambling practices in all aspects of our operations. Mostbet implements technical and organisational measures to reduce the risks of problem gambling, including limits, cooling‑off periods and self‑exclusion tools, which are described in detail later in these Terms. Nevertheless, you remain solely responsible for your gambling decisions and for ensuring that your participation is lawful in your country of residence. These Terms are drafted in English as used for players based in Poland and are intended to be clear, comprehensive and in line with recognised best practices in the online gambling industry.

Acceptance of Terms

By creating a Player Account, clicking “Register”, “I agree”, “Sign up” or a similar button, or by otherwise using the services of Mostbet, you expressly acknowledge that you have read, understood and accepted these Terms and our Privacy and Cookie policies. Your acceptance extends to all game rules, bonus rules, payment rules, and any additional policies referenced in these Terms or presented on the Mostbet website. If you use the services on behalf of a third party or any other person, you confirm that you have the authority to bind that person to these Terms, and both you and that person will be jointly responsible. You also confirm that you are acting for yourself and not as a representative or agent of any other person, company or entity. If at any time you disagree with these Terms or any future modification, your sole remedy is to stop using the services, close your account, and request withdrawal of any remaining real‑money balance, subject to verification and applicable rules.

Your continued use of the Mostbet website, mobile platform or apps after any update or change to these Terms has been published will be deemed acceptance of the revised Terms. It is your responsibility to check the Terms on a regular basis to verify whether amendments have been introduced. We may notify you of material changes via email, on‑site messages, or pop‑up notifications, but we are not legally obliged to do so in every case; posting the updated Terms on the site will be sufficient for the changes to take effect. If you do not wish to be bound by any revised Terms, you must immediately stop using the services and contact customer support to close your account. No verbal or written statement from customer support or any other representative of Mostbet may override or modify these Terms unless expressly stated in a formal amendment published on the website.

Eligibility & Age Restriction (18+ only)

Access to and use of Mostbet is strictly limited to adults who are at least 18 years old, or have reached the minimum legal age for gambling in their jurisdiction, whichever is higher. By opening an account and using our services, you confirm that you meet this age requirement and that you have full legal capacity to enter into binding contracts. We reserve the right to request documents to verify your age at any time, particularly before processing withdrawals, activating certain bonuses, or if we have any reason to suspect that you may be underage. Providing false information regarding your age or identity constitutes a serious breach of these Terms and may result in immediate closure of your account, cancellation of bets, confiscation of winnings and notification to relevant authorities. Parents and guardians are strongly advised to monitor and restrict access to devices used by minors in order to prevent underage gambling.

Mostbet implements technical and procedural measures to reduce the risk of underage participation, including age‑verification checks, verification of identity documents, and monitoring for suspicious account behaviour. However, no system is foolproof, and we rely on the accuracy and honesty of the information provided by our Players. If we discover or reasonably suspect that an account has been created or used by an underage person, we will immediately suspend the account while we investigate. If underage gambling is confirmed, we will close the account, refund any deposits made from the same source of funds wherever possible (minus any withdrawals already paid), and void all winnings and bonus funds. Underage gambling carries particularly serious risks for young people, including addiction, debt, and negative impact on mental health and education; therefore, we will always apply a strict zero‑tolerance approach in such cases.

Account Registration

To participate in real‑money games and services offered by Mostbet, you must first complete the registration process and open a personal Player Account. Registration requires you to provide accurate and complete information, including but not limited to your full name, date of birth, residential address, email address, phone number, and a secure password. You may also be required to choose your account currency from the list available at the time of registration; once chosen, the currency may not be changed without our prior approval. You confirm that all information supplied during registration and throughout the lifetime of your account is true, correct and up‑to‑date. You agree to promptly inform us of any changes in the information you have provided, such as address, email or phone number, by updating your profile or contacting customer support.

Each Player is permitted to open only one account with Mostbet. Duplicate accounts, whether opened intentionally or by mistake, are strictly prohibited and may lead to closure of all such accounts, voiding of bets, and confiscation of bonuses and winnings. An account must be used solely by the registered Player and for personal entertainment purposes only; account sharing, transfers, or use by third parties are not allowed. You are fully responsible for maintaining the confidentiality of your login credentials and for any activity carried out through your account, whether authorised by you or not. If you suspect that your credentials have been compromised or that any unauthorised access has occurred, you must immediately change your password and contact customer support.

Mostbet reserves the right to refuse registration, to close an account, or to restrict access to certain services at our sole discretion, subject to applicable law. We may also impose additional verification or information requirements before allowing you to participate in some games, promotions or payment transactions. Inactive accounts, defined as accounts with no login activity for a continuous period which may be specified on the site, may be subject to administrative procedures such as closure or dormancy fees, in accordance with applicable policies and regulations. These measures are also part of our efforts to prevent fraud, money‑laundering and misuse of our services.

Deposits & Withdrawals

To play for real money, you must deposit funds into your Mostbet Player Account using one of the available payment methods. Details of the accepted deposit and withdrawal methods, including minimum and maximum amounts, processing times and possible fees, are provided on the Payments page of the website and summarised in the table below. You acknowledge that some payment methods may not be accessible in your jurisdiction and that the availability of methods may change over time due to commercial or regulatory reasons. All deposits must be made from payment instruments held in your own name; deposits from third parties, including family members, friends, business partners, or any other person, are not permitted. We may carry out additional checks to verify that you are the legitimate holder of the payment method used; failure to pass such checks may result in reversal of deposits and closure of your account.

Funds deposited into your Mostbet account will usually be credited within the timeframe indicated for each payment method, but actual processing times may vary due to factors beyond our control, such as payment provider delays or technical issues. Deposited funds should be used for participation in games or betting and not for currency exchange, money transfer or other non‑gaming purposes. We reserve the right to investigate and cancel deposits or withdrawals that appear to be associated with fraudulent activity, chargebacks, abuse of promotions, or violations of anti‑money laundering and counter‑terrorist financing laws. Before processing any withdrawal, we may require you to complete identity verification (KYC), including submission of documents, as detailed later in these Terms. Withdrawals will, where possible, be processed via the same payment method used for the corresponding deposit, or in accordance with our internal risk and compliance procedures.

You may request withdrawals of your real‑money balance (excluding any amounts subject to active bonus wagering requirements) at any time, provided that all conditions stated in these Terms have been fulfilled. Withdrawal requests are processed within the indicative timeframes listed on the website, but delays may occur due to additional security checks, verification of documents, or technical issues with payment providers. We are not responsible for delays caused by third‑party payment institutions or intermediary banks. We may set and modify maximum withdrawal limits per transaction, per day, per week or per month, and such limits will be indicated on the site or in your account area. In case of suspected breach of these Terms, including fraud or money‑laundering, we may withhold withdrawals and freeze your balance pending investigation by our internal team or competent authorities.

Payment Methods Table

The above table is illustrative and does not represent an exhaustive or final list of payment options at Mostbet. Availability, limits, and timescales may vary depending on your country of residence, your chosen currency, and the specific payment provider policies. To obtain the most up‑to‑date and accurate information, you must always consult the Payments or Cashier section of the Mostbet website or app. You agree that we are not liable for any losses arising from exchange rate fluctuations, payment provider errors, or additional fees charged by third parties. Where currency conversion is required, it will be carried out by the relevant payment provider or financial institution at their prevailing exchange rate, and we cannot influence or control this rate.

Bonuses & Promotions

Mostbet may offer various bonuses, free spins, free bets, loyalty rewards, tournaments and other promotional offers from time to time. Each bonus or promotion is governed by these general Terms and by specific rules described in the relevant promotional materials, including but not limited to eligibility criteria, wagering requirements, time limits, game restrictions, and maximum winnings caps. By accepting a bonus or participating in a promotion, you agree to be bound by all applicable rules. You must always read the full bonus terms carefully before opting in; failure to understand or comply with such rules may result in cancellation of the bonus and forfeiture of associated winnings. Some bonuses may be automatically credited, while others require an explicit opt‑in or bonus code at the time of deposit.

Unless stated otherwise, bonuses are intended solely for entertainment use and may not be used for abusive practices such as low‑risk betting, arbitrage, or intentional attempts to exploit loopholes in game rules or promotional mechanics. We reserve the right, in our sole discretion, to exclude certain Players from receiving bonuses, to limit the availability of promotions in specific jurisdictions, or to withdraw any promotion at any time, provided that such actions do not adversely affect rights already accrued by Players who have complied with the terms. If we identify a pattern of behaviour that we reasonably deem to constitute bonus abuse—such as creation of multiple accounts, collusion with other Players, using VPN or proxy to bypass bonus restrictions, or betting strategies aimed at artificially meeting wagering requirements—we may withhold, cancel or reclaim bonus funds and any associated winnings. We may also close or permanently ban your account in severe cases.

The order in which different balances (cash and bonus funds) are used when placing bets or playing Slots and other games is specified in the bonus rules for each promotion. Typically, real‑money funds are wagered before bonus funds, but specific structures may vary. Wagering requirements must be completed within the time limit stated in the promotion; uncompleted bonuses will be forfeited when the period expires, along with any winnings generated from the bonus unless we decide otherwise. You can usually monitor the status and progress of your active bonuses in your account dashboard and through promotional pages such as Mostbet Bonuses. However, it is your responsibility to ensure that you meet all conditions before requesting a withdrawal, as pending wagering obligations may cause partial or full cancellation of bonus balances.

Game Rules

All games offered by Mostbet, including Casino games, Slots, live dealer games, table games and mini‑games, are governed by the rules shown within each individual game interface. By participating in any game, you confirm that you have read and understood the rules and payout tables applicable to that game. The minimum and maximum stakes, return‑to‑player (RTP) values, and specific game mechanics such as paylines, bonus features, jackpots or multipliers may differ from game to game and are determined by the game provider. It is your responsibility to familiarise yourself with these parameters before placing real‑money bets. Bets that have been placed and confirmed cannot usually be cancelled or reversed unless there is a clear technical error or malfunction.

Mostbet may add, modify, suspend or remove any games from its offering at any time, for reasons such as provider decisions, regulatory requirements, or technical maintenance. If a game becomes unavailable while a round is in progress, the relevant bet may be voided or settled according to the rules of the provider and any applicable regulations. In the event of a mismatch between the information shown on our website and the information held by the game provider, the latter will generally prevail, and we reserve the right to adjust your account balance accordingly. We may also apply specific rules to progressive jackpot games, including eligibility requirements, contribution percentages and payout procedures; details will be shown in the relevant game information sections. You agree that our records of game rounds, bets, wins and losses, based on data from certified systems, are final and binding in the absence of manifest error.

You must not attempt to manipulate the outcome of games through any means, including but not limited to software tools, bots, scripts, or exploiting bugs or design flaws. Collusion with other Players, discussing private game information at live dealer tables, or using unjustified betting patterns designed to circumvent game rules is strictly prohibited and will be treated as fraud or unfair play. If we suspect or identify such behaviour, we may void your bets, cancel winnings, freeze your balance and close your account, and we may notify relevant game providers and authorities. Our goal is to maintain a fair and transparent gaming environment for all Players, and we will enforce these rules rigorously in the interest of honest participants.

Fair Play & RNG

Mostbet is committed to providing a fair, transparent and unbiased gaming experience in all Casino, Slots and other virtual games. The outcomes of such games are determined by certified Random Number Generator (RNG) systems provided by reputable game suppliers, which ensure that every spin, card draw or dice roll is random and independent of previous results. These RNG systems are regularly tested and audited by independent testing laboratories, in accordance with industry standards and applicable licensing requirements. The return‑to‑player (RTP) percentages and payout structures are embedded within each game and cannot be altered in favour of either the Player or the casino once the game has been certified. You acknowledge that while the RNG ensures fairness over the long term, short‑term play outcomes may vary significantly due to the inherent nature of chance.

We do not permit any form of manipulation of game results, including interference with the RNG or with communication between the game server and the user device. Any technical malfunction, system error, or failure of communication that affects the outcome of a game round will render that round void according to the game provider’s policies, and any affected bets may be cancelled and stakes refunded. Records maintained in our transaction logs and by our game providers are considered authoritative for the purpose of resolving disputes about game results. We do not take into account so‑called “systems”, “strategies”, or betting patterns that claim to influence random outcomes, and we strongly advise Players against relying on such methods. Gambling is a form of entertainment based on randomness, and no external method can reliably change the mathematical structure of the games.

If you believe that a game has not operated fairly or that the results do not correspond to the displayed rules or paytable, you must immediately cease playing that game and contact customer support with a detailed description and, if possible, screenshots of the problem. We will review your complaint in cooperation with the relevant game provider and provide a response within a reasonable timeframe, as further described in the Complaints section of these Terms. During the investigation, we may temporarily suspend the game in question to prevent further potential issues. However, we cannot guarantee compensation for losses if the investigation confirms that the game functioned correctly and according to its certified parameters.

Responsible Gambling

Mostbet recognises that while online gambling can be an enjoyable form of entertainment, it also carries the risk of addiction and financial harm, especially for vulnerable individuals. Our responsible gambling policy aims to provide tools, information and support so that you can maintain control over your play and make informed decisions. We strongly recommend that you treat gambling as a leisure activity, not as a source of income or a way to solve financial problems. You should only gamble with money you can afford to lose and should set sensible budgets and time limits before you start playing. If at any point you feel that gambling is starting to affect your finances, work, studies, relationships or mental health, you should stop playing and seek assistance immediately.

Mostbet offers a range of responsible gambling tools that you can use to manage your activity, including deposit limits, loss limits, session reminders, time‑outs (cooling‑off periods) and self‑exclusion. These tools are available in your account settings or upon request to customer support, and they may be adjusted based on your personal circumstances, with some changes taking effect immediately and others only after a cooling period. In addition, our systems may monitor gameplay and transactional patterns for indicators of potential problem gambling, in which case we may proactively reach out to you, apply temporary restrictions, or encourage you to use our tools. While we employ such measures in good faith, they cannot replace your own responsibility to use the services sensibly.

We pay particular attention to protecting young people from the risks associated with gambling. Under no circumstances may persons under 18 years of age use the services of Mostbet, and we will take all reasonable steps to detect and prevent underage gambling. Studies show that early exposure to gambling can significantly increase the likelihood of developing problem gambling behaviour later in life, with consequences such as debt, illegal borrowing, academic failure, and mental health issues. Parents and guardians should keep login details secure, use parental control software, and monitor internet use on shared devices to ensure that minors do not gain access to gambling sites. If you suspect that a minor is using our services, you must inform us immediately so that we can take appropriate action.

Tools & Features (table)

You should choose the tools that best match your needs and apply them before problems arise. Increasing or removing certain limits may be subject to a waiting period, in order to prevent impulsive decisions under the influence of emotions or losses. Once self‑exclusion has been applied, it cannot be revoked until the selected period expires; upon expiry, you may request reactivation, but we may require additional confirmation that you understand the risks. We also reserve the right to impose limits or self‑exclusion on your account if our monitoring indicates high‑risk behaviour, even if you do not request such measures yourself.

Support Resources

Mostbet encourages Players who experience difficulties controlling their gambling to seek professional help and support as early as possible. If you feel that you are losing control, you should immediately stop gambling and consider self‑exclusion and other tools described above. You may also contact our customer support, who can provide information and non‑therapeutic guidance about the responsible gambling measures available on the platform. However, our staff are not trained therapists, and we therefore recommend that you contact specialised support organisations that deal with problem gambling.

You may consider reaching out to independent organisations such as GamCare, Gambling Therapy, Gamblers Anonymous, and other nationally recognised counselling and support services in your country of residence. These organisations can offer confidential advice, self‑assessment tests, group meetings, online chats, and resources for both problem gamblers and their families. Many of these services are free of charge or available at low cost, and they provide support tailored to individual needs and cultural context. Additional information, including links to such organisations, may be available in the responsible gaming section of the Mostbet website.

If you are based in Poland or accessing the site from Poland, you should also familiarise yourself with any local public or private support initiatives dedicated to gambling addiction and mental health. We encourage you to seek help as soon as you notice signs of distress, such as chasing losses, hiding gambling from family members, borrowing money to gamble, or neglecting work or studies due to gaming. Early intervention significantly increases the chances of recovery and of restoring healthy control over both finances and personal life.

Prohibited Activities

When using the services of Mostbet, you must not engage in any fraudulent, unlawful, abusive or otherwise prohibited behaviour. Prohibited activities include, but are not limited to, creating or attempting to create multiple accounts, impersonating another person or providing fake documents, depositing or withdrawing funds on behalf of third parties, or attempting to launder money or finance terrorism using the platform. The use of software bots, automated scripts, or any other tools that provide an unfair advantage or manipulate gameplay is strictly forbidden. Collusion with other Players, sharing of hole‑card information at live tables, or coordinating bets to influence outcomes or share confidential game information is also prohibited.

You must not use VPNs, proxy servers or other methods to conceal your true location in order to bypass geographic restrictions or to access Mostbet from jurisdictions where online gambling is restricted or prohibited. Any attempt to exploit system vulnerabilities, bugs or configuration errors—such as trying to place bets after an event has started or at incorrect odds, or manipulating bonus mechanics—is considered system abuse and may result in serious sanctions. Harassment, abusive language, spam or threats directed at customer support staff or other Players via chat functions are not tolerated and may lead to restricted access or closure of your account. Chargebacks or reversals of deposits without valid justification are treated as a violation of these Terms and may be reported to payment providers and credit agencies.

If we reasonably believe that you have engaged in any prohibited activity, we may, at our sole discretion, freeze your account, suspend access to our services, cancel bets, confiscate winnings and recover any bonuses credited to you. We may also request additional documents, conduct enhanced due diligence, and share relevant information with law enforcement agencies, regulators or other online casinos and sportsbooks if permitted by law. Our decision regarding breaches of these Terms will be final and binding, subject to your right to escalate a complaint under the Complaints and Dispute Resolution section.

Restricted Countries (table)

Mostbet may not be legally allowed to offer its services in certain countries or territories due to local regulations or licensing conditions. It is strictly prohibited to use the services of Mostbet from any jurisdiction in which online gambling is illegal or restricted. The list below provides examples of countries that are typically restricted; it is not exhaustive and may change over time. You are solely responsible for ensuring that your use of our services is lawful in your country or region of residence. If you access Mostbet from a restricted jurisdiction, your account may be immediately closed, and any bets placed may be voided.

This table is illustrative only and may not reflect all restrictions applicable at a given time. Mostbet reserves the right to block registrations and access from any country or territory where it is unlawful or commercially unfeasible to offer services. If we discover that you have circumvented our geolocation controls or used technological means to disguise your location, we may void your bets, confiscate your winnings, and close your account. We may also share information about such conduct with relevant authorities if required by law.

Privacy & Data Protection

Mostbet is committed to protecting your privacy and handling your personal data in a lawful, fair and transparent manner. The collection and processing of your personal information are governed by our Privacy Policy, which forms an integral part of these Terms. When you register an account, make deposits or withdrawals, participate in games, or communicate with us, we may collect personal data such as your name, contact details, identification documents, transaction history, device information, IP address, and gaming activity. This data is used for purposes including account management, payment processing, verification, responsible gambling monitoring, security, and compliance with anti‑money laundering and other regulatory obligations.

We may share your personal data with carefully selected third parties, such as payment service providers, identity verification services, analytics providers, game suppliers, and regulatory or law enforcement authorities where required. Such sharing will be limited to what is necessary for the fulfilment of contractual obligations or legal requirements. We implement appropriate technical and organisational measures to protect your data against unauthorised access, alteration, loss or destruction, such as encryption, access controls, and regular security audits. However, no system can provide absolute security, and you acknowledge that the transmission of information via the internet always carries some risk.

As a user, you may have certain rights under applicable data‑protection laws, such as the right to access your data, to correct inaccuracies, to request deletion or restriction of processing, to object to certain types of processing, and to withdraw consent where processing is based on consent. You may also have the right to data portability and to lodge a complaint with a supervisory authority if you believe that your rights have been violated. To exercise your rights, you should contact us using the contact details indicated in the Privacy Policy or on the website. We will respond to such requests within the time limits and conditions set by law and may require proof of identity to ensure that we process requests only for the correct account holder.

Mostbet uses cookies and similar technologies on its website and mobile applications to improve functionality, tailor the user experience, remember preferences, analyse traffic and carry out marketing activities. By using our services, you consent to the use of cookies in accordance with our Cookie Policy. You can manage your cookie preferences through your browser settings or via on‑site tools, but disabling certain types of cookies may affect the performance of the site or your ability to use some features. International transfers of personal data outside your country of residence may occur where necessary for the operation of the services, and in such cases we will ensure an adequate level of protection as required by applicable laws.

Account Suspension & Termination

Mostbet reserves the right to suspend, restrict or close your account at any time, subject to applicable legal requirements, if we have reason to believe that you have breached these Terms, engaged in prohibited activities, or posed a risk to the integrity or reputation of our services. Suspension may involve temporarily blocking your ability to deposit, withdraw, or participate in games, while we investigate unusual activity or suspected violations. During suspension, we may request additional documentation or clarification from you; failure to cooperate may result in closure of your account. If the investigation confirms a serious violation, we may terminate your account, void bets, confiscate bonuses and winnings, and return remaining deposits where legally required.

You have the right to request closure of your account at any time by contacting customer support or using available account‑closure tools on the website, if provided. Before closing the account, we may require you to withdraw your remaining real‑money balance, subject to verification procedures. Once closed, your account cannot be re‑opened automatically; you may be required to submit a new registration request, which we reserve the right to accept or decline at our sole discretion. Closure of an account does not relieve you of any obligations incurred prior to the date of closure, such as unpaid debts, chargebacks, or legal responsibilities.

Accounts that remain inactive for an extended period, as defined in the applicable policy displayed on the site, may be designated as dormant or closed. We may attempt to contact you before applying dormancy fees or closure, using the latest contact details registered in your account. Any balance in a dormant account will be handled in accordance with applicable regulations, which may include transfer to a designated fund, escheatment to authority, or other legally prescribed processes. You are responsible for keeping your contact information up‑to‑date to ensure you receive relevant notices.

Limitation of Liability

Mostbet provides its services on an “as is” and “as available” basis, without any warranties or representations of any kind, whether express or implied, to the maximum extent permitted by law. We do not warrant that the services will be uninterrupted, error‑free, or free of viruses or other harmful components, nor do we guarantee that defects will be corrected in a specific timeframe. While we take reasonable steps to provide a stable and secure platform, technical issues, maintenance, or failures of third‑party systems (such as internet service providers, payment gateways or game servers) may occasionally affect availability. You acknowledge that gambling involves inherent risk of financial loss and that you are solely responsible for any losses incurred while using the services.

To the maximum extent permitted by applicable law, Mostbet, its affiliates, directors, employees, and service providers shall not be liable for any indirect, incidental, consequential, special or punitive damages, including loss of profits, data, goodwill or other intangible losses arising out of or in connection with your use of the services, even if we have been advised of the possibility of such damages. Our total aggregate liability to you for any claim relating to these Terms or the services shall be limited to the lesser of (i) the amount of your net deposits made in the 30 days preceding the event giving rise to the claim, or (ii) the amount required by mandatory 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 legally be excluded.

You agree to indemnify and hold harmless Mostbet, its affiliates, officers, employees and agents from and against any and all claims, demands, liabilities, damages, losses, costs and expenses, including reasonable legal fees, arising out of or in connection with your breach of these Terms, your violation of any law or third‑party rights, or your use of the services. This indemnity obligation will survive the termination of your account and your cessation of use of the services.

Complaints & Dispute Resolution

If you have a complaint concerning Mostbet’s services, including issues related to game outcomes, account management, payments, bonuses or alleged violations of these Terms, you should first contact our customer support team via the channels indicated on the website, providing full details of your complaint. You must submit your complaint as soon as reasonably possible after the event giving rise to it, and in any case within the time limits indicated in our policies on the site, if any. Please include your account details, the date and time of the incident, the game or transaction involved, and any supporting evidence such as screenshots or transaction records. We will acknowledge receipt of your complaint and endeavour to investigate and respond within a reasonable timeframe.

Our support team will review your complaint in good faith, in cooperation with relevant internal departments and, where necessary, with external partners such as game providers or payment processors. If your complaint relates to a game result, we may rely on logs and data from the game provider’s systems, which are considered authoritative unless there is clear evidence of malfunction. We will provide you with a clear explanation of our findings and any decision made. If you are not satisfied with the outcome of your initial complaint, you may request that it be escalated to a higher level of management or compliance staff, in which case additional review may be carried out.

Where applicable law or licensing regulations provide for an independent Alternative Dispute Resolution (ADR) body or other external mechanism, we may inform you of such options and how to access them. However, the availability and nature of ADR may depend on your jurisdiction and on the specific operator and licensing framework governing Mostbet at the time. In all cases, we will comply with any binding decisions or orders from competent courts or regulatory authorities.

Governing Law

These Terms, and any dispute or claim arising out of or in connection with them or their subject matter, shall be governed by and construed in accordance with the laws of the jurisdiction in which the operator of Mostbet is incorporated or licensed, unless mandatory provisions of the laws of your country of residence apply. The choice of governing law does not affect your statutory consumer rights, if any, under the laws of your country of residence that cannot be excluded by agreement. In the event of any conflict between versions of these Terms in different languages, the English version applicable to Poland shall prevail to the extent permitted by law.

You irrevocably agree that the courts of the governing jurisdiction shall have non‑exclusive jurisdiction to settle any dispute or claim arising out of or in connection with these Terms or your use of the services. This means that we retain the right to bring proceedings against you in any other court of competent jurisdiction if we deem it necessary to protect our legitimate interests, such as in cases of fraud, debt collection or intellectual property infringement. You should familiarise yourself with the legal implications of participating in online gambling under both the governing law and the law of your country of residence.

Final Provisions

These Terms, together with the Privacy Policy, Cookie Policy, game rules, bonus rules and any other documents expressly incorporated by reference, constitute the entire agreement between you and Mostbet with respect to the use of the services and supersede all prior agreements, understandings or arrangements between us, whether written or oral. If any provision of these Terms is found to be invalid, illegal or unenforceable by a competent court or authority, that provision shall be modified to the minimum extent necessary to make it valid and enforceable, and the remaining provisions shall remain in full force and effect. Our failure to enforce any provision of these Terms at any time shall not be construed as a waiver of our right to enforce that or any other provision at a later date.

We may assign, transfer or subcontract our rights and obligations under these Terms, in whole or in part, to another entity or affiliate, provided that such assignment does not adversely affect your rights under applicable law. You may not assign or transfer your rights or obligations under these Terms to any third party. We may communicate with you via email, on‑site messages, SMS or other electronic means, using the contact details held in your account; it is your responsibility to ensure that such details remain accurate and up‑to‑date. For general information about our services and promotional offers, you may also consult the homepage Mostbet, where you will find current content, links and updates.

By registering, maintaining an account and using the services of Mostbet, you acknowledge that you have read these Terms in full, understand them, and agree to be bound by them. You also confirm that you are at least 18 years old, that you are legally permitted to participate in online gambling in your jurisdiction, and that you accept full responsibility for your actions on the platform. If you do not accept these Terms, you must not use the services and must immediately close your account if you already have one.
