Learn about the terms of using the 399o platform, account policies, betting rules, and your rights and responsibilities. Reading and complying with these Terms and Conditions is mandatory for all 399o users.

Last updated: October 2026 | These Terms and Conditions apply to all 399o users

1. Introduction and Acceptance

Welcome to the 399o online betting and casino platform. These Terms and Conditions govern all rules, rights, and responsibilities that apply to your use of the 399o platform and that both you and 399o are required to follow. By accessing the platform through the 399o website, mobile application, or any other channel, you fully agree to these Terms and Conditions. Please read them carefully and in full, as they contain important information about your legal rights and obligations.

The 399o platform operates under internationally recognised gaming licences and regulations. We are committed to providing a safe, fair, and responsible gaming environment. 399o reserves the right to amend, revise, or update these Terms and Conditions at any time. Such changes take effect immediately upon publication on the website. It is your responsibility to review these Terms and Conditions regularly for any updates. Continued use of the 399o platform after any changes constitutes your acceptance of the revised terms.

399o provides services for entertainment purposes only and exclusively for individuals aged 18 or over who are legally permitted to participate in online gaming. By using 399o, you confirm that you are of legal age and that you have the legal right to engage in online betting and gaming under the laws of your country or region. If online gaming is prohibited in your country, you may not use the 399o platform.

Important Notice

Before using the 399o platform, verify the online gaming laws applicable in your country or region. Users who access 399o from jurisdictions where online betting is prohibited do so entirely at their own risk.

2. Account Registration and Eligibility

2.1 Age and Legal Eligibility

To open an account and place bets on 399o, you must be at least 18 years of age, or the legal age of majority in your country, whichever is higher. 399o strictly prohibits minors from using the platform and conducts regular age verification checks. If 399o suspects that an account is being operated by someone under 18, we will suspend that account immediately and void all winnings.

To verify your age and identity, 399o may request documents from you at any time, such as a national ID, passport, birth certificate, or driving licence. You are required to submit these documents to complete the verification process. Your withdrawals may be held until verification is complete. 399o is committed to responsible gaming and the protection of minors, and we enforce this policy strictly.

2.2 Account Information and Security

When registering on 399o, you must provide accurate, complete, and up-to-date information. Your name, date of birth, address, email, and phone number must be real and belong to you. Providing false or misleading information is a violation of 399o Terms and Conditions and may result in account closure and forfeiture of all balances. If any of your personal details change, you must update them on the 399o platform immediately.

Each person may open only one 399o account. Creating multiple accounts is strictly prohibited, and if 399o detects that an individual is operating more than one account, all duplicate accounts will be closed and all associated bets, winnings, and bonuses will be voided. The security of your account is your own responsibility. Keep your username and password confidential and never share them with anyone. You are fully responsible for all activity that takes place on your account.

Tips: Account Security

Use a strong password containing letters, numbers, and special characters. Change your password regularly and enable two-factor authentication for extra security.

2.3 Account Verification (KYC)

399o complies with international KYC (Know Your Customer) and AML (Anti-Money Laundering) regulations. As part of this, we may request proof of identity, proof of address, and payment method verification from you at any time. Submitting these documents is mandatory, and failure to do so may result in your account being restricted or closed. Full KYC verification must be completed before your first withdrawal from the 399o platform.

The verification process is typically completed within 24-72 hours of document submission. 399o reserves the right to request additional verification on any account if suspicious activity is detected or as part of a routine review. All information and documents you provide are kept secure in accordance with the 399o privacy policy and are used solely for verification and security purposes.

3. Betting Rules and Conditions

3.1 Betting Process and Acceptance

Your account must have sufficient balance to place bets on 399o. All bets are final and confirmed once the 399o system accepts the bet and you receive a confirmation message in your account. Once a bet is placed and confirmed, it cannot be cancelled, changed, or withdrawn except in cases specifically outlined in the 399o Terms and Conditions. It is your responsibility to review your bet slip before placing, as 399o will not be liable for any errors.

399o reserves the right to reject or accept any bet without providing a reason. In certain situations, such as technical errors, obvious pricing mistakes, or suspicious betting patterns, 399o may void a bet and refund the stake. All bets and betting markets are subject to 399o betting rules and sport-specific rules available on the platform. If an event is cancelled, postponed, or altered, bets will be settled in accordance with 399o rules.

3.2 Maximum and Minimum Betting Limits

399o sets specific minimum and maximum bet limits for each game, sport, and market. These limits may vary depending on the event, league, and market, and are displayed on the bet slip at the time of placement. 399o reserves the right to change these limits at any time without prior notice. If a bet exceeds the set limits, it will either be rejected or settled at the maximum permitted amount.

399o may apply individual betting limits to certain accounts in specific circumstances. This can occur if 399o suspects unusual betting activity, identifies responsible gaming concerns, or has other regulatory reasons for doing so. You can also set your own betting limits in your account settings as part of responsible gaming, and 399o will honour those personal limits.

3.3 Odds and Payouts

399o offers competitive odds across all sports and gaming markets. Odds are displayed in decimal format on your bet slip and represent the potential return on your stake. Odds on 399o may change in real time based on market demand, event developments, and other factors. The odds confirmed at the moment your bet is placed will apply to that bet, regardless of any subsequent changes.

All winnings are settled to your account as soon as the bet result is confirmed. 399o settles all bets in accordance with official results announced after the conclusion of each event. In the event of a dispute or incorrect result, 399o will make the final determination based on official sources and applicable rules. Maximum payout limits may apply to certain bets and markets, and this information is available in the betting rules.

4. Payment and Withdrawal Policy

4.1 Deposit Methods and Process

399o supports a range of secure and convenient payment methods for players in Bangladesh, including mobile banking, bank transfer, credit/debit cards, and other electronic wallets. Each payment method may have its own minimum and maximum deposit limits, which are displayed on the deposit page. Most deposits are processed instantly and your account balance is updated within minutes.

399o does not charge deposit fees, though some payment providers may apply their own transaction fees. It is your responsibility to ensure that the payment method you use is registered in your name and funded with your own money. Third-party payments are strictly prohibited, and 399o reserves the right to investigate any suspicious transactions and suspend accounts accordingly. If you experience any issues making a deposit, contact 399o customer support immediately.

4.2 Withdrawal Process and Requirements

To withdraw funds from the 399o platform, you must complete full KYC verification and have a fully verified account. The minimum withdrawal amount is BDT 500, and the maximum withdrawal limit depends on your account level and payment method. Withdrawal requests are typically processed within 24-72 hours after verification and security checks are completed. In some cases, additional verification may be required, which can extend the processing time.

399o recommends withdrawing via the same payment method you used to deposit, as this is required for AML compliance. If your deposit method is not available for withdrawals, you may need to verify an alternative method. 399o does not charge withdrawal fees, though payment providers may apply their own. You can track your withdrawal status in your account dashboard. If your withdrawal is delayed or you experience any issues, contact customer support.

4.3 Wagering Requirements

If you accept a bonus or promotional offer, wagering requirements may apply to your deposit and bonus funds. Wagering requirements mean you must place a specified amount in bets before the bonus and any associated winnings can be withdrawn. Each bonus has its own wagering conditions, which are clearly stated in the bonus terms. Standard wagering requirements on 399o are generally between 3x and 5x the bonus amount, depending on the type of promotion.

Only real-money bets placed on eligible games and markets will count toward wagering requirements. Certain games or bet types may be excluded or may contribute only partially. You can check your wagering progress in your bonus section. Attempting to withdraw before wagering requirements are met will result in the bonus and associated winnings being voided. 399o displays all bonus terms transparently and recommends that you read the full terms and conditions before accepting any offer.

5. Bonus and Promotion Terms

5.1 Bonus Eligibility and Claims

399o regularly provides a variety of bonuses and promotional offers for new and existing players, including welcome bonuses, reload bonuses, cashback offers, and more. Each bonus has specific eligibility criteria and terms that must be met in order to claim and use it. Bonuses are generally available to verified accounts only and may be claimed once per person, household, or IP address.

To claim a bonus, you may need to opt in on the promotions page or at the time of deposit. Some bonuses are credited to your account automatically once eligibility is met, while others must be claimed manually. 399o reserves the right to refuse, cancel, or amend any bonus at any time with or without notice. Bonus abuse is strictly prohibited and may result in forfeiture of the bonus and account suspension.

5.2 Bonus Validity and Expiry

All 399o bonuses have a set validity period within which the bonus must be used and wagering requirements completed. Standard bonus validity ranges from 7 to 30 days from the date of issue, depending on the specific promotion. If the bonus and wagering requirements are not completed before expiry, the bonus balance and all associated winnings will be automatically voided and removed from your account.

399o recommends that players regularly check the bonus section for active bonuses and their expiry dates so no offer goes to waste. Expired bonuses cannot be recovered or reactivated. If you are unsure about your bonus expiry or have any questions, contact the 399o customer support team, who can assist you with all bonus-related matters.

5.3 Bonus Abuse and Fraud

399o takes bonus abuse very seriously and maintains a strict anti-fraud policy. Examples of bonus abuse include: creating multiple accounts to claim the same bonus more than once, syndicate betting, arbitrage betting, low-risk or no-risk betting patterns used solely to complete wagering requirements, and any other activity that attempts to exploit the bonus system. 399o uses advanced fraud detection systems to identify suspicious activity.

If 399o detects bonus abuse or fraudulent activity, we will immediately void all bonuses and associated winnings, suspend or close all related accounts, and forfeit any remaining balance. 399o reserves the right to pursue legal action in serious fraud cases and may share information with other operators and regulatory authorities. Use bonuses responsibly and comply with the terms and conditions of every promotion.

6. User Responsibilities

6.1 Responsible Gaming

399o believes in responsible gaming and is committed to player protection. Online betting and gaming should be for entertainment purposes only and should never be treated as a source of income. It is your responsibility to ensure you only bet what you can afford to lose, and that gaming never has a negative impact on your personal life, family, or finances. 399o provides various tools and resources to help you stay in control of your gaming activity.

You can set deposit limits, betting limits, loss limits, and session time limits on your account to help you manage your spending and time. 399o also offers self-exclusion and time-out options if you feel you need a break. If you or someone you know is showing signs of problem gambling, please seek help from a professional organisation. The 399o customer support team is always available to guide you on responsible gaming tools and resources.

6.2 Legal Compliance

By using the 399o platform, you confirm and warrant that you are complying with all applicable local, national, and international laws and regulations regarding online gaming and betting in your area. It is your responsibility to verify the laws of your own country or jurisdiction and to ensure that using 399o is legal where you are. 399o will not be held liable if you access the service from a jurisdiction where it is prohibited or restricted.

You are required to comply with all tax and reporting obligations applicable in your jurisdiction regarding your winnings and gaming activity. 399o does not withhold tax on your winnings, but it is your responsibility to declare and pay any applicable taxes to your local tax authority. You must use 399o only for lawful and legitimate purposes and must never engage in money laundering, fraud, or any other illegal activity.

6.3 Personal Information Updates

It is your responsibility to ensure that all personal information on your 399o account is accurate, complete, and up to date at all times. If any of your personal details change, such as your name, address, contact information, or payment method, you must update this information in your account settings immediately. Outdated or incorrect information may cause issues with payment processing, verification, and account access.

If you fail to update your personal information and this results in any problems or losses, 399o will not be held liable. Keeping your contact details up to date is especially important, as 399o uses this information to reach you regarding important account updates, promotions, and security matters. If you have trouble updating your information or need assistance, please contact customer support.

7. Prohibited Activities

7.1 Fraudulent and Illegal Activities

Any fraudulent, illegal, or dishonest activity on the 399o platform is strictly prohibited. This includes, but is not limited to: money laundering or other financial crimes, hacking or attempting to compromise 399o systems, use of cheating software or bots, collusion or coordination with other players, use of insider information, use of false or stolen identities, and chargeback fraud. 399o employs advanced security and fraud detection systems to identify and prevent such activity.

If 399o detects any prohibited activity, we will immediately suspend or permanently close the associated account, void all bets, forfeit all winnings and bonuses, and report to law enforcement agencies and regulatory bodies where necessary. 399o cooperates fully with authorities in any investigation and may share information as required. Individuals involved in fraudulent activity will be liable for legal consequences, and 399o reserves the right to seek compensation.

7.2 Multiple Accounts and Collusion

Each person is permitted to open only one 399o account. Creating or operating multiple accounts is strictly prohibited and constitutes a breach of these Terms and Conditions. This applies to opening accounts using different email addresses or phone numbers for the same person, multiple accounts held by members of the same household at the same IP address or physical address, and any other situation where 399o suspects the same person or connected individuals are exploiting the system. 399o uses various methods to detect duplicate accounts.

Collusion occurs when two or more players work together to gain an unfair advantage against 399o or other players. This can include sharing information, coordinated betting, or other tactics that compromise the fairness of the game. 399o has a zero-tolerance policy on collusion and multiple accounts. If such activity is detected, all associated accounts will be permanently closed and all funds will be forfeited.

7.3 Use of Software and Bots

The use of any automated software, bots, scripts, spiders, crawlers, or other tools on the 399o platform that access the platform, collect data, place bets, or perform any other activity without direct human input is strictly prohibited. 399o permits only manual, direct human interaction, and the use of automated systems violates our fair play policy. This includes betting bots, casino bots, value betting software, and other automated tools.

399o actively monitors platform activity and can quickly detect the use of bots or automated software. If such activity is identified, the account will be suspended immediately, all bets cancelled, and all funds may be forfeited. 399o may implement technical measures to block bot access and may pursue legal action in serious cases. All players should use only the official 399o website and app and should never trust third-party software.

8. Account Suspension and Closure

8.1 Suspension by 399o

399o reserves the right to suspend or restrict any account at any time if we suspect or believe that a breach of terms has occurred, fraudulent activity has taken place, abuse has been detected, or for other security or regulatory reasons. During a suspension, you will not be able to access your account, place bets, or make deposits or withdrawals. 399o will notify you of the reason for the suspension and may request additional information or documents as part of the investigation.

A suspension may be temporary, pending the outcome of an investigation, or permanent if a violation is confirmed. If the investigation concludes that no violation occurred, your account will be reactivated and all funds returned. If a violation is confirmed, however, 399o may permanently close the account and forfeit all or part of the balance. 399o handles all suspensions and investigations fairly and transparently.

8.2 Self-Exclusion and Self-Closure

399o provides self-exclusion and self-closure options for players who feel they need a break from gaming. You can request a temporary or permanent account closure at any time through customer support. Self-exclusion periods range from 24 hours to 6 months or longer, depending on your preference. During the exclusion period, you will not be able to access your account or receive any promotional communications from 399o.

Permanent self-closure means your account will be closed for good and cannot be reopened. If you set up self-exclusion, you may withdraw your remaining balance before the exclusion takes effect or afterward through Customer Support. 399o fully respects all self-exclusion requests, and no account will be reopened before the exclusion period ends. Responsible gaming is our priority, and we encourage players to use these tools whenever needed.

8.3 Inactive Accounts and Dormancy Fees

If your 399o account is inactive for 12 consecutive months (no logins, bets, or transactions), it will be classified as a dormant account. 399o will email you before your account becomes dormant to give you the opportunity to reactivate it. If you do not respond and the account remains inactive, 399o may charge a small monthly dormancy fee (up to BDT 500 per month) to cover account maintenance costs. This fee will be deducted from your remaining balance for as long as a balance exists.

You can reactivate a dormant account at any time by logging in and making a deposit or placing a bet. Once reactivated, the dormancy fee will stop being charged. If your dormant account has a remaining balance, you can withdraw it at any time through customer support after completing KYC verification. 399o recommends that players check their accounts regularly to avoid dormancy. If you no longer wish to use 399o, withdraw your balance and submit a request to close your account.
