b399 Frequently Asked
Questions

Creating a b399 account takes under two minutes. Visit the b399 Login page, click the registration option, and fill in your username, email address, mobile number, and a secure password. You must be at least 18 years old and a resident of Bangladesh to register. Once submitted, you will receive a verification code via SMS to confirm your mobile number.

b399 requires a valid government-issued photo ID to complete KYC (Know Your Customer) verification. Accepted documents include your Bangladesh National Identity Card (NID), a valid Bangladeshi passport, or a driver's licence issued by the Bangladesh Road Transport Authority (BRTA). Upload clear, unobstructed photos of both sides of your document through the Account Settings panel.

b399 completes most account verifications within 24 hours of document submission. During peak periods — such as Eid or major cricket tournaments — it may take up to 48 hours. You will receive an email notification once your account is verified. Until verification is complete, deposit and withdrawal limits may be restricted.

To reset your b399 password, go to the Login page and click 'Forgot Password'. Enter the email address registered to your account and b399 will send a password reset link within a few minutes. If you do not receive the email, check your spam folder. If the issue persists, contact [email protected] with your registered mobile number for manual assistance.

No. b399 strictly permits one account per person. Registering multiple accounts is a violation of the Terms and Conditions and may result in all accounts being permanently suspended and any balances forfeited. If you have accidentally created a duplicate account, contact [email protected] immediately to resolve the situation before it leads to a suspension.

To close your b399 account, go to Account Settings and select the account closure option, or email [email protected] with the subject line 'Account Closure Request'. Any remaining balance will be returned to your verified payment method within five business days. If you are closing your account due to gambling concerns, b399 recommends using the self-exclusion tool instead, which offers more structured protection.

b399 offers betting on a wide range of sports with a strong focus on cricket, including BPL (Bangladesh Premier League), IPL, ICC T20 World Cup, Test matches, and Bangladesh Tigers fixtures. Other available sports include football (domestic and international leagues), kabaddi, field hockey, tennis, and basketball. Cricket markets are the most extensive, covering match winner, top batsman, total runs, and over-by-over live betting.

b399 live betting on BPL matches allows you to place bets during the match in real time as odds update ball-by-ball. Markets available in-play include match winner, next wicket method, runs in the next over, and player performance markets. Bets are accepted up until the ball is bowled — once the bowler begins their run-up, the market is temporarily suspended. All live odds reflect the current game state and are recalculated after each delivery.

Yes. All slot games on b399 are provided by certified third-party studios including Pragmatic Play, NetEnt, Microgaming, and Spribe. Every game uses a certified Random Number Generator (RNG) that has been independently audited to ensure fair, unpredictable outcomes on every spin. b399 does not modify the RNG or alter the Return to Player (RTP) percentages set by the game providers.

Yes. b399 is fully optimised for mobile play. The platform works smoothly in any modern mobile browser on Android or iOS without requiring a separate app download. All games — including slots, live casino tables, and sports betting — are available on mobile. For the best experience, use a stable internet connection (Wi-Fi or 4G) and keep your browser updated to the latest version.

The Return to Player (RTP) percentage varies by game and is set by the individual game provider, not by b399. Most slots available on b399 have RTPs between 95% and 97%, which is in line with industry standards. The RTP for each specific game is displayed in the game's information panel before you start playing. A higher RTP means a lower house edge over a large number of spins.

b399 operates as a secure entertainment platform using 256-bit SSL encryption to protect all account data and financial transactions. Player funds are held separately from operational funds, and all payments are processed through established, regulated payment providers including bKash, Nagad, and major Bangladeshi banks. b399 does not share your personal data with third parties for marketing purposes without your explicit consent.

The minimum age to register and play on b399 is 18 years old. This is a strict requirement with no exceptions. b399 verifies the age of all players during the KYC process using government-issued identification. Any account found to be held by a person under 18 will be immediately closed and any winnings forfeited. b399 strongly encourages parents and guardians to use parental control tools on shared devices.

You can set daily, weekly, or monthly deposit limits on b399 by navigating to Account Settings and selecting the Responsible Gaming section.

You can also contact [email protected] to set limits on your behalf.

To self-exclude from b399, go to Account Settings, select Responsible Gaming, and choose Self-Exclusion, or email [email protected] with the subject line 'Self-Exclusion Request'. Self-exclusion periods range from 6 months to permanent. During exclusion your account is suspended, your balance is returned, and you are removed from all marketing communications. Self-exclusion takes effect within 24 hours and cannot be reversed during the minimum exclusion period.

Yes. b399 provides a session time limit tool in the Responsible Gaming section of your Account Settings. You can set a maximum session duration of between 30 minutes and 8 hours. Once the limit is reached, you will be logged out automatically and will not be able to log back in for a configurable cool-down period. This tool is designed to help you stay in control of the time you spend on the platform each day.

If you believe gambling is negatively affecting your finances, relationships, or mental health, act immediately — do not wait for things to escalate. Contact b399 support at [email protected] to activate self-exclusion and have your account suspended. You can also speak confidentially with a trained gambling support counsellor through international helplines such as the National Problem Gambling Helpline (1-800-522-4700). b399 is committed to supporting responsible gaming and will never pressure you to continue playing.
