399b Frequently Asked Questions

Creating a 399b account takes less than three minutes — visit the site, click the registration button, and fill in your full name, date of birth, email address, mobile number, and a secure password. You will need to confirm that you are aged 21 or older and agree to the platform terms before your account is activated. Once registered, you can complete identity verification to unlock full deposit and withdrawal access.

399b requires a government-issued photo ID for identity verification — accepted documents include your National Identity Card (NID), passport, or driving licence. You may also be asked to submit a recent utility bill or bank statement as proof of address. Uploads are reviewed by the verification team typically within 24 hours. Completing KYC is mandatory before processing your first withdrawal and is a standard industry requirement to protect all members.

The minimum age to register and play on 399b is 21 years old. This is a strict, non-negotiable requirement enforced through identity verification during the registration process. Any account found to belong to a person under 21 will be suspended immediately and all funds returned. 399b takes its 21+ policy seriously to promote responsible gaming across Bangladesh.

You can reset your 399b password directly from the login page by clicking "Forgot Password" and entering your registered email address or mobile number. A secure reset link or OTP will be sent to you within a few minutes. If you do not receive the reset email, check your spam folder or contact 399b support via live chat at [email protected]. For account security, always choose a strong, unique password and avoid reusing credentials from other platforms.

Yes — 399b gives you full control over your account status. You can request a temporary suspension (time-out) of 24 hours up to 6 weeks, or a permanent self-exclusion, by contacting the support team via live chat or emailing [email protected]. Temporary suspensions can also be self-activated in account settings under the Responsible Gaming section. If you close your account permanently, any remaining balance will be refunded to your verified payment method after standard processing.

bKash deposits on 399b are typically credited to your account within 1 to 5 minutes of a successful transaction. During peak periods — such as BPL match days or major promotions — processing may occasionally take up to 15 minutes. If your deposit has not appeared after 30 minutes, save your bKash transaction ID and contact 399b support via live chat so the team can trace and credit the transaction manually. Always double-check the deposit reference before confirming.

The minimum deposit on 399b is ৳200 BDT. This low entry point makes 399b accessible to players across all budgets, from casual cricket bettors to regular slots players. The minimum applies across all supported payment methods including bKash, Nagad, Rocket, Upay, and bank card options. There is no maximum cap on deposits, though very large deposits may be subject to enhanced verification for security purposes.

The minimum withdrawal on 399b is ৳500 BDT. Withdrawal requests submitted to mobile wallets such as bKash, Nagad, and Rocket are typically processed within 1 to 4 hours during business hours (BST UTC+6). Bank transfers to Dutch-Bangla Bank, BRAC Bank, Islami Bank, City Bank, or Sonali Bank may take 1 to 3 business days depending on the receiving bank. Your account must have completed KYC verification before any withdrawal can be processed.

399b does not charge any platform-side fees on standard deposits or withdrawals. However, your payment provider — such as bKash, Nagad, or your bank — may apply their own standard transaction charges, which are outside 399b's control. We recommend checking your mobile wallet's fee schedule before initiating transactions. For large withdrawals processed via bank transfer, your bank may levy an inward remittance fee; this is not charged by 399b.

399b supports a wide range of payment methods tailored to Bangladeshi players. Mobile wallets include bKash, Nagad, Rocket, and Upay. Bank transfers are accepted from Dutch-Bangla Bank, BRAC Bank, Islami Bank, City Bank, and Sonali Bank, among others. Card payments via Visa and Mastercard are also supported. All transactions are processed in Bangladeshi Taka (BDT), so there are no currency conversion charges for local players.

399b offers an extensive range of cricket betting markets covering international and domestic competitions. You can bet on match winners, series outcomes, top run-scorers, top wicket-takers, over/under totals, and ball-by-ball live betting on BPL (Bangladesh Premier League), IPL, T20 World Cup, ICC Test series, and Bangladesh Tigers ODI fixtures. Live in-play markets are updated in real time during matches, giving you the flexibility to respond as the game develops.

Yes — all slot games available on 399b are sourced from certified, internationally recognised game studios including Pragmatic Play, NetEnt, Microgaming, and Spribe. These providers use independently audited Random Number Generator (RNG) technology to ensure every spin outcome is genuinely random and unpredictable. Return-to-Player (RTP) percentages are displayed in each game's information panel so you can make informed choices before you play.

399b is fully optimised for mobile play — all games, betting markets, account management, and payment features are accessible directly through your smartphone's web browser without needing to download any additional app. The platform is compatible with Android and iOS devices. For the best experience, use a modern browser such as Chrome, Safari, or Firefox and ensure you have a stable internet connection, particularly when playing live casino games or live cricket betting.

399b's live casino section features real-time table games streamed from professional studios with live human dealers. Available games include Live Baccarat, Live Roulette, Live Blackjack (including Double Exposure Blackjack), Live Teen Patti, Andar Bahar, and game-show style titles such as Crazy Time and Lightning Roulette by Evolution Gaming and Ezugi. New live titles are added regularly, so the game lobby is continually expanding for 399b members.

If a cricket match is officially abandoned, cancelled, or ends without a result due to rain, bad light, or other causes before the minimum number of overs required for a valid result are completed, 399b will void all affected bets and return stakes in full to your account balance. For Duckworth-Lewis-Stern (DLS) method results, bets are settled on the official match result as declared by the relevant cricket board. Specific conditions are detailed in the 399b Sports Betting Terms.

399b offers a welcome bonus to all newly registered and verified members on their first deposit. The exact bonus percentage and maximum bonus amount are displayed on the promotions page at the time of your registration, as offers are updated regularly. To qualify, make a first deposit that meets the minimum threshold and opt in to the welcome offer during the deposit process. All welcome bonuses are subject to wagering requirements — read the full terms on the promotions page before claiming.

A wagering requirement specifies how many times you must bet the bonus amount (or bonus plus deposit, depending on the specific promotion) before the associated winnings become withdrawable cash. For example, a 20x wagering requirement on a ৳1,000 bonus means you must place ৳20,000 in qualifying bets before requesting a withdrawal of bonus-derived winnings. Different game types contribute differently — slots typically count 100%, while table games and live casino may count less. Always check the individual promotion's terms for the exact contribution rates.

Yes — 399b runs regular promotions for existing members beyond the initial welcome offer. These include reload deposit bonuses, free spins on featured slot titles, cashback on sports betting losses, and seasonal offers tied to events such as IPL, T20 World Cup, BPL, Eid, and Pohela Boishakh. Loyalty members may also receive exclusive personalised offers. Check the promotions section of your account regularly and opt in to promotional emails (with your consent) to stay up to date.

No — bonus funds and any winnings generated from bonus funds cannot be withdrawn until the applicable wagering requirements have been fully met. If you submit a withdrawal request while wagering is still in progress, the bonus and associated winnings may be forfeited, depending on the specific promotion's terms. Your real-money (non-bonus) balance can typically be withdrawn at any time subject to standard KYC and minimum withdrawal conditions. We always recommend reading the bonus terms in full before opting in.

All limit reductions take effect instantly; limit increases require a mandatory 7-day cooling-off period.

If you feel that gambling is having a negative impact on your finances, relationships, or mental wellbeing, act early — the sooner you seek support, the better the outcome. Start by activating a time-out or self-exclusion via your 399b account settings or by contacting our support team at [email protected]. You can also reach the 399b responsible gaming team via 24/7 live chat for immediate assistance. For independent professional support, contact a licensed counsellor or the National Institute of Mental Health (NIMH) in Dhaka. You are not alone, and seeking help is the right decision.
