399bit Frequently Asked Questions

Creating a 399bit account takes about two minutes. Visit 399bit.onl, tap the 399bit Login link, and follow the on-screen registration form — fill in your name, email address, mobile number, and preferred password. You must confirm that you are at least 21 years old. Once submitted, a verification email or SMS is sent to confirm your details before your account is fully activated.

399bit requires a valid government-issued photo ID for KYC verification — your National Identity Card (NID) is the most commonly accepted document in Bangladesh. Alternatively, a valid passport or driving licence is accepted. You will also need to provide a selfie holding your ID alongside a dated note. Documents are reviewed within 24 hours in most cases.

The minimum age to register and play on 399bit is 21 years old. This applies to all players in Bangladesh without exception. Age is verified during the KYC process using your National Identity Card or passport. Any account found to belong to a person under 21 is closed immediately and all deposits are refunded.

To reset your 399bit password, go to the login page and tap "Forgot Password". Enter your registered email address and a reset link will be sent to your inbox within a few minutes. Follow the link to set a new password. If you do not receive the email, check your spam folder or contact support at [email protected].

No. 399bit strictly allows one account per player, per household, and per device. Creating multiple accounts (also called duplicate accounts) is a violation of our Terms and Conditions and will result in all associated accounts being permanently closed and any balances forfeited. If you have accidentally created a duplicate, contact support immediately to resolve it.

To close your 399bit account permanently, email our support team at [email protected] from your registered email address and request account closure. Withdraw any remaining balance before making the request. Our team processes closure requests within 48 hours. If you are closing due to gambling concerns, we strongly recommend using the self-exclusion tool instead, which offers structured protection.

To deposit via bKash on 399bit, log in to your account, navigate to the Cashier or Deposit section, and select bKash as your payment method. Enter your bKash registered mobile number and the amount you wish to deposit. You will receive a prompt on your bKash app to authorise the transaction. Once confirmed, funds typically appear in your 399bit account within a few minutes.

Nagad deposits on 399bit are processed almost instantly — most transactions credit to your account balance within 1 to 5 minutes. In rare cases during peak periods, processing can take up to 15 minutes. If your deposit has not appeared after 30 minutes, contact 399bit support with your Nagad transaction reference number for a manual check.

The minimum deposit on 399bit is ৳200 BDT for most payment methods including bKash, Nagad, and Rocket. For bank transfer deposits via Dutch-Bangla Bank, BRAC Bank, City Bank, or Islami Bank, the minimum may be higher — check the Cashier section for the current limit for each method. There is no maximum deposit cap for standard players, though high-value deposits may require additional verification.

The minimum withdrawal amount on 399bit is ৳500 BDT. Withdrawals are processed to the same payment method used for the most recent deposit wherever possible. For bKash and Nagad withdrawals, funds typically arrive within 1 to 24 hours. Bank transfer withdrawals may take 1 to 3 business days. Your account must be fully KYC-verified before a withdrawal can be processed.

399bit does not charge any platform-side fees on deposits or withdrawals. However, your payment provider — bKash, Nagad, Rocket, Upay, or your bank — may apply their own transaction charges as per their standard fee schedule. 399bit has no control over third-party provider fees. Always check your payment app for any applicable service charges before initiating a transaction.

Yes, 399bit accepts deposits and withdrawals via Rocket (Dutch-Bangla Bank's mobile banking service) and Upay. Both methods work the same way as bKash — select your preferred method in the Cashier, enter your registered mobile number, and authorise the transaction from your Rocket or Upay app. Minimum amounts and processing times are the same as other mobile banking methods.

To bet on cricket at 399bit, log in, navigate to the Cricket section, and browse available matches — including BPL, IPL, T20 World Cup, Bangladesh Tigers series, and other international fixtures. Select a match, choose your market (match winner, top batsman, total runs, etc.), enter your stake in BDT, and confirm the bet. Live in-play betting is available on most major matches.

399bit offers a wide library of slot games from leading providers including Pragmatic Play, NetEnt, and Microgaming.

You can browse the full catalogue in the Slots section of the 399bit platform. All games are available on mobile and desktop browsers without any app download required.

Plinko on 399bit is a popular instant-win game where a ball is dropped from the top of a pegged board and bounces randomly to land in one of several payout slots at the bottom. Each slot carries a different multiplier. You choose your stake, select the risk level (low, medium, or high), then drop the ball and watch where it lands. Higher risk settings offer bigger multipliers but lower landing probabilities.

Dragon Fishing 2 is a multiplayer shooting fish game available on 399bit where players fire cannons at on-screen sea creatures to earn coins. Each fish species carries a different payout value — larger, rarer creatures like dragons and boss monsters pay significantly more. You control your cannon's power and bullet cost, adjusting your risk-reward balance as you play. The game runs in real time and is available directly in-browser on mobile.

All games available on 399bit from certified providers like Pragmatic Play, Evolution Gaming, NetEnt, and Microgaming use independently audited Random Number Generators (RNGs) to ensure fair outcomes. RTP (Return to Player) percentages are published by game providers and are not altered by 399bit. The platform uses SSL encryption and does not interfere with game logic. You can verify provider certifications on their respective official sites.

Yes, 399bit is fully optimised for mobile play on both Android and iOS devices. The entire platform — including cricket betting, slots, Plinko, Dragon Fishing 2, and live casino games — runs in your mobile browser without requiring any app download. The site uses a mobile-first layout designed for small screens, so navigation, betting, and cashier functions all work smoothly on a smartphone.

399bit offers a welcome bonus to new players on their first deposit. The exact bonus amount and percentage match are displayed on the promotions page and may vary by campaign period — for example, during BPL season or Eid promotions. Always read the bonus terms before claiming, paying particular attention to the wagering requirement (the number of times you must bet the bonus before withdrawing winnings derived from it).

A wagering requirement (also called a playthrough requirement) is the number of times you must bet a bonus amount before any winnings from that bonus can be withdrawn as cash. For example, a ৳1,000 bonus with a 20x wagering requirement means you must place ৳20,000 in total bets before requesting a withdrawal of bonus-derived funds. 399bit states the wagering requirement clearly on each bonus offer page.

Yes, all 399bit bonuses carry an expiry date by which the wagering requirement must be completed. The standard expiry period is 7 to 30 days from the date the bonus is credited, depending on the specific promotion. If the wagering requirement is not met within the expiry window, the bonus and any associated winnings are removed from your account. Check the individual bonus terms for the exact deadline.

399bit periodically offers free spins on selected slot titles and reload bonuses for existing players as part of seasonal promotions — for instance around Eid, Pohela Boishakh, or during major cricket tournaments like the BPL or IPL. Reload bonuses credit a percentage of your next deposit as bonus funds. Free spins winnings are subject to the same wagering terms as standard bonuses. Check the promotions section of your account for currently active offers.

Bonus funds on 399bit cannot be withdrawn directly — they must be converted to real-money winnings by completing the stated wagering requirement first. Once the playthrough is satisfied, the winnings derived from the bonus become withdrawable cash. Your account balance panel separates your real-money balance from any active bonus balance so you can track progress clearly at all times.

399bit is a safe and reliable platform that uses 256-bit SSL encryption to protect all data transmitted between your device and our servers — the same encryption standard used by online banks. Player funds are held separately from operational funds. All personal and financial data is processed in accordance with our Privacy Policy. We do not sell or share player data with unaffiliated third parties.

To self-exclude from 399bit, contact our support team at [email protected] and request a self-exclusion. You can choose a minimum 6-month exclusion, up to 5 years, or a permanent ban.

Self-exclusion is one of several responsible gaming tools available to all 399bit players at no cost.

Yes, 399bit allows all registered players to set daily, weekly, or monthly deposit limits in BDT directly from Account Settings under the Responsible Gaming section. Once a limit is set, it takes effect immediately. Reducing a limit is instant; increasing a limit requires a 7-day cooling-off period before it applies. This tool helps you manage your gambling budget proactively.
