3999 Bit accepts deposits and withdrawals via the three most popular mobile banking services in Bangladesh:

• bKash — instant deposits and withdrawals
• Nagad — instant deposits and withdrawals
• Rocket — deposits and withdrawals within minutes

All transactions are processed in BDT with no currency conversion fees.

The minimum deposit at 3999 Bit is ৳100. There is no maximum deposit limit for standard accounts, though very large deposits may require additional verification. Your deposit is credited to your account balance instantly after the transaction is confirmed by your mobile banking provider.

Most withdrawals are processed within 5 to 15 minutes during normal operating hours. During peak periods or for larger amounts, processing may take up to one hour. Withdrawals are sent directly to the bKash, Nagad or Rocket number registered on your account. The minimum withdrawal amount is ৳200.

First, check your bKash, Nagad or Rocket transaction history to confirm the payment was sent successfully. If the transaction shows as completed on your mobile banking app but your 3999 Bit balance has not updated after 10 minutes, contact live chat support and share your transaction ID. The support team can trace the payment and credit your account manually if needed.

For security reasons, withdrawals are sent to the mobile banking number registered on your 3999 Bit account. If you need to change your withdrawal number, contact support with proof of ownership of the new number. This policy protects your funds from being redirected by unauthorised parties.

New players at 3999 Bit receive a welcome bonus on their first deposit. The bonus is applied automatically when you make your first deposit — no promo code required. The exact bonus amount and percentage may vary depending on current promotions. Log in after registering to see the current welcome offer in your account dashboard.

A wagering requirement means you need to bet a certain multiple of your bonus amount before you can withdraw bonus-derived winnings. For example, a 10x wagering requirement on a ৳500 bonus means you need to place ৳5,000 in total bets before the bonus converts to withdrawable cash. The specific wagering requirement for each promotion is shown in the promotion details inside your account.

Yes. Most 3999 Bit bonuses have an expiry period, typically 7 to 30 days from the date the bonus is credited. If the wagering requirement is not completed within the expiry period, the bonus and any bonus-derived winnings are removed from your account. The expiry date for each active bonus is shown in your account's Bonus section.

Yes. 3999 Bit runs regular promotions for existing players including reload bonuses, fishing game tournaments, free spin drops on new slot releases and live casino cashback offers. Check the Promotions section in your account after logging in to see what is currently active. Promotions are updated regularly, so it is worth checking back frequently.

Fishing games like Jackpot Fishing and Fierce Fishing work by letting you aim and shoot at fish swimming across the screen. Each fish has a different point value and some carry special bonuses or jackpot triggers. You choose your weapon (which determines your bet per shot) and fire. The more powerful the weapon, the higher the cost per shot but also the higher the potential payout. Catching rare or boss fish triggers the biggest rewards.

RTP stands for Return to Player. It is the percentage of all wagered money that a game pays back to players over a very large number of rounds. For example, a 97% RTP means that for every ৳100 bet across all players, ৳97 is returned as winnings on average. This is a long-term statistical figure — your individual session results will vary. All 3999 Bit games publish their RTP figures. You can find them on the Game page.

All games on 3999 Bit use a certified Random Number Generator (RNG) that is independently tested and verified. The RNG ensures that every spin, every fish spawn and every card dealt is completely random and cannot be predicted or manipulated. RTP figures are audited regularly. 3999 Bit publishes these figures openly so players can make informed decisions about which games to play.

Minimum bets vary by game. Most slot-style games and fishing games start from ৳10 to ৳50 per round. Live casino tables generally start at ৳100 per hand or spin. The exact minimum and maximum bet for each game is shown on the game screen before you start playing. Visit the Game page for a full overview of available titles.

Yes. The Live Casino at 3999 Bit is fully optimised for mobile. The HD video stream is compressed for mobile connections so it runs smoothly on 4G without excessive data usage. The interface adapts to portrait and landscape orientations. For the best experience, use the 3999 Bit Android app or a modern mobile browser with a stable internet connection.

The 3999 Bit app is available as a free Android APK download from the App page. It is not listed on the Google Play Store, so you need to allow installation from unknown sources in your Android settings before installing. Go to Settings → Security → Unknown Sources and toggle it on. Then download the APK from the App page and tap the file to install. The process takes about 30 seconds.

The most common reason for installation failure is that "Install from Unknown Sources" is not enabled. Go to your phone's Settings → Security (or Privacy on some devices) and enable Unknown Sources or allow your browser/file manager to install apps. If you still get an error, try these steps:

• Delete the downloaded APK file and re-download it from the App page.
• Make sure you have at least 100MB of free storage space.
• Restart your phone and try installing again.
• If the issue persists, contact live chat support with your phone model and Android version.

If a game disconnects or crashes during an active round, the round result is recorded on the server. When you reconnect and reopen the game, it will resume from where it left off or show the result of the interrupted round. If you believe a bet was lost due to a technical error rather than a game result, contact support with the approximate time of the issue and the game name — the team can review server logs and resolve it.

Currently, the dedicated 3999 Bit app is available for Android only. iPhone and iPad users can access the full platform through the mobile browser at 3999-bit.net. The browser version is fully optimised for iOS Safari and supports all games, deposits, withdrawals and account management without needing an app. An iOS app may be available in the future — check the App page for updates.

3999 Bit uses SSL encryption on all pages and API connections, meaning your data is encrypted in transit. Passwords are stored using one-way hashing — even 3999 Bit staff cannot see your password. Suspicious login attempts trigger automatic alerts. You can also enable two-factor authentication (2FA) from your account security settings for an extra layer of protection. See the Privacy Policy for full details on data handling.

Change your password immediately from the Login page using the "Forgot Password" option. Then contact live chat support and report the suspected unauthorised access. The support team can review your account's login history, freeze the account temporarily if needed and help you secure it. Never share your password or OTP codes with anyone — 3999 Bit staff will never ask for your password.

Log in to your account and go to Responsible Gaming settings. From there you can:

• Set daily, weekly or monthly deposit limits.
• Enable a session time reminder that alerts you after a set period.
• Request a cooling-off period (24 hours to 30 days).
• Apply for self-exclusion for longer periods including permanent exclusion.

These tools take effect immediately. For more information, visit the Responsible Gaming page.

3999 Bit does not sell or share your personal data with third-party marketers. Data may be shared with payment processors (bKash, Nagad, Rocket) solely for the purpose of processing your transactions, and with fraud prevention services as required. Full details are in the Privacy Policy. You can request a copy of your data or ask for your account to be deleted by contacting support.
