11kk App FAQ —
Everything You Need to Know

You must be at least 18 years old to register and play on the 11kk app. This applies to all games — Blackjack, Mine, Bingo, Boat of Fortune, and Badminton betting. If we find that an account belongs to someone under 18, the account will be closed and any balance returned. Please play responsibly. Visit our Responsible Gaming page for more information.

No. Each player is allowed one account only. Creating multiple accounts to claim bonuses more than once is against our Terms and Conditions and will result in all accounts being suspended and balances forfeited. If you've forgotten your login details, use the password reset option on the Login page rather than creating a new account.

Go to the Login page and tap "Forgot Password". Enter the mobile number linked to your account and you'll receive an OTP. Enter the OTP, set a new password, and you're back in. The whole process takes about 60 seconds. If you no longer have access to the phone number on your account, contact support at [email protected] with your account details and we'll help you recover access.

You can request account closure at any time by emailing [email protected]. Before closing, make sure you withdraw any remaining balance. If you're closing your account because of concerns about your gaming habits, we strongly recommend using the self-exclusion tool first — visit our Responsible Gaming page to set limits or take a break without permanently closing your account.

11kk accepts deposits via bKash, Nagad, and Rocket — the three most widely used mobile banking services in Bangladesh. All transactions are processed in BDT (Bangladeshi Taka) so there's no currency conversion involved. Simply go to the Finance / Wallet section, select your preferred method, enter the amount, and follow the on-screen steps. Your balance updates within seconds of a successful transfer.

The minimum deposit on 11kk is ৳100 BDT. There is no maximum deposit limit for standard accounts, though very large deposits may require additional verification. We recommend starting with a small deposit to get familiar with the platform before increasing your stake. All deposit amounts are shown clearly in the Finance / Wallet section before you confirm.

Deposits via bKash, Nagad, and Rocket are processed instantly in most cases. Your 11kk balance should update within 30 seconds of a successful mobile banking transfer. If your balance hasn't updated after five minutes, check that the transaction was completed on your mobile banking app and that you used the correct 11kk payment reference. If the issue persists, contact support with your transaction ID and we'll resolve it quickly.

11kk does not charge any fees on deposits. The full amount you send via bKash, Nagad, or Rocket is credited to your gaming balance. Note that your mobile banking provider may apply their own standard transaction charges — these are outside 11kk's control. Check your bKash, Nagad, or Rocket app for their current fee schedule if you're unsure.

Go to the Finance / Wallet section and select "Withdraw". Choose your preferred method — bKash, Nagad, or Rocket — enter the amount you want to withdraw, and confirm. The funds will be sent to the mobile banking account linked to your 11kk profile. Make sure the mobile number on your 11kk account matches the number registered with your mobile banking service to avoid delays.

Most 11kk withdrawals are processed within 15 to 30 minutes. During peak hours or for larger amounts, processing can take up to a few hours. We aim to complete all withdrawal requests within 24 hours at the absolute latest. If your withdrawal hasn't arrived after 24 hours, contact support with your withdrawal reference number and we'll investigate immediately.

The minimum withdrawal amount on 11kk is ৳200 BDT. This applies to all payment methods. There is no maximum withdrawal limit for verified accounts. If you haven't completed any identity verification and your withdrawal request is above a certain threshold, you may be asked to provide a copy of your national ID. This is a standard process to protect your account and comply with financial regulations.

Withdrawals can be declined for a few reasons: your account may have an unmet bonus wagering requirement, the mobile number on your 11kk account doesn't match your bKash/Nagad/Rocket account, or your account may need identity verification. Check the notification in your 11kk wallet for the specific reason. If you're unsure, contact support and we'll explain exactly what's needed to release your funds.

The 11kk app currently offers five games: Blackjack, Mine, Bingo, Boat of Fortune, and Badminton sports betting. Each game is built specifically for mobile play on Android devices and optimised for Bangladesh's 4G networks. New games are in development — register now to get notified when new titles are added. Visit the Game page for a full overview.

Yes. All 11kk game outcomes are generated by a certified Random Number Generator (RNG). This means every card dealt in Blackjack, every tile in Mine, every ball in Bingo, and every spin in Boat of Fortune is completely random and cannot be predicted or manipulated — not by the platform, not by other players, and not by any third party. The RNG is independently tested and certified. You can view the game rules and fairness information inside each game before you place a bet.

Some 11kk games offer a demo or practice mode that lets you try the game mechanics without risking real BDT. This is a great way to understand how Mine's multiplier system works or to get comfortable with Blackjack strategy before playing for real. Check inside each individual game for the demo option. Note that demo play winnings cannot be withdrawn — only real-money play generates withdrawable winnings.

In the 11kk Mine game, you're presented with a grid of tiles. Hidden beneath some tiles are mines — the rest are safe. You pick tiles one at a time. Each safe tile you reveal increases your multiplier. You can cash out at any point to collect your winnings. If you hit a mine, the round ends and you lose your stake. The more mines you set at the start, the higher the potential multiplier — but the greater the risk. It's a pure strategy game that rewards careful decision-making.

The 11kk Badminton section lets you bet on real badminton matches with live odds updated in real time. Select a match, choose your outcome (e.g. which player wins), set your BDT stake, and confirm your bet. If your prediction is correct, your winnings are credited to your wallet automatically after the match ends. Odds reflect the current probability of each outcome and change as the match progresses. All bets are settled in BDT.

New players who register through the 11kk app receive a welcome bonus on their first deposit. The exact bonus amount and terms are listed on the Current Offers page — we update promotions regularly so it's worth checking before you deposit. The welcome bonus is credited automatically once your first deposit clears. No bonus code is required.

A wagering requirement means you need to bet a certain multiple of your bonus amount before you can withdraw the bonus as cash. For example, a ৳500 bonus with a 10x wagering requirement means you need to place ৳5,000 in total bets before the bonus converts to withdrawable cash. The specific wagering requirement for each 11kk promotion is clearly stated on the Current Offers page. We keep our terms straightforward — no hidden conditions.

Yes. 11kk runs regular reload bonuses, game-specific promotions, and seasonal offers for existing players. Blackjack cashback, Mine multiplier boosts, and Bingo free card offers are among the promotions that run throughout the year. The best way to stay updated is to check the Current Offers page regularly and make sure push notifications are enabled in the 11kk app so you never miss a deal.

Bonuses are usually credited within a few minutes of the qualifying action (e.g. completing your first deposit). If your bonus hasn't appeared after 15 minutes, check that you met all the qualifying conditions listed on the Current Offers page — minimum deposit amount, eligible payment method, and any other requirements. If everything looks correct and the bonus still hasn't appeared, contact support with your account details and we'll sort it out.

Visit the App page on this website and tap the download button to get the 11kk APK file for Android. Because the app is distributed directly rather than through the Google Play Store, you'll need to allow installation from unknown sources in your Android settings. Go to Settings → Security → Unknown Sources and enable it, then open the downloaded APK to install. The process takes about 60 seconds on most Android devices. The 11kk app is not available on iOS at this time.

The 11kk app runs on Android 6.0 and above. This covers the vast majority of Android phones currently in use across Bangladesh, including popular mid-range models from Samsung, Xiaomi, Realme, and Tecno. If your phone is running Android 5 or older, we recommend using the mobile browser version of 11kk instead — it works on any modern browser including Chrome and Firefox.

Yes. All 11kk games are fully playable through the mobile browser on your phone — no download required. Just visit 11kk-app.app in Chrome or any modern browser, register or log in, and start playing. The browser version works well on 4G connections. That said, the 11kk app offers a faster, smoother experience with shorter load times and push notifications for bonuses, so we recommend downloading it when you get the chance.

First, check your internet connection — the 11kk app works best on a stable 4G or Wi-Fi connection. If your connection is fine, try closing other apps running in the background to free up RAM. You can also try clearing the 11kk app cache in your Android settings (Settings → Apps → 11kk → Storage → Clear Cache). If the problem continues after these steps, uninstall and reinstall the latest version from the App page. Still having issues? Contact support and we'll help diagnose the problem.
