Account & Registration

Creating a 3666bit account is straightforward and takes under two minutes. Go to the registration page, enter your mobile number, choose a strong password, and confirm your details. Once you submit the form, your account is active immediately — no waiting for email verification. You can log in and make your first deposit right away.

Yes. You must be at least 18 years old to register and play on 3666bit. This is a firm requirement and applies to all players regardless of location. 3666bit takes responsible gaming seriously and does not allow underage players on the platform. If we find that an account belongs to someone under 18, it will be closed immediately and any funds returned.

No. Each player is allowed one account only. Creating multiple accounts is against the 3666bit terms and conditions and can result in all accounts being suspended and balances forfeited. If you've forgotten your login details, use the password reset option rather than creating a new account.

On the login page, tap "Forgot Password" and enter the mobile number linked to your account. You'll receive a verification code by SMS. Enter the code, then set a new password. The whole process takes about a minute. If you don't receive the SMS, check that you're entering the correct number and try again after a few minutes.

Basic account verification is completed during registration using your mobile number. For higher withdrawal limits, 3666bit may ask you to verify your identity by submitting a copy of your NID (National Identity Card) or passport. This is a standard process to protect your account and comply with platform security requirements. Verification documents can be submitted through the account settings section.
Deposits & Withdrawals

3666bit supports bKash and Nagad — the two most widely used mobile payment services in Bangladesh. Both are available for deposits and withdrawals. You don't need a bank account to fund your 3666bit account; your bKash or Nagad wallet is all you need.

Deposits via bKash and Nagad are processed quickly — most deposits reflect in your 3666bit account within a few minutes. If your deposit hasn't appeared after 10 minutes, check that the transaction was completed successfully in your bKash or Nagad app. If the payment went through but your balance hasn't updated, contact 3666bit support with your transaction reference number.

Go to the withdrawal section in your account, enter the amount you want to withdraw, and select bKash or Nagad as your payout method. Make sure the mobile number on your payment wallet matches the one registered on your 3666bit account. Withdrawals are typically processed within 1–24 hours depending on the time of day. Larger withdrawals may require additional verification before they are approved.

Yes. 3666bit has minimum deposit and withdrawal thresholds to keep transactions manageable. The exact minimums are displayed on the deposit and withdrawal pages inside your account. These amounts are kept low so that players with smaller budgets can still participate without needing to commit large sums upfront.

Withdrawals can be delayed or rejected for a few reasons:
  • Your account identity has not been fully verified
  • The mobile number on your payment wallet doesn't match your 3666bit account
  • An active bonus has wagering requirements that haven't been met yet
  • The withdrawal amount exceeds your current daily limit
If none of these apply and your withdrawal is still stuck, reach out to the 3666bit support team via live chat with your transaction details.
Games & Betting

3666bit offers a wide range of games including Aviator (crash game), Teen Patti (live card game), Mega Fishing, Super Wheel, Shaolin Soccer, and a full live sports betting section covering cricket, football, kabaddi, and more. The full game library is available on both the website and the Android app. Visit the Game page for the complete list.

Yes. All 3666bit games use a certified Random Number Generator (RNG) system. Game outcomes are generated independently and cannot be manipulated by the platform or any third party. The provably fair system allows players to verify the result of any round themselves. For a detailed explanation of how the technology works, visit the Game Technology page.

Aviator is a crash-style game where a multiplier starts at 1x and increases as a plane climbs. You place your bet before the round starts, then cash out at any point while the plane is still flying. If you cash out before the plane flies away, you win your bet multiplied by the value at the time you cashed out. If the plane flies away before you cash out, you lose your bet. Rounds are short — usually under 30 seconds — making it one of the fastest games on the platform. Learn more on the Aviator page.

Yes. The Live section on 3666bit lets you bet on matches while they are in progress. Odds update in real time based on what's happening in the game. Cricket is particularly well covered, with ball-by-ball markets available on major matches. Football, kabaddi, and other popular sports are also available in the live betting section.

Teen Patti is a traditional South Asian card game played with three cards. On 3666bit, you play against a live dealer with real cards streamed in real time. The rules follow the classic format — you can play blind or seen, and the goal is to have a better hand than the dealer. The live format means you're playing alongside other real players, which gives it the social feel the game is known for. Visit the Teen Patti page for full details.
Android App

The 3666bit app is an Android APK that you download directly from the website — it is not available on the Google Play Store. Visit the App page, tap the download button, and the APK file will download to your phone. Before installing, go to your phone's Settings and enable "Install from unknown sources" (or "Allow from this source" on newer Android versions). Then open the downloaded file and follow the installation steps. The app is around 18 MB and installs in under a minute.

Currently, the 3666bit app is only available for Android devices. iPhone users can access the full platform through the mobile browser on their device — the website is fully optimised for mobile and works well on Safari and Chrome on iOS. All games, deposits, withdrawals, and account features are available through the browser version.

The most common reason is that "Install from unknown sources" is not enabled on your device. To fix this:
  • Go to Settings on your Android phone
  • Search for "Install unknown apps" or "Special app access"
  • Find your file manager or browser and toggle the permission on
  • Try opening the APK file again
If the problem persists, make sure you have enough storage space and that the APK file downloaded completely without interruption.

The 3666bit app is optimised for Bangladesh's mobile network conditions and is designed to use data efficiently. Crash games and card games use minimal data per session. Live betting and live dealer games use slightly more due to real-time streaming, but the app is built to work well even on standard 4G connections. You can also play most games on a stable 3G connection without major issues.
Security & Responsible Gaming

Yes. 3666bit uses SSL encryption to protect all data transmitted between your device and the platform. Your personal details, payment information, and account activity are stored securely and are never shared with third parties without your consent. For full details on how your data is handled, read the Privacy Policy.

3666bit provides several tools to help you stay in control of your gaming:
  • Deposit limits — set a daily, weekly, or monthly cap on how much you can deposit
  • Session time reminders — get notified when you've been playing for a set amount of time
  • Self-exclusion — temporarily or permanently close your account if you need a break
  • Reality checks — periodic pop-ups showing how long you've been playing and your net result
All of these tools are available in the responsible gaming section of your account. Visit the Responsible Gaming page for more information.

If you want to take a break or stop playing entirely, you can request a self-exclusion through your account settings or by contacting the 3666bit support team directly via live chat. You can choose a temporary exclusion period (e.g. 30 days, 90 days) or a permanent closure. During a self-exclusion period, you will not be able to log in or make deposits. Any remaining balance will be returned to you after the exclusion period ends, or immediately in the case of permanent closure.
