All questions about account registration

All you need to register on 3377 is an active Bangladeshi mobile number and a strong password. You can optionally add an email address — it'll come in handy for password recovery later. You must be at least 18 years old. No documents or photo uploads are required — the whole process takes under 2 minutes.

No, only one account is allowed per mobile number. Any attempt to create a second account with the same number will be automatically blocked by the system. Creating multiple accounts violates 3377's terms and may result in both accounts being suspended.

Once registration is complete, you can log in and browse the site right away. To place bets, you'll need to make a deposit first. Deposit a minimum of 100 BDT via bKash or Nagad and jump straight into Sports Betting or Live Casino.

First, make sure your mobile number is correct and your network is active. Wait 1 minute, then click "Resend". If the OTP still doesn't arrive, restart your phone and try again. If the issue persists, contact support@3377.bio with your mobile number and the team will verify it manually.

Yes. Under 3377's responsible gaming policy, no one under 18 may create an account. You'll need to confirm your age during registration. If there's any doubt, we may request a copy of your national ID or passport.

No, a referral code is not mandatory. However, if a friend has given you one, enter it at registration — both you and your friend will receive a special bonus. Referral codes cannot be added or changed after registration.

For security reasons, your registered mobile number cannot be changed directly. To request a change, email support@3377.bio with the required identity verification documents. The support team will verify your identity and complete the process within 48 hours.

3377 is primarily designed for users in Bangladesh. If you're accessing from outside the country, you can use a VPN, but an active Bangladeshi mobile banking account is still required for payments. Contact support if you run into any issues.
Login
All questions about logging in

3377 offers three login methods: (1) mobile number and password, (2) email and password, or (3) OTP — just enter your mobile number and log in with the OTP you receive. The mobile app also supports fingerprint and Face ID.

On the login page, click the "Forgot Password?" link. Enter your registered mobile number and you'll receive an OTP. Verify with the OTP, then set a new password. The whole process takes under 2 minutes.

Entering the wrong password 5 times in a row will lock your account for 30 minutes. Wait 30 minutes and try again, or log in using the OTP method. Contact support if you need urgent access.

Using "Remember Me" on your personal device is safe. Do not use this option on shared or public computers. Biometric login on the mobile app is an even more secure alternative.

You can be logged in on multiple devices under the same account simultaneously. View your active sessions from the dashboard and end any unfamiliar session directly from there.

For security, your session will automatically end after 30 minutes of inactivity. Enabling "Remember Me" extends this timeout. With biometrics turned on in the mobile app, you can log back in instantly.
Payments, Deposits & Withdrawals
All questions about deposits & withdrawals

You can deposit at 3377 via bKash, Nagad, and Rocket. Bank transfers and cryptocurrency are also supported in certain cases. The fastest methods are bKash and Nagad — your balance is credited instantly.

The minimum deposit is just ৳100. The maximum per transaction depends on your payment method — bKash and Nagad generally allow up to ৳25,000 per transaction. For larger amounts, split across multiple transactions or use a bank transfer.

Deposits are usually reflected instantly. If not, refresh the page and wait 5 minutes. If the issue persists, send your transaction ID and screenshot to support@3377.bio. Our team will resolve it within 30 minutes.

Withdrawals on 3377 are typically processed within 15–30 minutes. bKash and Nagad are the fastest options — in most cases, funds arrive within 10 minutes. Bank transfers may take 1–2 business days. Slight delays are possible during peak hours.

3377 does not charge any withdrawal fees. However, your mobile banking provider (bKash, Nagad, etc.) may apply their own cash-out charges. These fees are outside 3377's control.

The minimum withdrawal is 500 BDT. The standard daily withdrawal limit is 1 lakh BDT. VIP members enjoy higher limits. For larger withdrawals, please contact support.

Common reasons for withdrawal rejection include: unmet bonus wagering requirements, incomplete account verification, or a payment number that doesn't match the one used at registration. If you're unsure what the issue is, contact us at support@3377.bio.

3377 charges no deposit fees — every BDT you send goes straight to your balance. Note that bKash or Nagad send money fees may apply, as these are determined by the payment provider's own policy.

Contact us at support@3377.bio as soon as possible with the transaction ID, amount, and date. Recovering funds sent to a wrong number can be difficult, so always double-check the number before sending.

Yes, withdrawals at 3377 are available 24/7. However, mobile banking systems may have their own processing windows at night, which can occasionally cause minor delays.
Bonuses & Offers
Questions about bonuses, cashback & promotions

A welcome bonus is automatically added on your first deposit after registration. Deposit a minimum of ৳500 and get up to 100% bonus. No promo code needed — just make your first deposit and the bonus will be credited to your wallet automatically.

The wagering requirement is the number of times you must bet your bonus amount before you can withdraw it. For example, a 5x wagering requirement on a ৳1,000 bonus means you must place a total of ৳5,000 in bets before withdrawing. Requirements vary by bonus.

Yes, 3377 offers daily reload bonuses, cashback offers, and loyalty points. You earn loyalty points every time you log in. Visit the rewards page to see all active offers.

Yes, most bonuses have an expiry period — typically 7 to 30 days. If the wagering requirements aren't met within that time, the bonus balance will be forfeited. Make sure to read the terms carefully as soon as you receive a bonus.

Share your unique referral code. When a friend registers using your code and makes their first deposit, you'll earn a referral bonus. The more friends you refer, the more you earn. Bonus amounts may vary based on current promotions.

Yes, there is an option to decline a bonus at the time of deposit. Many experienced bettors choose to skip bonuses to avoid wagering requirements, allowing them to withdraw freely. The choice is entirely yours.

Free bets will appear automatically in your betting slip once credited. Select the "Use Free Bet" option when placing your bet. If your free bet wins, only the profit is withdrawable — the original stake amount is not.

Weekly cashback is calculated every Monday and credited to your wallet by Tuesday. The amount is based on your net losses from the previous week. VIP members receive cashback at a higher rate.
Betting Rules
Betting & Gaming Questions

At 3377, you can bet on cricket, football, tennis, badminton, kabaddi, hockey, and many more sports. Live Casino, slots, poker, and virtual sports are also available. Visit the Match Odds page to see all ongoing events.

Yes, 3377 offers in-play and live betting. Place bets as the match unfolds with real-time odds updates. Live match scores and statistics are also available all in one view.

In some cases, you can settle a bet before the match ends using the "Cash Out" feature. Cash Out is not available on all bets — when it is, you will see it on the betting slip. Bets generally cannot be cancelled once a match has started.

If a match is cancelled or abandoned, the stake for that bet is refunded. For accumulator bets, the cancelled event is removed and the odds are recalculated based on the remaining selections.

The minimum bet is just ৳10. The maximum varies by event and market type — typically ranging from ৳50,000 to ৳200,000. VIP members may have higher limits.

An accumulator (or parlay) bet combines multiple events into one. If every selection wins, the odds multiply for a potentially huge payout. However, if even one selection loses, the entire bet is lost. You need at least 2 events to place an accumulator.

Once a match ends and the result is confirmed, winnings are automatically credited to your wallet. Settlement is usually completed within 5–15 minutes of the final whistle. For Live Betting, it's often even faster.

3377 uses decimal odds. For example, odds of 2.5 mean a BDT 100 bet returns BDT 250 if you win (your BDT 100 stake plus BDT 150 profit). The higher the odds, the lower the chance of winning — but the bigger the reward.

In handicap betting, the weaker team is given a virtual goal or run advantage. For example, Bangladesh +1.5 goals means 1.5 goals are added to their match result. This levels the playing field and makes betting more balanced and engaging.

Log in to your account and go to the "My Bets" or "Betting History" section. There you can see full details of all active, settled, and cancelled bets. You can filter by date, event, amount, and result.
