ok77 — Crash Games, Slots
& Live Casino in Bangladesh

Go to the ok77 register page and fill in your mobile number, a password and your date of birth. You must be 18 or older. The form completes in about 30 seconds. No email address is required at sign-up — you log in with your mobile number. After registration, verify your number by entering the OTP sent to your phone. Your account is then active and ready for a first deposit.

Your first deposit earns 200% on top of what you deposit, capped at ৳27,000. If you deposit ৳500, your bonus is ৳1,000, bringing your total playing balance to ৳1,500. To withdraw the bonus portion, you must wager the total (deposit + bonus) 7 times within 7 days. So ৳1,500 × 7 = ৳10,500 in bets. After that, the bonus converts to real withdrawable cash. Full terms are at ok77 Bonus & VIP.

ok77 supports bKash, Nagad, Rocket, Upay and Bank Transfer for both deposits and withdrawals. All are processed in Taka with no currency conversion. Deposits appear within 1 minute after you submit the transaction ID. Withdrawals take an average of 43 minutes for bKash and Nagad, slightly longer for Rocket (46 min) and Upay (45 min). The minimum deposit is ৳100 and the minimum withdrawal is ৳1,200. For detailed steps, see the ok77 Deposit Guide.

ok77 accepts three documents for identity verification: National ID Card (NID), Passport or Driving Licence. You will need to upload a clear photo of the front and back. KYC review takes up to 12 hours. It is required before your first withdrawal, so uploading it immediately after registration avoids any delay when you are ready to cash out. Contact 24/7 live chat if your document upload is rejected — agents can guide you through re-submission. See the full process at ok77 Withdrawal & KYC Guide.

Standard withdrawals process in an average of 43 minutes for bKash, Nagad and Bank Transfer. Rocket takes about 46 minutes and Upay about 45 minutes. Your very first withdrawal may take up to 6 hours while the KYC team reviews your documents. After that, all subsequent withdrawals go at the normal speed. The daily withdrawal limit at Bronze VIP level is ৳50,000. Higher VIP tiers get larger limits — up to ৳3,90,000 per day at Black Diamond level.

Yes. The ok77 app is available as a free APK download — version 3.7.6, 52 MB, compatible with Android 7.0 and above. It is not on Google Play, so you download it directly from the ok77 website. Enable "Install from unknown sources" in your Android settings before installing. The app supports all games, deposits, withdrawals and live chat. iOS users can access the full site via mobile browser with a similar experience.

ok77's VIP programme has six tiers: Bronze, Silver, Gold, Platinum, Diamond and Black Diamond. Your tier is calculated on monthly betting turnover. Each level gives you a higher daily cashback rate (from 0.9% at Bronze to 1.4% at Black Diamond), a higher daily withdrawal limit and a birthday bonus from Silver upward. Black Diamond members also get a personal account manager. Cashback is credited automatically every day with no wagering requirement attached. Full tier details are at ok77 Bonus & VIP.

ok77 runs 24/7 live chat directly on the website and in the app. For non-urgent matters, email [email protected]. Live chat is the fastest option — typical response time is under two minutes, including during major cricket and football events. Support agents can help with deposit issues, withdrawal delays, KYC document queries, bonus activation and account security. There is no telephone support — all help goes through live chat and email.
