Registration & Account

To register on ko33, registration page Enter your mobile number or email address, set a strong password, and verify with an OTP. The whole process takes just 2–3 minutes. Once registered, your welcome bonus is credited automatically.

Each person may hold only one account on ko33. Opening multiple accounts using the same phone number, email address, or device is strictly prohibited and may result in all associated accounts being closed. Any bonuses and winnings may also be forfeited as a result.

KYC (Know Your Customer) is an identity verification process. To make a withdrawal, you'll need to upload a photo of your National ID (NID) or passport. This keeps your account secure and helps prevent fraud. KYC verification is typically completed within 24 hours.

Some details — such as your full name and date of birth — generally cannot be changed after registration as they are tied to KYC verification. To update your contact number or email, go to Account Settings. For any other issues, reach out to the support team.
Deposit & Payment

After logging in, go to the "Payment" or "Deposit" section. Select Mobile Pay, Nagad, or Rocket. Enter the amount and send the payment to the provided number. Submit your transaction ID — your balance is usually credited within 5–10 minutes. For more details, Payment page here.

The minimum deposit at ko33 is ৳300 and the minimum withdrawal is ৳500. The maximum daily withdrawal limit depends on your account level and verification status. Members who have completed KYC verification are eligible for higher withdrawal amounts.

Bonuses & Promotions

After opening a new account, a 100% welcome bonus is automatically added on your first deposit. So if you deposit ৳1,000, you'll receive an extra ৳1,000 in bonus funds. A wagering requirement must be met before the bonus can be withdrawn — for full details, Terms & Conditions read more.

A wagering requirement means you must place a specified amount of bets using your bonus funds before you can withdraw. For example, a 5x wagering requirement on a ৳1,000 bonus means you need to bet ৳5,000 in total. Once the requirement is met, the bonus converts to real balance and becomes withdrawable.

If you have a net loss on any given day, you'll receive a cashback percentage of that amount. Cashback is typically credited to your account by the following morning. The amount depends on your loyalty level and betting volume.
