Frequently Asked Questions

Have questions about the Terms & Conditions?

To register, you need an active mobile number, an email address, and to be at least 18 years old. For withdrawals, you will need to complete KYC verification using your national ID.

For example, if you receive a ৳1,000 bonus with a 5x wagering requirement, you must place a total of ৳5,000 in bets before the bonus funds can be withdrawn. Each bet must have minimum odds of 1.50.

Withdrawals for KYC-verified accounts are typically processed within 1–24 hours. First-time withdrawals may take slightly longer due to additional verification requirements.

If an account is closed for reasons other than a rule violation, valid deposits and winnings will be returned. However, the entire balance may be forfeited in cases of bonus abuse or fraud.

A notice will be sent to your registered email address and posted on the platform ahead of any significant changes. The date of the latest update is always shown at the top of this page, so we recommend checking back regularly.
