Common Questions About Bonuses

What users want to know most

Yes, the welcome bonus is available once per account and applies to the first deposit only. That said, you can continue enjoying regular benefits through the weekly reload bonus, cashback, and VIP rewards. Members who stay active on b650mk long-term often end up receiving more in total bonuses than the welcome offer alone.

Bonus funds cannot be withdrawn directly — you must first meet the designated wagering requirement. Cashback bonuses are the exception, as they are wager-free and available for immediate withdrawal. Once wagering is complete, any winnings earned from the bonus are transferred to your main balance and can then be withdrawn via bKash or Nagad.

The welcome bonus and weekly reload are generally applied automatically, so no separate promo code is needed. Special festival bonuses may require a promo code, which will be displayed on the site's homepage or in your notifications. If you leave the promo code field empty at the time of deposit, the default bonus will apply.

The wagering requirement means you must place bets totalling the bonus amount multiplied by the specified number. For example, a ৳1,000 bonus with a 15x wagering requirement means you need to wager a total of ৳15,000. Each bet contributes incrementally toward the requirement, and your progress is displayed as a percentage in the bonus wallet.
