Once you make your first deposit on a new account, a 100% bonus is credited automatically. For example, a ৳1,000 deposit gives you a total balance of ৳2,000.
To withdraw a bonus, you must meet the specified wagering requirements.
A wagering requirement means you must place bets totalling a specified multiple of your bonus amount before you can withdraw. For example, a ৳1,000 bonus with a 5x wagering requirement means you need to wager a total of ৳5,000.
How to complete it quickly:
Yes. The wagering requirement for the welcome bonus must be met within 30 days of the bonus being credited. Expiry periods for reload bonuses and special offers vary by promotion. Full terms for each bonus can be viewed in your account.
A reload bonus is a special bonus on repeat deposits, exclusively for existing members. It's available once a week or once a month. You'll receive a notification when you log in, or you can check the Promotions section.

Generally, no — once a bet is confirmed, it cannot be cancelled. However, there are a few exceptions:
