After registration, your first deposit will automatically earn you a 100% welcome bonus — up to ৳10,000. So if you deposit ৳1,000, you'll start betting with ৳2,000 in total. A wagering requirement must be met before the bonus can be withdrawn.
Before withdrawing bonus funds, you must wager a specified amount — this is the wagering requirement. For example, a ৳1,000 bonus with a 10x wagering requirement means you need to place ৳10,000 in bets. Learn more in the Terms & Conditions you will receive.

After adding a selection to your bet slip, you'll see the "Free Bet" option — select it. If your free bet wins, only the profit is credited to your account; the original stake amount is not returned. Make sure to use it before it expires.
First, check the bonus section in your account. If it's not there, In the Help Center Get in touch. Bonus-related complaints are typically resolved within 24 hours.
During registration, you'll find a promo code field on the second step — enter your code there. If you already have an account, you can enter a promo code on the deposit page. Any valid code will automatically apply an additional bonus to your account.
77b uses decimal odds. Formula: Profit = Bet × Odds – Bet
Example: You bet ৳100 at odds of 2.50. If you win, you receive ৳100 × 2.50 = ৳250 — a profit of ৳150.
The higher the odds, the lower the chance of winning — but the bigger the payout if you do.
Live Betting or In-Play Betting means placing bets in real time while a match is in progress. On the betting page Go to the "Live" section — watch ongoing matches, read the game situation, and place your bet. Odds change by the second, so act fast.

VIP members enjoy higher maximum bet limits.
