This rule is strictly enforced to ensure fair and responsible gaming.

If you want to close your bb4 account, contact our support team and submit a request. Before closing your account, make sure your balance is zero and there are no active bets or pending transactions.

We always encourage our members to build healthy gaming habits.
Everything you need to know about BDT payments, deposits, and withdrawals.
Bb4 supports the popular mobile banking methods used in Bangladesh, including bKash, Nagad, and Rocket. All transactions are completed in Bangladeshi Taka (BDT), so there is no hassle with currency conversion. To make a deposit, select your preferred payment method and follow the instructions. Visit the Payment page for details on the minimum deposit amount. We always use up-to-date payment technology to ensure fast and secure transactions.
Withdrawal requests typically take 24 to 72 hours to process, though in most cases they are completed much sooner. Your account verification must be complete before a withdrawal can be approved. Make sure your payment details are correct and match the number registered to your account. If you do not receive your payment within the expected timeframe, please notify our support team. We do our best to settle every withdrawal request as quickly as possible.
It may take a few minutes for your balance to update after a deposit, so wait a moment and refresh the page. If your balance still does not appear after 15 minutes, retrieve the transaction reference number from your payment app. Contact our support team with that reference number and describe the issue. Our team will verify the matter quickly and update your balance. To avoid this issue in the future, make a habit of saving your payment reference numbers.
