FAQ
Here you'll find answers to the most frequently asked questions about gb99b promotions and bonuses.
After creating a new account at gb99b, your welcome bonus activates automatically with your first deposit. A minimum deposit of ৳500 qualifies you for the offer, and the bonus can be up to 100% of your deposit, capped at ৳5,000. Whether you pay via bKash, Nagad, or Rocket, the bonus lands in your wallet within minutes. This bonus must be claimed within 7 days of registration — after that, the offer expires. A 5x wagering requirement applies, which can be completed across both Sports and casino sections.
Gb99b's weekly cashback is calculated every Monday by 10:00 AM, based on your net losses from the previous week (Monday to Sunday). Net loss is your total amount wagered minus your total winnings. You receive 10% of that amount as cashback, deposited directly into your wallet, up to a maximum of ৳3,000. To qualify, you need to place at least ৳1,000 in bets during the week. Once the cashback lands in your wallet, you can use it on any game or bet — and withdraw it once the wagering requirement is met.
At gb99b, you generally cannot have more than one bonus active at the same time — however, certain offers can be combined, and these are noted on the promotions page. For example, the weekly cashback and a cricket free bet can both be active in the same week since they are different types of offers. Two deposit bonuses, however, cannot run simultaneously. Check the terms section of the relevant promotion for full details. For any questions, the gb99b support team is always on hand to point you in the right direction.
To withdraw winnings earned from a gb99b bonus, you must first meet the applicable wagering requirements. For the welcome bonus, the wagering requirement is 5x — meaning you need to place bets totalling five times the bonus amount. Once the requirement is met, your bonus balance converts to real balance and can be withdrawn via bKash or Nagad. For free bets, only the winnings are withdrawable, not the stake itself. Withdrawals are typically processed within 1–4 hours.
Joining the gb99b VIP Program is fully automatic — no separate application needed. Your VIP tier is determined automatically based on your monthly deposits and betting activity. A minimum monthly deposit of ৳10,000 qualifies you for the first VIP tier, which comes with up to 30% reload bonuses, faster withdrawals, and dedicated support. Higher tiers unlock birthday bonuses, exclusive tournament invitations, and special gifts. To maintain your VIP status, you need to keep up the required activity each month.
The easiest way to stay updated on gb99b's latest promotions is to visit this page regularly — new offers are added every week. When logged in, the gb99b promotions section shows personalized offers tailored to your account activity. New promotions typically go live every Monday and on the eve of major festivals.
