Bonus Terms

Understanding the wagering requirement, bonus expiry, and which games count toward wagering before claiming the 89db bat welcome bonus will help you get the most out of it. 89db bat VIP members also receive weekly cashback in addition to bonuses.

A wagering requirement is the total bet amount you must complete before bonus funds can be withdrawn. At 89db bat this is 10 times the bonus amount. For example, depositing ৳1,000 gives a 150% bonus of ৳1,500, making your balance ৳2,500 — but you must place a total of ৳15,000 in bets (৳1,500 × 10) before the bonus funds can be withdrawn. Every bet you place counts toward this total.

First, log in to your account from the 89db bat Login page or create a new account (for players aged 21+). Then make your first deposit of at least ৳100. After depositing via bKash, Nagad, or Rocket, 89db bat will automatically credit your account with a 150% bonus of up to ৳10,000.

89db bat bonuses have a set expiry period — if the wagering requirement is not completed within that time, the bonus may be cancelled. The exact expiry is shown on the promotions page when you claim the bonus. It is best to start playing soon after receiving a bonus. For any questions about expiry, contact 24/7 live chat.

Slot games generally count 100% toward wagering. Live casino table games such as Baccarat or Roulette may count partially or not at all. The full list of game contribution rates for 89db bat can be found in the promotion terms. Visit the 89db bat Slots page for a list of popular slot games — these are the most effective for completing wagering.

No, bonus funds cannot be withdrawn directly. Winnings earned from a bonus only become withdrawable after the wagering requirement has been met. However, you can withdraw your own deposited funds at any time (minimum withdrawal ৳500). 89db bat always states bonus terms clearly on the promotions page.
VIP

VIP and Cashback

89db bat's three VIP tiers give you cashback on your net losses every week. Regular play can move you up to a higher tier automatically. Visit the 89db bat VIP page for full details.

89db bat VIP members receive weekly cashback on their net losses, credited directly to their account. Higher tiers also get priority support and access to exclusive promotions. The VIP program is a way to reward regular players over the long term.

89db bat has three VIP tiers:
Bronze: up to 0.5% weekly cashback.
Silver: up to 1.0% weekly cashback.
Gold: up to 1.5% weekly cashback.
Cashback is based on the total net losses for the week.

Cashback is calculated on net losses — that is, total losses minus total winnings for the week. Example: as a Silver member, if your net loss for the week is ৳20,000, your cashback will be ৳20,000 × 1.0% = ৳200. This is credited directly to your account and can be used for further play.

Your VIP tier at 89db bat depends on your consistency of play — the more regularly you play, the better your chances of moving to a higher tier. Specific turnover figures are not published, but active players are assessed automatically. Contact live chat support for the latest information on tier changes.

The minimum deposit at 89db bat is ৳100 for all methods. You can get started with this amount via bKash, Nagad, or Rocket mobile banking. Starting small lets you try out your preferred games. The minimum withdrawal amount is ৳500.

89db bat supports three methods for both deposits and withdrawals: bKash, Nagad, and Rocket (Rocket is Dutch-Bangla Bank's mobile wallet). These are the most widely used mobile banking services in Bangladesh, so transactions can be completed easily from any smartphone.

Slots & Jackpots

Slots & Jackpots

Gates of Olympus, Fortune Tiger, or Aviator — find answers to common questions about slots and jackpot games here. To browse popular slot games, visit the 89db bat Slots page.

In a progressive jackpot, a small portion of every bet placed by every player is added to the prize pool. The more people play, the larger the jackpot grows. When a lucky player hits the jackpot, they receive the entire pool and it resets back to zero. 89db bat offers several progressive jackpot slots.

If you want to play longer on a smaller budget, choose low volatility games — these pay out small wins frequently. If you are looking for bigger wins, you can go for high volatility games, but be prepared for longer losing streaks. A common guideline is to keep each bet within 1–2% of your balance.

Free spins are complimentary reel spins available within a slot game — they are usually triggered when three or more special scatter symbols land at the same time. This is a built-in game feature, not a separate bonus. Winnings from free spins are added directly to your account. Some games also offer a buy feature that lets you purchase free spins.

Volatility refers to how often and how much a slot game pays out. Low volatility games pay out frequently but in smaller amounts; high volatility games pay out less often but in larger amounts. For a mid-range budget, mid volatility games — such as Gates of Olympus (Pragmatic Play) or Mahjong Ways (PG Soft) — can be a good option.
