Video Slots
Modern slots with five or more reels, featuring animations, bonus rounds, and free spins. Gates of Olympus by Pragmatic Play is a well-known example of this category.
Jackpot Slots
In progressive jackpot slots, a portion of every bet is added to a prize pool, which can grow to a large amount. Microgaming leads the way in this type of slot.

| VIP Weekly Cashback | Bronze: 0.2% — Diamond: 1.2% | Tier-based | No wagering required |
Wagering Requirement
Before withdrawing winnings from a bonus, you must wager a specified amount. This amount is calculated on the bonus only, not on your deposited funds.
Game Contribution
Not all games contribute equally toward the wagering requirement. Slot games typically contribute in full, while table games contribute partially. Check the bonus terms page for full details.
Maximum Bet Limit
A specific bet limit applies per round while a bonus is active. Exceeding this limit may result in the bonus being cancelled — so read the terms before you play.
Bonus Validity & Cash-Out
Each bonus has a set validity period. If the wagering requirement is not completed before it expires, the bonus and any associated winnings may be forfeited. A maximum cash-out limit also applies.
A Practical Example
Say you deposit ৳1,000. With the 100% welcome bonus, you receive an additional ৳1,000 in bonus funds — making your total balance ৳2,000.
The 25x wagering requirement on the bonus means — ৳1,000 bonus × 25 = a total of ৳25,000 must be wagered. After that, winnings earned from the bonus can be withdrawn.
