The Definitions You'll See Most

Return to Player, shown as a percentage, tells you how much a slot or table game pays back over millions of spins. A 96% RTP means the game returns ৳96 for every ৳100 wagered on average over the long term.

The statistical advantage the platform holds on a game, expressed as a percentage. A 2% house edge means the platform expects to keep ৳2 from every ৳100 wagered over time, across all players combined.

How often and how big a slot pays. High volatility means fewer wins but larger payouts when they hit. Low volatility delivers smaller wins more frequently, smoothing out your balance swings across a session.

The total amount you need to bet before you can withdraw certain bonus funds or winnings. A ৳500 bonus with 10x turnover requires ৳5,000 in bets before the balance converts to withdrawable cash.

A large prize pool in a slot or progressive game that grows with every bet across the network until one player triggers the win condition. Some jackpots reset to a seed amount after payout.

A real person dealing cards or spinning a wheel in a studio, streamed to your device in real time. You place bets through the interface and watch the outcome unfold on camera.

Betting, Payment and Security Terms

A betting format that removes the draw by giving one team a goal advantage or deficit. If you back Team A at minus one goal, they must win by two or more for your bet to pay.

A market where you predict whether the total score, goals or points in a match will be above or below a line set by the platform. Over 2.5 goals wins if the match finishes with three or more.

The number of times you must wager a bonus amount before you can withdraw it. A ৳1,000 bonus with 8x rollover means you need to place ৳8,000 in qualifying bets to unlock the funds.

A mobile payment app that holds your balance digitally. bKash, Nagad and Rocket are the e-wallets we support for deposits and withdrawals, letting you move funds without a bank card or visit

Know Your Customer verification, where you upload an ID document and proof of address so we can confirm your identity. Completing KYC unlocks full withdrawal limits and keeps your account compliant with regional rules.

Daily, weekly or monthly caps you set on deposits or bet amounts to control how much you spend. You configure these in account settings, and once the limit is reached the platform blocks further transactions until the period resets.

Questions About Features These Terms Describe

Tap the info icon on the slot thumbnail in the lobby. The panel shows RTP, volatility and maximum win where the provider supplies that data. Not every studio publishes RTP publicly, so some games display only the title and studio name.

Open account settings and go to the promotions tab. You'll see your active bonus, the original turnover requirement and how much you've wagered so far. The tracker updates after each qualifying bet settles.

Yes. In account settings under payment controls, choose bKash from the method list and set a daily or weekly cap. The limit applies only to bKash transactions and leaves Nagad and Rocket unrestricted unless you configure those separately.

If the handicap is a whole number and the adjusted score ties, your stake is refunded. For half-goal and quarter-goal handicaps, part of your stake may win and part may push, depending on the exact line you backed.

Most live tables display the house edge or RTP in the game info panel once you open the stream. Baccarat, blackjack and roulette variants each have different edges depending on the bet type and rule set the studio uses.

We aim to review documents within a few hours during business days. You'll receive a confirmation notification once your account is verified, and your withdrawal limits will update automatically so you can request payouts to your registered e-wallet.
