Understanding the terms speeds up your account decisions

When you know what volatility means, you can pick slots that match how long you want to play. When rollover and turnover are clear, you know exactly what a promo asks before you opt in. When you recognise KYC and e-wallet, withdrawal requests make sense the first time. Our glossary covers game mechanics like RTP and house edge, betting terms like Asian

handicap and over/under, and the payment language around bKash, Nagad and Rocket that keeps your account moving. We define each term the way our support team would explain it — plain language, no jargon piled on jargon, so you spend less time guessing and more time in the lobby.

Game mechanics and casino fundamentals

Return to Player — the percentage a slot or table game is designed to pay back over millions of rounds. A ninety-six percent RTP means the game returns ninety-six taka for every hundred wagered, on average, long term.

The mathematical advantage the platform holds on each bet. If the house edge is two percent, the platform expects to keep two taka from every hundred wagered, averaged across all players and many rounds.

How often a slot pays and how big those wins are. High volatility slots pay less frequently but can deliver larger wins; low volatility slots pay smaller amounts more often, stretching your balance across more spins.

The total amount you must bet before you can withdraw bonus funds or winnings tied to a promotion. If a promo requires twenty times turnover on a hundred-taka bonus, you need to place two thousand taka in bets.

A large prize pool that grows as players bet, or a fixed top prize in certain slot features. Progressive jackpots climb until someone wins; fixed jackpots pay the same amount every time the feature triggers.

A real person streaming a casino table from a studio. You place bets through our interface; the dealer handles cards, dice or the roulette wheel on camera, and results appear in real time on your screen.

Odds, payment and verification terms

A betting market that removes the draw by giving one team a goal advantage or deficit. If you back a team at minus one, they must win by two goals for your bet to pay; minus half goals create push refunds.

A bet on whether the total goals, runs or points in a match will finish above or below a line the sportsbook sets. Over two point five goals wins if three or more are scored; under wins with two or fewer.

The number of times you must wager a deposit or bonus amount before you can request a withdrawal. Same concept as turnover; platforms use both words to describe the same requirement in different promo terms.

A mobile payment account like bKash, Nagad or Rocket that holds your balance and sends funds instantly. You top up your a880 account by sending from your e-wallet app to the number we display at the cashier.

Know Your Customer — the verification process where you upload your national ID or passport and a recent selfie so we can confirm your identity before processing withdrawals. Keeps accounts secure and meets regional compliance rules.

Daily, weekly or monthly caps you set in your account to control how much you deposit or wager. Once you hit the limit, the system blocks further deposits or bets until the period resets, helping you stay within budget.

Using platform features these terms describe

RTP appears in the game-info panel when you tap the information icon on a slot tile, or inside the game window itself if the provider displays it. Not every studio shows RTP publicly; when it's available, we surface it.

Open your account wallet, tap the active bonus row, and you'll see how much turnover you've completed and how much remains before the bonus balance converts to withdrawable funds. Updates every time you place a qualifying bet.

You can lower a limit instantly; raising one requires a twenty-four-hour cooling-off period to take effect. This delay helps you stay within the budget you originally chose and prevents impulsive increases during a session.

Upload a clear photo of your national ID or passport and a recent selfie holding the same document. Our team checks both within a few hours and approves your account for withdrawals once the images match and are readable.

Quarter-goal and half-goal handicaps never land exactly on the line; whole-goal handicaps return your stake as a push if the margin equals the handicap. Our bet slip shows whether a push is possible before you confirm.

Most e-wallet transfers from bKash, Nagad or Rocket appear in your account within sixty seconds. If the balance doesn't update, check your e-wallet transaction history and contact live chat with the reference number for an instant trace.
