We've written out the casino, slot and betting terms you'll see in our lobby and on game screens — what RTP means, how volatility shapes your session, what rollover asks you to do before withdrawal.

Know the term, make the call

A slot's volatility tells you whether it pays often or waits for bigger hits. RTP shows the long-run return percentage the studio programmed. Rollover sets how many times you turn a bonus over before you can withdraw. When you understand what each term does, you choose games that fit your bankroll and style — high-variance slots if you're chasing feature wins, low

house-edge tables if you want steadier rounds, Asian handicap markets if you follow cricket and want tighter lines. We keep definitions here so you're never guessing what a game label or promo rule actually means before you open your account and start playing.

The words you'll see on every game screen

These six terms appear across slots, tables and live dealer screens — the building blocks of how a game pays and how the house keeps its edge.

Return to Player — the percentage a slot or table game is programmed to pay back over millions of rounds; a 96% RTP means the game returns 96 taka for every 100 wagered in the long run.

The mathematical advantage the platform holds on each bet; calculated as 100% minus RTP, so a 2% house edge means the game keeps two taka per hundred wagered on average over time.

How a slot spreads its payouts — low volatility pays smaller wins frequently, high volatility waits longer between hits but delivers bigger prizes when features land; also called variance.

The amount you stake on a single spin, hand or bet; sometimes called turnover when platforms describe how much total action you need to complete a bonus requirement before withdrawing.

A large prize pool that builds from a portion of every bet placed on a slot or network of slots, paying out when a player hits the jackpot trigger combination or random event.

A casino table streamed in real time from a studio, where a human dealer shuffles cards or spins the roulette wheel and you place bets through the interface on your screen.

Betting markets, payment words and account rules

These definitions cover sportsbook lines, wallet jargon and the account steps you'll meet when you deposit via bKash, Nagad or Rocket and request your first withdrawal.

A betting market that gives one team a goal or run advantage to level the odds, removing the draw outcome; popular in cricket and football, where you back a side to win after the handicap is applied.

A bet on whether the total goals, runs or points in a match will finish above or below the line the platform sets; you're not picking a winner, only the combined score.

The number of times you must wager a bonus amount before you can withdraw winnings tied to it; a 10× rollover on a 500 taka bonus means you turn over 5,000 taka in bets first.

A mobile payment app that holds your balance and lets you send funds instantly; bKash, Nagad, Rocket and Upay are the e-wallets we accept for deposits and withdrawals in supported Bangladesh regions.

Know Your Customer — the identity verification step where you upload a national ID or passport scan so the platform confirms your details before processing larger withdrawals or account upgrades.

An optional account control that caps how long you can stay logged in or how much you can deposit in a day, helping you manage your play time and spending in one place.

How to use the features these terms describe

Practical answers about finding RTP on a game card, checking rollover progress, picking the right volatility and understanding how Asian handicap lines move before kickoff.

Tap any slot or table card in the lobby and the detail panel shows RTP percentage when the studio publishes it; if you don't see a number the provider hasn't exposed that data for the title.

Open your account page and tap the active bonus tile; the progress bar shows how much you've wagered and how much turnover remains before the bonus converts to withdrawable balance.

Choose low volatility when you want frequent small wins that keep your balance steady; pick high volatility if you're chasing big feature payouts and can handle longer dry stretches between hits.

The favourite starts 1.5 runs behind; they must win by two or more runs for your bet to pay, removing the draw and tightening the line compared to a straight match-winner market.

Only the bets you place count as turnover; deposits and withdrawals through bKash, Nagad or Rocket move money but don't add to your rollover total, so you still need to wager the full amount.

We trigger identity verification when your cumulative withdrawals reach a threshold or when account activity flags a review; upload your national ID scan through the account security page to clear the check.
