Know the Words, Choose Better Games

Every slot, live table and sports market uses shorthand that shapes how you play. RTP tells you the theoretical return a slot pays over millions of spins; volatility hints at whether wins arrive steadily or in rare bursts. On the sportsbook side, terms like Asian handicap and over/under define exactly what you're backing. When you recognise rollover, you'll know how many times

a bonus must be wagered before withdrawal. We explain each piece of jargon here so you spend less time guessing and more time deciding which game or market fits your style and bankroll.

Email Send your question to our support address with the game or page where you saw the term. We'll reply with a plain explanation and a screenshot if it helps clarify the context.
FAQ Updates We add new entries to this glossary each month based on the questions you send. If a term keeps coming up, we'll publish a definition here so every player can find it without waiting.

Essential Definitions

Start with the fundamentals—these six terms appear in slot descriptions, live-table rules and provider screens across our lobby.

Return to Player: the percentage a game is programmed to pay back over a very long run. A ninety-six percent RTP means the game returns ninety-six taka for every hundred wagered, on average across millions of spins.

The mathematical advantage the platform holds on a given game. It's the inverse of RTP—if RTP is ninety-six percent, the house edge is four percent. Lower house edge means better long-term odds for you.

Also called variance. High volatility slots pay less often but offer bigger wins when they hit; low volatility games deliver smaller, steadier returns. Choose high for thrill, low for longer play on the same bankroll.

The total amount you've staked across spins or rounds. Bonus terms often require you to reach a specific turnover—say, twenty times the bonus—before you can withdraw winnings tied to that offer.

A large prize pool, either fixed or progressive, that one spin or hand can unlock. Progressive jackpots grow as players across the network contribute a fraction of each bet until someone wins the entire pot.

A real person dealing cards or spinning a wheel in a studio, streamed to your screen in real time. You place bets digitally while watching the physical game unfold, blending online speed with land-based authenticity.

Next-Level Terms

Once you're comfortable with game mechanics, these definitions cover sportsbook markets, payment flow and account-security steps.

A two-way betting market that removes the draw by giving one team a virtual head start or deficit. If you back Team A at minus-one, they must win by two or more goals for your bet to succeed.

A market on the total goals, runs or points in a match. Over two-point-five means you win if three or more goals are scored; under wins if the match ends with two or fewer.

The number of times you must wager a bonus amount before converting it to withdrawable cash. A twenty-times rollover on a thousand-taka bonus means you stake twenty thousand taka in qualifying games before cashing out.

A mobile payment account like bKash, Nagad or Rocket that lets you deposit and withdraw without entering card details each time. Transfers usually clear faster than traditional bank routes when both sides support the same rail.

Know Your Customer: the process where you upload identity documents so we can verify your name and address. Completing KYC unlocks higher withdrawal limits and keeps your account compliant with platform policies.

Optional account controls that cap how much you can deposit or wager in a day, week or month. You set these in account settings; once active they stay locked for the duration you choose.

Common Questions About Features

These answers show how the terms above connect to everyday tasks—filtering slots by RTP, checking rollover progress or setting account limits.

We display RTP and volatility tags on each slot tile where the provider shares that data. Use the lobby filters to sort by high RTP or pick low-volatility games when you want steadier play on a smaller bankroll.

Open your account dashboard and tap the active-bonus panel. You'll see the original amount, the rollover multiplier required and how much turnover you've logged so far across qualifying games.

Each live-dealer table shows game rules in an info button. Tap it to see the house edge for the main bet and any side bets available on that table.

Raising a limit takes effect after a twenty-four-hour cooling-off period; lowering or removing a limit applies immediately. You manage limits in the account-security section of your profile.

Yes. We offer Asian handicap and over/under lines for international and BPL cricket matches when the fixture goes live. Check the sportsbook match page for the full list of markets.

We don't add platform fees to e-wallet deposits. Your payment provider may apply its own transaction charge; that amount is set by bKash, Nagad or Rocket and appears in their app before you confirm.
