Know the Language, Play the Account Better

When you understand what house edge actually means, you pick tables differently. When you know how rollover works, you read a promotion without surprises. The terms on this page cover four areas: how games are built (RTP, volatility, RNG), how markets are priced (odds, handicap, over/under), how your money moves (e-wallet, withdrawal verification, KYC), and how account features function (wager requirement, session

history, wallet balance). Dhaka and Chattogram players who check these definitions before their first session tend to switch between cricket betting and live tables more confidently — and that is the whole point of having the lobby in one place.

Explore the Core Casino Terms

These six entries cover the mechanics you encounter most often when switching between slots, live tables and crash games on the platform.

RTP stands for Return to Player — the percentage of total bets a game pays back over many rounds. Where a provider publishes it, you will see it in the game detail panel.

House edge is the built-in mathematical advantage the platform holds on each game. A lower house edge, as in many live baccarat titles, means your money lasts longer on average.

Volatility describes how often and how large a slot pays out. High-volatility titles like Gates of Olympus pay infrequently but in larger amounts; low-volatility slots pay smaller amounts more often.

A wager requirement is the total amount you must bet before a bonus balance can be withdrawn. It is always expressed as a multiple — for example, 10x means ten times the bonus amount.

A jackpot is the highest prize pool attached to a slot or prize-style game. Some are fixed amounts; others accumulate across rounds until one qualifying spin or hand claims the pool.

A live dealer is a real person dealing cards or spinning a wheel from a studio camera feed. Evolution and Pragmatic Play both supply live dealer tables streamed directly into the lobby.

Switch Between Odds, Payments and Account Definitions

This set covers the terms that appear most often in sportsbook markets, payment flows and your account verification steps.

Asian handicap removes the draw outcome and adjusts one team's starting score by a fraction or whole number. It is common in cricket and football markets and narrows every bet to two possible outcomes.

Over/under is a market on whether a combined score or stat — total runs in a cricket innings, for example — will land above or below a set number the platform publishes before the match.

Rollover is another word for wager requirement, used specifically in promotional terms. Complete the stated rollover before the credited amount becomes available for withdrawal to your bKash or Nagad wallet.

An e-wallet is a mobile money account — bKash, Nagad or Rocket — that links to your platform wallet. Deposits are initiated from within your phone's wallet app and confirmed with your PIN before the balance clears.

KYC stands for Know Your Customer — the identity verification step where you submit a national ID or similar document so the platform can confirm account ownership before processing a withdrawal.

RNG stands for Random Number Generator, the software engine that determines slot and virtual game results. A certified RNG means each round is statistically independent of the one before it.

Browse Common Questions About Platform Features

These questions are about how the terms you have just read connect to actual steps on the platform — deposits, withdrawals, game selection and account flow.

RTP is only shown where the provider publishes it. In slots from Pragmatic Play or PG Soft, tap the game info icon before loading the round to check if a figure is available.

Once KYC is complete, withdrawal requests to your bKash account are processed through the standard verification queue. Incomplete KYC will hold the request until the required document is reviewed.

If you request a withdrawal before meeting the stated rollover, the bonus portion of your balance is removed and only the deposited amount is processed to your Nagad or Rocket account.

Asian handicap formats are available on selected cricket markets, including BPL fixtures when listed. Check the market panel on the sportsbook screen — each match shows which handicap lines are open.

Open the promotions section inside your account. Each active offer shows a progress bar with the amount wagered against the total rollover required, updated after each qualifying round or bet.

Both deposit to the same account wallet, but the sending steps differ inside each mobile app. bKash uses Send Money to the merchant number shown; Rocket follows its own payment code flow before confirming.
