This glossary covers the language you see across the 89bat lobby — from odds formats on cricket and football markets to wallet terms when you move money with bKash or Upay.
Misreading a single term can change how you approach a game or a bet. When you know what house edge means, you can compare two table games without guessing. When you understand rollover, you read a information condition the same way the platform does.
Each family of terms belongs to a specific part of the platform. Knowing which screen surfaces which words makes the lobby easier to navigate.
Terms like RTP, volatility, and house edge appear on game info panels and paytables. You find them by opening a game title — such as Lucky Spinners or Roulette DiamondSpin — and tapping the information icon before you place a wager.
Asian handicap, over/under, and decimal or fractional formats appear on the sportsbook market rows for cricket, football, and other events. The odds format can usually be switched in your account settings to whichever display you are comfortable reading.
Deposit, withdrawal, e-wallet, and balance terms appear on the cashier screen. When you select bKash or Upay as your method, the screen shows the transaction reference field and the minimum and maximum amounts set for that rail.
Rollover, turnover, and wagering requirement appear in the terms attached to any information. Always read the conditions shown in your account's information section before you use a gameplay balance, so you know which game categories count toward clearing it.
These are the foundational terms you will encounter most often across the lobby and sportsbook.
RTP stands for Return to Player. It is the percentage of all wagered money a game is designed to pay back over a very large number of rounds. A higher RTP means the game retains a smaller portion statistically, though individual sessions vary widely.
House edge is the mathematical advantage the platform holds on any game or bet type, expressed as a percentage of each wager.
Volatility describes how a slot distributes payouts. High-volatility slots pay less often but in larger amounts when they do hit. Low-volatility slots pay smaller amounts more frequently. The right choice depends on your session length and the balance you are comfortable risking between significant wins.
A wager or turnover requirement is the total amount you must bet before a gameplay balance becomes withdrawable. For example, if a condition requires ten times the gameplay amount, you must place bets totalling that value across qualifying games before a cash-out is permitted under those terms.
A jackpot feature is a prize-pool mechanic built into some slot titles where a large fixed or accumulating prize can be won through a specific in-game trigger. The prize size and trigger conditions are set by the game provider and displayed in the game's own paytable or rules panel.
A live dealer game streams a real croupier or host dealing cards, spinning a roulette wheel, or running a game show format from a studio.
These terms come up most often in the sportsbook markets, at the cashier, and during account setup or verification.
Asian handicap is a betting format that removes the draw outcome by giving one side a virtual head start or deficit, expressed as a fractional or whole number. It is widely used for football markets.
Over/under is a market where you bet on whether a measurable figure — total runs scored, total goals, total corners — will finish above or below a number set by the sportsbook. It does not require you to pick a winner. Cricket and football both carry over/under markets on 89bat.
Rollover is another word for the wagering requirement attached to a promoted balance. It specifies how many times that balance must be turned over in qualifying bets before it converts to real withdrawable funds. Always check the rollover multiplier and the eligible game categories in your account's active-offer details.
An e-wallet deposit moves funds from a mobile money account — bKash or Upay, for Bangladesh — directly to your 89bat balance.
KYC stands for Know Your Customer. It is the identity verification process platforms use to confirm who holds an account. You may be asked to submit a national ID document and a selfie.
These are account-level controls that let you set boundaries on your own activity — session budgets, cooling-off periods, or voluntary restrictions. On 89bat, the account settings area is where you can review any controls the platform makes available. Availability and scope depend on local law and eligible regions.
Terms rarely appear alone. On the Live Cricket Pitch market, you might see an Asian handicap line and an over/under run total sitting side by side on the same fixture card.
Asian handicap and over/under lines both appear on the Live Cricket Pitch market card. Knowing the difference lets you choose the market that matches your read on the match rather than defaulting to whichever one looks familiar.
Lucky Spinners displays RTP and jackpot feature rules in its in-game info panel. Open it before your first spin so you understand how the prize-pool mechanic triggers and what the base volatility means for your session length.
When you deposit via bKash, the cashier shows your transaction reference immediately. Keep it until the balance posts. If there is a delay, support can trace the transaction using that reference and your registered bKash number.
The rollover multiplier for any information is listed in your account's information detail page, not on the lobby banner. Read the eligible-game list there before you start wagering the gameplay balance.
If a definition here does not fully answer what you saw on a game screen or in your account, the support routes below are the published channels on 89bat.
Access the live chat widget from any page while signed in. Describe the term and where you saw it — game name, section, or cashier step — so the agent can pull up the same screen and walk through it with you.
Send a message through the contact form in your account dashboard. Include a screenshot if possible. Email is the right route for detailed questions about information conditions, KYC documents, or transaction references that need a written response.
The help centre articles in your account area cover wallet steps, verification requirements, and common game mechanics. Search by the term you are unsure about before opening a chat so you can reference the article number if the agent needs context.
These questions cover how the terms translate into real actions on the platform.
Open the game title and tap the information or rules icon before you start. RTP is displayed there when the provider makes it available. Not every title exposes this figure, but Bigtime Gaming, PG Soft, Habanero, and Microgaming titles generally include a paytable or info panel.
Go to the information or bonus section of your signed-in account. Each information has a detail view that lists the rollover multiplier, eligible game categories, and the expiry date. Read that page directly rather than relying on the lobby banner, which only summarises the headline.
Completing KYC is typically required before a withdrawal request can be processed. Upload the requested documents through the verification section of your account. Once the review clears, your withdrawal options via bKash or Upay become fully active. Check your account for the exact documents the platform requests.
Yes. The sportsbook odds display can usually be changed in your account settings between decimal, fractional, and other supported formats. Decimal is the default for most Bangladesh players and shows the total return per unit staked including your original wager amount.
The reference number generated at the cashier when you initiated the deposit is the key trace point. Keep that number and contact support through live chat or email with your registered bKash number and the reference. Support can verify the transaction against the payment records on the platform side.
Eligible categories vary by offer. The detail page for each active information in your account lists which sections — sportsbook, slots, live casino tables — count and at what rate. Check that list before you start playing, as bets on excluded categories do not reduce the rollover balance.
