This glossary covers the words you encounter across our casino tables, slot rooms, sportsbook markets and account wallet — so each term means something clear before you make a decision.
When you open a game like Baccarat FireStorm or browse cricket handicap markets, the numbers and labels on screen carry specific meanings that affect how a round plays out. Knowing what house edge means tells you what the platform earns from each round on average.
The bd991 lobby groups features into casino, sportsbook, wallet and account sections. Each area has its own vocabulary. The four families below map a term type to the screen where you will read it so you can jump straight to the definition that matters right now.
Terms like RTP, volatility, house edge and RNG appear on game detail panels and provider information sheets inside slot and live table rooms. Check the individual game screen — not all titles expose RTP figures, only those where the studio publishes the value.
Asian handicap, over/under, decimal odds and spread all appear in the sportsbook section, most visibly on cricket match pages covering IPL and BPL fixtures. The odds format shown depends on your account display setting, which you can adjust in the account preferences panel.
Deposit, withdrawal, e-wallet, KYC and Bank Transfer appear in the cashier tab and during wallet verification. When you add Rocket or Upay as a payment method, the cashier screen walks you through the required account steps before a transaction is processed.
Rollover, turnover requirement, wagering contribution and minimum odds appear in the terms attached to any active information. Read these on the promo detail page — each offer lists its own conditions separately, so the rollover rate on one information may differ from another.
The six terms below come up most often when you are choosing between a live table and a slot room. Each definition is kept to the point — what the term means in the context of the lobby.
RTP stands for Return to Player. It is a percentage showing how much a game pays back on average over a large number of rounds.
House edge is the mathematical advantage the platform holds on each game, expressed as a percentage of every bet placed. It is the mirror of RTP carries a 4% house edge.
Volatility describes how often a slot pays out and in what size. High volatility means larger but less frequent payouts; low volatility means smaller but more regular ones.
A wager is a single bet placed on any game or market. Turnover is the total amount wagered over a period, often used to measure activity against a information condition. Your account history tab shows your cumulative turnover so you can track where you stand against any active information requirement.
In slots, a jackpot refers to the highest prize available within a game's feature structure. Some slots carry a fixed jackpot set by the studio; others use a pooled prize model.
A live dealer is a real person managing a physical table — cards, roulette wheel or dice — that is streamed directly to your device.
These six terms cover the sportsbook, cashier and account sections. They are distinct from the game mechanics above and appear most often when you are navigating payment steps or reading market odds on cricket fixtures.
Asian handicap is a betting format that removes the draw result by giving one team a virtual head start or deficit before the match begins. It is common in cricket and football markets.
Over/under is a market where you bet on whether a specific statistic — total runs, goals or corners — will be above or below a line set by the sportsbook.
Rollover is the number of times you must wager a qualifying amount before a gameplay becomes withdrawable. For example, a rollover requirement is stated in full on the information's own terms page.
An e-wallet is a mobile money account — such as Rocket or Upay — that you link to your bd991 cashier to move funds.
KYC stands for Know Your Customer. It is the identity verification process your account goes through to confirm your details match the payment method you use.
Decimal odds show your total return per unit staked, including the original stake. Odds of 2.50 mean a 100-unit bet returns 250 units total — 150 profit plus the 100 stake back.
Seeing a term in context makes it stick faster than reading a definition alone. When you open Spinner Star from the slot lobby, the information panel may show an RTP figure if PG Soft or the relevant studio has published one for that title — this is wher
When you tap the information icon inside Spinner Star or Bangladesh Night Spins 501, the game detail panel opens. If the studio has published an RTP figure, it appears there. If the panel shows no RTP, the studio has not released it — we do not generate or assume a number.
Open a BPL fixture in the sportsbook and locate the Asian handicap tab. The number next to each team is the virtual advantage or deficit applied before the match starts.
Every active information has a dedicated terms link. Click it to see the rollover multiplier, the eligible games and any minimum odds condition. Your account activity tracker — visible in the information tab once you are logged in — shows how much turnover you have accumulated against the requirement.
When you request a withdrawal via Bank Transfer, the cashier checks your KYC status first. If documents are pending, the screen shows what is needed and where to upload them. Completing verification unlocks the full withdrawal flow for Bank Transfer and other eligible routes shown in your cashier at that time.
If a definition here does not match what you see on a specific screen, reach out through the published support routes below. Our team can walk through the cashier step or game panel with you based on what your account currently shows.
The live chat icon is visible in the bottom corner of every lobby page once you are logged in. Start a conversation there to get a real-time explanation of any term, account step or cashier instruction you are unsure about.
Send a detailed question — including the screen name and the term you encountered — to the support email address published on the Contact page. Email is suitable for account-specific questions that need a written record, such as KYC document queries.
The Help Centre, linked in the footer, holds published articles covering cashier steps, information conditions and account verification. Search by term or category to find the article most relevant to the screen you are working through.
These questions focus on how you interact with the features the glossary terms describe — not the definitions themselves, but the practical steps inside your account.
Log in and open the Information tab. Select the active information to see a progress tracker showing how much of the required turnover you have completed. The tracker updates after each qualifying wager is settled, and it shows the remaining amount needed to meet the rollover condition.
Open the game from the lobby and tap the information or help icon — usually a small circle with an i — before starting a paid round.
Yes. Go to Account Settings and look for Display Preferences or Odds Format. You can switch between decimal and other formats supported on the platform. The change applies immediately across all sportsbook markets, including cricket and football, without requiring you to log out.
Open Account Settings and select Verification. The page shows which documents are required and their current status. Typical requirements include a national ID and a document matching your registered Bank Transfer account name. Upload the files shown on that screen and wait for the review notification in your account.
In the cashier, choose Rocket from the deposit method list. The screen displays the Rocket account number to send to, the minimum and maximum amounts, and a reference field.
Turnover contribution rates can differ between game types within a single information. The information's terms page lists the contribution percentage for each eligible category — slots, live casino and sportsbook may each carry a different rate. Check the terms before switching so you know how the activity counts toward the rollover target.
