Whether you are checking RTP on a slot or reading the rollover conditions on a information, every term you see in our lobby is explained here. Use this as a reference before you open an account or while you browse the catalog on any device.
When you know what a term means, you make faster decisions. You read a game card and spot the volatility label — you already know that means how often and how much a slot pays out in a session.
Terms like RTP, volatility, house edge and RNG appear on game cards and in the information panel each title shows before you start. Check these when you are choosing between a slot room and a table game in the catalog.
Asian handicap, over/under and spread are the language of the sportsbook, most visible on cricket and football markets. These appear in the bet slip and market listing each time you open a match in the sports section.
Deposit, withdrawal, rollover, KYC and e-wallet all appear in your account area and on the cashier screen. bKash, Upay and Bank Transfer are the payment rails you will see named there for supported Bangladesh regions.
Wagering requirement, turnover and qualifying bet are the terms that govern what your account must do before a promotional balance can be withdrawn. These appear in the conditions panel linked from any active information notice.
These are the six terms you will encounter most often when browsing slots, live tables and crash games in the catalog.
RTP stands for Return to Player. It is the percentage of total bets a game is designed to pay back over a large number of rounds.
House edge is the mathematical advantage the game holds over the player across all bets. It is the inverse of RTP carries a 3% house edge. Every casino game has one built in, and it determines the long-run odds structure.
Volatility describes how a slot distributes its payouts. High-volatility slots pay less often but in larger amounts when they do hit. Low-volatility slots pay smaller amounts more regularly. Volatility affects session length planning more than it affects the overall RTP figure.
A wager or turnover requirement is the total bet amount your account must reach before a bonus balance qualifies for withdrawal. For example, a turnover condition requires you to place bets totaling a set multiple of the bonus amount through real game rounds.
A jackpot is the largest prize tier in a slot or prize-style game. A fixed jackpot pays a set amount; a progressive jackpot grows with each qualifying bet across connected games until one round triggers the top prize. Prize structure details are shown in each game's information panel.
A live dealer game streams a real human dealer from a studio to your screen. You place bets through the interface while the dealer manages cards or a wheel in real time.
These terms appear in the sportsbook, cashier and account verification sections — distinct from the game-mechanics vocabulary above.
Asian handicap is a betting format used mostly in football and cricket that removes the draw outcome by giving one side a virtual head start or deficit. It splits bets across two outcomes rather than three, which changes the odds calculation compared with standard match betting.
Over/under is a market where you bet on whether a measurable total — runs scored, goals, points — will finish above or below a line the market sets. In cricket it commonly appears on run totals per over or for the full innings across BPL and international matches.
Rollover is another word for wagering or turnover requirement. It specifies the total bet volume your account must complete before a promotional balance is eligible for withdrawal. The rollover amount and qualifying games are listed in the conditions panel of each information.
An e-wallet is a digital payment account that stores funds for online transactions. bKash, Upay and Nagad are the e-wallet options used most by players in Bangladesh. You link your e-wallet to your vb87 account on the cashier screen to deposit or withdraw through that rail.
KYC stands for Know Your Customer. It is an identity verification process where you submit documents confirming who you are. Your account may require KYC completion before certain withdrawal amounts are processed. The documents and steps required are shown in the account verification section.
Responsible-play limits are account controls that let you set boundaries on session activity, such as deposit amounts or session durations. These settings are managed in the account area. The specific options available depend on the platform configuration shown in your account at the time of use.
Seeing these terms in isolation is one thing; knowing where they appear in an actual session is more useful. When you open Roulette Nightfire in the live casino section, the game card shows a table limit range before you jo
When you join Roulette Nightfire or Holdem QuickSpin, the pre-join screen shows minimum and maximum bet limits. These are the table limits — not the house edge, which is a separate figure in the game rules panel.
Crash Dice Roller and similar titles show RTP only when the studio that built them exposes it. Where RTP is not shown, the panel still lists volatility as a general label — high, medium or low — to help you read the session pattern.
Cricket Tips Section and Football Bet Zone surface over/under and handicap markets in the bet slip once you select a match. The line for each market updates with the market; the terms in this glossary explain the structure behind those numbers.
Your account's cashier screen labels each transaction by payment method — bKash, Upay or Bank Transfer — and by status. KYC prompts appear on this screen if your account requires verification before a withdrawal of a certain amount proceeds.
If a term in the lobby or a condition in your account is not clear, our support team can walk you through what it means in context of your specific account activity.
Open the chat widget from any page in the lobby to reach the support team directly. Available through the help icon on the bottom right of the screen on both mobile and desktop.
Send a message to the support address listed on the Contact page. Include the term or feature name and the section of the lobby where you saw it, and the team will respond to your registered account email.
The Help section inside your signed-in account area covers common term queries, cashier steps and account verification. Check there first for answers about KYC, deposit rails and information conditions.
These questions cover how the terms above work when you are actually using the catalog, cashier or account area on vb87.
Open the game card for the slot you want and look for the information or details tab before you start a round. vb87 displays RTP only where the studio behind that title exposes it — not every title shows this figure.
Each information notice in your account area includes a conditions link. Open it to see the rollover multiple, the qualifying game categories and any time limit that applies. Read this before starting sessions you intend to count toward the requirement.
A pending KYC status means your account needs identity verification before that withdrawal is processed. Open the account verification section, follow the document steps shown there, and the cashier screen will update once the check is complete.
Payment method options for withdrawal are shown in your account cashier. Some accounts are set up to return funds to the same rail used for the deposit. Check the withdrawal screen in your signed-in account for the options available to your account specifically.
A fixed jackpot pays the same set amount every time it is triggered, regardless of how many rounds have been played. A progressive jackpot grows over time as qualifying bets are placed, then resets after a round triggers the top prize. Each game's information panel shows which type applies.
Live dealer tables stream a real dealer to your screen and run on a fixed schedule, so seat availability and bet windows are time-bound.
