Live / Slots
From RTP on a slot screen to rollover on a wallet transaction, this glossary covers the language of the lobby so you can make account decisions with confidence. We have organised definitions across game mechanics, odds, payments and account conditions.
Knowing what a term means changes how you use the platform. When you see volatility listed on a slot from or , that single word tells you how often the game pays and in what size — information that shapes which title you open first.
Four groups of terms cover almost everything you encounter across the 87b1 lobby, sportsbook and account pages. Knowing which family a term belongs to tells you where to look for it.
Terms like RTP, volatility, RNG and house edge appear on slot detail pages and live casino table information panels. Providers such as and surface these where the game rules are shown.
Asian handicap, over/under, decimal odds and spread sit inside the sportsbook market view. Cricket markets — IPL, BPL and international fixtures — use these formats most visibly in the Bangladesh lobby.
Deposit, withdrawal, e-wallet, minimum transaction and processing status are the terms on your account funding screen. bKash and Bank Transfer each have their own flow, and the labels on those screens follow this vocabulary.
KYC, rollover, turnover, wagering requirement and eligibility appear in the account verification section and on any active information detail page. Read these before confirming a transaction or accepting a condition.
These are the six terms that appear most often across slot lobbies and live casino tables. Each definition is written to match the way the term is used on screen.
RTP stands for Return to Player. It is the percentage of total wagers a game returns to players over a large number of rounds.
House edge is the mathematical advantage the platform holds on a game over time. It is the complement of RTP on slots and a built-in margin on table games. A lower house edge means the gap between your wager and the expected return is smaller over many rounds.
Volatility describes how a slot distributes its payouts. High volatility means fewer wins but larger amounts when they land. Low volatility means more frequent smaller wins. The term appears on game detail pages for titles from studios like and .
A wager or turnover requirement is the total amount of play needed before a balance or condition is met. If your account shows a turnover figure, that is the cumulative bet total required. Check the account conditions page for the exact calculation method applied.
In slot mechanics, a jackpot refers to the highest prize tier a game offers, triggered by a specific symbol combination or feature round. The size and trigger conditions vary by title. RTP information for jackpot slots is shown only where the provider exposes it.
A live dealer game streams a real human dealer running a table — baccarat, roulette or blackjack — from a studio. You place bets through the interface while watching the dealer in real time. Live dealer tables are available in the casino section of the 87b1 lobby.
These six terms cover the sportsbook, your payment flow and account verification. They come up at the point of a transaction or when you are reading a market.
Asian handicap is a betting format that removes the draw outcome by giving one side a head start in goals or runs. It is common in cricket and football markets. The handicap is shown as a positive or negative number next to the team name in the sportsbook market view.
Over/under is a market where you predict whether a measurable figure — total runs, total goals — will be above or below a set line. The line is set by the market and shown alongside the odds. It is one of the most used formats in BPL and international cricket betting.
Rollover is the number of times a specific balance must be wagered before it qualifies for withdrawal or before a condition clears. The rollover multiplier and the eligible games or markets are stated in the account or information conditions section.
An e-wallet is a mobile or digital account that holds funds for transactions without requiring a bank card each time. bKash is the primary e-wallet route on 87b1 for Bangladesh. Deposits and withdrawals through bKash follow the steps shown in the payment section of your account.
KYC stands for Know Your Customer. It is the identity verification process your account goes through before withdrawals are processed. The documents required and the submission steps are shown in the verification section of your account page. Complete this early to avoid delays.
Account controls let you set boundaries on your own activity — session reminders, cooling-off periods or account pauses. These are managed from the account settings page. The options available depend on the platform configuration shown in your account at the time of access.
Terms rarely appear alone. When you open a slot from or , the game detail panel may show RTP alongside volatility — those two figures together tell you the payout frequency and the size distribution in one read.
RTP and volatility appear together on the information screen for titles from , and . Read both before opening a session to understand payout frequency and size distribution.
Asian handicap lines and over/under totals sit side by side in cricket and football markets. The decimal odds next to each selection show the return per unit. BPL and international cricket fixtures use both formats regularly.
The deposit screen for bKash shows a minimum transaction amount and a processing status field. The status vocabulary — pending, confirmed, failed — matches the payment terms in this glossary.
Rollover and KYC status are both visible on the account page. KYC must be complete before a withdrawal is processed; rollover shows the remaining wagering activity required before a balance condition clears.
If a term on screen is unclear or a definition here does not match what you are seeing in your account, reach out through the support routes published on the site. We can walk through what a specific label means in the context of your account.
Open the chat widget from any page in the lobby. Describe the term or screen you are looking at and the support team will clarify it in the context of your account.
Send a message through the contact form on the support page. Include a screenshot or the section name where you saw the term for a faster, more specific reply.
The help centre on the site covers common account and payment questions with step-by-step explanations. Search the term directly to find the relevant article.
These questions are about how the platform works in practice — not definitions, but the actions and screens where these terms become relevant.
Open the game detail panel before launching the title. If the provider has made RTP available, it appears there. Not every studio exposes this figure; where it is absent, the provider has not published it for that title.
Go to the verification section of your account page. The documents required and the upload steps are listed there. Submit early — KYC must be complete before any withdrawal is processed, so doing it at account setup avoids delays later.
Select bKash on the deposit screen, enter the amount within the limits shown, and follow the steps displayed. The transaction status updates on your account page once the payment is confirmed on the bKash side.
It is the cumulative bet total required before a balance condition clears. The figure counts down as you place wagers on eligible games or markets. The account conditions page shows which games and markets count toward the total.
Yes. Bank Transfer is available as an alternative route for larger transactions. Select it on the deposit or withdrawal screen and follow the account and bank details shown. Processing follows the steps and limits displayed at the time of the transaction.
Open the sportsbook section and select cricket. BPL and international fixtures list available markets including Asian handicap lines. The handicap value and decimal odds for each selection are shown directly in the market row.
