This glossary covers the words and abbreviations you encounter across the gb8 lobby — from game-mechanic labels like RTP and volatility to account and payment language like KYC and e-wallet.
When you scan a slot description and see a volatility label or a turnover condition attached to a promotional offer, the words are doing real work.
Terms cluster naturally around the four areas you use most. Knowing which family a word belongs to tells you where on screen to look for its value or setting — paytable, odds column, wallet page or account panel.
Labels like RTP, volatility, paylines and multiplier appear on individual game paytables and in lobby filters. JDB, PlayStar, PG Soft and Joker each display these where the provider has published them — if a figure is absent, it has not been released.
Terms like Asian handicap, over/under, decimal odds and spread belong to the sportsbook section. You see them in the market column next to each fixture — cricket matches, BPL games and international events use the same format throughout the lobby.
E-wallet, deposit, withdrawal, minimum transfer and transaction ID appear on the Cashier page and in your transaction history. bKash and Bank Transfer are the verified payment rails; the Cashier page shows current limits and required reference fields for each route.
KYC, verification, rollover, turnover requirement and conditional balance are visible in account settings and on any information detail panel. Read the conditions panel on each offer before confirming — it lists the exact rollover multiplier and eligible game types.
These are the six words that appear most often in slot and live casino screens. Each definition covers what the term actually means — not a promotional interpretation.
RTP is the theoretical percentage of total wagers a game returns to players over a very large number of rounds. It is a statistical average across millions of spins, not a promise for any single session or player.
House edge is the mathematical advantage the game design holds over the player, expressed as a percentage of each wager. A lower house edge means the game retains a smaller share of total bets over time, on average.
Volatility describes how frequently a slot pays out and in what size. High-volatility games pay less often but can produce larger single wins. Low-volatility games pay more regularly but typically in smaller amounts per round.
A wager or turnover requirement is the total amount you must stake before a conditional balance becomes withdrawable. It is expressed as a multiplier — for example, a 10x requirement on a 500 balance means staking 5,000 in eligible games.
A jackpot is the largest prize pool available in a specific slot or game feature. Fixed jackpots pay a set amount; progressive jackpots accumulate from a portion of each bet placed across eligible rounds until one player wins the full pool.
A live dealer game streams a real human dealer conducting the game — dealing cards or spinning a roulette wheel — from a studio camera feed. You place bets through on-screen controls while watching the dealer's actions in real time.
These six terms come up specifically in the sportsbook, cashier and account verification areas. They are distinct from the game-mechanic words above.
Asian handicap removes the draw outcome and assigns a run or wicket head-start to the underdog team. It narrows the market to two outcomes, which typically adjusts the available odds compared to a standard three-way match result market.
Over/under is a market where you predict whether a measured value — total runs, total goals, total corners — will finish above or below a line the sportsbook sets. You do not pick a winner; only the final count against the line determines the result.
Rollover is the number of times a specific balance amount must be staked before withdrawal eligibility unlocks. It is the same concept as a turnover requirement, and the exact multiplier is stated on the individual offer's conditions panel in your account.
An e-wallet is a digital account that holds funds separately from a bank account, used to deposit and withdraw. bKash operates as an e-wallet on gb8 — you send from your bKash number to the displayed merchant reference, then confirm in your gb8 cashier.
KYC stands for Know Your Customer. It is the identity verification process where you submit documents — typically a national ID — so the platform can confirm account ownership. KYC is required before withdrawals are processed on verified accounts.
Decimal odds show your total return per unit staked, including your original stake. Odds of 2.50 on a 100 bet return 250 if the selection wins — 150 profit plus your 100 back. It is the format used across the gb8 sportsbook by default.
Terms do not appear in isolation — they stack together when you make a real decision in the lobby. Consider opening Jamuna King Slots: the paytable shows the volatility rating and, where the provider has published it, the RTP figure sits directly
Open the game info panel inside Jamuna King Slots to see its volatility tier. RTP is shown only where the studio has published it. Both figures are on the paytable screen, not the lobby thumbnail.
In the cricket sportsbook, the Asian handicap column sits beside the match result column. Select the handicap tab to see adjusted odds for each team, with the run-line displayed next to each selection.
After sending a bKash deposit, copy the transaction ID from your bKash message. Paste it into the reference field on the gb8 cashier page. Your transaction history updates once the deposit is confirmed on both sides.
If your account shows a conditional balance, open the information detail in your account area. The rollover multiplier, eligible categories and expiry date are all listed there — read each field before placing a bet against that balance.
If a definition in this glossary does not match what you see on screen — a field label, a cashier message or an odds format — reach out through the published support routes below. Our team can clarify what a specific lobby label means in your account context.
The live chat icon is visible on every page when support is available. Open it and describe the term or screen label you need explained — the support team can pull up your account context directly during the conversation.
Send a message to the support email address listed on the Contact page. Include the term you are asking about and, where relevant, a screenshot of the screen where it appeared. Email suits detailed questions about transaction records or account verification labels.
The Help Centre, accessible from the footer, contains published articles on payment steps, account verification and game-mechanic labels. Search the term directly — many cashier and bKash-specific questions already have a dedicated answer page there.
These questions are about how you interact with the features — not just what the words mean.
Open the game's info or paytable panel inside the slot itself. RTP is displayed only where the studio — JDB, PlayStar, PG Soft or Joker — has published it. If the figure is absent, the provider has not released it publicly.
Go to your account area and open the information detail. The panel shows how much of the rollover requirement you have completed, the eligible game types that count toward it, and the remaining amount still needed before the balance unlocks.
After sending funds from your bKash wallet, the app generates a transaction ID in the confirmation message. Copy that ID and enter it in the reference field on the gb8 cashier page. It links your bKash payment to your account deposit record.
The handicap line adjusts the effective match result. If you back a team with a minus handicap, they must win by more than that margin for your bet to succee
KYC verification confirms that the account belongs to you before funds leave the platform. You submit identity documents through the verification section in your account settings. Withdrawals — whether to a bank account or via Bank Transfer — are processed after the verification step clears.
The sportsbook defaults to decimal odds, which show your total return per unit staked. Check your account preferences or the sportsbook settings tab to see whether additional formats are available for your account region and access level.
