Slots / Casino
From RTP and volatility to Asian handicap and e-wallet verification, this glossary covers the language behind every game, bet, and account action on rollbet — so you can make informed decisions before you play.
Betting and casino platforms use a specific vocabulary that shapes every decision you make — from choosing a slot to placing a cricket wager. When you know what house edge means, you can compare game categories honestly. When you understand rollover, a information condition stops being a surprise. On rollbet, terms like RTP appear directly on game tiles where the provider exposes that data, and wallet language like e-wallet and KYC shows up at every account step. Reading this glossary once means you spend less time second-guessing and more time on the games and markets you actually came for.
Terms like RTP, volatility, house edge, and RNG appear on slot detail pages and live casino table information panels — wherever the game provider exposes that data. Check the info icon on any slot tile for the figures the studio has published.
Asian handicap, over/under, moneyline, and accumulator are the language of the sportsbook. You will see these labels on every cricket, football, and kabaddi market card when you open the sports section of the lobby.
E-wallet, deposit, withdrawal, and transaction history are the terms that run through your account dashboard. On rollbet, bKash and Rocket are the primary wallet rails — their names appear at the deposit and withdrawal screens exactly as you know them.
Rollover, wagering requirement, qualifying bet, and minimum odds are the conditions attached to any active information. These terms appear in the information detail panel; read them before you opt in so the requirement is clear from the start.
RTP stands for Return to Player. It is the percentage of total wagers a slot or game returns to players over a large number of rounds, as published by the provider. A higher RTP means a lower theoretical house margin on that title.
House edge is the mathematical advantage the platform holds on any game or market. It is the inverse of RTP for slots and is built into the odds on table games and sports markets. It does not predict individual session results.
Volatility describes how a slot distributes its payouts. High-volatility slots pay less often but in larger amounts. Low-volatility slots pay more frequently in smaller amounts. Neither is better — it depends on your session preference and stake size.
A wager or turnover is the total amount staked on qualifying games or markets. Information conditions often require a specific turnover amount before a gameplay becomes withdrawable. The qualifying games are listed in the information terms.
A jackpot is the highest prize pool available in a slot game, triggered by a specific in-game event or combination. The size and trigger conditions are set by the game provider and shown in the game's paytable or rules panel.
A live dealer game streams a real human dealer running a table game — baccarat, roulette, or blackjack — from a studio. You place bets through the interface while watching the action in real time, with results determined by physical cards or a wheel.
Asian handicap is a betting format used mainly in football and cricket that removes the draw outcome by giving one side a virtual head start. It narrows the market to two outcomes and typically offers tighter margins than a standard three-way market.
Over/under is a market where you bet on whether a measurable figure — total runs in a cricket innings, total goals in a match — will be above or below a line set by the sportsbook. The line and the odds are shown on the market card.
A rollover is the number of times you must stake a qualifying amount before a conditional balance can be withdrawn. For example, a stated rollover on a credited amount means you must wager that total across eligible games before withdrawal is available.
An e-wallet is a mobile-based payment account used to deposit and withdraw funds. On rollbet, bKash and Rocket are the supported e-wallet rails for Bangladesh. You link your registered mobile wallet number at the deposit screen to initiate a transfer.
KYC stands for Know Your Customer. It is the identity verification process required before withdrawals are processed. You submit identification documents through the account verification section; the status updates in your account dashboard once reviewed.
Session and account controls are settings that let you manage how you interact with the platform — such as reviewing transaction history, checking active information conditions, or contacting support. These are accessible from your signed-in account menu.
Knowing a term in isolation is useful; seeing how it connects to an actual screen is more useful. When you open a slot from PlayStar or PG Soft in the rollbet lobby, the game tile may show an RTP figure — that number comes directly from the provider and tells you the theoretical return rate for that title. A high-volatility label on the same tile tells you the payout pattern, not a promise. When you move to the sportsbook and open a cricket market for a BPL fixture, the Asian handicap tab sits alongside the standard match-winner market — the handicap line and the odds are both visible before you place anything.
On slots from PG Soft and PlayStar, the info panel on the game tile shows the RTP where the provider has published it. That figure is the provider's stated return rate — not a session guarantee.
Open any BPL or international cricket match in the sportsbook and select the handicap tab. The line and both-side odds are displayed on the market card before you confirm a stake.
If a information condition applies to your account, the remaining rollover amount is visible in the information section of your signed-in dashboard. Check it before switching game categories, as not all games may qualify.
Before a Rocket or bKash withdrawal is processed, your account verification status is shown at the withdrawal screen. If KYC is incomplete, the account section shows the documents still required.
If a term in the lobby, a information condition, or an account message is not clear, our support team can explain it. Use the channels published on the site — do not rely on third-party sources for account or payment guidance.
The live chat button is available from the main site navigation when you are signed in. Use it to ask about any term, account status, or lobby feature in real time.
For account-specific questions — including KYC status, transaction records, or information condition details — use the email address published on the Contact page of the site.
The Help Centre linked in the site footer covers common account, payment, and game questions with written answers. Search by keyword to find the relevant article before contacting support.
Open the slot and tap the information icon on the game tile or within the game interface. RTP is shown only where the provider has published it — not every title displays this figure, but those from PG Soft and PlayStar often do.
Sign in and go to the information section of your account dashboard. The remaining rollover amount and the qualifying game categories are listed there. Progress updates after each qualifying wager is settled.
Select bKash at the deposit screen, enter the amount within the limits shown, and follow the transfer steps to your registered bKash number. The transaction reference appears in your account wallet history once the deposit is confirmed.
The withdrawal screen will show your current verification status and list any documents still required. Submit them through the account verification section; once reviewed and approved, your withdrawal request can proceed normally.
Rocket is available as a payment rail on rollbet for supported Bangladesh account holders. The deposit and withdrawal screens both list Rocket alongside bKash. Check the limits and any instructions shown at the payment screen for your account.
Each information has a detail panel accessible from the information page. It lists the rollover requirement, qualifying games, minimum odds where applicable, and the period the condition covers. Read it before activating the information on your account.
