This glossary covers the terms that appear across our game rooms, account wallet, and betting markets — so you know exactly what each label means before you act on it. Availability depends on your local law and eligible regions.
When you open a slot or sit at a live table, the numbers and labels on screen carry real meaning. RTP tells you the theoretical return rate a game is built around.
Our lobby organises terms into four practical families depending on where you encounter them.
Terms like RTP, volatility, house edge, and RNG appear on individual game tiles and in provider detail panels. They describe how a game is built, not what will happen in your next session.
Asian handicap, over/under, and decimal odds appear in the sportsbook section, most visibly on cricket and football markets. Each format has its own way of expressing probability and potential return.
Deposit, withdrawal, rollover, and KYC labels appear in your signed-in account area. These terms govern how money moves between your Nagad, Rocket, or Bank Transfer source and your 66b2 wallet balance.
Turnover requirement, wagering condition, and eligible games are the terms attached to any active information. They appear in the information detail screen inside your account and define what qualifies a round toward the stated condition.
Plain definitions for the terms you will see most often across our slot rooms and live tables.
RTP stands for Return to Player. It is the percentage of all wagered amounts a game is designed to pay back over a very large number of rounds. A game showing 96% RTP is built to return 96 units for every 100 wagered across its full statistical cycle. Individual sessions vary widely from this figure.
House edge is the mathematical advantage the game holds over the player, expressed as a percentage of each wager. It is the complement of RTP carries a 4% house edge. Table games like blackjack typically carry a lower house edge than many slot titles.
Volatility describes how a slot distributes its payouts. High-volatility games pay less often but in larger amounts when they do hit. Low-volatility games pay more frequently in smaller amounts. Neither is better — it depends on your session preference and available balance.
A wager or turnover is the total amount staked across qualifying rounds. Information conditions often require a specific turnover amount before a balance becomes withdrawable. The exact multiplier and eligible games are listed in the information detail screen inside your account.
In slot context, a jackpot refers to the highest prize tier a game offers, triggered by a specific symbol combination or bonus feature. Some titles carry a fixed jackpot amount; others accumulate across rounds. The game's own paytable shows the current structure.
A live dealer game streams a real human dealer from a studio to your screen in real time. You place bets through the interface while watching the dealer handle physical cards or a roulette wheel. Live tables at 66b2 include baccarat, roulette, and blackjack formats from our studio partners.
Definitions for the terms that appear in the sportsbook, your wallet, and the account verification flow.
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 adjusts the odds accordingly. Quarter and half-ball lines are common variants you will see in our cricket markets.
Over/under is a market where you predict whether a measurable figure — total runs in a cricket innings, total goals in a match — will finish above or below a line set by the sportsbook. The line and the odds for each side are shown on the market card before you place a stake.
Rollover is the number of times a bonus or deposited amount must be wagered before it can be withdrawn. A rollover of five times on a 500-taka balance means 2,500 taka in qualifying wagers must be completed. The specific multiplier for any active information is shown in your account's information detail screen.
An e-wallet here refers to a mobile-based payment account — Nagad or Rocket — that you link to your 66b2 deposit and withdrawal flow. Transactions move between your mobile wallet and your 66b2 account balance. Bank Transfer is also available for those who prefer direct bank routing.
KYC stands for Know Your Customer. It is the identity verification step your account may require before a withdrawal is processed. You submit identification documents through the verification section of your account. The exact documents required are listed in the verification screen itself.
These are account-level tools that let you set limits on your own activity — session time, deposit amounts, or a cooling-off period. They are accessible from your account settings. Using them is your choice; the controls are there whenever you want them.
Knowing a definition is one thing; seeing where it appears in the lobby is another. When you open Slot ThunderSpin, the game tile shows an RTP figure — that number comes from the provider and is displayed only where the studi
The RTP figure on a slot tile is set by the studio, not by 66b2. It reflects the game's long-run statistical design. Check the game's own info panel for the figure where the provider has made it available.
An Asian handicap line on a cricket match adjusts the effective margin of victory. The market card shows the line and both-side odds before you confirm a stake — read both before deciding which side fits your view of the match.
After each qualifying wager, the rollover counter in your information detail screen updates. You do not need to calculate it manually — the screen shows remaining turnover required against the current balance.
If your account shows a KYC pending banner, the verification screen lists exactly which documents are needed. Submitting them through that screen is the step that clears the withdrawal path.
If a term in the lobby or your account screen is not covered here, our support team can clarify it directly.
Open the chat widget from any page while signed in. Describe the term or screen you are looking at and our team will explain what it means in your account context.
Send your question to our published support address. Include a screenshot of the screen where the term appears if that helps describe the context. We respond through the same channel.
Our help centre contains articles on account steps, wallet actions, and game mechanics. Search the term directly in the help centre search bar to find the relevant article.
Questions about how the features these terms describe actually work inside your 66b2 account.
RTP is shown on the game's own information panel where the studio has published it. Open the game tile, look for the info or details option, and the figure appears there if available. Not every title displays it — that depends on what the provider exposes.
Sign in and open the information section of your account. Each active information shows a detail screen with the current rollover counter, the qualifying wager total so far, and the remaining amount needed before the balance is withdrawable.
Yes. Deposits made via Nagad, Rocket, or Bank Transfer all count toward your account balance in the same way. Rollover conditions apply to wagers placed from that balance, not to the deposit method itself. Check the information detail screen for any method-specific notes.
A pending KYC status will hold the withdrawal until verification is complete. Your account header shows the pending banner, and the verification screen lists the documents needed. Submit them there and the withdrawal request can proceed once the check clears.
For a shorter session with a fixed balance, lower-volatility slots tend to extend play because payouts come more frequently in smaller amounts. Higher-volatility titles can go many rounds without a significant return. The game's paytable structure gives you a signal even when volatility is not labelled directly.
Open the information detail screen inside your signed-in account. The eligible games list is shown there alongside the turnover multiplier and any other conditions. If a game you want to play is not on the list, rounds in that title will not count toward the rollover requirement.
