This glossary covers the words you see across our sportsbook, live casino tables and account wallet — from RTP and volatility to rollover and KYC. When a term is clear, every decision from choosing a game to moving funds through Nagad becomes faster and more confident.
Every screen in the 669a lobby carries a word or short phrase that shapes how a round works or how your account balance moves.
The 669a lobby groups its features across four functional zones, and each zone has its own vocabulary. Recognising which family a term belongs to tells you where to look for it on screen and what action it relates to.
Terms like RTP, volatility, paylines and multiplier live inside individual game pages and provider detail panels. You see them when you open a slot title or check the information tab on Rocket Payout Track or River Padma Reels before committing a stake.
Asian handicap, over/under, decimal odds and match result appear in the sportsbook section. Cricket Score Chase and Football Straight Bets display these terms next to each market line, so reading them correctly changes how you interpret the price shown.
E-wallet, Bank Transfer, KYC and account balance are the terms on the deposit, withdrawal and verification screens. When you fund your account via Nagad or Bank Transfer, the confirmation screen uses this vocabulary to describe the status of each transaction step.
Rollover, turnover, wagering requirement and minimum odds are the words attached to any credited amount shown in your account. They define what action is needed before a promotional balance becomes withdrawable, and they appear in the terms linked from each notice.
The six terms below appear most frequently across slot lobbies, live tables and information panels. Each definition is written for plain reading, not technical instruction.
RTP stands for Return to Player. It is a percentage showing how much of all wagered amounts a game is designed to return over a statistically large number of rounds. It does not predict individual session results. 669a displays RTP only where the game or studio exposes it.
House edge is the mathematical advantage the platform holds over a player across all rounds of a game. A lower house edge means the game's built-in advantage is smaller. It is the inverse of RTP and applies to table games and live dealer rounds as well as slots.
Volatility describes how a slot distributes its payouts. High volatility means wins arrive less often but can be larger when they land. Low volatility means more frequent, smaller wins.
A wager or turnover requirement is the total amount you must stake before a promotional balance can be withdrawn. It is always expressed as a multiplier of the credited amount. The exact figure is shown in the terms attached to each information notice in your account area.
A jackpot is the highest prize pool or payout level within a slot game's own feature structure.
Live dealer describes a casino table — such as Sylhet Roulette Room or Dragon Tiger Fast Table — streamed from a studio with a real human dealer managing the cards or wheel.
The six terms below cover the sportsbook, payment workflow and account verification screens. They are distinct from the game-mechanics terms above and appear in different parts of the platform.
Asian handicap is a sports betting market format that removes the draw outcome by giving one team a head start or deficit in goals or runs before the match begins.
Over/under is a market where you predict whether a measurable match statistic — total runs, goals or corners — will finish above or below a number set by the sportsbook.
Rollover is another word for wagering or turnover requirement. It specifies how many times a credited balance must be staked across eligible markets or games before withdrawal is possible. The rollover multiplier and eligible game types are always listed in the terms linked from your account notification.
An e-wallet is a mobile-based payment account — such as Nagad or bKash — that holds a balance you can use to fund your 669a account without entering bank card details each time. Transfers are initiated from the e-wallet app and confirmed on your account deposit screen.
KYC stands for Know Your Customer. It is the identity verification process the platform uses to confirm your details before processing a withdrawal or when prompted by account security checks. You complete it by submitting the documents listed on the verification screen inside your account settings.
Decimal odds show the total return per unit staked, including your original stake. An odd of 2.50 means a one-unit stake returns 2.50 units if the selection wins — so 1.50 units is profit.
Opening the Rocket Payout Track game page shows two terms side by side in the information tab: RTP and volatility.
Both appear in the information tab of slot titles like Rocket Payout Track and River Padma Reels. RTP is the long-run return percentage; volatility tells you how evenly that return is distributed across rounds.
Live dealer tables display house edge in the game rules panel. Dragon Tiger Fast Table has a straightforward two-card structure, so the edge figure is easy to find and compare against other table options in the live casino section.
The over/under line in Cricket Score Chase sits next to the match result and Asian handicap options. It is the most literal market on the board: pick a side of the number, confirm your stake, and the result is settled when the innings closes.
After a Nagad deposit triggers a credited amount, the account notification links directly to the terms. The rollover multiplier, minimum odds and expiry date are all there — no need to calculate anything yourself, just read the fields the platform exposes.
If a definition here does not match what you see on a specific screen, or a term appears in your account in a context that is not covered above, these are the routes we publish for getting a direct answer.
The live chat icon sits in the lower corner of the 669a interface. Open it, describe the term or screen you have a question about, and a support agent will clarify what it means in that specific account or game context.
For questions about information terms, KYC documents or wallet transaction labels, email the support address listed in the Help section of your account. Include a screenshot of the term in question for the fastest resolution.
The Help section inside your signed-in account contains published explanations of deposit, withdrawal and verification terms. These pages are updated when platform conditions change, so they reflect the current wording you see on your own screens.
These questions focus on how the platform features behind each term actually work — distinct from the definitions themselves.
Open the game page and look for the information or details tab — usually a small icon inside the game frame or on the lobby card.
Go to your account settings and open the verification section. The screen lists the documents required and the upload fields. Submit what is listed there and follow the confirmation steps shown. Support via live chat can clarify which document type is needed if the screen is not clear.
Nagad appears as a payment option on both the deposit and withdrawal screens where it is available for your account. Availability depends on your account status and eligible region. Check the payment screen inside your signed-in account for the current options shown for your profile.
A notification appears in your account inbox or the information tab after a credited amount is applied.
Your account session carries across the sportsbook, live casino and slot lobby without requiring a fresh login.
Handicap-style markets do appear in cricket alongside standard match result and over/under lines. The exact market types available for a given match depend on the fixture and when it is listed. Open Cricket Score Chase in the sportsbook section to see which market formats are active for upcoming matches.
