From RTP on slot screens to rollover conditions on the information board, the ak57 glossary gives you a plain-language definition for every term that comes up as you move through the lobby, manage your account wallet, or fund your session via bKas
Knowing what a term means before you act on it changes the decision you make. When a slot screen shows a volatility rating, or a sportsbook market labels a line as Asian Handicap, or your acc
Every term on this page belongs to one of four practical families. Knowing the family tells you which screen or account step the term is describing, so you can find the right definition without scanning the full list every time.
Terms like RTP, volatility, house edge, RNG and payline appear on individual game screens, in game-info panels, and on studio-provided rule cards inside the lobby. Check the info icon on any slot or table game to see which of these figures the provider has published.
Terms like Asian Handicap, over/under, decimal odds and spread appear in the sportsbook section. Cricket markets — including BPL and international fixtures — use these labels on every event card, so recognising them before you place a stake saves time and avoids misreading a line.
Terms like e-wallet, deposit reference, rollover, turnover, KYC and transaction ID appear in the cashier section, your account dashboard, and on bKash or Nagad transfer confirmation screens. Your wallet balance and any pending account step will reference these terms directly.
Terms like wagering requirement, qualifying stake, expiry and minimum odds appear in the conditions attached to any active information. Read the specific published terms for each offer in the information section of your account — this glossary defines the term shape; the information supplies the numbers.
These are the terms you will encounter most often on slot screens, live dealer tables, and game info panels inside the lobby.
RTP stands for Return to Player. It is a percentage that describes how much of total stakes a game pays back over a very large number of rounds. A higher RTP means less held by the house mathematically, though individual sessions vary widely.
House edge is the mathematical advantage the game operator holds over time, expressed as a percentage of each stake. It is essentially the inverse of RTP.
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 smaller, more frequent wins. Game providers set this at the design stage; it appears in the game info panel where the studio chooses to publish it.
A wagering or turnover requirement states how many times a qualifying amount must be staked before a related balance becomes withdrawable. For example, a ten-times requirement on a deposit means staking that deposit amount ten times across qualifying games. The exact multiplier is always stated in the specific information terms.
A jackpot is the highest available prize within a slot game's structure. Some slots carry a fixed jackpot set at the game design stage; others link across multiple players to build a shared prize pool.
A live dealer game streams a real human dealer operating physical equipment — cards, roulette wheel, or dice — from a studio. You place bets through your screen in real time. In the ak57 lobby, live dealer tables include Baccarat StarLight and are supplied by the studios configured on this platform.
These terms appear most in the sportsbook, cashier, and account verification sections of the platform.
Asian Handicap removes the draw outcome by giving one side a fractional or whole goal advantage before the match starts. It narrows betting to two outcomes, which adjusts the odds compared to a standard three-way market. Cricket and football matches in the sportsbook section both use this format on selected markets.
Over/under is a market where you predict whether a measurable figure — total runs, total goals, total corners — will finish above or below a line set by the platform.
Rollover and wagering requirement refer to the same mechanic: staking a balance a set number of times before withdrawal is permitted.
An e-wallet is a mobile-based payment account — such as bKash or Nagad — that holds funds separately from a bank account and allows transfers via a mobile number.
KYC stands for Know Your Customer. It refers to the identity and account verification steps a platform requires before processing certain transactions or releasing funds.
A transaction reference is the unique identifier generated when you complete a bKash or Nagad transfer to fund your account. It appears in your mobile wallet's confirmation message and in the ak57 cashier history.
Terms rarely appear in isolation. When you open Slot Heroes in the lobby, the game info panel may show both an RTP figure and a volatility rating side by side — knowing both at once tells you whether the game is designed for frequent smaller returns
Open any slot in the lobby — such as Slot Heroes or Crash SpinWin — and tap the info or rules icon.
On a cricket event card in the sportsbook section, the market labels — over/under, Asian Handicap, decimal odds — appear directly on the selection row. Hover or tap a market name to see the full conditions. BPL and international cricket fixtures use these same label formats across every listed event.
When you initiate a bKash or Nagad deposit in the cashier, the screen shows a reference field and a transfer destination.
Any KYC prompt or wagering-requirement notice from an active information appears as a flagged item on your account dashboard. The notice states the specific step or remaining turnover balance. Check this screen after each session to see whether a pending condition has been partially cleared by recent activity in the lobby.
If a term on your account screen or in a information notice is not covered here, or if the definition here does not match what you are seeing in a specific game or cashier step, reach out through the published support routes below.
The live chat widget is accessible from any page within your logged-in account. Use it to ask about a specific term as it appears on your screen, or to flag a cashier field you do not recognise. Have your account ID available when you open the chat.
For detailed term clarifications tied to a specific transaction or information, email support allows you to attach a screenshot of the screen showing the term in question. The support address is published in the Help or Contact section of your account area.
The Help Centre within your account area contains published articles on cashier steps, bKash and Nagad deposit flows, and account verification. Search the term you want to clarify there first — many account and payment terms have dedicated articles with step-by-step context.
These questions cover how specific features work on ak57 — going beyond the definition to how you actually interact with them in your account.
Open the game from the lobby and look for an info, rules, or paytable icon — usually a small i or question mark on the game frame. The studio publishes RTP there if the figure is made available.
If an active information has attached a wagering requirement to your balance, the cashier will show a remaining turnover amount before the related funds are withdrawable.
An incorrect reference means the platform cannot match your incoming transfer to your account, so your balance will not update automatically. Contact support via live chat with your correct bKash transaction ID and the transfer amount. The team will trace the payment against the cashier record and resolve the mismatch manually.
Cricket markets in the sportsbook section include Asian Handicap lines on selected matches, including BPL and international fixtures.
Go to your account settings or verification section — the dashboard notice will link directly to the flagged step.
Your account cashier or transaction history section logs every deposit and withdrawal, including Nagad transfers, with the date, amount and reference number for each entry. Filter by payment method if the section provides that option.
