Casino / Slots
Every word on a game screen, odds board or account page has a specific meaning. This glossary covers the core terms across our slots, live casino tables, crash games, sports betting markets and your Nagad or Bank Transfer wallet — so you know exactly what you are looking at before you act.
These are the terms that appear most often across slot rooms and live tables. Understanding each one helps you read a game screen correctly and make a clear choice before you place any stake.
RTP stands for Return to Player. It is the percentage of total wagers a game pays back over a large number of rounds. A 96% RTP means the game returns 96 taka for every 100 wagered on average. We show RTP only where the game or studio exposes this figure in the lobby.
House edge is the casino's mathematical share of every wager, expressed as a percentage. It is the exact mirror of RTP carries a 4% house edge.
Volatility describes how a game distributes its prize rounds. High volatility slots pay less often but can deliver larger prizes when they do hit. Low volatility games pay more frequently but in smaller amounts. The setting is built into the game itself and is not adjusted by the platform.
Wager and turnover both refer to the total amount placed in bets. When a promotion condition states a turnover requirement, it means the total value of bets placed must reach that figure before a related balance becomes withdrawable. Your account dashboard shows the current turnover progress.
A jackpot is the top prize available in a specific game, awarded on a rare combination or trigger event. Some games carry a fixed jackpot built into their paytable; others carry a progressive jackpot that grows with each wager placed. The current jackpot value is shown inside the game itself.
A live dealer table streams a real human dealer operating physical cards, a roulette wheel or dice from a studio. You place bets on your screen while the deal happens in real time. Studios such as CQ9 and Habanero supply live table content accessible directly from the bdtk30 lobby.
These terms appear in the sports betting markets, payment flow and account verification screens. Reading them correctly helps you manage your stake size, understand your payout eligibility and complete wallet steps without confusion.
Asian handicap removes the draw outcome and gives one side a virtual head start. In cricket or football, a team may start at -1. 5 runs or goals. If your chosen side wins by more than the handicap, the bet settles in your favour. Half-line handicaps eliminate the possibility of a push result.
Over/under is a market on whether a measurable event — total runs in a cricket match, total goals in a football game — will finish above or below a set line. You back either side. There is no team preference involved; only the combined total matters for settlement of the bet.
Rollover is the number of times a given balance must be wagered before it qualifies for withdrawal. The figure is set by the applicable information condition. You can track your current rollover progress from the account dashboard after login; the exact status updates as you place bets.
An e-wallet is a digital account that holds a payment balance separate from a bank account. On bdtk30, the verified e-wallet options are Nagad and bKash. You link your registered mobile wallet number in the payment section of your account to enable deposits and withdrawals through either service.
KYC stands for Know Your Customer. It is a verification process where you confirm your identity by submitting documents the platform requests. Completing KYC unlocks full withdrawal access on your account. The documents required and the submission steps are shown inside the account verification section.
Decimal odds show the total return per unit staked, including the original stake. Fractional odds show profit only, expressed as a ratio. Our sportsbook defaults to decimal format. You can switch the display format from the odds settings within the sports section of your account.
These four term families cover different parts of the platform. Matching each group to where it appears helps you read screens faster without stopping to search.
RTP, volatility, bonus round, payline and multiplier appear on the game detail card or inside the game's information panel. For titles like Crash Drift or Baccarat Midnight, the key mechanic is shown in the game's own overlay before you place a stake.
Asian handicap, over/under, decimal odds and match lines appear in the sports betting section. Cricket markets — including BPL and international fixtures — use the same decimal format across all matches. Switch between markets using the category tabs at the top of the sportsbook screen.
Deposit, withdrawal, wallet balance, e-wallet and Bank Transfer appear in your account payment section. When you add Nagad or bKash as a payment method, the field labels use the same terms you see here. Your transaction history is listed in the wallet tab after each completed transfer.
Rollover, turnover, qualifying wager and minimum odds appear in the conditions attached to any information on your account. The current state of each condition is shown in your account dashboard after login, not in a general lobby notice. Check there to see what applies to your balance.
Knowing a term in isolation is only part of the picture. Where it gets useful is when several terms appear together on the same screen and you need to act quickly. Consider a slot session on a high-volatility title. The RTP figure — where the studio exposes it — sits in the game's information panel; the volatility label sits just below it.
In Crash Drift, the multiplier is the live figure that climbs until the round ends. The term 'cash out' appears as an active button; pressing it locks your multiplier at that moment. Understanding what multiplier means before the round starts removes hesitation at the key point.
Baccarat Midnight is a low house-edge table game. The three bet types — Player, Banker and Tie — each carry different house-edge values. The Banker bet carries a small commission deduction shown in the paytable; understanding house edge helps you weigh the commission against the statistical advantage.
When you open the deposit screen and select Nagad, the fields shown are: amount, Nagad account number and reference. The term 'minimum deposit' in this context refers to the floor amount the system will accept, displayed in the field itself. Enter the amount, verify the number and confirm.
If a KYC prompt appears when you attempt a Bank Transfer withdrawal, it means the account verification step has not yet been completed. The prompt links directly to the document upload section. Submitting the required documents there moves the withdrawal to the next processing stage.
Reading game and account language correctly changes how you browse the lobby. When you know that volatility describes payout rhythm rather than payout size, you can pick a slot that matches how long you plan to play — not just how large the prize looks on the thumbnail.
These questions are about where you find and act on the features these terms describe — separate from the definitions themselves.
Open the game's detail card in the lobby. Where the studio has published an RTP figure, it appears in the information panel on that card. Not every title exposes this figure — availability depends on what the provider such as JDB, Habanero or Spadegaming chooses to disclose in their game build.
Log into your account and open the dashboard. The current rollover status is shown there, updated after each qualifying wager. The target figure and the amount already counted are both displayed in the same panel so you can see how much is remaining before withdrawal eligibility activates.
Go to the payment section of your account. Select Nagad or bKash from the available wallet options and enter your registered mobile number. The method is saved to your account once verified. Subsequent withdrawals to that wallet use the saved number without requiring re-entry each time.
Open the account verification section from your profile menu. The document types required are listed there with upload fields for each. After you submit, the status changes from pending to under review and then to verified. The completed status unlocks full withdrawal access on your account.
Yes. Open the sports betting section and look for the odds format setting at the top of the page or in your account preferences. Select the format you prefer — decimal, fractional or American. The change applies across all open markets in the sportsbook immediately without needing to reload the page.
Open the deposit screen and select Bank Transfer as your method. The minimum and maximum amounts for that method are shown in the amount field before you enter a figure. These limits are set per payment method and are displayed at the point of transaction, not on a separate information page.
If a term in the game lobby, odds board or payment screen is not covered here, or if you see a label that does not match what this glossary describes, reach out through any of these channels. Our support team handles account, game and payment questions directly.
Open the chat widget from any page in your account. Describe the term or screen label you are unsure about and the support agent will walk you through what it means and where it appears in your specific account context.
Send a message to our support address with a screenshot or description of the term causing confusion. Email is well suited for questions about information conditions, rollover figures or KYC document requirements that need a written record of the response.
Your account dashboard includes a help section with labels and field descriptions for every payment and account step. Check there first for Nagad, bKash and Bank Transfer payment field explanations — most wallet and transaction terms are defined inline at the point where they appear.
