The bd ok Glossary: Every Term You Will See in the Lobby
From RTP and volatility on the slots screen to rollover conditions in your account area, this glossary covers the language you encounter across the lobby, payment panel and live tables — so you can make confident decisions rather than guessing.
Every screen in the lobby uses a specific vocabulary. When the game card shows volatility or the deposit panel mentions a rollover requirement, those words directly affect which title you pick and how you manage your wallet balance.
FOUR TERM FAMILIES
Where Each Term Group Appears in the Lobby
The glossary splits into four practical families so you can find the right definition at the right moment. Each family maps to a specific part of what you see on screen — from the game tile to the cashier panel.
Game Mechanics
Terms like RTP, house edge, volatility, payline and multiplier appear on the game detail card or inside the paytable.
Odds and Markets
Asian handicap, over/under, decimal odds and spread are sports-betting terms visible in the sportsbook market list — most commonly when cricket markets for BPL or international fixtures are active. Each term describes how a result is priced and how your stake is calculated against it.
Wallet and Payments
Deposit, withdrawal, e-wallet, Bank Transfer and transaction ID are the words you see in the cashier panel. When you send a Nagad or Upay transfer, the system logs a transaction ID you can use to verify the status in your account history tab without contacting support.
Account and Information
KYC, rollover, turnover requirement, eligible account and terms apply appear in the account verification section and on any active information panel. Reading these correctly tells you exactly what the condition requires before a withdrawal becomes available from that balance.
CORE GAME TERMS
Core Casino Terms — Plain Definitions
These are the six terms you will encounter most often before and during a game session. Each definition is written to reflect how the term actually behaves in the lobby, not a textbook version.
What is RTP?
RTP stands for Return to Player. It is a percentage published by the game provider showing the theoretical long-run return on all wagers placed. We display RTP only where the provider makes this figure available in the game's published paytable or information panel.
What is house edge?
House edge is the mathematical advantage the game holds over the player across all outcomes.
What is volatility?
Volatility describes how a slot pays out — frequently in smaller amounts (low volatility) or rarely in larger amounts (high volatility).
What is a wager or turnover requirement?
A wager or turnover requirement is the total stake amount you must place before a balance from a specific information becomes available for withdrawal. The exact figure and qualifying games are stated in the terms attached to that information in your account area.
What is a jackpot in slot terms?
A jackpot in a slot game is the highest prize-tier outcome defined in the game's paytable. It is triggered by a specific symbol combination or feature round. The value and trigger conditions are set by the game provider and visible inside the game's own information screen.
What is a live dealer?
A live dealer is a real person dealing cards or spinning a wheel in a studio, streamed to your screen in real time.
ODDS PAYMENT ACCOUNT TERMS
Odds, Payment and Account Terms Defined
This set covers the terms that come up once you move beyond the game itself — into the sportsbook, the cashier panel and your account verification steps. Each one has a specific meaning that changes how you act.
What is Asian handicap?
Asian handicap is a sports-betting format that removes the draw outcome by giving one side a fractional or whole-goal head start. It is common in cricket and football markets. The handicap value is set per fixture and shown next to the market name in the sportsbook.
What is over/under betting?
Over/under is a market where you bet on whether a measurable outcome — total runs in cricket, total goals in football — finishes above or below a set figure. The figure is stated on the market line. Your stake settles based on the final count, not the match result.
What is a rollover?
Rollover is another word for a turnover or wagering requirement. It states how many times a specific balance must be staked before it can be withdrawn. Each information panel in the account area shows its own rollover figure and which game categories count toward it.
What is an e-wallet in the payment panel?
An e-wallet is a mobile-linked digital account — such as Nagad or Upay — that you use to send or receive funds without a physical bank card.
What is KYC?
KYC stands for Know Your Customer. It refers to the identity verification steps your account may require before a withdrawal is processed. The specific documents or confirmation steps are shown inside the account verification section. Completing KYC accurately avoids delays on outgoing transfers.
What is decimal odds format?
Decimal odds express the total return per unit staked, including the original stake. A line showing 2.50 means a 100-taka stake returns 250 taka in total if the outcome wins. This format is the standard display in our sportsbook and applies across all listed markets.
TERMS IN REAL LOBBY DECISIONS
Seeing These Terms Together on a Real Screen
Understanding a term in isolation is one thing; seeing how several terms interact in a single decision is more useful.
Volatility on the Game Card
Before starting Crash Win Builder or any slot, the volatility label on the game card tells you whether to expect frequent smaller returns or less frequent larger ones. It shapes session length decisions, not the eventual outcome — the RTP stays fixed regardless of session duration.
Decimal Odds in the Cricket Market
When a BPL or international cricket market is open in the sportsbook, each outcome shows a decimal odds figure.
Turnover Requirement and Your Wallet
If an active information has added a balance to your account, the turnover requirement is shown in the information detail panel.
KYC Step Before First Withdrawal
The account verification section surfaces the KYC step automatically when a first withdrawal is requested. The fields and document types required are listed there. Completing them accurately is a one-time step; once verified, the same account handles all subsequent Upay or Bank Transfer withdrawals.

USING THESE FEATURES YOURSELF
Using the Features These Terms Describe
These questions are about acting on what the terms mean — finding a setting, completing a step or reading a screen correctly inside your account.
Where do I find the RTP figure for a specific slot?
Open the game's information or paytable screen — usually accessed through an info icon on the game tile. RTP is shown there only if the provider has published it. We do not display figures that the provider has not verified and released for that title.
How do I check my turnover progress toward a information condition?
Log in and open the information or bonus section of your account. Active information panels show the current qualifying stake total against the required turnover figure. The count updates as your eligible session stakes are recorded, so check after each session for the latest position.
What does my transaction ID look like and where do I find it?
After a Nagad, Upay or Bank Transfer deposit is submitted, a transaction ID appears on the confirmation screen and in the payment history tab of your account. It is a unique reference string. Keep it accessible if you need to raise a payment query with support.
How do I start the KYC verification step on my account?
Go to the account settings or verification section shown after login. The steps required are listed there with the specific fields and document types needed. Follow each step in the order shown. The section updates automatically once each stage is confirmed by the account system.
Can I switch between decimal and other odds formats in the sportsbook?
Check the sportsbook display settings or your account preferences panel — odds format options are listed there if the feature is available for your account. The setting applies across all open markets including cricket and football lines without needing to reload each market.
Where do I see which game categories count toward a rollover requirement?
Open the information detail from the information panel in your signed-in account. The eligible game categories are listed in the terms attached to that specific information. Different information may list different eligible categories, so always read the terms for each one separately.
