From RTP and volatility on the slots floor to rollover conditions on the account wallet, this glossary explains each term in plain language so you can make sharper choices before you fund or play.
Lobby copy moves fast. A live baccarat table shows a squeeze variant label; a slot card displays a volatility badge; a cricket market lists an Asian handicap line. If those labels are unfamiliar, you are guessing rather than deciding.
Terms cluster around four areas of the platform. Spotting which family a word belongs to tells you immediately where to look for it on screen and why it is relevant to your current action.
RTP, volatility, payline, multiplier and hit frequency appear on slot and crash game cards. Some providers surface the exact RTP inside the game info panel; others do not publish it — we show it only where the provider makes it available, not as an invented figure.
Decimal odds, Asian handicap, over/under and spread appear on the sportsbook side, most visibly on cricket and football markets. These terms describe how a market is priced and what you need to happen for a bet to settle in your favour.
Deposit, withdrawal, e-wallet, KYC and wallet balance are the terms you meet the moment you open the account area. They govern how money moves between your bKash, Nagad or Rocket wallet and your bt188 account balance.
Rollover, turnover requirement, qualifying bet and wagering condition all describe what you must do with account credit before it converts into withdrawable funds. These terms appear in the published conditions attached to any account credit offer.
These six terms appear on game cards, in game info panels and in lobby filters across the slots and live casino sections. Each definition below is written to match how the term is used inside the platform.
RTP stands for Return to Player. It is the percentage of total wagers a slot or game is designed to pay back over a very large number of rounds.
House edge is the mathematical advantage the platform holds on any game over time, expressed as a percentage of each wager. On blackjack it is typically under 1% with correct play; on slots it is the inverse of RTP.
Volatility describes how a slot distributes its payouts. High-volatility games pay out less often but in larger amounts when they do hit. Low-volatility games pay smaller amounts more regularly.
A wager is the amount you stake on a single round or bet. Turnover or wagering requirement is a multiplier applied to account credit that tells you the total volume of bets you must place before those f
In slot context, a jackpot is the highest prize a game can award — either a fixed amount set by the provider or a progressive pool that grows with each bet across all players on that title.
A live dealer game is a table game — baccarat, blackjack, roulette or similar — streamed from a studio with a real croupier running the action.
These six terms come up most often on the sportsbook side, in the account wallet area and during the verification process. They are distinct from the game mechanics terms above and describe a different layer of your experience on the platform.
Asian handicap removes the draw outcome from a football or cricket match by giving one side a fractional goal or run advantage. This leaves only two possible results, which tightens the odds range. Lines such as -0.5, -1 or +1.5 appear next to each team in the sportsbook market list.
Over/under is a market where you bet on whether a combined statistic — total runs in a cricket innings, total goals in a match — will finish above or below a line the sportsbook sets.
Rollover is the number of times you must bet a credited amount before it becomes eligible for withdrawal.
An e-wallet is a mobile-based payment account — bKash, Nagad and Rocket are the e-wallets supported for deposits and withdrawals on this platform.
KYC stands for Know Your Customer. It is an identity verification process where you submit documents confirming your name and account ownership.
Decimal odds show the total return per unit staked, including your original stake. Odds of 2.50 mean a 100-unit bet returns 250 units if it wins — 150 in profit plus your 100 back.
Seeing terms used together makes them easier to apply. Say you are looking at a slot on the games floor — the card shows a high-volatility badge and mentions a multiplier feature. That combination tells you the game pays out infrequently but can land large multiplied amounts when it does trigger.
The volatility badge on a game card in the slots section directly affects how you manage your session. High volatility suits a longer wait for a bigger hit; low volatility suits shorter, steadier rounds. The badge is visible before you open the game.
When a cricket market shows a handicap line, the bet slip updates your potential return automatically as the line changes. Reading the handicap number before you add it to the slip prevents settling surprises after the match ends.
If your account wallet shows a pending credit with a rollover condition, the progress tracker next to it counts your wagers against the required total. You can watch it move in real time as bets settle across slots or live tables.
When you request a withdrawal to Nagad for the first time, the account area may prompt a KYC step. Follow the fields shown — name, wallet number and the document type requested — rather than leaving the form incomplete, which pauses the request.
If a term in the lobby or on a payment screen is unclear after checking this glossary, the support routes below connect you to the platform directly. Use the channel that fits your device and time.
The live chat widget is accessible from the account area on both mobile and desktop. Open it when you are already logged in and have the specific screen or term in front of you — support can view the same account context and respond directly to what you are seeing.
For detailed queries — such as questions about a specific KYC document requirement or a rollover condition attached to an account credit — email support is available through the contact address published in the Help section of the site. Include your account reference for a faster response.
The Help section of the site carries written articles on account verification, wallet setup for bKash and Nagad, and information condition explanations. Browse it before contacting support — many term-level questions are answered there without waiting for a reply.
This section covers practical questions about the platform features that these glossary terms point to — distinct from the definitions themselves.
On the slot game card, look for an info icon or a details panel. If the provider has made the RTP available, it appears there.
After logging in, open the wallet or information section of your account. Any active rollover condition shows a progress bar or a wagered-versus-required total. It updates after each settled bet across qualifying game types. Check the attached terms to confirm which game categories count toward that specific rollover.
The KYC process asks for the documents listed in the account verification screen — the accepted document types are shown there. Your bKash-registered number is used to match your withdrawal destination, but identity verification requires the document types specified in the form. Follow the on-screen instructions exactly.
Match abandonment rules are in the sportsbook terms published in the Help section. Generally, markets that have not reached a stated completion threshold are voided and stakes returned to your account wallet. Check the specific market rules before the match starts for the precise condition that applies.
Multiply your stake by the decimal odds shown. A 200-unit stake on odds of 1.90 returns 380 units total — 180 profit plus your 200 back. The bet slip calculates this automatically before you confirm, so you can see the exact return figure without doing the maths manually.
No. Live baccarat has a defined, published house edge that varies by bet type — banker, player or tie — and it is consistent across rounds because it is based on fixed card probabilities.
