From RTP and house edge to DuitNow top-ups and KYC checks — this glossary covers the terms that show up across ko88's slots, live casino tables, sportsbook and account pages. Whether you're reading a game paytable, checking your wallet balance or reviewing a bet slip, knowing these definitions helps you make faster, clearer decisions without guessing.
If a term on a game screen, bet slip or account page doesn't match what you read here, reach out directly. Our support team covers account questions, payment routes and lobby navigation — including anything related to DuitNow transfers, Bank Transfer steps or wallet verification. Check your account dashboard for the current contact routes available to you.
Open the chat widget from any page inside your account. Available for quick questions about game terms, wallet status and account steps — the fastest route when you need a definition confirmed in context.
Send a detailed question to the support address shown after login. Useful when you need a written explanation of a term, a transaction query or a step-by-step walkthrough of a payment route like Bank Transfer.
Your account page shows active payment routes, wallet balance and transaction history in one place. Check there first when a deposit or withdrawal term appears on screen — the current state is shown after login without needing to contact support.
Seeing a term in isolation is one thing — understanding where it shows up during a real session is more useful. When you open Palm Valley Megaways, the paytable shows RTP as a percentage and lists the volatility band so you know whether payouts tend to cluster or spread across a long session. On the sportsbook, an Asian handicap appears on the bet slip next to the odds format (decimal or fractional), and the potential return is calculated before you confirm. At the cashier screen, your DuitNow top-up shows a transaction reference alongside the wallet credit status — that reference number is what support needs if you raise a query. The wager or turnover requirement attached to any account credit appears under your wallet summary after login, not on the lobby front page. Knowing where each term lives on screen means you spend less time searching and more time on the game or match you came for.
Open Palm Valley Megaways and tap the paytable icon. RTP is listed there as a fixed percentage — it represents the theoretical return across a very large number of spins, not a session promise.
Select a Liga Super or English Premier League match on the sportsbook. The Asian handicap line sits beside the decimal odds on your bet slip and adjusts the effective scoreline to level the match for betting purposes.
After a DuitNow top-up, your wallet history shows a transaction reference number and a credited status. Quote that reference if you contact support about a pending deposit.
Any account credit with a wager condition shows its remaining turnover requirement inside your wallet summary page — visible only after you log in, not on the public lobby.
These terms cover the mechanics behind bet types, payment flows and account processes that come up once you move beyond basic gameplay.
A bet type that removes the draw outcome by giving one team a virtual head-start in goals. Common on football markets like Liga Super and the English Premier League. Your stake is returned if the adjusted score lands exactly on the line.
A market where you predict whether a match statistic — typically total goals — finishes above or below a set number. The line is shown on the bet slip alongside the odds for each side before you confirm.
The total amount you need to wager before an account credit becomes withdrawable. Your remaining rollover balance is shown inside your wallet summary after login — it updates each time a qualifying bet settles.
DuitNow routes funds directly from your Malaysian bank account to your ko88 wallet using your registered account details. The transaction reference appears in your wallet history once the transfer is received and credited.
Know Your Customer — the identity verification step that confirms your account details match your submitted documents. KYC is required before withdrawals are processed. Follow the verification steps shown in your account settings page.
Your ko88 wallet is the internal balance that holds deposited funds before you place bets or request a withdrawal. It is separate from your Touch 'n Go eWallet or bank account — topping up moves funds from your payment method into this wallet.
Start here if you're new to the lobby. These are the terms that appear most often across slot paytables, live dealer tables and general game screens.
Return to Player — expressed as a percentage, it represents the theoretical amount a game pays back over a very large number of rounds. RTP is shown in the paytable where the game or provider chooses to display it; it is not a session guarantee.
The mathematical advantage the game holds over time, expressed as a percentage of each wager. A game with 97% RTP has a 3% house edge. It applies across all rounds in aggregate, not to any single bet you place.
Volatility describes how a slot distributes its payouts. High volatility means larger prizes appear less often; low volatility means smaller amounts come up more frequently. Volatility is usually shown in the paytable alongside RTP where available.
The total amount staked across bets or spins. In account terms, a turnover requirement is a specified wager amount you need to reach before an account credit qualifies for withdrawal. Your running total is shown in the wallet summary.
Jackpot is a game's top prize — the highest payout available in that title, reached through a specific rare combination or bonus round trigger. Some slots carry a fixed jackpot; others link to a progressive pool shown on screen.
A real person dealing cards or spinning a roulette wheel in a studio, streamed in real time to your screen. Live Penang Table is one example in the ko88 lobby — you place bets through the on-screen interface the same way you would at a table game.
Different parts of the ko88 lobby use different vocabulary. This map shows which term family belongs to which screen so you know where to look.
RTP, volatility, bonus round, scatter, wild and multiplier all live inside the paytable of each slot or table game. Open the info panel on any title — Palm Valley Megaways or Rapid Climb Arena, for example — and these terms are defined there in the context of that specific game.
Asian handicap, over/under, decimal odds, fractional odds and cash out all appear on the sportsbook bet slip. You see them when you select a match — Liga Super or English Premier League markets display odds format and handicap line before you add the selection to your slip.
Deposit, withdrawal, transaction reference, wallet credit and payment route appear across the cashier screen and wallet history page. DuitNow and Bank Transfer are the verified deposit routes — each completed transfer logs a reference number in your wallet history.
Rollover, turnover requirement, KYC status and verification appear inside your account settings and wallet summary pages after login. These terms govern when a credit becomes withdrawable and what documents are needed to unlock full account functionality.
Knowing what a term means changes how you approach a session. Checking the volatility on a slot like Fishing Golden Catch before you start tells you whether to expect frequent small returns or a longer stretch between bigger prize rounds. On the sportsbook, understanding Asian handicap lets you read a Liga Super bet slip accurately instead of confusing the adjusted line with the actual scoreline. At the cashier, knowing the difference between your ko88 wallet balance and your DuitNow account means you can trace a deposit quickly if the credit takes longer than expected. Account terms like KYC and rollover are the ones most players look up only when they hit a withdrawal step — reading them here first means no surprises when that moment arrives.
These questions cover how the lobby, payment screens and account tools actually work — building on the definitions above.
Log in and open the wallet section from your account menu. Your current balance, recent deposits and pending withdrawals are all listed there. Each DuitNow or Bank Transfer entry shows a transaction reference and credited status so you can track every top-up.
Open the slot and tap the information or paytable icon — usually a question mark or menu icon on the game screen. RTP is shown there when the game provider has chosen to publish it. Not every title displays this figure, so check the paytable directly rather than relying on lobby thumbnails.
Check your wallet history for the transaction reference first. If no entry appears after a reasonable wait, contact support via live chat and quote the reference number from your banking app. The support team can match it to the incoming transfer on their end.
Select a match — Liga Super or an English Premier League game — and look at the handicap column. The virtual goal advantage is applied to the final score before the bet settles. If the adjusted margin lands exactly on the line, your stake is returned in full.
KYC is required before your first withdrawal is processed. Your account settings page shows the current verification status and lists the documents needed. Complete the steps shown there — the process is handled entirely within your account without needing to contact support unless a document is flagged.
Any credited amount with a wager condition displays its rollover progress inside your wallet summary — visible only after you log in. The figure updates each time a qualifying bet or spin settles, so you can see exactly how much turnover remains before the credit unlocks for withdrawal.
