From RTP and house edge to Asian handicap and e-wallet rollover, this glossary covers the terminology you encounter across the istanastart lobby — slots, live casino, sportsbook and your account wallet. Each definition is written in plain language so you can make sharper decisions before you place a bet or switch game categories.
If a definition here does not fully answer your question — or if a term appears in the lobby that is not listed — our support team can walk you through it. Reach us through the contact routes below; we keep the same channels open whether your question is about a slot mechanic, a sportsbook line or a wallet step.
The chat window is accessible from your account dashboard after login. Use it for quick definitions, lobby navigation questions or any term you see in a game screen or bet slip that you want explained in plain language.
Send your terminology or account question to our support address shown in the Help section of your account. We respond with a full written answer — useful when you want to save the explanation for reference later.
The Help Centre in your account lists common terms grouped by category: game mechanics, payment steps and bet types. It is the fastest route if you want to check a definition without waiting for a reply.
Terminology is not decoration. When you see a slot labelled high-volatility or a sportsbook line with Asian handicap -0. 5, those words carry real meaning about how often a payout round can arrive and which side the line favours. Misreading a rollover condition on an account gameplay, or confusing gross payout with net payout, changes what you actually receive. This glossary exists so that every label in the istanastart lobby — whether it sits on a game tile, a bet slip, a wallet confirmation or a information condition — reads clearly before you act on it.
The four groups below match the areas of the istanastart lobby where you will actually encounter each term. Use this map to jump straight to the definitions most relevant to what you are doing right now — whether that is choosing a slot, reading a football line, topping up via ShopeePay or checking a gameplay condition in your account.
Terms like RTP, volatility, payline, bonus round and RNG appear on game tiles and inside the information panel each title carries. You find them in the slot lobby and on live dealer table cards — open any title's detail view to see the figures the studio has published.
Asian handicap, over/under, moneyline, spread and accumulators live on the sportsbook page. Football markets — Liga 1 fixtures and European leagues — use these terms on every bet slip. Reading them correctly determines the stake calculation before you confirm.
Deposit, withdrawal, e-wallet, KYC, transaction history and wallet balance are terms in your account dashboard. When you add funds via DANA, OVO or GoPay, the confirmation screen uses these labels to show which step is pending and which is complete.
Rollover, turnover, wagering requirement and eligible game list appear in the terms attached to any active gameplay shown in your account. The current state of any gameplay — including which games count toward turnover — is shown in your account dashboard after login.
The six terms below are the ones you encounter most often across slot and live casino categories. Each definition is kept brief and practical.
RTP stands for Return to Player — the percentage of total wagers a game is designed to return over a very large number of rounds. It is a long-run statistical figure, not a per-session promise. Where a studio publishes it, the figure appears in the game's information panel.
House edge is the mathematical advantage the game holds over you across all bets placed. It is the complement of RTP carries a 4% house edge.
Volatility describes how a slot distributes its payouts. High-volatility slots pay less often but the prize amounts tend to be larger when they land. Low-volatility slots pay more frequently with smaller prize amounts. The label appears on the game tile or inside its detail view.
A wagering or turnover requirement is the total bet amount you must place before a gameplay balance becomes withdrawable. For example, a turnover of 10x on a given amount means that total must be staked across eligible games. The exact multiplier is shown in your account reward detail.
A jackpot is a slot's top prize — the highest payout available from that title, reached through specific symbol combinations or a dedicated feature. It is a game mechanic, not a platform schedule. Whether a title carries a progressive or fixed jackpot is stated in the game's own rules.
A live dealer is a real person dealing cards, spinning a roulette wheel or managing a game table via video stream. You place bets on screen while watching the live action. Live Dragon Tiger Gold is one example of a live dealer format available in the lobby.
These six terms come from the sportsbook, wallet and account areas — distinct from the game mechanics above. Each definition covers what the term means in practice.
Asian handicap is a bet type used widely in football markets. It removes the draw outcome by giving one team a virtual head start. A -0. 5 handicap on a favourite means that team must win outright for the bet to succeed. Liga 1 and European football markets use this format regularly.
Over/under is a bet on whether a combined statistic — most commonly total goals in a football match — will be above or below a line set by the sportsbook. You choose over or under; the final count determines the result. The line is shown on each market in the sportsbook.
Rollover is another word for the total wagering required before a gameplay balance or deposit can be withdrawn. It is expressed as a multiplier of the reward or deposit amount. The rollover figure and progress counter for any active gameplay are visible in your account dashboard after login.
An e-wallet is a digital payment account — such as DANA, OVO or GoPay — that you link to make deposits and withdrawals without using a physical card or direct bank entry. ShopeePay and LinkAja are also supported e-wallet options shown in the deposit section of your account.
KYC stands for Know Your Customer — the identity verification process required before you can withdraw funds. It typically involves submitting identification documents through your account settings. The exact documents and steps required are listed in the verification section of your account dashboard.
An accumulator combines multiple individual selections into one bet. All selections must be correct for the bet to pay out. The potential return grows with each added match because each win multiplies into the next. Accumulator options are available on football and other sports markets in the sportsbook.
Seeing terms in isolation is one thing; recognising them mid-session is another. When you open Aviator Crash Game, the multiplier you see climbing on screen is a live payout coefficient — a crash game mechanic where you cash out before the round ends, and the coefficient at that moment determines your return. That is a specific application of the payout concept, not a standard payline structure.
The climbing multiplier is the payout coefficient for that round. Cashing out early locks in a lower coefficient; waiting longer raises it — and raises the risk the round ends before you act. This is the core crash game mechanic in practice.
Side-bet options on this live dealer table each carry a published house edge in the rules panel. The figure is the studio's own disclosure — check it in the table's information view before placing a side bet alongside the main Dragon or Tiger wager.
On a Liga 1 fixture, the Asian handicap line and over/under total appear on the same market row. Selecting one opens the stake field on the bet slip. The potential return shown is calculated from the displayed odds before you confirm.
After a GoPay deposit, your wallet balance and any active gameplay's rollover counter both update in the account dashboard. The counter shows how much turnover remains before the gameplay balance is withdrawable — no separate screen needed.
These questions go one step further — from what a term means to how you actually use the feature it describes inside the istanastart account.
Open the slot tile and look for the information or rules panel — usually a small icon on the game card or inside the game screen itself. Where the studio has published the RTP, it appears there. Not every title exposes this figure; availability depends on the provider.
Log in and open your account dashboard. The gameplay section shows each active item with a progress bar or counter indicating how much turnover has been completed and how much remains. The eligible game list for that gameplay is listed in its detail view on the same screen.
Until KYC is complete, withdrawal requests may be held for review. Once your identity documents are verified through the account settings page, withdrawal requests proceed to the standard processing flow. The verification section in your account shows which documents are still required.
DANA, ShopeePay and LinkAja are listed in the payment section of your account for both deposit and withdrawal routes, where available. The specific options shown depend on your account region and local law. Check the deposit and withdrawal tabs in your account for the current options.
Your wallet balance is shared across sportsbook, live casino and slot categories. Switching between them does not require a separate transfer. The balance shown in the header of each lobby section reflects the same account total in real time after login.
Find the fixture in the sportsbook and look at the handicap column beside the team names. A negative number next to a team means that side gives a head start; a positive number means that side receives one. Select the outcome, review the calculated return on the bet slip, then confirm.
