From RTP and house edge to KYC and e-wallet rollover, this glossary covers the terms you will actually see in the batma138 lobby — on game screens, in your account dashboard, and across the deposit flow with DANA, GoPay, and ShopeePay. Each definition is written plainly so you can make informed choices about which game type fits your session and how your account wallet works.
If a term in the lobby or your account dashboard is not covered here, our support team can walk you through it directly. Reach out through any of the channels below — available to players in supported Indonesia regions where local law permits.
Open the chat icon from any page in the lobby. Our team responds in the chat window and can clarify game mechanics, wallet terms, or account steps in real time.
Send your question to our support address found in the Contact section of your account. We reply with a written explanation you can save for reference.
Log in and navigate to the Help section inside your dashboard. It lists definitions for common account, wallet, and transaction terms specific to your region.
Understanding glossary terms becomes practical the moment you open a game or initiate a deposit. When you load Crash Fast Lift, the multiplier displayed on screen is the live odds expression — it rises until the round ends, and your return is calculated from the point you locked in. That is a direct application of the odds concept in a non-sports context. In Live Sic Bo Diamond, the payout ratio shown on each bet zone is the house-edge mechanism made visible: the ratio reflects what the operator retains over many rounds, not a promise on any single roll. When you deposit via DANA, the transaction confirmation in your account wallet is the settlement record — matching the transfer term you will see in your account history tab. KYC appears the first time you attempt a withdrawal; the account screen will prompt you to complete identity verification before the funds move. Recognising each term on the actual screen saves time and removes uncertainty from your session.
The rising multiplier in Crash Fast Lift is a real-time odds display. Lock in before the crash and your return reflects that multiplier. This is the clearest live example of dynamic odds in the lobby.
Each bet zone in Live Sic Bo Diamond carries a printed payout ratio. That ratio is where house edge is encoded — the difference between true probability and what the table pays. Check the ratio before placing.
After a DANA transfer, your account wallet updates with a transaction entry. That entry is your settlement record. It shows the credited amount and timestamp — the same data referenced if you contact support.
The first withdrawal attempt triggers the KYC prompt in your account dashboard. Complete the identity fields shown there before the request is processed. The screen lists exactly which documents are required.
These terms appear in sports markets, payment flows, and account management — distinct from the core game-mechanic vocabulary in the basics section below.
Asian Handicap removes the draw outcome from a football match by giving one side a goal advantage or deficit. You bet on adjusted outcomes, which narrows the market to two results instead of three.
Over/Under, also called totals, is a market where you predict whether a match statistic — usually total goals — will be above or below a number the operator sets for that fixture.
Rollover is the total wagering amount you must reach before a credited gameplay becomes withdrawable. It is calculated as the gameplay amount multiplied by a stated factor, shown in your account dashboard after login.
An e-wallet is a digital payment account — DANA, GoPay, or ShopeePay in our configured routes — that holds a balance you transfer directly to your batma138 account without entering a bank card number.
KYC stands for Know Your Customer. It is an identity verification process required before your first withdrawal. Your account screen will display exactly which documents to submit when the step is triggered.
Play limits are the minimum and maximum amounts configured for deposits, bets, or sessions on a given game or market. The specific figures for each game or wallet method are displayed on the relevant screen in your account.
These are the foundational terms you will encounter across slots, live tables, and crash games in the lobby. Each definition describes the mechanic as it actually works — no assumptions about specific outcomes.
RTP stands for Return to Player. It is the theoretical percentage of total wagers a game returns over a very large number of rounds. A provider displays this figure only where the game or studio exposes it in the lobby.
House edge is the mathematical advantage the operator holds on any given game or market.
Volatility describes how a slot distributes its returns. High volatility means larger prize amounts hit less frequently. Low volatility means smaller amounts land more often. Neither guarantees a specific session result.
A wager, also called turnover, is the amount staked on a single bet or spin. It is distinct from your balance: staking 50,000 from a 200,000 balance counts as a 50,000 wager for that round.
Jackpot is a game's top prize tier, reached through rare symbol combinations or a dedicated feature round. The prize pool and trigger conditions vary by game and are displayed within that game's paytable.
A live dealer is a human dealer streaming from a studio to your screen in real time. In Live Sic Bo Diamond and similar titles, a physical table is operated on camera, and you interact with the game through an on-screen interface.
Different term groups surface in different parts of the batma138 platform. Knowing which screen each family belongs to helps you find the right definition when you need it.
RTP, volatility, bonus round, multiplier, and paytable — these appear on the game's information screen or within the game interface itself. In Crash Fast Lift, the multiplier is the central mechanic displayed live on screen.
Asian Handicap, Over/Under, payout ratio, and spread — these are shown on the bet slip and market listing. In Badminton Uber Cup Bet and football markets, each selection displays its current odds before you confirm.
Balance, deposit, withdrawal, transaction record, and settlement — these are found in your account dashboard after login. DANA, GoPay, and ShopeePay transfers each generate a line entry there with amount and timestamp.
Rollover, turnover requirement, validity period, and minimum odds — these conditions are attached to any active gameplay and are visible in your account dashboard after login, not on a general promotional board.
When you understand what RTP actually measures, you stop treating it as a guarantee and start using it as a comparison point between two slots. When you know how rollover is calculated, you can decide whether a credited gameplay is worth the required turnover before committing your balance. The same logic applies to odds formats: once you understand Asian Handicap, the market listing for a Liga 1 fixture or a European match becomes a clear decision rather than guesswork. Across every game category in the batma138 lobby — slots from Pragmatic Play and CQ9, live tables, and crash games — these terms appear consistently. Getting familiar with them once means every session after that starts from a more informed position. Your account dashboard displays the relevant figures for your active session; this glossary gives you the language to read those figures accurately.
These questions are about how specific platform mechanics work in practice — distinct from the definitions above.
Open the game and look for the information or paytable icon within the game interface. RTP is displayed there only if the studio or provider has made it available. Not every title shows this figure by default.
Log in and go to your account dashboard. The current state of any active gameplay condition, including rollover progress, is shown there. It updates after each qualifying wager is settled.
After completing a DANA transfer, your account wallet reflects the credited amount within the session. A transaction entry in your account history shows the amount, payment method, and timestamp for your records.
If you do not lock in a multiplier before the round ends, your stake for that round is not returned. The game's interface shows the lock-in button clearly during the active round — use it before the round concludes.
KYC verification is triggered when you submit your first withdrawal request. Your account screen will display the required steps and document fields at that point. Complete them as shown to proceed with the transaction.
Yes — sports markets including Over/Under for football fixtures are accessible from the mobile version of the lobby. Navigate to the sportsbook section, select the match, and the available markets display on screen where local law permits.
