Why These Definitions Matter at the Table

Knowing what a term actually means changes how you play. When you understand house edge, you pick games where the numbers work better for you. When you know what rollover means on a promotion, you can judge whether it's worth taking. At 98db, we put RTP details on screen wherever Pragmatic Play, Evolution, or PG Soft exposes them — so you're reading

real figures, not guesses. Slots, live baccarat, Crash Burst, Dragon Tiger VIP Table — each game type has its own language. This glossary walks you through all of it, from account setup terms like KYC to payment terms like e-wallet and wallet verification via bKash, Nagad, or Rocket.

Core Casino Terms: What They Actually Mean

These are the words you'll see most often in the lobby — on game tiles, in promotion descriptions, and in account settings. Read them once and they'll stick.

RTP is the percentage of total bets a slot or table game returns to players over time. A 96% RTP means the game keeps 4% on average. It is a long-run figure, not a round-by-round promise.

House edge is the casino's mathematical advantage on any given game, expressed as a percentage. Baccarat has a low house edge on the banker bet; some slots run higher. It does not change per session.

Volatility describes how a slot pays out — high volatility means bigger wins that come less often; low volatility means smaller, more frequent payouts. Gates of Olympus runs high volatility; many classic slots run low.

Wager and turnover both refer to the total amount you bet. In promotion terms, a turnover requirement means you must place that total in bets before a bonus converts to withdrawable balance.

A jackpot is the highest prize a slot can pay, triggered by a specific combination or feature round. We show jackpot mechanics on game detail pages where the studio publishes them — we do not invent figures.

A live dealer is a real person dealing cards or spinning a roulette wheel from a studio, streamed to your screen in real time. Evolution and Pragmatic Play run our live dealer tables, including Dragon Tiger VIP Table.

Odds, Payment, and Account Terms Explained

Sports betting markets, wallet flows, and account verification each carry their own vocabulary. These definitions cover what you need before placing a bet or making your first withdrawal.

Asian handicap removes the draw outcome by giving one team a goal advantage or deficit before kick-off. It splits the market into two outcomes instead of three, which changes how odds are calculated on cricket and football.

Over/under is a market where you bet on whether a total — runs scored, goals, points — will be above or below a line the sportsbook sets. Common in cricket matches across IPL and BPL fixtures.

A rollover requirement states how many times you must wager a bonus amount before you can withdraw it. A 10x rollover on a 500 BDT bonus means placing 5,000 BDT in total bets before the funds are released.

An e-wallet is a mobile payment account — like bKash, Nagad, or Rocket — that holds funds you can send or receive without a bank card. Deposits via these wallets typically reflect on your 98db account balance quickly.

KYC is the identity verification step we run on accounts before processing withdrawals. You submit a national ID or similar document through your account settings. It is a standard financial compliance process.

Session and stake limits are controls you can set in your account to cap how much you wager per session or per bet. You find them under account settings — they take effect on your next login.

How These Terms Apply on 98db

Definitions are one thing — knowing how they play out in our lobby is another. These questions cover the practical side: how RTP shows up on game tiles, how wallets connect to your account, and how verification works before your first cashout.

RTP appears on the game detail screen where Pragmatic Play, PG Soft, or Evolution publish it. Not every studio exposes RTP — when they do not, we do not display a figure. Open the game tile and look under info or details.

Open your bKash app, go to send money, enter the account number shown on our deposit page, confirm with your PIN, and copy the transaction ID back into the deposit form. Your balance updates once the transaction clears on our end.

Upload a clear photo of your national ID through the verification section in account settings. Our team reviews it and marks your account verified. Withdrawals to Nagad or Rocket are processed only after verification completes.

When you take a promotion, the required rollover amount shows in your bonus details. Place bets across eligible games — Crash Burst, Blackjack PlayZone, or slots — until the total wagered meets that amount, then the balance is released.

Yes. Go to account settings before your session, set a per-bet or per-session limit, and it applies from your next hand. The limit stays in place until you change it from the same settings screen.

In our sportsbook, over/under lines appear under each match alongside the run total. Select the over or under, enter your stake, and the potential return shows before you confirm. Availability depends on local law and eligible regions.
