Why Knowing the Terms Matters

Seeing a term you don't recognise mid-session slows you down. It can mean the difference between choosing a high-volatility slot on purpose and stumbling into one by accident. Understanding rollover conditions before you accept a promotion saves you from confusion later. The same goes for payment terms — knowing what a withdrawal verification step involves means your Nagad or bKash cashout moves

without a hitch. This glossary is here so you spend less time second-guessing and more time making informed decisions about the games and markets you actually want.

Core Game Terms Defined

The words you'll encounter most often in slots, table games and live casino — each one explained in a single clear sentence.

RTP (Return to Player) is the percentage of total wagers a game is designed to pay back over time. It is a theoretical figure shown only where the game provider publishes it.

House edge is the mathematical advantage the platform holds on any game. A 2% house edge means, over many rounds, the platform retains roughly two units for every hundred wagered.

Volatility describes how often and how large a slot pays out. High volatility means fewer wins but larger amounts; low volatility means smaller, more frequent payouts across your session.

Wager and turnover both refer to the total amount staked. In promotion terms, a turnover requirement means you must bet a set multiple of a bonus amount before withdrawing related funds.

A jackpot is the highest prize a slot can award, either fixed at a set amount or progressive, growing with each bet placed across all players until one round triggers it.

A live dealer is a real person dealing cards or spinning a wheel in a studio, streamed to your screen in real time. Evolution and Pragmatic Play both supply live dealer tables on 18coi.

Odds, Payments and Account Vocabulary

These terms come up most often in sports betting, wallet transactions and account verification — worth knowing before you place a bet or request a cashout.

Asian handicap is a betting format that removes the draw outcome by giving one team a fractional goal advantage or deficit. It is common in cricket and football markets and narrows the bet to two outcomes.

Over/under is a bet on whether a combined total — runs in cricket, goals in football — will be higher or lower than a line the platform sets. You pick a side; the final count decides the result.

A rollover requirement states how many times a bonus amount must be wagered before it converts to withdrawable funds. Always check this figure in the promotion details before accepting any offer.

An e-wallet is a mobile-based payment account. On 18coi, bKash, Nagad and Rocket are the local e-wallets used for deposits and withdrawals, with transactions confirmed through your wallet PIN.

KYC (Know Your Customer) is the identity verification process. You submit documents to confirm your name and account ownership. Completing KYC is required before your first withdrawal is processed.

In a crash game like Aviator, a multiplier rises from 1x after each round starts. You cash out before it stops; if you wait too long and it crashes first, the round is lost. Timing is the entire mechanic.

How These Terms Apply on 18coi

Knowing a definition is one thing — seeing how it works in practice on your account is another. These questions cover the most common points where terminology meets real account decisions.

RTP is displayed inside the game information panel where the provider makes it available. Pragmatic Play and PG Soft titles typically show this figure; not every provider publishes it for every title.

Your first withdrawal triggers a KYC check. Submit your identification documents through the account verification section. Once approved, your bKash withdrawal proceeds to the number registered on your account.

Check the game detail panel before launching. Many Pragmatic Play slots, including Gates of Olympus, label volatility directly. If it is not shown, the paytable spread gives a strong indication of the range.

Cricket betting markets, including BPL fixtures, are available in the sportsbook. Handicap formats vary by match and market; check the available lines for each fixture before placing your bet.

If the rollover condition on an active promotion is not met, the bonus portion of your balance remains locked. Your deposited funds are separate and can be withdrawn independently, subject to KYC clearance.

Yes. Rocket works for both directions. Open the cashier, select Rocket, enter the amount, and complete the transfer from your Rocket app using the account number shown. Withdrawals follow the same wallet verification path.
