Why These Definitions Actually Matter

Knowing what a term means changes how you play. When you understand house edge, you pick games with better return rates. When you know what rollover means, a promo offer stops being confusing and starts being a real decision. At top20, your account dashboard, game info panels, and cashier all use these terms directly — so reading through this once means fewer

surprises later. Whether you're loading up Aviator on your phone or sitting down at a live baccarat table, the language is the same. Get familiar with it here and the whole lobby makes more sense.

Core Casino Terms Defined

The fundamentals every player should know before spinning or betting.

RTP stands for Return to Player — the percentage of total bets a game pays back over time. A slot with 96% RTP returns roughly 96 taka for every 100 wagered, on average across many rounds.

The house edge is the mathematical advantage the platform holds on any game. A 2% house edge means the platform keeps around 2 taka per 100 wagered over the long run, regardless of short-term results.

Volatility describes how often and how much a slot pays out. High volatility means fewer wins but larger amounts when they hit. Low volatility means smaller, more frequent payouts across your session.

A wager is a single bet placed on any game. Turnover refers to the total amount bet over a period or as a promo condition — for example, wagering a deposit amount a set number of times before withdrawing.

A jackpot is the highest prize available in a slot or prize-feature game. Progressive jackpots grow with each bet placed across all players until one round triggers the full prize pool.

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 both run live dealer tables available at top20.

Odds, Payments, and Account Terms

Betting markets, wallet processes, and account verification — all in plain language.

Asian handicap removes the draw outcome by giving one team a head start in goals or points. It narrows the bet to two outcomes and often produces better odds than a standard three-way match result market.

Over/under is a bet on whether a combined total — goals, runs, points — will be higher or lower than a number set by the platform. In cricket, this often applies to total runs in an innings or match.

Rollover is the number of times you must wager a bonus amount before it can be withdrawn. A 10x rollover on a 500 taka bonus means placing 5,000 taka in total bets before the funds become cashable.

An e-wallet is a mobile money account used to send and receive funds digitally. At top20, bKash, Nagad, and Rocket are the e-wallets supported for deposits and withdrawals in Bangladesh.

KYC stands for Know Your Customer — the identity verification process platforms use to confirm who holds an account. It typically involves submitting a national ID or passport before processing larger withdrawals.

Account play limits are caps you can set on your own deposit or session activity within your account settings. They help you stay in control of how much you spend or how long you play in a given period.

How These Terms Apply at top20

Practical answers about how glossary terms connect to real actions in your account.

RTP is shown inside the game info panel where the provider makes it available. Pragmatic Play and PG Soft titles like Gates of Olympus and Mahjong Ways display RTP in their paytable or info screen before you start.

When you activate a promo, the rollover requirement appears in your account under active bonuses. You can track how much of the required turnover you've completed before the funds unlock for withdrawal.

You'll be asked to upload a valid national ID or passport through your account settings. Once submitted, the verification team reviews it — after approval, withdrawal requests above the standard threshold process normally.

Open your bKash or Nagad app, send to the account number shown in the top20 cashier, then confirm with your PIN. The deposit reflects in your account balance once the transfer is confirmed on the wallet side.

Yes. Live baccarat and blackjack typically carry a lower house edge than most slots. Dragon Tiger runs a higher edge on side bets. Game info panels show the edge or RTP where the provider publishes it.

Yes — account play limits are managed directly in your account settings. You can adjust them yourself at any time. Changes that reduce a limit apply immediately; increases may have a short review period.
