Every Term You Meet at 90ko, Explained

RTP stands for Return to Player. It is the percentage of all wagered amounts a game is designed to pay back over a very large number of rounds.

House edge is the mathematical advantage the platform holds on each game or market. It is the inverse of RTP on slots and a built-in margin on table games and odds markets.

Volatility describes how a slot distributes its payouts. High volatility titles pay less often but can produce larger individual wins. Low volatility titles pay more frequently at smaller amounts. Joker and JDB titles each carry their own volatility profile, which affects how your balance moves during a session.

A wager is any confirmed bet placed in the lobby. Turnover refers to the total amount wagered across a period or toward a condition. If a gameplay has a turnover requirement, the figure shown is the total you must wager on qualifying games before the gameplay converts to withdrawable balance.

A jackpot is a prize-pool feature built into certain slot titles. It is triggered by in-game mechanics specific to that title rather than by the platform. The size and trigger conditions are set by the game provider; 90ko does not separately guarantee or set jackpot amounts.

Live dealer describes games — baccarat, roulette, blackjack, Dragon Tiger — streamed from a studio with a human dealer running the table in real time. You place bets through your browser; the dealer draws or spins physically. The Dragon Tiger Live Room at 90ko is one example of this format.

Asian handicap is a two-outcome betting format used in football and cricket markets. The handicap removes the draw by giving one side a virtual head start. If your team wins by more than the handicap margin your selection wins; ties on the exact handicap line usually result in the stake being refunded.

Over/under is a market on whether a measurable match figure — total runs, goals or points — will finish above or below a line set by the sportsbook. You choose over or under; the result is settled against the final match statistic regardless of which team wins.

Rollover is the number of times you must wager a specific amount before a gameplay balance becomes eligible for withdrawal. A rollover of 5x on a 200-taka gameplay means you need to place 1,000 taka in qualifying wagers. The gameplay detail page on your account shows which games and markets count.

An e-wallet is a mobile money account used to fund or withdraw from your gaming wallet. At 90ko, bKash and Upay are the e-wallet rails available in the cashier. You send from your bKash or Upay app using the reference shown on the deposit screen, and the funds are credited to your account wallet.

KYC stands for Know Your Customer. It is an identity verification step that confirms you are who you say you are before the platform processes certain withdrawals or account actions.

Responsible-play limits are account-level controls that let you set boundaries on your deposit amounts, session activity or account access. They are found in the account settings area. Setting them is voluntary; once applied they take effect according to the conditions shown on the settings screen.

Open the game detail card from the lobby grid. If the provider has published an RTP figure, it appears on that card. Pragmatic Play and Joker titles display it where available. If the field is absent the provider has not released the number for that title.

Log in and open the gameplay or information section of your account. Any active gameplay with a rollover condition shows your current wagered amount against the required total. Eligible games and markets are listed on the same detail page.

In the cashier, select bKash from the deposit method list. The screen generates a unique transaction reference. Open your bKash app, send the amount to the number shown, and enter that reference exactly. The credit appears in your account wallet once the transfer is confirmed.

KYC steps can be triggered when a withdrawal request reaches a threshold, when your account details are updated, or as part of a routine account review. The account section shows any pending verification step with instructions on what document or confirmation is needed.

Yes. Responsible-play controls are in the account settings area. You can apply limits on deposit amounts or session activity. The settings screen shows the exact conditions and the timeframe each limit covers once you apply it.

Eligible game means the specific titles or market types whose wagers count toward the rollover or turnover condition attached to a gameplay. Wagers on non-eligible games do not count. The gameplay detail page lists which categories or specific titles qualify before you accept.
