Why These Definitions Matter for Your Account

Seeing a term you don't recognise mid-session can cost you a decision. When you know what volatility means before you pick a slot, or what rollover means before you accept a promotion, you're making choices based on facts rather than guesswork. This glossary covers the words that come up most often across our lobby — slots, live tables, sports markets, and the

cashier. We've written each definition the way a cashier desk would explain it: short, direct, and tied to how the feature actually works on ok90. Availability of all features depends on your local law and eligible regions.

Essential Casino Terms Defined

The words every player should know before opening a game or placing a wager.

Return to Player — the percentage of total wagers a game pays back over many rounds. RTP is shown only where the game provider exposes it; check the game's info panel for the figure.

The mathematical advantage the platform holds on each bet. A 2% house edge means, over time, the platform retains roughly 2 units for every 100 wagered across all rounds.

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

The total amount you must bet before a promotional balance can be withdrawn. If a promo carries a 10x turnover, a 500 BDT balance requires 5,000 BDT in qualifying bets first.

A large prize-style feature built into certain slots. Some are fixed amounts; others accumulate across player activity. The game's paytable shows the current cap and trigger conditions.

A real human dealer running the game — dealing cards or spinning a wheel — streamed to your screen in real time. Studios like Evolution power most live tables in our lobby.

Betting, Payment, and Account Language

Terms that come up in sports markets, the cashier, and your account verification flow.

A betting format that removes the draw outcome by giving one side a fractional goal advantage. Common in cricket and football markets, it narrows the bet to two possible results instead of three.

A wager on whether a combined total — runs, goals, points — will be above or below a line set by the market. In cricket, this often applies to total runs in an innings or match.

Another word for turnover requirement. It specifies how many times a bonus amount must be wagered before a withdrawal is processed. Always check the rollover multiplier before activating a promo.

A mobile money account — bKash, Nagad, or Rocket — used to fund your ok90 account. You send from your wallet app to the account number shown in the cashier, then confirm with your PIN.

Know Your Customer — the identity verification step required before withdrawals are processed. You submit a valid ID document; once verified, withdrawal requests are reviewed against that record.

Account-level controls that let you set boundaries on how much you deposit or wager in a given period. You can adjust these in your account settings at any time.

How These Terms Apply on ok90

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

Open the slot and tap the information or paytable icon — usually a small 'i' or menu symbol. RTP is displayed there only when the provider has made it available for that title.

The rollover multiplier is shown on the promo detail page before you activate it. Your qualifying bets are tracked in your account history; the balance unlocks once the total is reached.

KYC is typically required before your first withdrawal. You'll be prompted to upload a valid national ID or passport. Once our team reviews and approves it, withdrawals proceed normally.

Yes — Asian handicap and over/under markets are available on cricket fixtures including BPL matches, where available. Check the sportsbook market list for the specific fixture you want to bet on.

Reputable providers like Pragmatic Play and PG Soft use independently audited random number generators. The provider name is shown on the game tile; you can check the provider's own site for their certification details.

Yes. Log into your account, go to account settings, and update your limits. Some increases may have a short processing period to take effect, depending on the type of limit you're adjusting.
