Game mechanics and payout definitions

These are the terms you see on every slot card, live-table info panel and crash-game screen. Each one describes how the game pays, how often it hits, or how the round plays out.

Return to Player: the percentage a game is designed to pay back over millions of spins. A slot with ninety-six percent RTP keeps four percent as house edge. Higher RTP means the game returns more over time, though any single session can land anywhere.

How often a slot pays and how big those wins are. Low volatility means frequent small wins; high volatility means longer dry runs but bigger payouts when you hit. Medium volatility sits in between. Your bankroll and patience decide which suits you.

The percentage the platform keeps on average across all rounds of a game. If house edge is two percent, you can expect to get back ninety-eight percent over a long series of bets. Every casino game has one; lower is better for you.

The total amount you bet across rounds. Rollover requirements often ask you to wager a bonus amount several times before you can withdraw. If you claim a thousand-taka bonus with five-times rollover, you wager five thousand before cashing out.

A large fixed or progressive prize pool inside certain slots. Fixed jackpots stay the same; progressive jackpots grow with every bet across the network until someone wins. Not every slot has one, and odds of hitting a jackpot are usually very low.

A real person dealing cards or spinning the roulette wheel in a studio, streamed to your screen in real time. You place bets through the interface; the dealer runs the game. Live dealer tables include blackjack, baccarat, roulette and game-show formats.

Sportsbook, payment and verification terms

These definitions cover the terms you see when you open a cricket or football fixture, top up your wallet with bKash or Nagad, or verify your account before a Rocket withdrawal.

A bet type that gives one team a virtual head start to level the match. If Team A gets minus one goal, they must win by two for your bet to pay. If they win by one, it's a push and you get your stake back. Popular in football and cricket markets.

A market where you bet whether the total runs, goals or points will be above or below a set line. If the line is one hundred fifty runs and you pick over, the match must finish above that for you to win. Also called totals.

The number of times you must bet through a bonus or deposit before you can withdraw. Three-times rollover on a five hundred taka bonus means you wager fifteen hundred total. Only eligible bets count; check the terms for excluded games and minimum odds.

A mobile payment app like bKash, Nagad or Rocket that holds your balance and sends money with a PIN. You top up your oklav account by transferring from your e-wallet; withdrawals land back in the same wallet after verification clears.

Know Your Customer: the process where you upload your national ID or passport and a recent utility bill so we can verify your identity. Required before your first withdrawal to Nagad, Rocket or bank transfer. Usually clears within one business day if documents are clear.

An account control that pauses your access for a set period — one day, one week, or longer — so you can take a break. You set it in account settings; once active, you cannot log in or wager until the timer expires. Part of account safety tools.

Common questions about terms and features

These answers explain how the terms in this glossary apply when you are choosing a game, reading the sportsbook grid, or moving money through your wallet.

Tap the info icon on the game card before you open it. If the studio publishes RTP, it appears in the rules panel. Not every provider shares the figure; when it is missing, the game still runs on certified random logic but the percentage is not disclosed.

Check the info panel for a volatility rating — low, medium or high. Some studios label it variance instead. If the game does not state it, look at the paytable: many small wins suggests low volatility; fewer big-multiplier symbols suggests high.

It is the total amount you must wager before the bonus converts to real balance you can withdraw. If you claim two thousand taka with four-times rollover, you bet eight thousand across eligible games. The promo page lists which games count and at what weight.

bKash, Nagad and Rocket deposits usually land in your wallet within one minute. Open your mobile wallet app, send to the account number we show, confirm with your PIN, then return to oklav and the balance updates automatically once the network confirms the transfer.

We verify your identity to meet financial regulations and protect your account from unauthorised access. Upload your national ID and a recent utility bill in account settings; our team reviews it within one business day and unlocks withdrawals to Nagad, Rocket or bank transfer.

Yes. Go to account settings and choose daily, weekly or monthly deposit caps, or set a session timer that logs you out after a fixed period. Once saved, the system enforces the limit until you request a change, which takes twenty-four hours to process.
