Cricket Formats Explained
Betting markets differ by format. Understanding each format makes it easier to place informed bets.
T20
20 overs per team. Matches typically finish in 3–4 hours. Betting markets: top run-scorer, powerplay score, match winner. BPL and IPL are played in this format.
One-Day International
50 overs per team. Lasts all day. More options in the betting market: innings breakdown, mid-match live odds. The ICC World Cup is played in this format.
Test Cricket
Played over 5 days, with 2 innings per team. Long-form betting markets: series winner, century prediction, draw probability. Bangladesh Tigers regularly play Test cricket.
The Hundred
100 balls per team. A new and exciting format. Betting markets: score per 10 balls, special moment betting. It is gaining popularity in England.
Major Leagues
Familiar Bangladeshi Games
Play the familiar local card games online at okbz.
Teen Patti
Played with three cards, and the best hand wins. Play against a live dealer or with other players.
Tip: Start with small bets and learn the hand rankings well.
Live Dealer & MultiplayerAndar Bahar
One card is revealed and players bet on which side the next card of the same value will appear — "inside" (Andar) or "outside" (Bahar).
Tip: The simple rules make it ideal for new players.
Live DealerCallbreak
Cards are dealt among four players, and each bids how many hands they will win. Spades are the highest trump. Points are earned by meeting your bid.
Tip: Look at your cards and place a realistic bid.
MultiplayerLudo / Rummy
Ludo is a board game where dice are used to move pieces forward. In Rummy, players arrange cards to form sets or sequences.
Tip: Don't be fooled by familiarity — strategic players have the edge.
MultiplayerExciting Crash Games
In crash games like Aviator and JetX, a multiplier keeps rising and can "crash" at any moment. Cash out before the multiplier crashes and the win is yours.
Place your preferred bet amount before the game starts.
The multiplier rises from 1x — 2x, 5x, 10x or even higher.
Cash out before the plane crashes. Wait too long and you lose your entire bet.
Use the auto cash out feature to cash out automatically at a set multiplier.
Important: Set a stop limit before you start playing. Do not trust any predictions or "signal" claims — every round is completely random.
Aviator by Spribe
The world's most popular crash game is now available at okbz. Each round lasts just a few seconds — quick decisions, quick results.
Important Glossary
Plain explanations of essential betting and casino terms for new players.
RTP (Return to Player)
A percentage that shows how much a game returns to players over the long term. The higher the RTP, the more the game theoretically pays back.
House Edge
The mathematical advantage built into every game in favour of the casino. It is the opposite of RTP — a lower house edge is better for the player.
Wager / Wagering Requirement
The number of times you must wager bonus funds before you can withdraw them. Example: 15x means a ৳1,000 bonus requires ৳15,000 in total bets.
Stake
The amount of money you place on a single bet. Always set your stake according to your budget.
Odds
A numerical expression of the probability of an event occurring. Higher odds mean a higher potential win — but also a lower probability.
Parlay / Accumulator
Placing multiple bets together on a single ticket. If all outcomes are correct, the winnings multiply significantly, but one wrong result means the entire bet is lost.
Live Bet
Betting in real time while a match is in progress. Odds change every moment, giving analytical players a chance to spot opportunities.
Cashout
Selling your bet at a set value while it is still running, to secure a profit or reduce a loss. Especially important in crash games and live betting.
Bankroll Management
Managing your total gaming budget wisely. Betting a small portion of your total bankroll on each wager is the key to lasting longer.
Volatility
The variability in how often and how much a game pays out. High volatility means bigger wins but less frequently; low volatility means smaller wins more often.
Free Spin
Complimentary spins awarded as a bonus in slot games. Winnings from free spins usually have a wagering requirement.
Spread Betting
Betting on a specific margin or point difference. In cricket, run spread or wicket spread are popular betting options.
