Cricket Format Guide
Each cricket format has its own characteristics — and different betting markets. Understand it in plain language, like a friend from Dhaka explaining it to you.
T20
20 overs per innings — a total of 40 overs per match. Usually finishes in 3-4 hours. Packed with big hits, fast runs, and eye-catching moments.
Betting markets: match winner, top run scorer, total sixes, runs per over.
One-Day (ODI)
50 overs per innings — a match lasting around 7-8 hours. Requires more strategy and consistency.
Betting markets: half-time score, partnership, powerplay runs, series winner.
Test
Up to 5 days per match — the ultimate test of cricket. Every session and every wicket can bring a dramatic shift.
Betting markets: match draw or win, innings runs, first innings lead, day-session result.
The Hundred
Just 100 balls per innings — a completely new format. Even shorter than T20 and full of action.
Betting markets: wickets, boundaries, special ball moments, and set-based markets.
Major Leagues
Live Betting & Cash Out
Live betting, or in-play betting, means you can place bets even after a match has started — odds change after every ball, every over, and every wicket. That constant movement is what makes live betting different.
For example, in a T20 match between Bangladesh and India — if three wickets fall in the first powerplay, the odds for that team to win drop. Then a big six or a wicket-taking delivery can flip the odds in an instant.
What is Cash Out? During a match, before the final result, you can withdraw the partial or full value of your bet. If your team is performing well but you want to reduce your risk — cashing out can be a smart move.
Stay calm in fast-moving markets — 4 tips
-
Set a budget in advance
Decide how much you will bet for each session before you start — don't let the excitement of live moments push you past your limit.
-
Learn to read the odds
Rapidly falling odds mean that outcome is more likely — understand this signal before placing your bet.
-
Use cash out strategically
When you are in a profitable position, do a partial cash out to secure your winnings.
-
Avoid rushing
Live markets move fast — don't make another mistake trying to recover from the first one.
Crash games — fast-paced thrills
Crash games like Aviator and JetX have brought a completely new kind of excitement to online gaming. A round lasts anywhere from a few seconds to a few minutes — making it ideal to play whenever you have a spare moment.
How a round works: You place your bet before the plane or rocket starts to fly. As it climbs, the multiplier keeps increasing — 1x, 2x, 5x, 10x or more. You must cash out before it crashes. If you don't do it in time, your entire bet is lost.
Auto cash out: Set a multiplier in advance and the game will cash out automatically when that point is reached. This is useful for players who can't keep their eyes on the screen or feel uncomfortable making split-second decisions.
RTP and house edge explained
RTP, or Return to Player, is a percentage that tells you how much money, on average, comes back to players out of every ৳100 wagered over the long term. For example, if a slot has an RTP of 96%, on average ৳96 is returned and the casino keeps ৳4. However, this figure is an average across millions of rounds — it is not a guarantee for any single session.
Typical RTP ranges for different games:
- Slot games: usually 92%–98% — varies from game to game
- Blackjack: up to around 99% with correct strategy
- Roulette: around 94%–97% on European roulette
- Baccarat: 98%+ possible on player / banker bets
What is the house edge? The house edge is the flip side of RTP — the casino's mathematical advantage. If the RTP is 96%, the house edge is 4%. This is not cheating; it is part of the mathematical design of the game.
Understanding RTP and volatility before you play is important. High-volatility games pay out big wins less frequently but in larger amounts — low-volatility games pay out smaller wins more frequently. Choose a game that suits your budget and patience.
