Cricket Formats Explained
Understanding the different cricket formats makes betting decisions easier. Here are the key differences.
T20 Cricket
20 overs per side. A match typically finishes within 3 hours. The most popular betting markets include match winner, top batter, highest wicket-taker and first six. The fast pace makes in-play betting especially exciting.
One-Day International
50 overs per side, with a match finishing in roughly 7–8 hours. Gameplay is more tactical compared to T20. Betting markets include powerplay score, partnership runs and half-century markets.
Test Cricket
Matches last up to 5 days, with each side playing two innings. Betting markets include match draw, series winner, first innings lead and century scorer. The preferred format for patient bettors.
The Hundred
England's new format — 100 balls per side. Even faster than T20, finishing in 2–3 hours. Betting markets for runs in the first 10 balls and individual performance are popular.
Popular Cricket Leagues
Local Card Games
Familiar card games from home are now online — play with live dealers and other players together.
Teen Patti
Each player receives 3 cards. The strongest hand wins. Can be played against a live dealer or against other players.
💡 Tip for beginners: start small and memorise hand rankings.
Andar Bahar
A joker card is placed on the table. You bet on which side (Andar or Bahar) a card of the same value will appear. Played with a live dealer.
💡 Tip for beginners: it's a 50-50 chance, so build your bankroll gradually.
Callbreak
A card game for 4 players. Each round you bid how many hands you will win. Spades act as the trump card. Played against other players.
💡 Tip for beginners: count your trump cards before placing your bid.
Ludo / Rummy
In online Ludo, roll the dice and move across the board. In Pool Rummy, match cards to form sets and sequences. Both are played against other players.
