The main formats at a glance
| Format | Length | Overs | Possible results |
|---|---|---|---|
| Test | Up to 5 days | No limit per innings; each side bats up to twice | Win, loss, draw or tie |
| One Day International (ODI) | About 7 to 8 hours | 50 per side | Win, loss, tie or no result |
| Twenty20 (T20) | About 3 hours | 20 per side | Win, loss, tie (often a Super Over) or no result |
Shorter competitions exist too, such as 10-over and 100-ball formats. They follow the same basic idea of a limited-overs chase.
Test cricket
Each team gets two innings, and a team wins by scoring more runs and dismissing the opposition twice. Because time can run out, a draw is a real outcome. That is why Test markets often have three results (team A, team B or draw) rather than two. Pitches wear over five days, so conditions on day one can differ a lot from day five, and weather can affect the outcome.
One Day Internationals
Each side bats once for up to 50 overs. Fielding restrictions apply in set phases, so the first overs usually favour batters and the middle overs are slower. Rain can shorten a match, and organisers usually use the Duckworth-Lewis-Stern method to set a fair revised target.
Twenty20
With only 20 overs, T20 is fast and volatile. A few big overs can change the favourite. The opening six overs (the powerplay) have fielding restrictions, and a toss can matter if dew makes the ball harder to grip later in the evening. Many franchise leagues, including the Indian Premier League, use this format.
Why the format matters before you take part
- Volatility: shorter formats swing faster, so odds can move quickly during a match.
- Draws: only Tests regularly end level on result, so check which outcomes a market covers.
- Weather rules: rain can change targets or cancel a match. Read how your market is settled if a game is shortened or abandoned.
- Conditions: pitch, venue and time of day affect scoring in every format.
No format makes a result predictable. Understanding the game helps you follow it, but it does not guarantee an outcome.
