Cricket formats are generally dependent on how many overs are played in the match. Twenty20 cricket, which includes the IPL, the Big Bash (Australia) and the Vitality Blast (UK) is played with each team bowling a maximum of 20 overs each and games usually take around 2-3 hours. One day cricket or ODIs are longer, with each side bowling 50 overs each. Last year’s Cricket World Cup was a tournament played in the ODI format. Finally, there is test cricket. A test match should be completed within 5 days, with each side bowling and batting twice each. County cricket in the UK is played in this format. International test cricket is usually played in a series consisting of multiple test matches. Given the wildly different ways the game can be played, the market variety of cricket is enormous.
