It's a grand old game, and you can't beat a summer's afternoon in the sun with a cold beer or five, very relaxing
Currently, there's 4 forms of the game played..........
20/20 ~ The latest incarnation, both sides face a maximum of 20 overs (120 balls), played with coloured kits, rock music and sometimes under floodlights. Games last around 3 hours.
Limited Overs ~ Can be 45/50/60 overs, lasting anything upto 8 hours. Not as much razzamatazz as the 20/20
4 day ~ Unlimited overs, two innings of 10 wickets a piece, played at a domestic level, the bread & butter of the game
Test Cricket ~ The DADDY!!!!! Played at international level, similar rules to the 4 day game, but with an extra day's play. Regs call for 90 overs to be bowled a day.
Hope that helps
