An "over" is a term used in the sport of cricket to describe a set of six legal deliveries bowled by a bowler to a batsman. Each over begins when the bowler delivers the first ball and ends after the sixth delivery. The bowler aims to dismiss the batsman or limit the runs scored during these deliveries. Overs are crucial in determining the pace and strategy of a cricket match. The number of overs in a game can vary, with formats like Test cricket allowing unlimited overs, while One Day Internationals and Twenty20 matches have a fixed number, typically 50 and 20 overs, respectively.
