Each inning is broken into overs; an over is defined as six consecutive deliveries bowled by the same bowler. A bowler is not permitted to bowl consecutive overs. An innings in one-day cricket is made up of 50 consecutive overs that last 210 minutes (three and a half hours). In Test cricket, the total length of the game is five days, so each innings lasts for about three hours. In limited-overs games there are only two intervals at which rests are allowed: before the end of the first hour and after the end of the fifth hour. In such cases, the number of balls remaining in the 40th over is increased by 20 because more than five hours have passed since the start of the match. For example, if the 40th over was being bowled at the end of the third hour, then it would be the 60th ball of the innings. In any case, once the score reaches 100 runs no further scoring is possible. This means that the player who hits the first century will retire with a good score even if some of their team mates still need to go past this mark. However, if none of them do so within the time limit, the player who hit the century can be dismissed as soon as the umpires call time on the day's play. A single is scored when you reach the home team's stadium under your own steam or in a transport vehicle unassisted by another person.
