Playing period

A playing period may have a fixed length of game time or be bound by other rules (e.g., three outs in baseball or a sudden-death goal in overtime).

Basketball and gridiron football are among the sports that are divided into two halves, which may be subdivided into two quarters.

In limited overs cricket, each of the innings lasts until either all but one of the players on the batting team are out, or a certain number of legal deliveries have occurred.

Additional short innings, which are also limited in the number of legal deliveries, are played if necessary to break ties.

[3] Curling contests consist of a number of ends, where each player on each team throws all of their stones.
