Games are played in four quarters of 10 (FIBA) or 12 minutes (NBA). College men's games use two 20-minute halves, college women's games use 10-minute quarters, and United States high school varsity games use 8 minute quarters.
In NCAA men's basketball, beginning with the seventh foul of the half, one free throw is awarded; if the player makes the free throw, another is given. This is called shooting a one-and-one. Starting with the tenth foul of the half, two free throws are awarded.
