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.
Hockey is also sixty minutes, although it is divided into three twenty minute periods. Soccer is ninety minutes long, divided into two forty five minute halves. Baseball is essentially timeless â no clock is used to determine when the game ends. NBA basketball seems to be an outlier. Basketball is also the only main sport that differs in how long it is between college and professional games. A college basketball game is forty minutes, divided not into quarters but into two twenty minute halves.
