Playing Regulations. A game of basketball is made up of four quarters, each ten (or in the National Basketball Association 12,) minutes long. At the start of every game the referee throws the basketball up in the air, and one player from each team tries to hit it to their teammates, that is called a jump ball..
an average nba game is about 2 30 hours long there s 4 quarters each quarter is 12 minutes long but then there s the halftime commericials and sometimes it goes into overtime then there s the technical fouls and the fouls and the timeouts so it adds up to about 2 30 hours long so yea the game is over
