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..
12 minutes being the standard NBA quarter length. We know that a quarter is 1/4 of a whole. So a whole game is 12 minutes * 4 = 48 minutes in a single game. If the game ends after 48 minutes and the recorded score is tied, an additional 5 minutes is given which is called OT (overtime), not 12 minutes.
