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..
Best Answer: There are 4 quarters to a game, each quarter is 15 minutes of actual playing time. Therefore there will be 60 minutes of actual playing time, but due to commercials, timeouts, instant replay halftime, the games usually last 3 - 4 hours.0 minutes 4 quarters per game * 15 minutes per quarter = 60 minutes per game. That is how long the GAME is. If you want to know how long it takes the game to be played from opening kickoff till the last play is completed, that is a different question with a lot of different answers, because every NFL game is different.
