Running out the clock
In American football, each quarter of a game is measured with a 15-minute game clock, or 12-minute clock in many high school football codes and the German Football League. A team in possession of the lead and the ball will attempt to use up as much of the game clock as possible in order to bring the game to an end more quickly, thus denying the opposition another chance on offense.

Time limit:
The Game lasts until time runs out or until all questions prepared for the game have been read- whichever comes first. For double or single elimination games, this is 20 questions and two halves of 10 minutes each. For round robin games, this is 15 questions and 14 minutes. There is no half-time in round robin play. There is a timekeeper for each game to make sure the game does not go over the time limit.
