There are a number of time restrictions that dictate how long a team or player has to make a particular move.
After a team gains possession of the ball, they have 24 seconds - timed by a "shot clock" - to shoot.
Possession is handed to the other team if they fail to do so.
After the attacking team gains possession of the ball in their own half, they have eight seconds to move the ball into the opposition's half.
Otherwise they lose possession.
Throw-ins from the sidelines or free throws must must be taken within five seconds of the re-start.
A player can only be in the opposition's restricted area - or the "key" - for three seconds.
A violation will be called if the player does not leave in time.
Play can be stopped for coaches to discuss tactics and game plans with their players.
Each team can call two time outs in the first half and a total of three in the second half, each lasting for a maximum of 60 seconds.
Only one per team is available in overtime regardless of its duration.
