Establish a time limit for the game. Nobody likes to play in a game that lasts forever with neither team moving. There are two primary ways of timing a game start timing from the start or else start timing from when the first person gets out. Remember that long games are not fun for people that get out at right at the start, so keep them short and sweet.
