Time's Up! is a party game for teams of two or more players (best with teams of two). The same set of famous names is used for each of three rounds. In each round, one member of a team tries to get his teammates to guess as many names as possible in 30 seconds. In round 1, almost any kind of clue is allowed. In round 2 no more than one word can be used in each clue (but unlimited sounds and gestures are permitted). In round 3, no words are allowed at all.

Time's Up! is based on the public domain game known as Celebrities.
