The game can be played from two players to a number of players limited only by the size of their table. The game takes only a couple of minutes to play, with guaranteed entertainment. Invisible can be played as a party game or can be played as a filler between two serious, strained games. Its box has a two-phase lenticular picture on it that changes depending on the angle you look at it, so the box can show the core of the game, as some things on it turn visible, or invisible.
