10-15 players, aged 5 and up, an ideal indoor game.

All players but one must join hands in a large circle, and the one player must leave the room for a moment.
With one player leading, the players in the circle must tangle themselves in a confusing know by moving under others arms, in circles, etc.
When the knot looks impossibly mixed up, the lone player may be called back into the room, and he must separate their hands.
Once the knot is united, another person is chosen to leave the room and then former outsider may lead the circle in forming the next knot.
