Ludocity is a collection of pervasive games, street games and new sports - social forms of play that take place in public spaces, such as city streets, parks and public buildings.

Some of the games on Ludocity overlap with theatre, painting, dance, and other art forms. Some of them use balloons, lumps of coal, huge sheets of paper, mp3 players, elaborate costumes, and short-range radio broadcasts. All of them have had their rules released under a creative commons licence, giving everyone permission to run that game for free, wherever and whenever they like.
