Three-sided football is a variation of Association football in which three teams played instead of just two teams. Danish artist Asger Jorn invented the sport of three-sided football in the 1960’s, a variation of the sport of soccer, Jorn used the game to explain his notion of triolectics, his refinement on the Marxian concept of dialectics, as well as to just confuse us all with big words and unusual concepts.

This game is played in a hexagonal pitch. Rather than competing, the teams are more like playing with each other, agreeing with themselves on what is allowable or not. This game is played without a referee, meaning, no rules. Unlike normal football, the winner is determined not by the team who scored the most goals, but by the team who concedes the fewest goals.

This games is usually played until everyone decides that the game is over, again, no rules. This is more of a recreational sport rather than competitive.

The first known game was organized by the London Psychogeographical Association at the Glasgow Anarchist Summer School in 1993, and a few other games have been played since.
