Parity Games are (possibly) infinite games played on a graph by two players, 0 and 1. In such games, game positions are assigned priorities, i.e. natural numbers.
 
The winner of a finite play of a parity game is the player whose opponent is unable to move. The outcome of an infinite play is determined by the priorities of the occurring positions. Typically, player 0 wins an infinite play if the highest infinitely often occurring priority is even. Player 1 wins otherwise. Whence the name "parity".
 
Parity games lie in the third level of the borel hierarchy and are as such determined^[1]. Games related to parity games were implicitly used in Rabin's proof of decidability of second order theory of n successors, where determinacy of such games was proven^[2]. Knaster-Tarski theorem leads to a relatively simple proof of determinacy of parity games^[3].
 
Moreover, parity games are history-free determined^[3][4], so that if a player has a winning strategy then she has a winning strategy which depends only on the board position, and not on the history of the play.
