Rules

(2-7 players) – This game has especially been popular in college and university crowds since the 1960s, and the aim is not just to win but to have fun. Essentially it is a Crazy Eights variant with special additions, but the rules may not be discussed; new players are expected to try to figure out the rules by observing a game and by trial and error. Theoretically, there are overtones of Mornington Crescent, Fizzbin, and Calvinball, but Mao is a playable game.
