UNO

Uno (/ˈuːnoʊ/; from Italian and Spanish for 'one') is an American card game which is played with a specially printed deck (Mau Mau for an almost identical game played with normal playing cards). The game was originally developed in 1971 by Merle Robbins in Reading, Ohio, a suburb of Cincinnati. It has been a Mattel product since 1992. The game's general principles put it into the Crazy Eights family of card games.
