Uno (card game)

Uno (pronounced /ˈuːno/) (Italian and Spanish for 'one') is a card game played with a specially printed deck (see Mau Mau for an almost identical game played with normal playing cards). The game was originally developed in 1971 by Merle Robbins. It is now a Mattel product. The game's general principles put it into the Crazy Eights family of card games.
Previously, their slogan was The Colored Card Game. Presently, they are using You know. Their motto is You get one, you get Uno.'
