Uno Card Game (shedding type)

Uno is an American shedding-type card game that is played with a specially printed deck. The game's general principles put it into the Crazy Eights family of card games. The game was originally developed in 1971 by Merle Robbins in Reading, Ohio, a suburb of Cincinnati. It has been a Mattel brand since 1992. When his family and friends began to play more and more, he spent $8,000 to have 5,000 copies of the game made.
