Uno
UNO is a proprietary American shedding-type card game originally developed in 1971 by Merle Robbins in Reading, Ohio, a suburb of Cincinnati, that housed International Games Inc., a gaming company acquired by Mattel on January 23, 1992. Played with a specially printed deck, the game is derived from the crazy eights family of card games which, in turn, is based on the traditional German game of mau-mau. Now, you can play this game online against CPUs.
