Gameplay in Brief:
Players try to be the first to get rid of all their cards by playing one that matches the color, number, or word showing on the topmost card on the discard pile. Players must say "Uno!" when they're down to one card remaining, or else suffer a penalty. Special cards and wild cards add some unpredictability to the game.
Uno is based on the public domain card game Crazy Eights.
For 2 to 10 players, ages 6 and up. About 30 minutes per game.
Uno was designed by Merle Robbins.
Uno was originally published in 1971 by International Games. Today, Uno is published by Mattel. It is believed that more than 150 million copies of the game have been sold.
Numerous special editions, including Spider-Man Uno, Hello Kitty Uno, Harry Potter Uno, Simpsons Uno and Uno Attack have been published. Many of the special editions include at least one card with unique rules.

Uno was the only published game designed by Robbins, a barber originally from Hungary who moved to the United States. He passed away in 1984.
