The game is popular in Germany, Austria and Brazil. A history of the game Crazy Eights is still not known and not recorded.
Crazy Eights, also known as UNO, is a game for 2-5 players. At the start of the game, each player receives seven cards. The aim of the game is to lay all of the cards. The round ends as soon as a player lays his/her last card. The point values of each players’ remaining cards are totalled up to give a ‘negative points’ sum. As soon as a player has exceeded the number of negative points allowed, he/she is knocked out of the game.
