Crazy Eights (6 letters) and OTTO (4 letters) are two popular card games. Crazy Eights is a shedding-type card game for two to four players, in which the object is to be the first to get rid of all the cards in your hand. The game is similar to Uno, in that each player must match the card previously played by either the number, suit, or rank. OTTO is a trick-taking card game for two to four players, in which the goal is to be the first to reach a certain number of points. Players take turns playing cards from their hands, and the player with the highest card of the same suit as the lead card wins the trick.
