Dude is a game in which you say dude. The word dude appears on each card in one of six different ways, with 12 "dooode" cards, 12 "dewd" cards, 12 "dude." cards, "12 dude?" cards, 12 "tiny dude" cards, and 12 "tie-dyed dude" cards.

The goal is to quickly find matches for as many of your cards as you can. To play, you say the word dude as you think it should be said, based on how it appears on your card. At the same time, listen to how the other players are saying the word dude. Trying to figure out whether you have the same card as another player is the essence of Dude.
