The best way to experience the absurd fun of Omniana is to give it a try! Here is a fully playable preview of the game using only a small subset of the cards. This printable version has 63 Characters and 18 Situations, whereas the complete game has 140 Characters and 80 Situations. After printing these out, the only other thing you will need to get a game going is something to represent the 21 Droplet of Blood Tokens--pennies would work great.
