Websites like Duel Board and Rook-Online.com have Adobe Flash Player-based versions of the card game. Rook is licensed by Hasbro, so many of these sites call their version of the game "Raven."
While Rook has a specific deck based on a French tarot deck, Rook can be played with a standard playing card deck by removing the twos, threes and fours. Aces stay in the deck, and one of the joker cards gets added to serve as the Rook Bird card. The scoring gives five points for fives, ten points for tens and twenty points for the joker. Aces are always played as high cards.
