Castlequest is a new kind of card game which uses original picture cards. There are 4 different arena cards and 14 different character cards. Each character card has a rating for each arena. For example, a King card has a higher rating in the Castle arena than it has in the Battleground arena. You play against the computer. The game starts with an arena card being randomly selected and each player (you and the computer) getting 5 cards. You then try to play the highest ranking card that you have for that arena. Each time a hand is played, a new card is drawn from the deck until no more cards exist. If an arena card is drawn, you may change the arena.
