Castle Panic is a cooperative, light strategy game for 1 to 6 players ages 10 and up. Players must work together to defend their castle, in the center of the board, from monsters that attack out of the forest, at the edges of the board. Players trade cards, hit and slay monsters, and plan strategies together to keep their castle towers intact. The players either win or lose together, but only the player with the most victory points is declared the Master Slayer. Players must balance the survival of the group with their own desire to win.
