A card matching game in which players are guards trying to prevent ninjas from infiltrating the castle. Each turn, players will flip two of the face-down cards in the courtyard grid. If those two cards make a match (or a combo) the player must follow the instructions for that match/combo. Players lose if the ninja pawn makes it all the way to the castle or if they take 4 wounds. Players win if they can capture 4 of the ninja cards. It's a game of simple mechanics but thoughtful strategy for gamers of any level. —description from the designer
