It’s a well-worn story by now in the Land of Danger: An army attacking a castle. Somehow, though, the story keeps happening, and another bellicose mob has advanced on the imposing walls of someone else’s keep. The clash to control those walls is at hand. Lead the Blue attackers or the Red defenders, using clever card play and a touch of luck to control more sections of the wall than your opponent
The game consists of 54 cards -- 5 walls, a Red personal deck of 8 cards, a Blue personal deck of 8 cards, and a main deck of 33 cards.
Players take turns playing Archer, Cannon, Attack, Leader and Flag cards from their hands to the different walls. Archers & Cannons each have a strength value, and the player with the most total strength at a wall controls it. Attacks remove the opponent's cards, Leaders each have a unique ability that impacts how strength is calculated at a wall, and Flags lock down the control of a wall and trigger the end game.
The player controlling the most walls at the end of the game is the winner.
