Castellan Red and Blue
In Castellan; two players work together to build a castle. Finely-detailed wall and tower pieces link together to form courtyards; and the player who finishes a courtyard claims it with a Keep; scoring points for that courtyard equal to the number of tower pieces surrounding it.
In more detail; each player starts the game with two decks of cards: a wall deck and a tower deck. Each card allows a player to play the components shown on it; with the wall deck cards always depicting at least one wall (and some combination of walls/towers) and the tower deck cards always depicting at least one tower (and again some combination of walls/towers). On a turn; a player can play as many cards as she wants; but she draws only one card at the end of her turn. The goal is to create courtyards – and subdivide existing courtyards – while keeping your opponent from doing the same. Players have the same cards in their decks; so the challenge is all about what to use when. The game ends when all the castle pieces are used up; and the player with the most points wins.
Two different pairs of Keep colors are available in the two versions of Castellan; so with two copies of the game – and the right combination of bits – up to four players can play.
