King Louis the Mad Between Two Castles is a tile-selecting game in which each tile is a room in a castle. You work in cooperation with the player on the left to build a castle, and with the player on the right to build another castle. In each round, you choose two tiles from your hand, reveal them, and then, in consultation with your partners, place one selected tile in your two castles.
At the end of the game, each castle receives points. Your own final score will be the lower of your two castles, and the player with the highest score wins the game. To achieve victory, you must divide your attention as well as your devotion between the two castles.
