How to Play Between Two Castles: Essential Edition

About Between Two Castles: Essential Edition, from BoardGameGeek:

Between Two Castles Essential Edition is a competitive drafting, tile-placement game for 1-8 players designed by Ben Rosset and Matthew O'Malley. It plays in about 45-60 minutes. The Essential Edition combines the original game and the Secrets & Soirees expansion into one box. The king demands a castle! You are a world-renowned master builder who has been asked by the king to help design his castles. Projects of such significance require the expertise of more than one person, so for each assignment you are paired with another master builder to execute your grandiose plans. Will your planning and partnership skills be enough to design the most impressive castles in the world? Between Two Castles is a competitive tile-drafting game in which each tile is a room in a castle. You work together with the player on your left to design one castle, and with the player on your right on another castle. On each turn you select two tiles from your hand, reveal them, then work with your partners to place them. At the end of the game, each castle is scored. Your personal final score is the lower of the scores of the two castles you helped design, and the player with the highest final score wins the game. To win, you have to share your attention between two castles. -description from the publisher Includes the following in the box: Between Two Castles of Mad King Ludwig: Saxophone Room Promo Tile Between Two Castles of Mad King Ludwig: Dice Tower Room Promo Tile Between Two Castles of Mad King Ludwig: Bonus Card Promo Pack #1
