1-4 Player Competitive with Ice & Fire - When setting up for a standard, competitive game, DO NOT add these Cooperative Play components to the game, as the Night King cannot be used: Night King components (his mats, figure, and shield), Ice & Fire Action and Round Mats, the Treaty Mat, Blue and Brown Exploration Tokens, Ranger Cards, the 2 North of the Wall Map Mats, and the single castle for Craster’s Keep.
Instead, set up components this way:
1. Use the Action Mat and Round Mat from the base game (instead of Ice & Fire).
2. Shuffle the Ice & Fire Plot Cards into the deck.
3. Shuffle the Night’s Watch and House Targaryen into the house components.
5-Player Competitive - Use the additional Action Die and Coin for a fifth player! Instead of using the base game's Round Mat, flip the Ice & Fire Round Mat to its 5-PLAYER side. Note that there are only 5 rounds and the scoring phases are different.
5-Player Cooperative - Flip the Treaty Mat to its 5-PLAYER side. You now need to control 8 Castles to enter and control King's Landing.
