The rules in 3 steps

  1. 1

    Prepare the modifier piles

    Make three piles by card type: Classic, Golden and Radiant. The recommended order is Classic → Golden → Radiant.

  2. 2

    Play chess and draw on turns 1, 8 and 15

    The game plays like a standard chess match. At the end of turns 1, 8 and 15, each player draws 3 cards, keeps one and puts the other two back at the bottom of the pile. The effect is active immediately and stays active until the end of the game.

  3. 3

    Use your modifiers

    Use their effect to your advantage to surprise your opponent. The game ends by checkmate or draw according to standard chess rules.
