Two players each have a board with a mirror at one side and two two-sided pieces with a red and yellow pattern on them. Each round, one of the cards is turned face up, showing a pattern that can be made with the two pieces and their image in the mirror. Simultaneously, both players try to create the pattern on the card with their two pieces. The first player who manages this gets the card, which counts as a victory point. When the deck is exhausted, the player with the most cards wins. For solitaire play, the rule book includes extra patterns using all four pieces.
