Materials

• 8 1/2" x 11" board of triangular pieces
• Many colored markers that fit inside the board's spaces; one color per player
• One piece per player that fits on top of a marker and inside of the board's spaces

Rules

• The goal is to create the largest possible shape with some type of symmetry within 15 rounds
• (e.g., bilateral, rotational) 
• A player can perform only one of the following actions per turn:
• mark one empty space
• remove one marker
• try to control an already controlled space 
• Marking is allowed on any triangle whose vertex touches the one of the player's currently marked spaces
• To take over a controlled space, a player must leave their piece on it for one full turn.
• After 15 turns, the player(s) whose spaces create the largest symmetrical shape win(s).
