A simple strategy game using Icehouse pieces. Players add pieces to a 3x3 grid whose boundaries are defined by the pieces played. A player wins if he creates a line of 3 pieces of the same size. Nests of pieces count only as the top piece, Trees count as any piece in the tree.
This appeared in Hypothermia #15, and in the ICE-7 packet of reference cards available free when purchasing Icehouse pieces.
