An Icehouse game based on Conway's Game of Life. It requires one stash of pyramids per player and one chess-board. Each turn, a player places a small onto an empty space, or grows one of their existing pieces (small to medium, or medium to large). Then dead pieces are removed simultaneously from the entire board. As in Conway's Game of Life, a piece's survival depends on the number of adjacent neighbors: smalls need 1-3 neighbors, mediums need 3-5 neighbors, and larges need 5-7 neighbors to survive. Rules Link
