Extinction is a chess-like Icehouse game for two players on an 8x8 grid. Each player has five pieces each of three different sized piece. Each size of piece is a different "specie" and has different properties of movement. The largest pieces, "Queens", move like knights in Chess and may only capture the medium pieces, "Drones". Drones move similarly to Rooks, but with a range of motion limited to 2 squares. Drones may capture only the smallest pieces, "Pawns". Lastly, Pawns move similarly to Bishops in Chess, with a limited range of motion of 2 squares, and they may only capture the largest pieces, Queens. A player wins when they have captured 4 pieces of one species of their opponent's playing pieces.
