Martian Chess is a fast and easy to learn Chess-style game with a difference that really makes you think: ownership of pieces is determined not by color, but by location on the gameboard. For this new edition, we have created a new color, Martian Red, and since color has no meaning in this game, all 18 pieces in the set will be of this new color. As a Pyramid Arcade expansion, one set of Martian Chess brings Pyramid Arcade up to eleven color choices. Players: 2 players | Ages: 8+
