Helios: The Game of the Gods

Helios (subtitled "The Game of the Gods") is a chess-like game loosely inspired by classical mythology. The "king" for each side is Helios, the sun god, and nine other pieces on each side represent the planets and the gods they are named after. Three other pieces on each side represent Earth's Moon and its orbital nodes. The pieces are made of a plastic called Tenite (according to the rulebook) and resemble chess pieces topped with the traditional planetary symbols. The pieces have movement powers reminiscent of those of chess pieces, but with some differences: several pieces have more than one way to move, one mode of movement - N squares at a time in any direction, repeated 3 times - is not found in standard chess, and generally speaking pieces are limited to moving a number of spaces equal to their relative position from the Sun plus 1 (e.g., the Earth piece can move 4 squares at a time). The board is a 20x20 grid with a block of 40 unplayable spaces in the center. There are special starred spaces on the board which are used by the pieces with weaker standard movement (Mercury and Helios) to teleport around the board. Pieces are captured by landing on them. The object is to put the opponent's Helios in checkmate (or "total eclipse"). In addition to the rules themselves, the rulebook includes information on the gods and planets represented by the pieces.
