Abstract: A solar system conquest game has a game board including a plurality of movement paths that form a first set of concentric circular orbits and a second set of orbits intersecting the circular orbits at pre-selected locations with these orbits defining movement paths for playing pieces corresponding to each player. The intersections define exchange points where pieces may change orbits. A set of cards determines additional pieces to be entered onto the board by a player, and dice determine the number of movement steps to be traversed by a player during his turn, and a second set of dice controls the outcome of a confrontation between playing pieces. The game board may further be divided into a number of sectors, and a set of instruction cards influence events in a particular sector for all players having pieces located therein.
