Each player starts with 2 spaceships at the yellow line. Movement is forward or sideways, never backwards, to the next ring (filled or empty). Each constellation has two filled rings. Whenever a player first occupies these two filled rings in a constellation, he gets points awarded. If other players do so at a later time they get no points. The game ends when all players have rounded the game board and are back at the yellow line. The player with the most points wins the game.
