Each player chooses one of four planets for his base. They get a spaceship and 7 conquest marker. The players take turns spinning the spinner and moving the spaceships accordingly. On unoccupied planets conquest markers are placed. On planets marked with a red number, the players have to draw an action card and follow the instructions printed thereon. If the spinner shows a robot, the player may place a robot on an unconquered planet, which now is reserved for later conquest. If the spinner shows a monster, the player may conquer an already conquered planet for himself. The game ends when all planets are conquered or an agreed on time limit has passed. The players add the numbers on their conquered planets and the player with the highest result wins the game. The game was published in the comic magazines "Zack" Nr. 21 and 22 (1980).
