From the publisher, Playroom Entertainment:In Space Shuffle, form Solar Systems and collect points in a game that is truly out of this world! As you place the planets in their correct galactic order, you will gain points depending on the planet's color and the other colors within that Solar System. But keep your eye towards the sky, as other players will also score points if they are the Space Commander of that certain color. Be the player that has the most points after 5 Solar Systems have been completed and you will get to take a walk on the moon while your opponents are left star-gazing! - BoardGameGeek
