From the inside-box-lid copy:'Each player is the owner of a rocket ship designed to reach the moon. In order to launch the rockets, players must first reach the Rocket Launching Platform. Then each player is given a chance to show how well his rocket is made by trying to fly to the moon.'Each player has a thick wooden disc which represents a rocket ship 'of such modern design that they closely resemble 'flying saucers.'' A cardboard backstop is placed at the corner of the gameboard where the moon is located once a player's rocket ship traverses the path on the gameboard and reaches the Rocket Launching Platform, that player flicks their rocket towards the moon. Points are awarded for how close the rocket gets to landing on the moon (i.e., being completely inside the drawing of the moon, without touching its border), with a bonus for being the first to the launch pad. - BoardGameGeek
