Bit by bit, players reveal sky tiles that show 1-3 stars or 1-3 planets. Players wager on which will predominate. When the 4 planets nearest to a telescope are revealed, wagers are resolved. Though the game steadily progresses, it's not completely static, as face-up tiles can be replaced with facedown tiles drawn from a bag. A light memory game with a nice tactical element. - BoardGameGeek
