Gravitation Game of Skill Rolling Moon - 1959 - Pleasantime Games - New Old Stock
Attached to the board are two long metal rods, slightly above the scoring holes. The rods are placed just slightly narrower than a large steel ball that is placed on the rods at the base of the board.
Players must attempt to slide the rods apart and make the ball roll "uphill" before it drops into a score hole. Making it to a higher scoring hole takes quite a bit of concentration as width of the rods at the highest scoring hole is roughly the diameter of the ball.
The first person to score 5,000 or more points is the winner.
