This nostalgic, addictive game is fairly simple in concept: roll the bearing ball uphill by moving the metal rails back and forth. The player who gets the ball to roll the furthest wins while also exercising hand-eye coordination. All in a day's work—or play as we like to say. Plus, this Marbles-branded (and retro-chic!) take on the classic shoot the moon game features some quality updates such as the fine walnut wood construction and enamel-coated rails (for an even smoother ride).
