'The Game You Can't Get Enough Of!' Obsession by Marx Toys is about rolling 2 dice, and moving your rings forward, or your opponent's rings backward, depending on the numbers that are rolled, and the numbers for the rings that are in play. Rings that are in your Safety Zone can't be moved by your opponent. Game ends when one player has 10 rings in the Safety Zone or at the top of his area. - BoardGameGeek
