A game apparatus includes a circular mat providing a smooth, non-friction surface for rollably supporting marbles and a border mat about the edge of the circular mat having cooperative edge regions overlapping each other so that the edge of the circular mat defines a circular marble collection area with a raised barrier carried on the border mat. The circular mat and border are coaxially disposed with respect to each other. Obstacles reside beneath the mats to provide sloping barriers for affecting travel of marbles across the mat surfaces.
