Abstract: A portable game apparatus for playing curb ball or other ball game either indoors or outdoors, having a plurality of steps (1, 2 and 3) with means for supporting the steps in a flight such that the front face and top edge of each step provides a striking surface for a ball thrown at the apparatus. A net (4) is suspended between poles (5a and 5b) attached to the top edge (16) of the top step (3) and is preferably angled forwardly at approximately 45.degree.. The net (4) serves as a back stop to keep the ball (9) from going over the top step (3) and also to ricochet the ball (3) toward the striking surfaces underlying steps. The means for supporting the steps (1, 2 and 3) in a flight is provided by supports (7a and 7b) attached to the first and top steps (3) with dowels (8a and 8b) connected vertically between the supports (7a and 7b).
