Abstract: A platform for a ball game having a generally circular platform frame made from a plurality of arc segments joined by a plurality of arc connectors, wherein two of the arc connectors are hinged arc connectors. The two hinged arc connectors are oppositely disposed on the platform frame so that the frame is movable between a flat position and a folded position. A resilient playing surface spans the frame and is foldable with the frame. A plurality of legs are each attachable to the arc connectors and hinged arc connectors. When legs are attached to the hinged arc connectors, the hinged arc connectors are locked so that the frame is locked in the flat position.
