Bumper Ball is a 3D arcade physics party game about heavy, bouncy player spheres dueling above lava. Roll with momentum, slam opponents, survive ring-outs, and adapt as the arena shrinks through solid, split-hole, donut, and star platform variants. Play solo with bot fill, same-device local multiplayer, or Photon-powered online lobbies with public Quick Match and private room codes. Rounds are fast, readable, and score toward a first-to-3 match win.
