Play Stack Fall 3D online For FREE! - Stack Ball Fall is an infinite 3d arcade game where you have to make the ball fall smash, bump and bounce through revolving helix platforms to reach the end. Your ball smashes like a brick through colorful platforms that block its descent, but if you hit a black one, it's all over! Your ball shatters to pieces and you have to start your fall all over again. But even black platforms are no match for a fireball falling at full speed! Choose your strategy: speed up like a madman or stop and wait for your next chance to roll and jump..
