This game is similar to the classic Atari arcade games Breakout and Pong — you need to keep the rock on the screen for as long as possible. Three sides of the screen are closed, and your platform is on the right side. The rock starts moving, bouncing off the walls, and you must prevent it from going off the screen using your platform. Your final score will be based on how long you can keep the rock in play. But remember, this game is not the easiest — give it your best shot!
