The game features Professor Rat, a character who is passionate about physics puzzles and experiments involving robots. He has created a robot named Robby, but has given him a weak battery, necessitating constant recharging and participation in the professor's innovative experiments. The objective is to interact with various physical objects to guide the robot Robby through all of Professor Rat's puzzle rooms and free him from the charging station. Additionally, the game offers a Level Editor, allowing players to create their own intriguing puzzles.

On a PC, use the left mouse button, or on a mobile device, use your finger to pop, destroy, or move game objects. Place the square robot Robby in the red charging station to complete the level.
