The player's goal is to explore a world where a mysterious pin has jammed inside a complex contraption. Part of the goal is to guide a small metal ball through a series of interconnected tubes and rollers by rotating each pin.
By rotating each pin, the player must carefully navigate the ball to the end of the maze, all while avoiding obstacles and dead ends. To progress, the player must use trial and error, attempting different configurations of pin rotation to create a clear path for the ball to follow.
