You control a small ball with your mouse, rolling it along thin black lines against a white background. Your goal is to guide it to the exit in each level. To do that, you interact with the machinery drawn on the screen. You click and drag gears to rotate them, which shifts the pathways. You also click on circular switches to activate them, changing which lines are solid and which vanish. The game gives you time to think; it's not about speed but about seeing the connections. The challenge comes from figuring out the sequence of turns and clicks that will create a continuous route. It feels like quietly solving a mechanical diagram with your own hands.
