The board tilts with your thumb, and the ball rolls wherever gravity tells it. Get it into the glowing hole and that's a point. Let it slip off the edge and a life disappears — three chances total, and the boards get steeper every time. The frustrating part isn't the ball. It's knowing exactly where you want it to go while your thumb over-tilts by half a degree and the whole plan falls apart. Then you get one perfect roll, dead center, and suddenly you remember why you started. One more hole. Just one more.
