The puzzle is a sort of carnival game where two players are balancing a board with two ropes attached to a pulley system. On the wall behind the board, there are several holes with animals next to them. The goal is to balance a rock-looking ball to the correct hole through cooperation and guidence from a third player.
A player enters the room with an animal on a screen, communicates silently through charades to guide teammates to the right hole, and then they repeat this process for multiple rounds, striving to hit all the different holes in the correct order as fast as possible.
