The point of the puzzle is to vanish the domino tile platform by matching pip squares on the upper platform above you, but as there are multiple combinations of pips it can be quite tricky. Pull the lever to reset the puzzle if needed. Upon arriving at this location you will find a Domino piece leaning up against the wall. You will be teleported to the puzzle up in the air once you click the domino. Once your ported look up. That is your puzzle. You must highlight each domino. Upon highlighting the domino the tiles in the center will vanish. Be sure to move around the puzzle, but be careful if you fall the puzzle will reset. Its a little hard to reach the pieces in the center of the puzzle from the outer edge so plan carefully. Upon successfully highlighting the entire puzzle in the proper way you will receive a key. Use the key to loot the chest. Upon looting the chest you will earn the achievement "Going Dotty." Congrats the puzzle is complete.
