The Lighthouse Puzzle Solution
Not only does the lighthouse's light go around and around... What rotates and what does not is a key to this shiny brass frustration! And there is also a key to be found to help lock the rotation and remove the ring that circles the puzzle.
First, unscrew the bottom of the lighthouse.
Second, unscrew the screw from the bottom piece. This is the trick.
Third, use the little peg inside this hidden compartment to lock the top of the lighthouse in place. Do this by sticking it through one of the holes in the lighthouse and spin it until it catches. Now, you can unscrew the top.
Now, you can take the ring off.
