I’m thinking about trying my hand at the first puzzle in the Pentarasus Series if puzzles. All of the puzzles are level 10 and are rumored to be some of the most difficult in the world. Each has a key inside which helps you along the way to a real world puzzle which can bring in real money. If you are interested in checking them out start here! If your a more visual person here is what it looks like.
I think that idea that the puzzles unlock a greater puzzle is neat and I think they would look great in a display case with some of my other puzzles. Anyone want to join me in the quest to open this little devil?!
