"Long time ago (probably already 20 years) I created the Yen Puzzle. It is a wooden frame with a nail in it that holds a Yen Coin from Japan.
Because of my upgraded new creation does have some other secrets in it, I thought it will be better to name it the Lotus (it sounds more mysterious:) Probably later on you will understand why. ... From one side of the Lotus puzzle you will see a small black pin. Please do not remove this pin. It is just there for your safety, it has nothing to do with the solution. Later on when you know the solution you may remove this black pin, to see the inner part of the puzzle. (Please, be sure you found all the secrets before you remove the black pin :)
No magnets, no bang, no external tools, no force in any way. Just enjoy and found the secrets of the Lotus Puzzle." -Wil Strijbos
