This puzzle is a work of a great mind and too those who can't use their mind and solve the puzzle without instructions should not buy because I'm guessing your IQ is extremely low.

Maybe my favorite of all time puzzle, for now at least. Put a 20 cent euro coin into and try to take it back. For that you have just a key. It is very well done, feel very strong and the way to open it is not straight forward. My favorite type of puzzle is sequential discovery and this one could have been a really interesting step of a much more complex puzzle le this type where the key and the coin would have been tools found during the rest of the solving. It could be also fun in parties to do some bet of 20 cts that people can't open it.

Very simple, does not belong in 8 category. I'd give it maybe a 5.
