OK I assume you all know the Hanayama's famous cast puzzles composed of usually (but not always) 2 pieces to separate and then to reassemble.
This puzzle is also a cast puzzle but does not belong to the "official" list of the cast puzzle series because it's a special and limited edition (hence the price is more expensive than the usual price of cast puzzles).
Designed by Oskar, this puzzle is composed of 2 rings that rotate creating a maze and a "tray" composed of 2 parts that you can push and pull.
So you're facing a 2 sides-maze: you have to move a disk, then push/pull the tray, move the other disk, etc. You need to anticipate the next moves depending on the path of the maze.
My technique to solve was was to look on both side each time.
But don't get me wrong: this is a difficult puzzle. I don't really know the rating of the difficulty as it's not written on the box but I would assume at least 5/6. You can be easily lost and make useless moves!
It reminds me kind of the other cast puzzle called L'oeuf, but I have some difficulties with the previous one as the moves were not super smooth and some slight force was needed. For this medallion puzzle, no force at all is needed, the moves are very smooth!
I even found another challenge with this puzzle!
I did not reassemble the puzzle in the "proper" configuration, resulting in a puzzle with the writting on the top with the flat side of the tray pointing up (come one, it's not just about rotating the whole puzzle hahaha!). If you look well on the first picture I put, the writting was at the bottom.
Who's up for this challenge??
In my mind, this is a really nice addition to your collection and definitely a must-have if you like (like me) the cast puzzles.
Being a special edition it's not available everywhere. I advise Brilliant Puzzle webshop to buy it. They charge the lowest price (compared to other webshops) for this puzzle!
Plus they offer a big range of puzzles. No doubt you will find something suitable for you! :)
