She designed and crafted a wooden puzzle "free the marble" which, as the name indicates, goal is to free the marble from the interlocking wooden pieces.
The craftmanship is very nice and precise, congrats for this nicely made puzzle!
Several steps are needed to solve the puzzle. First you need to disassemble the pieces, which is not that obvious because you cannot see how the marble intereacts with the wooden pieces. Sometimes it blocks any moves, sometimes a wooden piece can move it the marble is in the correct place.
Then when you have all he 3 pieces that move freely, you can think that the solving process is over. NOOOO!!! You still have a nice challenge which is not that easy. What is funny is that now you see the inside of the wooden pieces and you see the marble. Still, it took me pretty long time before solving completely the puzzle.
Guess what? The wooden pieces cannot be disassembled and that surprised me a lot. Maybe some more puzzling could have been even added with this challenge which would have consisted in separating the 3 pieces. And I am sure it's more difficult to craft 3 connected pieces than 3 separated pieces!
Not many of this puzzle were crafted and I am proud to own a puzzle made by a French person! It changes :)
I think this puzzle is a very nice idea for Hanayama cast series, and I am sure it will be successful. Let's see if Laurence asked them...
