I don't review that many Karakuri puzzle boxes so a quick review to change that :)
Ok so it's about the Dice puzzle box designed and made by Kamei
The six sides of the cube have the digit 1 to 6 like on a normal dice. Should you roll it like a dice to open it? I let you figure out if you have it :)
The design is super great and as you expect from Karakuri works, the craftmanship is top to none!
To be honest it did not take me long time to solve it (well, most Karakuri are pretty easy puzzles anyway!) but the solution is very satisfaying! A bit frustrating at the same time as you cannot see the internals nor the mecanism and I would have loved to see it :-(
The puzzle works reliably and you need to make the complete reverse steps to really close it.
Basically I closed it and performed some steps and I was surprised it closed the puzzle. Great but....it could be opened by performing another move. So make sure to completely close it before handling to someone else to try it. You don't want to spoil the puzzle at all I am sure.
Kamei is one of my favourite Karakuri craftmen and so, considering the design, solution, etc, I can only advise to buy it.
This puzzle is Available at Art of Play who offers a wide selection of Karakuri puzzle boxes. Time to start a Karakuri collection!
