This is number IV in the Karakuri set of “New Secret Boxes”. The solution is very different to the previous three versions and they say the hint is “Binary” and very difficult!
It takes 32 moves to open this the New Secret Box IV. Quite difficult by anyone’s standards.
All 6 surfaces of this box must slide in a set combination to allow this box to be opened. And you need to remember not for force anything. Just because you previously moved one panel, if you moved other panels since that panel may not move again. I’ve taken a picture with the box open. It won’t give away any clues on how to do the puzzle but you can see the very complex mechanism, all built from wood, that it takes to create this puzzle box. The panels of this box are slightly thinner and therefore perhaps slightly less robust than others in the New Secret Box series.
We have sourced these boxes directly from the Hakone (also known as Puzzle Mountain) region of Japan. The area including the town of Odawara where the Karakuri workshop is, has a long history of generations of master craftsmen making secret opening boxes for more than 100 years.
Our stock of these boxes is limited and once sold we’re not sure how long it will be before we could get similar puzzle boxes again.
This very special puzzle box with decorative strips of contrasting coloured woods on all six sides beautifully inlaid. The box is made from Walnut and the inlaid with other woods.
Size outside: 80mm x 80mm x 80mm There is a small space inside measuring 29mm x 29mm x 35mm and you could put something in there. It does not appear to impact the mechanism when you’re solving the puzzle.
The puzzle is cellophane wrapped and comes with a small solution sheet as in the photo.
