Hanayama Cast Dial

Another fun puzzle from Hanayama! I love these puzzles that seem so impossible at the beginning, but slowly reveal the solution over time. This one was wonderful to solve and is very cleverly built.

At first, it just seems that there is no way to make any progress. There is a triangular frame that is made up of 2 pieces and an internal, rotating “dial” that is also made of two pieces. The only thing that stands out is that the 2 dial pieces have different thicknesses. But otherwise, there isn’t much to go on.

The 2 dial pieces can rotate independently, but it doesn’t seem to affect anything. Its a confounding situation to have a puzzle that seemingly has no entry points. Its also a bit frustrating, because there’s not much manipulation to be had here. A lot of Hanayama puzzles consist of 3 intertwined pieces, so you can at least fiddle with them and change positions – but with Dial, there just isn’t much to play with. You can flip the dial and turn the 2 half, but nothing else.

The first time I picked this up, I didn’t get anywhere. It just didn’t seem like there was anything to manipulate. But, as I resisted this puzzle later on, it came to me that I just had to work with what I got.

I noticed some subtle variations when spinning the dial – sometimes, the triangular frame seemed to loosen up a little bit. So, I played around with this for a while. The hard part here, is that it is difficult to grab the frame. I had a good idea on how it would open, but it was hard to apply  pressure in the right place. Eventually, I achieved the first move. It was glorious to feel this thing open a bit after a few hours of tinkering.

But, it wasn’t over yet. As I tried to open it further, I accidentally closed it again and had to start over. It was a bit of a bummer, but ultimately helped because the second time around, I was more aware of how it was working.

Eventually, I got the thing open and the internal secrets were revealed. Now, all the turning made sense to me as I could see how things worked mechanically.

The Dial has been opened. The backside of the dials hold the secret.

Reassembly was a bit tricky, but it also revealed to me more of how things work. Once everything was positioned just right, I was able to close the dial back up.

Overall, a very fun puzzle that was quite challenging to me.
