Cast Equa

This has to be (in my opinion) one of -if not the- best looking puzzle of the Hanayama Cast range. This is the Cast Equa:

This was the Cast puzzle that I wanted to get more than any of the others, mostly again because of how good it looks. And with it's solid metal construction, finished in dark colour chrome it really does look spectacular. I would've reviewed it earlier on but even though I got it for Christmas I only just managed to put it back together this morning! And I wanted to have a photo of the Equa in it's completed form for my review.

One thing that is kind of hard to tell from the photos is that the Equa is actually made up of three solid metal pieces and not two. The outer 'casing' of the puzzle is all one piece and looks the same from every angle, but the inner 'ball' of the puzzle is actually made up of two 'c' shaped rings that lock together to form a sort of sphere....thing. The inner sphere can be rotated within the outer part to a certain degree, but there are two small protruding areas on the sphere that stop it from being moved in certain directions.

I managed to get the Equa apart into it's three pieces after about 2-3 hours, and I thought it would take me much less to put it back together, but oh how wrong I was. I didn't pay too much attention to how it came apart, and because of that I wasn't really sure on how to start putting it back together again. So it took me another few weeks of fiddling with it on and off until I managed to put it back together this morning and take a photo of it.

Hanayama rate the Equa as a level 5 out of 6 on it's difficulty scale, which I think is actually about right, but it definitely borders on being a level 6. All I can say is pay close attention when it comes apart. You have been warned!

This puzzle was also bought for me (lucky me eh?), but it came from: Puzzle This. It is also available from Puzzle Master.

  1. Once I got to the position where the rings were giong to release I made SURE I paid attention. Well it was STILL tough! It's 8:30 pm here and I just finished putting it back together and I've been working on it off and on since 10:00 pm last night. GREAT puzzle!

  2. I wouldn't consider that a bad amount of time at all considering how difficult it is! Well done for solving it!

  3. Ok, I just found your blog because I am mildly frustrated and thoroughly entertained by this "Equa" puzzle. This is the first of Hanayama's cast puzzles that has elevated my frustration level. I am now on hour 6 (an estimate) and still haven't solved this little gem. My wife has asked me 3 times now why I am laughing out loud, and I keep telling her that I'm laughing at how frustrated I am getting. I find this puzzle much more difficult than "Chain", "Cylinder", "Square", "News", and "Nutcase". Maybe I'm just missing something, but I would rate this one a "7" on the 1-6 scale that Hanayama uses. It's a great one for sure. I think I may have to put it away for awhile and attempt "Quartet" that is sitting here in front of me waiting to be solved.


No puzzle spoilers please!
