"Cast News" is a wonderful puzzle. Consisting of only two identical pieces, it is rated by Hanayama at level 6 (out of 6). Which means that despite the two pieces, it is very difficult to solve. Well, unless you are already familiar with the concept or are very lucky. To be honest, the first time you will indeed need some luck in order to separate the two pieces. After that, if you examine the inner structure of them, you have the task to find out how you can solve it faster and why the potential solution would work every time. Yes, it takes less than 10 seconds to separate the two pieces once you know the trick behind.
I myself did not manage to find the correct solution. I had something and thinking it is the true one, I checked on the internet if I was right. Well, I was not. This is one of the puzzles which I failed at. And it made me feel not happy with it, resulting in this puzzle not being in my top favourites. Most of the others I have, which I have failed at, are my most favourite, but not this one. I don't mean that I don't like it, I do, but not that much that I can boast with it. Don't get me wrong - I think the idea is more than great, the solution is very knowledge-requiring, the design is very precise. It's just not in my heart, if you know what I mean.
Mentioning design, there is something I noticed and it is worth sharing. If you have not seen it yet - it would be nice to know it. The puzzle is called NEWS, which has an anagram EWNS, which stands for East, West, North and South. These are situated on the surface of the puzzle in the corresponding order. So, if you need to know if you have put it properly back together, just take a look at the four directions and if they are displayed correctly. Not that you cannot put it back wrongly (WENS), but it would not make sense and will not be that nice.
Associating the puzzle with the four directions of the world, when I was trying to solve it the first time, I thought there is something like a compass inside, which, when pointed to north, would lead to position of the inner structure that allows separation of the two pieces. Well, I was wrong, but I think such an idea for a puzzle would be great, wouldn't it?
With all these, I am giving "Cast News" the following ratings:
You should have this puzzle is your collection as the idea presented is very popular and a must-know.
