Newton's egg

A nice puzzle designed and made by Stephen Chin, this Newton's egg obeys to the 3rd Newton's law.

The wood choosen is very nice and stand up on a nice display. Well for this kind of puzzles, you'd better have a display stand :-)
The cuts on the eggs are nicely made and look "real".
 

Like all or almost all Chin's puzzles, this one is not super difficult but will still puzzle you a bit of time. And like all his puzzles, the mechanism is not super complicated, but very efficient and well designed!

So far, I have not seen such a "mechanism" implemented in a puzzle and I liked a lot the way of solving it. And it's easy to repeat!

This is an egg(cellent) puzzle :)

Genie bottle

Designed, made and exchanged by Stephen Chin at IPP 2017 in Paris, this wooden puzzle has something similar that you can see in other Chin's puzzles: the wooden circles and the wood turning that he is famous for.

The goal is to open the puzzle and get your reward.

The puzzle has several steps, not unique mechanisms but all the steps are well implemented.

From the picture above there is one wooden ring with something special, maybe this is useful to solve it? (false question, I already know the answer!)

As all Chin's are very difficult to get (especially because he does not make a lot, and does not run a puzzle business), I am very please to have it. Not difficult but nice puzzle.

On the top of the puzzle is something special. Do you think using it will make the genie appear from its bottle? I am sure you will need to use the reward after ;-)

Ze chinnyhedron

Here is my first review of a Chin's puzzle!!

First you noticed the strange title, right? ("ze" instead of "the") and the name "chinnyhedron". Well, all the puzzles from Stephen Chin have a strange and pretty funny name. Maybe to remember them more easily?
A chinnyhedron is just a solid...or a strange geometrical solid made by Chinny (one of the several nicknames of the designer!) which goal is "just" to disassemble the puzzle. Easy? Not so!

The first difficulty is you have to put your fingers on the right pieces and there is no hints where you have to push/pull the pieces. So actually if you have 3 fingers pushing, maybe you're pushing 2 in the right direction but you're making the wrong move with the 3rd one, resulting in doing nothing :-)

So even if you have only 2 pieces to separate, well this is pretty challenging for only 2 pieces!!!

The puzzle is made even more difficult that the fit is pretty tight (too tight in my opinion, but maybe a bit less tight would make the puzzles disassemble by itself?), so you have to PUSH/PULL and not only push/pull, you get it?

Stephen Chin created other geometrical solids with the same goal but not the same number of pieces, hence several levels of difficulty for puzzles that looks the same!

I feel this is a pitty that the design does not release more of his puzzles and does not sell them. Sure it's not his job and more a hobby, but I am sure many people would like to enjoy his puzzles.
Stephen if you see that, make some more puzzles please!!! :-)
