Non infinity cube

Non infinity cube is a clever mechanical puzzle that was invented over 40 years ago by Vladimir Krasnoukhov. Originally called “Emelya’s Stove,” the name draws from Russian folklore (though the cultural reference doesn’t easily translate), hence its English name: the Non-Infinity Cube.

There are several challenges (24) that consist of symmetrical shapes to make by folding the cubes in some specific ways. So you really get a lot of puzzling for your money.

I found it pretty pleasant to play with the puzzle (it has a fidgety aspect) and even if you cannot make the official required shapes, well I guess you can find some as well and create your own challenges!

 
Making the required shapes is not that easy (nor it's overly difficult), it took me many moves including false progress (aka going back to the initial state...) to achieve some. I still need to work on this puzzles to achieve all the official shapes.

I have a small concern as the puzzle is entirely made with 3D printers (even the hinges): no force at all should be applied to the cubes. If you cannot fold a cube, don't insist or you will break the puzzle. And for this, maybe it's better to avoid letting children play with the puzzle (or consider a certain age above which it's ok).

By the way, I need to figure out something: on each side of each dice we can see dots like on real dice. But the challenges are only about shapes. So either there ar emore challenges for which you need to have one dot on one dice close to two dots on another dice. Or it's just to help you for the solution (or give hints) if any solutions exist...

 

I really like this puzzle. Well I usually like when you have many challenges for one puzzle and I always like building games. So if you're like me, I am sure you will enjoy it.
