Crux Puzzles

This should make a nice little stocking filler present for my son and keep him quiet for a little bit.

Great puzzle. I'd also liked a box. And a notification when new versions of the Hilbert Curve puzzle are available.

Well made and great activity just wish it had something to keep it closed when transporting a few of them!

Well made and beautifully finished box. New to puzzle box solving so this took a while for me to solve. Very happy with order and will be back for more.

I have never had any issues with the Quality of Hanayama puzzles. This is no exception. It weighty, well crafted and very tactile. As I have mentioned before on my reviews, I am not the world's best puzzler and still not solved it. I will not give up.

As usual the quality of the puzzle is very good. The puzzle is fiddly (in a good way) and very frustrating. My puzzling skills are not great and I still haven't solved it.

The Piston ll puzzle by Felix Ure is a beautiful piece of engineering. Its weight and size is guaranteed to impress and you won’t be disappointed with its inner workings as you attempt to solve it. If like me you have other Felix Ure puzzles you’ll want this one to add to them.

Beautifully made puzzle. Makes for a good challenge

This little puzzle is infuriating.......................just saying

The three Stomachion puzzles I have bought from you look to be very attractively and well made, and are well wrapped and presented. I shall not be giving them as presents to family members until Christmas, so this is all I can say now - except that it seems a pity that the colour white is used for some of the pieces. The large white keys seem somehow 'set apart' from the other keys, and the whole puzzle would be more appealing if the pieces were all made with 'proper' colours.....

I love Karakuri puzzle boxes, they are so well made!

The customer service provided by Crux is fabulous, Kyle went above and beyond, so grateful. Thanks guys!

Great little box love ir well made and finshed

Managed with some perseverance to solve it. Just need to put it back together again!

Bought as a gift, it arrived quickly, well packaged and would happily buy from you again.

Well worth the money great fun
