Just got this puzzle today and haven't seen any posts about it:

It reminds me a little of a cross between the Columbus Egg and the Pakovalec and is a pretty nice puzzle that's not too hard. You twist the tube and depending where the "buttons" are the numbers moves or not. The aim is to line up all the number 1's, then the number 2's etc and there is also a 6 number Sudoku box to be made.
Here is the website (they are looking for some help from the mathematicians out there and there are also some virtual examples to play in different difficulty levels): Sudoku Tubie

mind giving us a little more info por favor?

There is lots of info when you click on the link.
I want this puzzle !!!

What he said! - if you want some specific info about the puzzle then let me know what it is that you want to know and I'll be happy to help out if I can, otherwise I'm not really sure what to add to my original post.


I do have a second one if anyone is interested!
