I have managed to solve the first snake with 11 straights, but not the second. Can you give me a clue - just the ends. Corner/Face. It seems rather odd that there is a "C" next to one end.

I wrote the article "Solving a Generalization of Rubik's Cube" for the Journal of Recreational Mathematics back in the 90's.
I'd like to get have a Pyraminx Magic Tetrahedron and an Octahedron that work on the same principle (not the Trajbers construction). Does anyone have 3D-printer instructions to build one?

I had two flipped edges on the 3x3x3 Trabjer's Octahedron and it was driving me crazy. Thanks for the solution.

Hi Jaap,
I have been solving my Revenge cube using your "pairing up edges" method and have sometimes hit both parity problems i.e. swap two "edges" and flip an "edge" at the same time. You provide separate sequences for each but is it possible to find a single sequence to correct both in one step?

I just put one of these puzzles together on my kid's WII. I remember playing with these when younger. I hated them... but where is a will, there is a way! Thanks for the info! I wonder what it was called!

If the rubik's domino puzzle is anything like domino's pizza then it's pretty good.

Hi Jaap
I have a Rubiks Master edition that is stuck in an L-shape after a 7 year old got to it. I've spent hours trying to untangle it with no luck. Can you offer any clues as to how to untangle it? Many thanks.

Congratulations on writing a program to find all possible 3x3x3 snake cubes. I had wondered how many there could be and tried to devise such a program. My only thoughts would have meant an enormous amount of iterations (factorial 27). I wonder how you did it?

My friend, your web is really incredible. I can't believe that a single person could offer such a giant amount of information. Thank you very much, from Argentina! By the way, where are you from?

I have an original Trillion Puzzle (vintage, original, super sweet!) for sale on ebay right now. It's only at twenty bucks thus far. It's an original and is in GUC: however, there is some writing on the bottom. This is is the only flaw other than some minor scuffs on the plastic lid. GOto ebay and search Trillion Puzzle and my auction is under Earlenebean.

As with so many older puzzles, the only way to get one is by looking at auction sites like eBay, or by being lucky at a car boot sale or garage sale.

Hello, I found your website, as I was looking for the Luminations triangle shape lighted toy, that you have answers for the different levels, wow! I was wondering if you know where I can find one, as I have one but one of the connectors is corroded, help! Thank you very much for any assistance. Karen

I am researching the Rubix Sheet Master edition (silver, 2x6, rainbow rings) for a school project and im wondering if you have any affliction with rubix or information for me. It seems that the oriental looking logo on mine is not helpful, and rubix.com isnt either.

thanks!

Dear Jaap,

I have a small comment on your strategy for the `Face-turning Octahedron', phase 3: In order to arrange the centre pieces, I use (UFUF')^6. This algorithm brings the centre piece on the L face, r layer to the U face, and it brings the centre piece on the U face, l layer to the L face. It does not exchange the named pieces but does not affect corners, edges and centre pieces on other faces (and it leaves the other centre pieces on the L and U faces on these faces). I prefer this move because I find turning middle layers more cumbersome than turning sides.

Best wishes, Juergen

I got my boyfriend a qj super square one puzzle cube. He is having the worst time trying to solve this. I looked through all the cubes you have on this site and you do not have it. If you this cube up or find it, can you email me?? I feel bad about getting a cube that he can not solve!
