## How to Solve the Professor Pyraminx

On Monday I received two puzzles in the mail. One was the Tutminx by Very Puzzle and the other was the Professor Pyraminx by Mefferts. The Tutminx is kinda crazy. It comes blank and requires stickering which is kind of fun. The actually puzzle itself is a bit annoying as you have to keep track of your turns as its easy to jumble the puzzle. If you jumble the puzzle up too bad the puzzle will cease up and certain face will not move.

The Professor Pyraminx was by far, way more fun to play with. After playing with it for a few minutes in the Post Office parking lot, I came up with a fairly decent method for solving the puzzle. It may not be the best or most efficient method, but it gets the job done. Here is how I solve the Professor Pyraminx:

You can really do this step whenever you feel like it, but I generally like to do this first. Just simply rotate the caps to align with the adjacent color. You do not need to worry about the global orientation of the corners at this point.

This step is pretty straight forward. Simply match the center triangles. You can use a similar style as solving the 4×4 centers.

This is where it starts to get a little tricky. You need to pair the 5 edge pieces together without destroying the center pieces. This can be easily done by using a similar style for pairing edges like the Rubik’s 4×4 or 5×5 cubes. I, personally, like to make pairs of two outer adjacent pieces, then sandwich the center edges later.

Now with all your pairs together, you can solve the puzzle like a skewb. Imagine the blue sections as the corners and the red areas as the centers. I would highly suggest learning how to solve a skewb before tackling this bigger puzzle. There are some odd scenarios that will come up due to the different orientation of pieces. Steps 5 and 6 deals with these special cases.

Occasionally an odd situation may appear where 2 edges need to be orientated correctly or “flipped”. You’ll see this case on the regular Pyraminx as well as any skewb mod that has a specific center rotation. Here is an algorithm that will solve this situation:

This is the last possible situation that you may encounter. Sometimes 1 or 2 of your tips will need to be rotated. This is pretty easy to fix using a “SUNE” type alg. Here is the algorithm for those unfamiliar with the “SUNE” alg:

And that should do it. As always feel free to post any questions you may have. I know my solutions are fairly vague at times but it helps if you know how to solve the basic puzzles prior to tackling larger puzzles like this. Good luck and happy puzzling!

Will you make a tutorial on the Vulcano puzzle? That I need help on.

Hi Steve, Thanks for the message, I will add it to my list.

Hey, I know this is ages after you posted this, but I just wanted to say thanks, I’d done all but 3 centres (I reduced how you did by myself), and couldn’t solve more. I didn’t realise it worked like a skewb.

Thanks,

Tim.

Thanks Tim! This is at least how I went about solving it. It might not be the most efficient way but it works for me, I hope it helps you too!

Regards,

Jake

I have two questions:

A) Say I have a case similar to the edge parity, but the two edges in question are swapped (blue edge on green face, green edge on blue face). Is there an algorithm to fix this?

B) Can you give and algorithm to swap two center edge pieces (the center part of the edge)? I think I need to apply a 5×5 algorithm, but I’m having trouble doing those algorithms on this puzzle.

Thank you.

i have tyhe same questions as steve im wondering if there is some sort of flipping algorithm or something to swich around to edge piece like on the 4×4 and others. thanks so much

I pretty much use the same concept as solving the 4×4 to pair up edges. Algorithms aren’t really needed for this step if you can already solve a 4×4. If you are getting stuck in this step, I usually go about pairing up the two inner edges first, usually along with the middle edge. Once I have those groups put together, I then move on to the outer edges. Use the same trick on the 4×4 to rotate edge clusters out of the way and bring in a new set to cycle. Here is a simple outer edge cycle: F U’ Rr U Rr’ F’. This move will swap Front outer Down edge with Front outer Up edge with BackRight outer Upper edge. Hope this helps!

Sorry for the major delay in reply. So far I can’t recreate a case where there are only 2 pieces that need swapping, these should all be 3 cycles.

hey, sorry if someone has already asked this question. I’m having trouble on step # 3, pairing the edges. I pair up the two inner edges first like a 4×4 and I have no problem there. But I’m stuck when solving the last two middle edges. I have two left and can’t seem to switch them!

Hi Jake, I’m not sure if I’m visualizing your case correctly but if you have 2 middle edges left that need swapping you may need to cycle your inner edge pieces according to the middle edges. This may require the use of two 3cycle algs. I hope this helps!

hey actually i figured out a way to fix my problem! It’s the same thing as one of steve’s problems. I realized when solving the middle edges it’s best to do all 3 of one color’s first, so then you can swap the last three. I was solving the middle edges at random which was giving me problems.
