{7,3} F0.4:0:1 F0.8:0:1 puzzle solved!
It is hyperbolic equivalent of "gigaminx" - there are two layers of rotation at each face. Method of solving is almost the same: I start with "subedge" 1-color pieces, then combine pieces at each edge, solve puzzle like classic Klein Quadric and at last put "subcorners" to correct place. Most problems are with the second stage - there are 84 edges, and it’s very difficult to find parts of the same edge. I did it by collecting all edge parts with some color around one center and working with them (nice feeling - when you can freely rotate almost all faces and know that you will not spoil anything by that).
Total twist count - 7558. Maximal operation length - 24 (for rotating 3 corners on the third stage), other operations are not longer than 8 twists.

Yeah, awesome!



Looks like another crystal cube order may be happening :D

{10,3} 18C F0.67:0:1 solved. 2680 twists.
It was easy enough (if you know how to handle pieces with wrong orientation).

 I’am playing with MT hyp {10,3],18C F0:0:1(not F1:0:0). 300 twists for 4 of the 18 colors so far. I don’t care for the number of twists and use 3 cycles all the way even early in order to not disturb anything. I also complete colors before starting a new one. So this puzzle is not so hard to solve but funny.


I will complete wiki for the 60 new puzzles and effectively aim for the new 50%.

May be, but in 120-Cell you have some search tools. In 36-color tiles there is many similar colors that makes difficult searching of the correct tile (even when you make one face white and all others dark). Pieces of F1:0:0 are very thin, most of them are close to boundary, so you don’t even see them all.
Topology of {10,3}, 36C is not very easy (actually, I don’t understand it at all). When I look for the tile, I’m not always sure that my search covers whole fundamental area, so I can go over the same part again and again. And there are problems with finding a way for tiles that doesn’t disturb already solved parts.

What about it is difficult? I would guess that more colors makes it more tedious but not harder, similar to 3^4 versus 120-Cell.

I’ve solved {10,3}, 36C, F:0:0:1. It was difficult - it has too many colors. Total count is 2518 twists.
