Hello.
Does anyone own a QUBAMI cube that cannot be solved with the method described in the thread "Review QUBAMI 3D SUDOKU (3x3)"? (page 3, posted by 'opi50' on 05-15-2015). https://www.speedsolving.com/forum/showthread.php?51096-QUBAMI-3D-Sudoku-%283x3%29/page3 , please see the attached pictures.
I developed this method while making my own QUBAMI puzzle coming from the 3D SUDOKUs. When I figured out, that there are only two possible configurations for a 3 color 3x3x3 cube with adjacent (same color) faces, I started thinking that the whole collection of QUBAMIs might only be a bunch of combinations of colors, symbols, and finally, only the two two possible 3D SUDOKU solves.
The parity cases, that need to appear because the 3D SUDOKUs have 3 triples of equivalent edge pieces just support the idea of a very difficult puzzle, because they are mixed again and again, also in the same puzzle. Also the challenge 5 has a little parity issue. But all these are not real "parities". They are provoked by the multiple equivalent pieces. And these multiple equivalent pieces remain the same for the 3D SUDOKU solves, where they are much more difficult to be identified than in the 3 color solve. Thus challenge #1 to #4 are basically the same. And knowing the pattern, the challenge #5 is the easiest solve.
I am sure that anyone can solve any QUBAMI with this solution guide within minutes, because they are all a combination of two superimposed, turned 3D 3x3 SUDOKU solves (same or different). But once having them identified, you just have to combine them correctly. That´s not a big deal.
I think, the only information required for the solution of a QUBAMI is the center scheme with their colors and symbols (R,L,F,U,D and B). That should be enough.
Best regards.
