SixyExplainer - to solve and rate 6x6 SixySudoku puzzles

Postby 1to9only » Tue Dec 10, 2019 10:22 am

SixyExplainer is my modifications to Sudoku6x6Explainer to solve 6x6 SixySudokus.
SixySudoku is 6x6 Sudoku with an additional constraint, the numbers 1-6 must appear exactly once in each row, column, 2Rx3C block (white and grey areas) and 3Rx2C block (black outlined areas).
SixyExplainer does not solve SixySudoku puzzles where the 4th constraint is irregular jigsaw cages.
SixyExplainer can be downloaded from here.
Usage is same as for SE.

SixyExplainer was done over a year ago. It has been downloaded a number of times. Dont know how much use they get solving Sixy Sudokus. The sudokus from the (free) Sixy Sudoku App from https://sixysudoku.com are mostly Easy ones solved with no pencilmarks, with some of the harder ones maybe rated at most ED=3.x.
No new release is currently planned!

I think adding Generalized Intersections to SixyExplainer will result in some puzzle ratings being lowered, e.g.
Code: Select all
1....4.5..1..........3....6...53...6 SIXY  9 5 ED=7.0/7.0/2.6 -> new rating ED=2.9/2.9/2.6

Image
Code: Select all
2.9, Generalized Intersection: Cells R5C1,R5C2,R6C3: 2 in block: -2r5c4
2.9, Generalized Intersection: Cells R5C1,R5C2,R6C3: 4 in block: -4r5c4

By manual solving: R5C2,R6C3: 1 in block: -1r5c4
Which leaves a 5 in cell r5c4. So 26 in r12c4. So a 3 in r2c6. So 5 in r1c5....
Generalized Intersection is indeed an enrichment. But is a 2.9 rating sufficient or too little value?
