once again, i find myself being inspired by shye's great puzzles!

Code: Select all

...|2..|../
9..|47.|./6
8.4|..3|/..

3..|../|...
57.|./4|9..
..1|/..|8.5

../|...|1..
./5|9..|.7.
/..|8.6|..2

...2.....9..47...68.4..3...3........57...49....1...8.5......1....59...7....8.6..2

for those who manually solve like i do, shortly after i posted this, i found one with less tedious basics

Code: Select all

...|2..|../
9..|47.|./6
8.4|...|/2.
-----------
3..|../|...
57.|./4|9..
...|/3.|8.5
-----------
../|...|1..
./5|9..|.7.
/1.|8.6|...

...2.....9..47...68.4....2.3........57...49......3.8.5......1....59...7..1.8.6...

The first one needs lots of forcing chains, undoable.

Code: Select all

7 5 6 2 1 9 3 8 4
9 1 3 4 7 8 2 5 6
8 2 4 5 6 3 7 1 9
3 9 8 1 5 2 6 4 7
5 7 2 6 8 4 9 3 1
6 4 1 3 9 7 8 2 5
4 8 9 7 2 5 1 6 3
2 6 5 9 3 1 4 7 8
1 3 7 8 4 6 5 9 2

The second was nicer, only 1 or 2 forcing chains.
(no solution added for manual solvers)
I did not find the "less tedious basics"

needs?

6 in r8c7 gives the puzzle box symmetry, note the transformation from box symmetry does not impact the diagonal directly, but this would imply repeated 789 on the diagonal (where 9 goes for instance places symmetric 9s along the same diagonal)
given this has one solution, -6r8c7, and the puzzle solves with locked candidates

the second version is much smoother (stte)

Can you show a solution path?

It's provided in her message above, I believe.
