Odd Region
(Published on 20. December 2020, 20:50 by polmanpoppins)
Rules: Standard sudoku rules apply.
All odd numbers lie in a single orthogonally connected region.
Circles indicate the total count of cells of the same parity (either odd or even) connected vertically and horizontally to the numbered cell including the cell itself. Like in cave puzzles.
Diamonds show the number of orthogonally connected even numbers including itself.
An example region with a circle and diamond is shown here:
Solution code: Row 2 and column 7

I was initially intimidated by the ruleset, but this was a very nicely flowing puzzle from beginning to end. I'm glad I got to solve it.

Loved the Even-Odd ruleset and the logic.
And the finish was great! Even-Odd puzzles tend to have a rather boring end. But not in this one.

Thanks for the feedback MartinR - I've updated the labels as a result (and added that circles are like cave puzzle clues). Glad you liked the solve!

Nice solve, although I initially misunderstood the circles (though they were sweeper type, rather than cave like)
You may also get more solves if you add the
"Sudoku" tag so it appears in the correct lists - I cam across this through the " No Sudokus" queury :)
