Parity sections Sudoku
(Published on 25. May 2020, 08:35 by stephane.bura)
Normal Sudoku rules apply.
A number in the lower right corner of a cell is the sum of all the cells in that cell's section.
A section is a group of orthogonally adjacent cells of the same parity (even or odd).
Every even section is orthogonally adjacent to the gray cell.

This puzzle deserves more solves! It is fun and definitely not as hard as the current number of solvers suggests!
If I may give a hint: use Excel and colours to mark cells. More is not necessary... Enjoy!

And yet another idea on my list for SVS. This list has grown pretty fast in the last few months! :-)
Nice puzzle!

Changed difficulty. Apparently, it's harder than I thought ;) I want to reassure you though that there *is* a narrow logical path to the solution.
