Dismay (Region Sum Lines Sudoku)
(Eingestellt am 29. Juni 2022, 22:50 Uhr von Qodec)
- Normal sudoku rules apply: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Region sum lines: Blue lines are region sum lines. The sum of the digits on a line within a particular region must be the same for all of the regions the line passes through. The sum applies to each individual visit a line makes to a region. Different lines may have different sums.

Thanks, some sublime deductions to be made. Can't recall a more stubborn puzzle, it kept refusing to collapse. Perhaps I missed something.

Region sum lines, but I don't think the logic is remotely similar to anything I saw before. It was a brutal puzzle, but very beautiful.

Beautiful designed "expressive face" sudoku ! Lovely break-in and a bit of struggle for me near the end to find the "weak cell" that disambiguates the whole thing. Thanks.

Beautiful design and some sneaky deductions in there, got some trouble in the later half but luckily my scanning abilities hit that soft point :)
