Japanese Sums Sudoku - with negatives
(Eingestellt am 4. September 2023, 14:33 Uhr von RockyRoer)
The Rules:
- Normal sudoku rules apply - fill every row, column and 3x3 box with the digits from 1-9.
- [Japanese Sums Sudoku]Shade some cells. Shaded cells will have to be shaded one color for positives and a different color for negatives. Clues outside the grid represent the sum of runs of shaded cells in that row or column, in order from left to right or top to bottom. An unshaded cell must separate multiple runs that have been clued.
The Puzzle:
Play on CTC Software - answer check on digits should work, but it won't check if positive/negative shading is correct.
Play it on Penpa if you'd prefer. Answer check on digits only, but not positive/negatives.
Lösungscode: Row 4's SHADED cells only -- include negative signs for negative numbers: ex 8 -2 6 7 -1 4 (?? digits) (spaces or commas aren't included in solution check, so feel free to use them to separate numbers if you'd like.)

Very fun puzzle! Quite easily to come up with a wrong logic though.

Fantastic puzzle! I had a great time playing around with all the parity-stuff and the JS-constraint, up to clearing the last deadly pattern. Thank you so much for setting and sharing this masterpiece.
