The Last Hurrah?
(Published on 2. August 2022, 07:17 by Playmaker6174)
Despite the extra clue in the grid it's still "technically" full ambiguous anyway. Estimated difficulty is in the range 4-4.5, but can be lower depends on how fast you understand the main ideas, I hope you enjoy!
Will I return to setting? Only time will tell, but I'll still be here solving...
- Normal Sudoku rules apply for the 9x9 grid: every row, column and 3x3 box contains digits from 1 to 9 each once.
- A ? clue outside the grid shows the sum of the first X cells from its corresponding direction, where X is the value of the first cell; a ? clue also shows the sum of two adjacent cells next to 9 in that respective row/column, in case 9 is next to the grid border, the sum is instead the value of the cell right next to it. The value of each ? clue is to be deduced.
- The white dot shows the consecutive relationship between two cells.
To demonstrate how the second rule works, for a row with ? clue, (?) 256749318 would be valid because 2+5 = 4+3 =7, or (?) 256431879 would be valid because 2+5=7.
Puzzle:
Good luck and have fun solving!
Solution code: Row 6 (left to right) and column 7 (top to bottom), 18 digits long with no space

I kept trying to submit my solution and getting frustrated because it wouldn't accept it, searching my grid for a contradiction and finding none... only to realize I had accidentally tried to enter the solution in kolot's puzzle hahahaha. Anyway I loved this! It's so minimalistic and was so fun to solve. The grid and ruleset are so simple and yet came together marvelously.

Very enjoyable, with a fascinating ruleset! I really hope you’ll feel the urge to set more puzzles again quite soon, but I guess I cannot really complain since I’ve failed to publish anything for half a year now, haha

Cool logic overall, and nice to see yet another new constraint ;)

Really an outstanding construction. Quite challenging at times but not nearly as brutal as I feared! I loved every step of it! :^) (Except the use of the white dot - seeing where that one came in was kind of heartbreaking haha)
Thanks for all the great puzzles you made so far, they really make up a fair share of my favourites on this site! Hope to see you return to setting someday if you're ever interested again :^)
