Search 8 or 9 sudoku
(Eingestellt am 1. Oktober 2023, 14:12 Uhr von Qodec)
- Sudoku: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Search 8 or 9: A digit in an arrow shows the distance to a cell containing a 8 -or- 9 in the indicated direction (not necessarily the 8 or 9 closest to it), with 1 pointing to the cell directly adjacent to it. Not all arrows are necessarily given.
An example 6x6 sudoku with the same ruleset, except the digits searched for are 5+6:

I am not great at detecting uniqueness tricks, so I actually didn't manage to spot that. Enjoyed it (all the more) anyway.

This was really fun. Such a great twist on a familiar constraint!

I didn't mind the uniqueness "issue". I think most solvers will probably see it, but it's really up to you if you'll use it or not. Liked the puzzle a lot. Smooth and nice solve path (even without taking the uniqueness shortcut). Thanks :-)
