Green Arrows
(Published on 14. December 2021, 17:31 by ExFalsoQuodlibet)
Normal sudoku rules apply. In addition:
- Green Cells: If a cell in box N is green, then the digit in that cell is the number of boxes in the completed grid which have N in the same position as that green cell. For instance, if R1C1 is green and contains a 2, then there are exactly 2 boxes which have 1 in the upper left-hand corner (because R1C1 is in the upper left-hand corner of box 1). There is no negative constraint; not all possible green cells are necessarily given.
- Arrows: The digits along each arrow must sum to the digit in the circled cell. Digits may repeat along an arrow if permitted by other rules.

You can try a slightly easier puzzle which uses the same 'green cells' constraint here.
Solution code: row 5 followed by column 5

I almost forgot the negative constraint in the end. Nice puzzle!

Really enjoyed this, had to be careful though, it's easy to slip up. Thanks for setting :)
