Sudoku Variants Series (448) - Coordinate arrows
(Published on 31. October 2025, 06:00 by Richard)
I will see how long it takes before I am running out of ideas.
Coordinate arrows
Inspiration for this type comes from Piatato.
Solve online in Sudokupad or in Penpa+.
Apply classic sudoku rules.
Digits on an arrow spell out the coordinates for the digit that is the sum of both digits on that arrow. The row number is written on the tail of the arrow, the column number on the sharp tip. (-14-> gives a 5 in R1C4.)
Every arrow contains different coordinates!
Digits may be repeated on arrows.
Solution code: Column 3

Rather relaxing, actually. It was nice to watch the color I used for "can't be pointed to" gradually overtake the board.

A wonderful introduction of this unusual constraint! Maybe I should try to solve Piatato‘s original puzzle now? Thank you very much for creating and sharing.

Great fun, smooth and elegant solution! I always enjoy seeing this ruleset in use, it seems to always lead to really nice puzzles! Also, I would be remiss if I didn't point people toward 00095K, which is an awesome coordinate arrows sudoku, created by Aaronymous, the main inventor of this ruleset. :)

Pretty much as approachable as a coordinate arrow puzzle can be. Do give it a go
