XY-Differences III
(Published on 14. July 2020, 02:12 by glum_hippo)
I've once again taken up the "XY Differences" idea. The following puzzle was submitted for consideration by CtC and first released on the CtC discord server.
Normal Sudoku rules apply.
If there's a diamond between two horizontally adjacent cells, then the absolute value of their difference is the same as the first digit in that row.
If there's a diamond between two vertically adjacent cells, then the absolute value of their difference is the same as the first digit in that column. See example.
Take note! All possible diamonds are shown. That is, if no symbol is given, then the difference does not correspond to the first cell.

And here is the puzzle (also available on penpa, where a completed, correct solution now triggers an alert):
Solution code: Row 4, then column 6 (18 digits total)

Thanks, CilantroGamer. I'm blushing! But I hope you'll find many comparable gems on this site. Welcome to LM Germany!

This puzzle is absolutely genius. The levels of logic required are insane. I got stuck twice, and almost resorted to bifurcation in both cases. I had to work a bit ahead in the first case, but in the second case some cleverly hidden unspoken constraints helped me solve the rest.
This is my favorite sudoku puzzle I've ever done.

Nice logic, but difficult throughout.
