XY-Differences II

(Published on 22. June 2020, 00:50 by glum_hippo)

I've once again taken up the "XY Differences" idea. However, this time (1) the parity clues were no longer needed and (2) I've managed to achieve a more symmetrical layout of clues. Hope you like it!

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.

If no symbol is given, then the difference does not correspond to the first cell.

And here is the puzzle (also available on penpa and here in SudokuPad):

Solution code: Rows 8 and 9 (18 digits)

Very nice puzzle!
This one deserves
a) more solves because itis a very nice one and
b) a much higher rating because it is a very nice one!
:-)

The rating system is very capricious, and I don't focus on it much... but I can see now why 0003P8 was better appreciated, as a solving experience. Thanks for your kind words.
