Position Sums Sudoku
This puzzle can (of course!) be solved without any trial and error, but contains a few tricky steps.
Inspiration for this type comes from Donut and Chicken.
Solve online in Sudokupad (thanks sisk0!)
For those interested, after 10 years, I finally updated my
User page.
Apply classic sudoku rules.
Digits in the first and second cell from the top and from the left are A and B. Clues outside the grid tell something about A and B:
The sum of A and B is the closest to the grid;
The sum of the digits on positions A and B from that side are also outside the grid, in the grey bar.
Solution code: Row 5, followed by column 7.

Thanks for all the kind words!
All in all it seems to me that this puzzle is one of the highlights of SVS then. Didn't expect that in advance. :-)

Seemed hopeless at first, but opened up bit by bit.
