Sudoku Variants Series (278) - Position Sums Sudoku

(Published on 22. July 2020, 00:00 by Richard)

For this Sudoku Variants Project I have planned to publish a different Sudoku variant every week. I will see how long it takes before I am running out of ideas.

Position Sums Sudoku
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.

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 Penpa+ (thanks glum_hippo!)

For those interested, after 10 years, I finally updated my User page.

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. :-)
