Reverse Sums
(Published on 15. November 2021, 18:15 by kuraban)
Normal sudoku rules apply.
Numbers outside the grid show the total of the X number of cells, starting the OPPOSITE side of the grid, where X is the first cell next to the clue. This puzzle is a variant of the X-Sums variant puzzle type.
Here's an example, showing how a 3, 5 or 8 might look as a Reverse Sum.
You can reverse your sums on f-puzzles.
Or, if you'd prefer, on the CTC App.
Solution code: Column 5 from top to bottom, followed by row 6 from left to right, with no spaces.

I finally solved it. Thank you for your help. In my head i mixed up the reverse-x-sums-rule with the regular x-sums-rule and made some mistakes.

I like the simple twist on the X-Sum. It's fun to discover the differences with the usual rule while the feeling of still being in familiar territory.
Thanks!
