Smus-X
(Published on 25. September 2022, 14:44 by Qodec)
Two earlier puzzles with this ruleset:
- Reverse Sums by kuraban.
- Sudoku Variants Series (355) - Opposite X-Sums Sudoku by Richard Stolk.
- Normal sudoku rules apply: Each row, column, and region indicated by thick borders in the grid must contain the digits 1 to 9 once each.
- Opposite X-Sums: Clues outside the grid indicate the sum of the last X digits as seen from that side, where X is the digit in the first cell from that side. I.e. normal X-sums rule except the sum starts at the opposite side of the grid.
You can play this puzzle online using:
- CTC app (Sudokupad): https://tinyurl.com/4fc2dv9y
- f-puzzles: https://f-puzzles.com/?id=2enjpchw
Hope you will enjoy.
Solution code: Rows 2 and 5. I.e. the 9 digits in row 2 from left to right, followed by the 9 digits in row 5 from left to right, for example: 123456789123456789

Absolute brilliant puzzle with very, very clever chosen givens and a very rewarding solve path.
Found a few extremely nice and fun deductions throughout the solve.
Thanks for this gem! :-)

Very nice! I got hit by a curveball in the mid-solve, but it was pretty smooth regardless!

Loved the concept of reversed X-sums and definitely will try the puzzles that inspired this one. Tricky logic after midsolve, which made it even more interesting and rewarding. Thanks.

Lovely puzzle with lots of interesting deductions littered throughout! It fascinates me that this puzzle has quite a few clues, but they all made up for such great experience, and I love that ending there ;)

Gorgeous logic! Disambiguating the end must have been extremely difficult, it felt very precariously balanced :)
