Unique Sum Sudoku
(Published on 13. September 2023, 05:05 by I Love Sleeping)
This puzzle was made with Myxo. Enjoy!
Rules:
Non-standard 4x4-Sudoku rules apply. Fill the grid with digits 1-9, such that no digit repeats in any row, column or box. The set of digits in each row or column is unique, eg. if a row contains the digits 1234, no other row or column may contain that combination of digits.
The digits in every row, column and box sum to x, where x has to be determined by the solver.Normal XV-rules apply. Digits separated by an X sum to 10. Digits separated by a V sum to 5. Not all Xs and Vs are necessarily given.
Solution code: Column 1, than Row 4, than the unique sum of the puzzle (10 digits, no spaces)

A lot of fun if you're looking for something different! Disagree with Ragna -- there's nothing here I'd call bifurcation, but thinking carefully about how to do coloring/labeling is crucial.

This puzzle is so amazing. I absolutely love it.
No bifurcation needed to solve.
