Another Mathematical Phenomenon

(Published on 25. September 2025, 01:10 by Xenonetix)

3 years on, I present the sequel to A Mathematical Phenomenon!



Penpa+ SudokuPad F-Puzzles

• Normal Sudoku Rules apply.
• Outside clues are Sandwich Clues, indicating the sum of the cells between the lowest & highest values (usually 1 & 9) seen in their row or column. R0C0 applies this to each of Row 0 & Column 0 individually.
• Apart from value 0, every Sandwich Clue is unique.
• Cells across White Dots contain consecutive values.
• Cells across Black Dots contain one value double the other (1:2 ratio).

(If multiple instances of 0 are seen by R0C0's clue, which is 'lowest' is to be determined by the solver.)

Here's a suggested way of marking outside numbers on SudokuPad & F-Puzzles:

Hope you enjoy! 😄 - Any feedback or comments welcome!

Solution code:

Row 0 (outside numbers, left to right, no spaces)

Added a new dot to help smooth the solve. Thanks to Quilty for the feedback (and it's incredible that wasn't addressed at all by any of the testers!)

This was really great! In the beginning I was like "how is this even solvable" but then it beautifully flowed through.

Very elegant puzzle! I got stuck on some basic sudoku at the end but the logic involved in row and column "0" was very nice!
