Sudoku Pad: sudokupad.app/h0gryo0v6v
Normal sudoku rules apply. Place the digits 1 to 9 exactly once in each row, column, and 3×3 box.
The 9th Symbol:
The cell at the center of the grid (r5c5) contains The 9th Symbol. Its value is a digit from 2 to 9, excluding 1! The exact value must be deduced by the solver.
German Whisper Lines:
On any green line, adjacent digits must differ by at least 5.
Region Sums:
Box borders divide the green line into regions. The sum of digits in each region must be a multiple of The 9th Symbol.
Ie: If The 9th Symbol is 9, Cells r1c2, r2c3, r3c2 must sum to 9, 18, 27, et cetera.
Knight Move Constraint:
No two identical digits may be placed in cells that are a knight’s move apart (as in chess: 2 by 1 move in any direction).
Lösungscode: Row 1

Couldn't figure out this one at all. Made an educated guess what the 9th Symbol was and filled out the whole puzzle. Now Imma go back and see if I can figure out why it had to be that ^_^

The break in for this was beautiful, the puzzle went from almost no progress to a "How did I not spot that sooner?" moment and the rest came together from there.
4* break in, 3* puzzle. Thank you for the experience!
