Running Out of Ink
(Published on 19. January 2026, 21:18 by Swevik)
Normal Sudoku rules apply.
German Whispers:
Adjacent digits along a green line have a difference of at least 5.
Palindromes:
Digits on a red line read the same forwards and backwards.
Region Sum Lines:
Box borders divide a blue line into segments with equal sums. Different lines may have different sums. Lines must cross at least one box border.
Oops, my printer seems to have run out of colour ink! I'm sure you can figure out what each line is!
(Each grey line obeys exactly one of the three listed line rules.)
You can play it on sudoku pad. (The pen tool is useful!)

Had to change the type of one line near the end as I messed up.
Nice puzzle though.

I loved this! There was a lot of fun logic to figuring out what sort of line everything had to be, and it was an easy but fun solve from beginning to end!
