Black and Blue I
(Published on 2. August 2026, 19:00 by Tingo)
I'm back! Been a while since I've set (or even played) a sudoku puzzle. Inspiration struck for this black and blue idea tonight and I just had to put something together. Hope you all like it!
The rules are as follows:
Normal Sudoku rules apply
Cells joined by white dots are consecutive in value. Cells joined by black dots have a value in a ratio of 2:1. Not all dots are necessarily given.
Cells separated by a knight's move (in chess) cannot contain the same digit.
Cells connected by blue squares have values separated by 2. Example: a 3 may be next to a 1 or 5 but no other values are valid. A 4 may be next to a 2 or a 6, but no other values are valid.
The puzzle can be played at F-Puzzles here!
The puzzle can be played at CTC here!
Questions, comments, concerns and jokes are all welcome! Thanks for playing!
Solution code: Row 9, left to right
