Binary Controller
(Published on 24. June 2024, 19:53 by Maximus)
Normal Sudoku rules, but with numbers 0-8.
Binary cages: Color digits by parity. The resulting colorpattern in a cage represents a binary number X. For this purpose odd numbers are 1, even numbers 0. The number X is the same as the sum of the (decimal) digits in the cage. (Example: 1345 would be valid for a cage of size 4, because 1101 is binary for 13, and the sum of 1345 is also 13)
Control lines: Digits on a line sum to an even number AND contain no repeated digits.

I've been playing with the idea of using parity as a binary code for clues. I used the numbers 0-8 to get more options for the cages. The control lines are a form of parity-check, often used to verify a binary code.
Enjoy the puzzle!
