*** TODAY'S PUZZLE ***
Another georgous sudoku tonight from Jonesy and a clever ruleset that'll get you thinking about parity. Oh and if you do want to learn more about the crossword Simon goes on a segue about halfway through the video, there's a link to it below too :)
Play the puzzle at the links below:
https://sudokupad.app/ujnp27j7ir
Rules:
Normal sudoku rules apply. On each line, the sum of either the odd digits or the even digits is exactly *half* or *double* the sum of the other parity. Additionally, all end cells of any line contain digits of the same parity (all odd or all even). Digits separated by a white dot are consecutive. Entering correct digits may lift fog somewhere in the grid. No guessing is required.
You can find out more about the crossword Hope by Pieman (Simon's crossword pseudonym) here:
