Playing Around With Parity
1,332***Thanks to everyone who has offered to help with our Google PlayStore issue (our Thermo Sudoku and Miracle Sudoku apps have been removed because they are too "repetitive"). We are hearing that, due to your effort, the decision may be overturned and we're keeping our fingers crossed.***
Today's puzzle is another original and brilliant sudoku from Dying Flutchman. If you enjoy playing around with parity, you'll love this. You can play the puzzle at the following link:
https://app.crackingthecryptic.com/sudoku/hTHqF2DP3b
Rules:
Normal sudoku rules apply. In the finished grid, every cell will be part of a group of orthogonally connected cells that share the same parity (ie an odd or even group comprising every orthogonally connected cell of the same parity). Such a parity group can be as small as a single cell, or large enough to span multiple boxes and include repeating digits. Corner clues give the sum of all cells in the parity group containing that cell. Black dots separate cells with a 1:2 ratio. Not all possible black dots are given.
*** Botaku Bonus Puzzle ***
As mentioned in the video, we have a bonus puzzle today from the brilliant Botaku. It's called Euclidean Sudoku! You can play it at the link below and watch a video of Simon solving it on our Patreon page.

Rules:
Normal sudoku rules apply. Given two cells which both contain the digit N, the Euclidean distance between (the centres of) those cells must be at least √N times the sidelength of a single cell. In other words, if moving from one such cell to the other takes X horizontal steps and Y vertical steps, then √(X^2 + Y^2) ≥ √N.
