Parity Party 1
(Published on 5. December 2025, 23:44 by galium_odoratum)
Normal Sudoku rules apply.
Odd/Even cages: Digits in a cage with an E sum to an even number. Digits in a cage with an O sum to an odd number.
Global odd/even: Each 2x2 area contains digits of both parities (odd and even).
Thermometers: Digits along a thermometer strictly increase from the bulb end.
Kropki: Cells connected by a white dot must be consecutive. Not all dots are necessarily given.

I did start again having forgotten the 2x2 rule but then it flowed very nicely. Time for another one as I do like colouring puzzles!

Oh wow, this felt very hard.
80 minutes until the first number! But then only 12 more for the rest :)

Very nice and after reading the global constraint after 40 minutes not extremely hard anymore. Thanks!

Cool puzzle! I like the idea of coloring the pad at first and then looking for the numbers!

About 40 minutes well spent. I did indeed forget about the global rule for a few of those minutes. Thanks!
