Parity Party 2
(Published on 13. December 2025, 18:09 by galium_odoratum)
I tried to create an easy parity colouring puzzle where the disambiguation of the digits at the end does not include any arithmetics. Have fun (and do not forget about the global rule and the negative arrow constraint)!
Normal Sudoku rules apply.
Arrows: Values in cells with arrows indicate the total number of cells with the same parity in the given direction. All possible vertical and horizontal arrows are given (but NOT all diagonal ones)!
Note: Opposite parity cells do not block vision and if one cell has multiple arrows attrached to it, each arrow is counted independently!
Global parity: Each 2x2 area contains digits of both parities (odd and even).
Thermometers: Digits along a thermometer strictly increase from the bulb end.

very nice logic, but quite challenging for beginners to solve the very last bit

I forgot the global parity as well.
Very nice puzzle with or without global parity

Ah yes, the negative arrow constraint.
