Paired Parity
(Published on 28. March 2025, 02:13 by Paper Boat)
Normal sudoku rules apply. Place the digits 1 through 9 in each row, column, and 3x3 box.
Slow Thermos: On thermometers starting from the bulb, digits must either increase or remain the same (if allowed by other rules).
Parity Thermos: The digits along each thermometer will all either be odd or even. (e.g. from the set of digits 1,3,5,7,9 or from the set of digits 2,4,6,8)
This is my second set now, thanks to all of the encouragement I received for Peach Ring! If you have any suggestions for improvements to the puzzle I would love to hear them, thanks for playing my puzzle. :)
Solution code: Enter the digits in row 9 in order with no spaces.

Supreme logical clarity. Excellent setting. Might be too easy for the experienced solvers.
