I am so very grateful of all the positive comments on parity thermos and my latest puzzles with this ruleset. However, as some solvers have rightly pointed out, the wording of the rules might make them seem unnecessarily daunting and less clear overall. I have tried to rewrite them in a more straightforward manner - do let me know what you think!

Rules

Normal sudoku rules apply.

Parity Thermometers: Thermometers see only one parity. Blue ones see even digits, orange ones see odd digits.
On a thermometer, digits of the seen parity must strictly increase from the bulb end and must also be strictly dominant. Digits of the unseen parity are unaffected by the thermometer.
Bulb-to-end examples:
Valid blue thermo: 2-5-6-1-8
Valid orange thermo: 3-4-5-4-7-9
Invalid of either colour: 1-2-3-4 (no majority)

Rules (previous, yet equivalent wording)

Normal sudoku rules apply.

Parity Thermometers: Turquoise (orange) thermometers restrict only even (odd) digits. That is, on a turquoise thermometer, the even digits strictly increase from the bulb end, and likewise for odd digits on an orange thermometer. Digits of the unrestricted parity can go anywhere and in any order on a thermometer.
Thermometers are strictly dominated by digits of the restricted parity. E.g. a 6 cell orange thermometer must have at least 4 odd digits.

Might be easy to make wrong assumption in the middle but once understanding how the rule works, it was quite a smooth going for me! I don't think I have any problem with the new wording there.

This puzzle solved wonderfully smoothly, it might be one of the more approachable entries in the series but it could also just be that I'm very used to the ruleset by now. On that note I think the new wording is definitely less confusing!
