Thermo variant #21: All Maximal Thermos are Given
(Published on 7. December 2021, 14:00 by djorr)
I've made a few thermo variants. All are standard thermo sudokus + an extra rule. Check out the others using the following link:
Thermo Variant Series puzzles
If you enjoy "Maximal Thermos", I invite you to look at the others with the same (or similar) constraint:
14. Maximal Thermos
19. Maximal Thermos 2
21. All Maximal Thermos are Given
23. Incomplete Maximal Thermos
26. Maximal Thermos 3: Stubs
31. All Maximal Thermos are Given 2
35. Maximal Thermos 4ever
Rules: Normal sudoku rules apply. Along thermometers, digits must increase from the bulb end.
Variant: The thermos in the grid are maximal thermos. This means two things:
(1) the digit in the bulb equals the length of the thermo
(2) the tip of the thermo cannot be extended by a king's move to a non-thermo cell to create a larger thermo.
For example, if r4c6 = 7 then r5c6, r5c7, r4c7, r3c5 and r3c7 cannot equal 8 or 9.
One extra rule: The non-thermo cells cannot form a maximal thermo of length 4 or larger.

Excellent puzzle! Very clever because at first, it really looked like it was going to be trivial, but after all the (relatively) obvious stuff, it had some neat logic!

Thanks Mojo872! The negative constraint is very interesting here indeed :) I'm glad you enjoyed it!

Very nice puzzle, but I think your solution code is wrong

Thank you! The solution code is not wrong, may you share yours?
I realized my solution was wrong lol. Will try again
