The Heat Between Us
(Published on 20. January 2025, 23:50 by marty_sears)
- Normal sudoku rules apply.
- Entering correct digits may clear fog somewhere in the grid. No guessing is necessary.
- In this puzzle, coloured lines are 'edge thermos'... these run along cell edges.
- Any cell edge covered by a thermo contains a thermo spot. The value of a thermo spot equals the sum of the digits in the two cells it sits between. Values of spots along a thermo strictly increase moving away from the bulb (the large spot at one end.) Each thermo is a different colour, and they don't overlap or intersect each other.

Solution code: Row 9 from left to right

I think having the rules specify that each colour thermo only appears once would be helpful. As stated, there's no logically backed reason to assume the two red thermo parts are the same thermo.
Marty: It says every thermo is a different colour, so there can't be two red thermos
DiMono: Ah, I missed that. Never mind then. :D

Very nice ruleset and a lovely break-in. Thanks

As usual with Marty puzzles it felt about one star harder than the rating - not a bad thing though! Very very clever and nice to solve, I hope the ruleset sees more love

Very fun and interesting thermo variant - really enjoyed it. Thanks for the lovely puzzle!

Took me quite a while to solve, but enjoyed the interwoven defuctions a lot.
Also looking forward to (hopefully) re-experience this ruleset for the Finks-Twins?!? <3

Definitely on the easy side of 2* - it was a bit of trouble getting used to the new edge thermos, but once it all came together, it was a breeze to solve!

Lovely idea. My first thought was 'why the two blank cells at the bottom?' and I got the logic immediately. Really neat use of dynamic fog.

Very nice puzzle, felt like it was meticulously crafted!

Truly exceptional!

Very fun and a variant of thermo I haven’t seen before. I found myself channeling my inner Simon at one point as I said out loud “Do I actually have to do sudoku now?”

Lovely. The pacing was delightful. Each reveal felt like an achievement. Great ruleset. Thanks for sharing.

Amazing how you come up with yet another original idea, and very well executed.

Near the end I made a wrong assumption and had to unwind that logic, but going back through it's just so clear the beauty of this design! Wonderful work as always.

A very interesting new rule set, but very well constructed even if entering a lot of digits failed to reveal any fog which was a little disconcerting.

Excellent! I enjoyed the new constraint, it was a lot of fun. :)

It took me a while to get my head around it, but after some time they started making sense. Loved it

Another fresh idea executed with elegance, approachability, and lots of fun. Signature marty. Thanks!

Great break-in!

Interesting new constraint! Especially the breakin was very cool

Perfect introduction of this new constraint. I‘d like to see more puzzles using it. Thank you very much for creating and sharing this lovely idea.

Wonderful new concept for me, helped along by the fog forcing me to think in the right way

What an interesting idea for constraint! Fun and novel puzzle.

Beautiful! Great idea for a ruleset.

Very nice take on thermo logic. Thank you for this fun puzzle, Marty!

Seems difficult at first but solves very nicely. Thank you!

Lovely. Really fun twist on thermos. Almost literally a twist.
