10s And Thermos In The Fog
(Published on 15. December 2025, 21:34 by krujedioses)
10s And Thermos In The Fog
Rules:
- Normal sudoku rules apply: Place the digits 1 to 9 in every row, column, and 3×3 box without repetition.
- Kropki Dots: A white dot between two cells indicates that the digits are consecutive. Not all possible dots are necessarily given.
- Killer Sudoku Cages: The digits within a cage (outlined region) must sum to the number indicated in its upper-left corner (the leftmost cell of the topmost row of the cage). Digits cannot repeat within a cage.
- Thermometers: Digits along a thermometer must increase strictly from the bulb to the tip. Each thermo has its own colour and they do not branch or overlap.
- Dynamic Fog: Portions of the grid are initially covered by fog. As digits are correctly placed, the fog dynamically clears, revealing more of the puzzle.

The resolution of the final thermo was *chefs kiss*. Really loved it, deserves a higher rating,

Solved in 37:55, this was very nice!

Fun puzzle, thank you for setting this! I also think that this should be higher rated, I get that the colour choices were a bit debatable in the earlier version, but overall it is a nice construction :)

Again, changed the colour of the thermos for better viewing. Thanks for the feedback!

I solved it so it can't be more than a three. but it took me an hour so lets say 2.75*. ;)

Very nice but probably more of a three star puzzle I feel.
The thermo in box 1 has a colour that makes cell marking hard to read.

Changed some thermos colours to improve visibility.

I really enjoyed this one. Thank you.

thanks to sparky, and building on what senny said:
the box 1 thermo is much too dark, and there's no reason for it. that's survivable.
more importantly, the yellow thermo IS FULLY INVISIBLE, unless you position your head very specifically AND use a microscope. this has nothing to do with the puzzle, and is based on properties of the monitor. and that is unacceptable.
both of these problems could be solved, trivially, by simply exchanging the colours of those 2 thermos.

Nice fog, not too easy!
For VitP : You need to use pencil marking and clues that are slightly, but purposfully visible ! I hope this helps

and how, exactly, does this resolve, after box 1 is cleared out, with a million candidates and no clues ?

If I may suggest something, try not to use so vibrant colors. It was not pleasant for eyes and also digits on blue thermo were not visible at all.
As for the puzzle, it was very well constructed and I had a lot of fun solving it! :-)
