Sub-Zero Thermometers
(Eingestellt am 20. August 2020, 22:35 Uhr von clover)
- Within a thermometer, digits strictly increase starting at the bulb.
For example, a thermometer could contain -6 -4 3 7, in that order.
A thermometer could NOT contain 3 -4 -6 7 (in that order).
- A thermometer cannot contain both a digit and its opposite (for example, a thermometer cannot contain both 3 and -3.)
- The sum of the digits along each thermometer is 0.

Lösungscode: Row 1 (digits only, ignoring any positive or negative signs.)

Very interesting! Bit of a head-twister, took me a little while to ask the right questions. Happy to see the excellent rating! :)

@SudokuExplorer That is why I wrote this comment. Perhaps you try it too?
My count is: 209 new authors and 1626 puzzles this year, definitely too much.

@Rollo That is bound to happen when on average 7 new puzzles are published per day (and 10 new ones yesterday!) when there are already more than 5000 puzzles that I haven't even looked at.
The name and number of solves of the puzzle with id=0004AJ, sums up the current situation.
The portal works best when the ratio of solvers to setters is high (or when setters solve more puzzles) so that puzzles get more feedback.

I'm not really a fan of thermometers, but this one should have more solvers. Try it!

Very nice! Took a while to figure out how to start but went pretty smoothly from there.

Normally I don't find thermometers very interesting, but this was good!

Really wonderful construction and a nice application of negative digits that does not feel artificial.

Wonderful puzzle!!!
Really well put together and the whole thing felt so original. Have really enjoyed some of your "negative" Sudokus but this is the best yet in my opinion.
[clover] I'm so glad you enjoyed it! Thanks for the feedback! :)

Are the same numbers always negative or positive? for example if i find a 6 is negative in one thermometer, does that mean 6 is negative in every thermometer it appears in?

[clover] Nope! Which is why there are so many thermometers in this one - lots of degrees of freedom to deal with.
