Slow Thermal Arrows
(Published on 15. June 2021, 09:53 by EliasKar)
Also, each arrow path acts a slow thermo, whose bulb must be discovered. This means that the digits on each arrow path must increase or remain the same, when read from one of the two possible directions. If read from the other direction, they must decrease or remain the same.
Note: Two-cell arrows always obey this rule, no thermo logic can be used on them in this puzzle.
You can find valid (green) and invalid (red) examples in this link.

Solution code: Row 6 and Column 2 (18 digits, no spaces/commas)

Some nice logic around the thermo arrows, but still quite challenging afterwards. *Phew!* Thank you!

OK，I know，Thermometers are not strictly increasing, they may pause, such as: 9-1-1-7, thank you for your reply!

@cdwg2000 those are slow thermos, they can increase or remain the same. The arrow starting at r9c3 is therefore possible by repeating a number without 2/3 in the middle I guess :)

Can you clarify the rules: a 3-cell thermal thermometer can fill in 126/135/234/125/134/124/123, and the second box in the arrow direction of the arrow Sudoku can only fill in {2/3}, and then the fourth column is contradictory Again, where did I understand it wrong? Thank you!
@Lakritze explained it great in another comment, check it out! Αlso, take a look at the example link, it might help!
