...Digits may therefore repeat along thermometers.
Flows may merge or diverge, but must always end at a given tip.
Colours are merely aesthetic and not part of the puzzle.
Off-grid lines are not part of the puzzle.

Ditto VitP - more complex than most slow thermos, but still accessible and fun. If you're not a fan of the slow thermo genre then avoid this, but no need to force yourself to solve it and rate it badly because you didn't enjoy it.
Thank you Mr Toffee for regularly providing enjoyable slow thermos!

harder than the basic slow thermo, as indicated, in part because there are a couple branches where you can't immediately see flow direction. but standard procedures still apply - IGNORE those branches until more data is available.
the low rating is completely uncalled for. if you don't like this genre, then go away. nobody forces you to be here.
there are ZERO DEFECTS in this puzzle.
