Glad I read the rules before just diving in ... thought there were Thermos involved at first glance ;-)
Even with so many given digits, this one (for me) took quite a lot of thinking and rewinding a few mistakes. It certainly looks easier than it is. Nice job!

Should I remind you that palindromes and odd circles are easily confused with thermometers...

I understand the confusion on the CTC link, but I assumed that the rules were clear. Did you have any issues in that regard?
