Normal Samurai Sudoku


Slow-Thermo

(O) Bulbs ≤ Tips ( I )

Digits mustn't decrease along thermometers from bulb to tip.

Finding the flow is part of the puzzle.


Try the puzzle here

It has a 4 where a 3 should be in Box 9 of Grid 2 in the solution checker, sorry.

For another, very slightly different, revamped, slightly harder and possibly more interesting to solve version that has (hopefully) correct solution checking try the new version here

the solution code is the same. I would like to thank "hige" for helping refine this puzzle.

Solution code: First three digits from R1, the last three digits from R1, then the first and last three digits from R21. (12 digits in total)

Changed solution code to hopefully the correct set of digits, I was one number out. Methinks another go at a solution coded puzzle is in order, copying and testing this puzzle has been a nightmare! Apologies BButrosGhali. Thanks for making the effort.

I cannot find any sudoku errors or slow thermo violations in my solve (113 min), but my solution code is wrong (and the CTC page thinks it's wrong as well, but I'm not sure if it can handle samurai checking). Is any help available?

EDIT: Thanks for the quick update! The new code matches mine.

Not going to lie, that's how long it took me to check it!!! Thank you for taking the time to comment after that ordeal! Glad you enjoyed it.

Took me a whopping 4 hours to solve. Thermo logic is hard for me, but I had fun the entire time. Very lovely puzzle, thank you for sharing :)

After 2 hours of solving and a little bit of back and forth with the setter, I feel so stupid for misreading the solution code description m(
