This is the third puzzle in a loop series that uses thermometer clues. Links to the previous puzzles in the series is given below.
Heated Whisper Loop
Heated Dutch Loop
Rules:
Normal Sudoku rules apply: Place the digits 1 to 9 in every row, column, and 3x3 box.
Along thermometers, digits must strictly increase from the bulb to the tip.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
-- All thermometer bulbs must be on the loop.
-- The digit in a thermometer bulb gives the total number of loop cells in the 3x3 Sudoku box containing the bulb.
-- The loop acts as an entropic line. Each set of three adjacent digits along the loop must be one low [123], one medium [456], and one high digit [789].
Solution code: Row 4

This is a tough cookie but it's very sweet and rewarding. Imagine eating a Reese's cup with a pretzel inside it that was left in the freezer for a few days.

Very nice puzzle! I managed to screw that up badly last night and decided to completely restart today. I'm glad I did because it was really pretty and smooth as butter the second time.

Wonderfully tricky! Also 4 stars for me, but it flows beautifully, so I would have finished quite quickly if I didn’t overlook a clue for so long…

This is amazing! Quite hard though. I feel like it's a 4* puzzle.
