①❷③ Modular-Sequence-Loop ④❺⑥

---- RULES ----
Normal Sudoku rules apply: Fill the grid with digits 1 to 9 appearing once each in every row, column, and 3x3 box.
Modular Loop: Draw a single 1-cell-wide loop of orthogonally connected cells into the grid. Different loop segments cannot touch, not even diagonally. The loop acts as a Modular Line. Any group of three consecutive cells along the loop must contain one each from the sets [147], [258], and [369].
Circles: Cells containing a circle must be on the loop. Every cell with a circle must be filled with a different number (i.e., they form a complete set of the digits 1 to 9) and the loop must visit the circles in the order of their numbers (...89)123456789(12...).
Thermometer: Digits along a thermometer must increase from bulb to tip.

This felt quite hard and then it was suddenly finished. Very interesting and different loop logic. Wonderful idea!

One of my favorites in the series so far!

This one had some really fun (and pretty unique) loop-building logic, and it's quite incredible how much disambiguation work the thermo was able to do!
