Thermo loop
(Published on 21. November 2025, 18:59 by Lutterot)
Rules
Standard sudoku rules apply.
Loop: Shade some cells such that they form a loop: a one-cell wide, closed string of orthogonally connected cells. The loop doesn't touch it itself orthogonally.
Thermometers: Digits on the straight parts of the loop are in increasing order (i.e. the straight loop sections are all thermometers).
Circles: The circles are not on the loop. Digits in circles indicate how many of their orthogonally and diagonally adjacent cells are loop cells. They also indicate the number of circles that contain that digit.
