7 Loop
(Published on 2. May 2022, 17:34 by Innocuous)
Rules:
Normal Sudoku rules apply. In cages, digits sum to the small clue in the corner.
Draw a single closed loop that moves orthogonally through the grid and passes through the 8 outer boxes. The loop may not cross itself or touch itself orthogonally. All cells on the loop are grouped in adjacent pairs; digits in each pair sum to 7.

beautiful interplay of logic between the 7-sum line, the cages, and plain old sudoku! that tricky deduction halfway through is devilish, got me stuck for a long while.
