▨ Foggy Loop ▧
(Published on 1. November 2023, 08:04 by ElChiglia)
---- RULES ----
Normal Sudoku rules apply: Fill the grid with digits 1 to 9 appearing once each in every row, column, and 3x3 box.
Parity Loop: Draw a single non-intersecting loop into the grid by connecting centers of orthogonally adjacent cells. The loop must fulfill the following rules:
- The loop passes through all cells containing circles while it cannot pass through those with diamonds.
- Digits in both circles and diamonds indicate how many of the up to 9 surrounding cells (including the cell itself) are visited by the loop.
- Different loop segments cannot touch, not even diagonally.
- The loop is a valid parity line. Adjacent cells along the loop have opposite parity.
Fog of War: The grid is partially covered by fog. When a correct digit is placed, the fog will be lifted from the surrounding cells.

Crazy, that it is only a ** difficulty.
But, somehow managed to solve it.
Loved it, thanks for settings, ElChiglia!
