Loopy Parity X-Sums
(Eingestellt am 20. Juli 2024, 02:56 Uhr von yttrio)
Rules:
Normal Sudoku rules apply.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
The loop acts as a parity line: digits along the loop must alternate between even and odd digits.
Clues outside the grid are loop-cell X-sums. They indicate the sum of the first X digits on the loop in the row or column, where X is the digit next to the clue (and not necessarily on the loop). X cannot be larger than the number of loop cells in the row/column.
Lösungscode: Cells on the loop in row 9 (left to right) followed by cells on the loop in column 8 (top to bottom)

Great puzzle! It took me a while to solve, though. Not a 3-star for me (more like a 4).

Tough but adorable puzzle. The loop variant of the X sums together with the parity is used so clever. What a mind bending experience. Thank for sharing.
