Pointer Arrow Parity Loop
(Eingestellt am 31. Mai 2025, 01:42 Uhr von yttrio)
This puzzle using the pointer arrow loop concept used previously in Pointer Arrow Whisper Loop
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.
Loop Pointer Arrows:
-- Digits along an arrow must sum to the digit in that arrow's bulb, and all bulbs are on the loop.
-- Additionally, arrow tips point towards a cell containing the digit within the arrow's bulb, and this cell with the pointed-to digit is also on the loop.
-- The digit in the arrow tip indicates the distance from the arrow tip to the pointed-to cell. There may be other instances of the same digit between this cell and the arrow tip.
Lösungscode: Digits on the loop in row 7 (left to right) followed by digits on the loop in column 3 (top to bottom)

An yttrio loop puzzle is always lovely. This was a remarkable construction with so many interwoven parts, I can't imagine how long finding a valid grid took. For me right at the outer edge of my solving ability 4.5 stars if I could give it that, but worth every moment.

Wow! Very cool interplay of all the constraints. For me it was a clear 3* difficulty.
Thanks a lot for creating and sharing.
