Walker

Big news: I am retiring from the GAPP team! I’ve been busier lately, both with work and with puzzle contests I’m writing for (like the upcoming Puzzle Ramayan Round 2). I’ll be posting two more puzzles after this one, and then staying on as the "baklog" constructor to contribute occasional puzzles when regular setters are busy. I’ve so thankful that I’ve had the opportunity to contribute to GAPP, and for everyone that’s enjoyed solving my puzzles! 🦈 (<- blahaj)

We’ve already selected the new setter who will be taking over my spot. Who could it be… 👀

Today’s puzzle is a Bhai Bahan! This genre is Prasanna's invention, and appeared in Rorschach’s River, a collaborative puzzle organized by Menderbug that jovi linked at the start of the month.

Rules: The loop visits every circle. When two circles are orthogonally adjacent, the loop goes straight in one and turns in the other.
Consider the loop split into segments, alternating between segments where the loop turns in every cell and segments where the loop goes straight in every cell. Number clues indicate the length of the current segment.

Interface Note: In the example solution, turns and straights are marked using shaded and unshaded cells: look at how the 8 clue is in a loop segment containing 8 consecutive turns. In Yajilin mode, you can mark turns and straights using shaded cells and dots.

Try the GAPP Ripple Loop, which is similar (but has a "visit all cells" constraint that this type doesn’t):
