Loop the Loops by Prasanna Seshadri
or solve online (using our beta test of Penpa-Edit tools in edgex mode where left click+drag draws lines and right click marks X’s)
Theme: Quadrants
Author/Opus: This is the 14th puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Combination of Slitherlink and Masyu rules.
Specifically, draw a single closed loop by connecting neighboring dots horizontally or vertically so that each number represents the number of adjacent edges used by the loop. The loop passes through all large circles. It must go straight through the white circles with at least one side turning at the next dot; it must turn at the black circles and then go straight through the next dot in both directions.
Answer String: Enter the length in cells of each of the internal loop segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma.
Time Standards (highlight to view): Grandmaster = 1:40, Master = 2:30, Expert = 5:00

Stuck for 15 min yesterday, then gave up. Looked at today and got it quickly (somehow I thought yesterday that va gur hccre evtug pbeare, bar bs gur oynpx pvepyrf unq gb uvg gur hccre evtug juvgr pvepyr, when in fact, the opposite was true)
Yeah, I got stuck on this one for ages too, with a different mistake. Somehow it took me the longest of all six of this week’s puzzles, and looking back now I really can’t see why that was.
(I like this hybrid, btw. Always fun when givens from different familiar types have interesting new interactions.)
