Here’s a walkthrough for Freddie’s Alternation: https://youtu.be/D65pjYB4Nb8

I was counting down the hours until midnight, deciding between Nurikabe and Geradeweg for today’s GAPP. But counting cells is like counting sheep, and all too soon, I was down for the count… 😴 When I woke up, I had sleep-constructed a strange grid, with both kinds of clues (though I’ve lost count of how many of each). Well, I guess I should count my blessings; the fact that the puzzle still seems to solve has to count for something! The team’s counting on me for a puzzle, so I’ll hurry to get this Flexible Counters ready. There’s no time to waste - every moment counts!

Rules: Draw a non-intersecting loop through the centers of some cells. For a number visited by the loop, every straight line segment that touches the number must have a length equal to the number’s value. For a number not on the loop, the number represents the number of cells in its orthogonally connected area of cells not visited by the loop.

In this puzzle, clues visited by the loop behave like Geradeweg clues, while clues not visited behave like Nurikabe-Like Loop clues (though you can have multiple or none in a region). If you’re unfamiliar, you may want to try the first GAPPs for these genres:
