This is a Monday nurikabe puzzle, in addition the edges fold around (So R1C5 touches R10C5)
So apparently I failed at skyscrapers week. Skyscrapers always manage to trip me up one way or another, I always just skip over them if I can on an LMI test. I am fascinated by skycraper sequences though. I found this paper by this wonderful mathematician/puzzler/blogger if you haven’t already heard of her.
