I dived straight in, two grid locks, then realised the rule is: no two frogs the same next to each other except at ends. Did it without thinking after that.
This seems like my normal approach. I could get to the same information by thinking about it first, but playing around and seeing something in motion seems to be quicker. So I just dive in, fail a few times, then understand it.
Freude, schöner Götterfunken Tochter aus Elysium, Wir betreten feuertrunken, Himmlische, dein Heiligtum! Deine Zauber binden wieder Was die Mode streng geteilt; Alle Menschen werden Brüder, Wo dein sanfter Flügel weilt.
