I finished Episode 10 of Artifact Seekers with 8 stars. I had only 7 but went back in and replayed one puzzle that gave me a star for being quick. I did, however, consult that guide a couple of times in this episode. My brain isn't working as well as it was when I first started playing the game. I'm not understanding some of the puzzles.
I have also been playing Escape Rosecliff Island (hog) and replaying The Spell (match 3).
