Here is a game with most of the numbers filled in.
It shows the possibilities remaining for each open square. I don’t see any obvious moves left. I want to finish it without guessing….. At this point, it looks to me like the only way to finish this one is to run through various scenarios in my head or on paper. My head isn’t big enough to hold very many consecutive imaginary moves, so that means I write it all out on paper or I guess. (I don’t really write it out on paper.) Most of the open squares have only two possibilities each. Only three squares have three possibilities each. Is there something to make of that?
