I have no idea, but I congratulate you, sir, on making it so far.
I definitely try to plan out moves when I’m stuck, but I find that I usually pass a level I’m stuck on when I zone out and focus on something else, just making moves kind of randomly or visually.
That’s strange, it should let you connect on fb… can you log onto FB on your phone/ipad? maybe your login credentials got mixed up on your devices?
