I've been having problems for a few days now. Don't know if it's the game or my comp. When I click a new square, a screen pops up and says I already clicked the square when I know I haven't. Also, I'll click a square and instead of seeing what was there I get taken back to the Play The Game screen. Really not sure what's happening....

Yep sounds like a bug.... if you are still having that problem try refreshing the page.. if that doesn't work then open a bug report...

Seems to be working fine today.
