Does it cheat?

Yeah, it cheats. Plain and simple. No human player could ever match its probability of really great rolls, or its conspicuous ability to deny you re-entry in a simple three point board when either of you have blots lying around. Its good practice, though. Just dont let it get you steamed. I like the Tutor feature, but oftentimes when I take its advice Im sorry!
I give it two Stars, but would rate it much higher and play it much more if it didnt CHEAT! Ha ha!
Happy, or Disappointed you ask?
Disappointed.
