I love playing these games. Everyone thinks I am an idiot at poker because I always make stupid bets and give off obvious "tells" in the first few rounds.
People are unbelievably easily manipulated. We were playing a big blind of ten cents and I managed to win twenty dollars in one night.
For me, nothing. Everything I want to do works without root. I don't tinker with my phone. It doesn't do anything cool anyway and that's what I have a PC for.
