Played it for a few months but this app is all setup.
What i noticed is that most players who play with all there chips on the deck somehow cant loose. You call someones bluf with good hands where only a runner runner can beat yours and somehow you get that bad beat. Thats can be bad luck if it happens once, but if it happens 3, 4, 5 or even six times to the same player on that table it isnt bad luck anymore, its a setup to make you loose. Play and youll notice. No skills needed here, only luck. I wont be suprised if zynga uses bots.
