Also IDK if you know but there are other games you can play and link to your account(s) (they accumulate together). I NEVER play the games that they hype or have big bells and whistles cause I feel much like IRL you pay for those bells and whistles and it never pays off. That one is different for me because it is based on the amount of chips you play and how high the LP meter goes.
In regards to Facebook, I play the Pinata one.
Also don't forget you can get free chips daily here. So again I have an android but I always bet 1% of the amount of chips I have.
