It suffers from the same problem as all of the other free poker games...no one takes it seriously and so the entire game falls down.
I go all in (~$5000) with a KA and a KA3 on the flop. I get a call, so I am thinking that he must have made a pair of As...turns his cards and he has.....nothing (J6 or something)...he then hit a 6 on the turn and a 6 on the river...
I am still playing it but things like that remind me why I prefer poker in the pub / casino
