Think of it like Zynga but with the chance to payout.  I tried the a free membership and I enjoyed the extra stuff videos, etc.. However,the play was horrible since it is unlimited play all-in just about every hand, the play does not improve unless you make it deep, most people are just gambling any two cards. It was good practice agianst donks, but I think I would become to frustrated if I paid for it. It has been almost a year since I tried it, I know a lot of people felt the same way I did, maybe they changed stuff to limit how many prize games you can play per month, help keep people serious. Def. worth the trial membership.
