These sites do offer subscription VIP membership but it is not required to play their games at all
. The VIP membership does offer some better prizes and the memberships run about 20 dollars a month. These memberships also include ad free games with the exception of games sponsored by certain companies, which prizes are products of the company. Some individuals prefer to play ad free in these "Free Poker" games by purchasing the monthly membership and the games as I stated before could be higher paying games, however being "Free Poker" or "Sweepstakes Poker" like any other sweepstakes you may mail in a 3x5 index card with your information, such as screen name and address so your prizes can be mailed to you. Any and all of these sites can be found on Google; however the two main sites I choose to play are National League of Poker (NLOP) and Spade Club. I have been playing on both for years and chances are if you have played either site, then I have played against you.
