PokerStars is the largest poker site in the world, offering massive volume in cash games and tournaments on a 24 hours a day basis. It sets the standard in the industry for tournaments as well.  It has an unmatched selection and sit-and-gos at all stakes starting up virtually every second.

The software is also great and offers fast play, high reliability, great multi-table options and a lots of customization – it pretty much sets the bar for the industry there.

If you’re looking for a disadvantage, it’s probably the inconsistent competition. Because of the huge player base there are some very fierce opponents on the site if you select the wrong game.

If you like more obscure poker variations, PokerStars is for you with a wide variety of games offered – Texas Hold’em, Omaha and Seven-Card Stud in all versions, H.O.R.S.E., H.O.S.E., 2-7 Triple Draw, Five-Card Draw, Razz, 2-7 Single Draw Lowball, Badugi, 8-Game, Mixed Hold’em and Mixed Omaha Hi/Lo. By the time you read this, they’ve probably added more.

PokerStars also has a great loyalty program and becoming a Supernova player is a status that is coveted throughout the online poker community.

The bottom line is that PokerStars is one of the best poker sites in the world and if the competition wasn’t so tough at the higher stakes, it would be tough not to rank PokerStars higher.

Real-money player statistics as of January 2011 show 22500 ring-game players at peak hours and 55000 tournament players at peak hours.
