As you would expect you can play all the main games of poker here. You'll find Texas holdem, Omaha, Omaha high-low, seven-card stud, seven-card stud high-low, Razz, and HORSE played in tournament and cash game format.
Stakes start from micro-limits of $0.02/$0.04 up to high stakes games of $100/$200. No limit tables, with games of $0.01/$0.02 blinds and $1.00 buy-ins up to $10/20 blinds, $400 buy-in games.
Sit 'n' Go tournaments run all the time and can consist of as many as 27 players at three tables, but most are either single-table tournaments with nine players or two-table tournaments with 18 players. The two-table tournaments pay out four places while the single-table tournaments pay out three places.
If you're playing on 'Stars' you must have a crack at getting into the WSOP or it's own major offline tournament – the PokerStars Caribbean Adventure which takes place in January. Satellites for these run all the time.
There is also a series of events called the World Championships of Online Poker (WCOOP) too that runs for a couple of weeks each year, usually in September. The main event of this series in 2006 was a $2,600 buy-in no limit holdem event, with a prize pool topping $6 million. The winner cashed out an incredible $670,000.
