PokerStars.com has reached a very impressive milestone, announcing that for the first time the site had 100,000 players playing simultaneously last week, and to mark this impressive achievement they are guaranteeing $1 million in prize money for each of their regular weekly tournaments.

Beginning February 27th, all Sunday afternoon no-limit hold'em tournaments - with buys-ins of either $215 or $530 - will pay out at least $1,000,000 in prize money to the top finishers. On the final Sunday of every month, the buy-in is $530. For all other weeks, it's $215. PokerStars also offers a quarterly tournament with a $1050 buy-in.
