Global Poker’s popular Rattlesnake Open online tournament series is back for a fourth time, and if the guarantees are any indication, site operators are expecting huge fields.

The 218-event series will have at least GC 675,000,000 and SC 1,350,000 up for grabs, as well as Global Poker merchandise and prizes.

The series runs from May 10-31. In fact, the site will also spread three more pop-up SC 500 freerolls throughout the series. Players can win entries into various Rattlesnake Open events, including three different buy-in versions of the main event on Sunday, May 30.

Anyone skilled enough to win an event will not only take home the top payout from the prize pool, but also a Global Poker Champion’s Pack, series trophy, and even an exclusive avatar to use on the site. Winners will also get into the Tournament of Champions, with a chance to represent Global Poker at a future live tournament.
