U.S.-facing online poker site Global Poker saw its Rattlesnake Open kick off just over a week ago, and the response has been much better than expected. If things continue at the current pace, the 135-event series will end up paying out double the advertised guarantee of $1.25 million.

A $5,000 freeroll got things started last Sunday, and saw 3,132 players take to the virtual felt. All events across the first four days exceeded their guarantees—some by a little, others by more than double. The $110 6-Max tournament on Monday night had a $10,000 guarantee, but by the time it was all set up, the guarantee had been pushed to over $22,000.

The series offers tournaments for any budget and any taste—No-Limit Hold’Em (NLHE), Pot-Limit Omaha and Fixed-Limit Hold’em. Buy-ins range from $3.30 up to $218 and there will be three NLHE Main Event tournaments on May 20, starting with a $22 buy-in $15,000-guarantee tournament. There will also be a $110 buy-in tournament with a $40,000 guarantee and a $218 tourney with a guaranteed prize pool of $100,000. Several satellite tournaments are being offered for as low as $0.55 to try for a place in the $100,000 Main Event.

In addition to the cash prizes, winners also receive a Rattlesnake trophy and a Global Poker Champions pack. The pack can typically include GP-branded items such as t-shirts and baseball caps.
