The 2007 World Series of Poker (WSOP) kicked off on June 1, 2007 in the Rio All Suite Hotel and Casino in the capital of the poker world, Las Vegas, Nevada. For the fourth consecutive year, WSOP 2007 was run by Harrah's Entertainment which took over the event in 2004. While extremely successful, the numbers were surprisingly down in selected events due to a law against online poker.

One twist to this year's event is that all players began with a buy-in of double the chips. For example, poker players in the $10,000 no limit Texas Hold'em Main Event received twenty thousand chips, upping the excitement from previous years. Moreover, the raising of the blind structure and the withdrawal of some of the blind levels created more poker play. The Main Event brought together the game's best, starting on July 6th and coming to a conclusion on July 18th.

Adding to the inaugural $50,000 H.O.R.S.E. event of the prior year's tournament, WSOP 2007 added two more H.O.R.S.E events with buy-ins of only $2,500 and $5,000, giving more poker players the option to participate.

The WSOP winners included Tom Schneider, winner of two different events and finalist at a third, who took home the Player of the Year Award. Michael Binger and Chad Brown each had 8 money finishes as well, staking their claim as WSOP winners.

As opposed to in previous years, the yearly celebrity poker event included both high-profile celebrities and poker players. Hollywood actor Don Cheadle and well-known card shark Annie Duke hosted the event, called "Ante Up for Africa". Brandon Moran and Dan Shak battled to the end as WSOP winners and split their prize, giving the money to causes in the war-torn Darfur.

While the WSOP 2007 had a record number of players, there were actually fewer in the Main Event which is thought to be a result of a law restricting online poker and gambling. As opposed to in past years, Harrah's Entertainment prohibited online poker sites from re-selling seats to the Main Event as prizes to US players. Because the Main Event's numbers were down, the $12 million prize from 2006 actually decreased to just over $8 million in the WSOP 2007.

One unforeseen problem created a small controversy during the Main Event. Because some of the poker chips shared very similar colors, the poker players were unable at times to tell the difference between chips, both their own and others. Players had trouble assessing how much money other players had and dealers slowed down the games counting chips.

In the end, WSOP 2007 was a huge success, giving WSOP winners glory and recognition for future tournaments. With online poker becoming increasingly popular, WSOP 2008 should be even bigger.
