Six prize winners will be randomly selected to receive a three-day/two night trip to the 2006 World Series of Poker event in Las Vegas, Nevada, where they will have the opportunity to compete in a virtual game of No-Limit Texas Hold 'Em in Activision's World Series of Poker: Tournament of Champions game on Xbox 360 for the Grand Prize -- a seat at the $10,000 Main Event.

World Series of Poker: Tournament of Champions features an immersive storyline that casts players as a newly turned poker pro building his career under the tutelage of Chris "Jesus" Ferguson, learning strategies and tips directly from one of the world's foremost poker pros. Gamers advance their career by competing against top pros in the premiere Circuit Events in hopes of qualifying for the winner-take-all, invitation-only Tournament of Champions, which is held at the Rio Resort Hotel and Casino in Las Vegas, Nevada. The game will be available this fall for the Xbox 360, as well as other platforms.

"This is the most authentic and realistic World Series of Poker video game to ever hit the shelves," said Jeffrey Pollack, commissioner of the World Series of Poker and vice present of Sports & Entertainment Marketing for Harrah's Entertainment. "Activision has again innovated for the benefit of poker players, our media partners, and, most importantly, World Series of Poker fans around the world."
