    Hold'em Poker+ is one of the most widely played mobile skill-based strategy poker games in the world. In this unique twist to traditional Texas Hold'em Poker, three community cards are first dealt followed by four rounds in which the players pick their cards based on desired face value. Played against virtual opponents, the object of the game is to skillfully put together a winning hand without being blocked, while trying to block a virtual opponent that might be building a better hand.
    "Hold'em Poker+ for Prizes is an exciting twist for America's most popular game, Texas Hold 'em," said Robert Williamson III. "I am proud to launch the Mobile Mega Tournament Championship and I look forward to playing with fans on my cell phone."
    The simple gameplay lends itself well to the mobile screen, allowing poker experts and novices alike to compete in head-to-head and weekly high-score tournaments. After three months of skill-based competition in the Hold'em Poker+ For Prizes Mobile Mega Tournament, the Grand Champion will emerge. Sony PSPs will be awarded to the Best Score Champion, the Best Average Score Champion, and the Best Ranking in Head-to-Head Champion.
