World Series of Poker (WSOP)

The World Series of Poker, also known as WSOP, is a set of poker tournaments that happens to be the largest in the world. This is held in Las Vegas every year, and since 2007 it has involved 55 events. Except for the main event, these events last for more than a month. The major variants of poker are featured in the WSOP, although more than half of the events in recent years have been variants of Texas hold'em. The culmination of the series is the $10,000 no-limit hold'em main event. Since winners of this event are granted multi-million dollar prizes, thousands of hopefuls every year take their chances by participating. Each winner of an event is awarded with a cash prize and a World Series of Poker bracelet.

Sponsored by Tom Moore, the World Series of Poker began as an invitational event held at the Holiday Hotel and Casino in Reno during 1968. However, the set of tournaments that would later become the World Series of Poker is actually the brainchild of Benny Binion, a Las Vegas poker player and casino owner.
