World Series of Poker
The World Series of Poker (WSOP) is a series of poker tournaments held annually in Las Vegas and, since 2005, sponsored by Caesars Entertainment Corporation (known as Harrah's Entertainment until 2010). It dates its origins to 1970, when Benny Binion invited seven of the best-known poker players to the Horseshoe Casino for a single tournament, with a set start and stop time, and a winner determined by a secret ballot of the seven players.

Since 1972, the Main Event of the WSOP has been the $10,000 buy-in no-limit Texas Hold 'em (NLHE) tournament (in 1971 the buy-in was $5,000 and the inaugural 1970 event was an invitational with winner determined by a vote from the players). Winners of the event not only get the largest prize of the tournament and a gold bracelet, but additionally their picture is placed in the "Gallery of Champions" at Binion's.
