Acquisition by Harrahs

In 2004, Harrah's Entertainment (now Caesars Entertainment) purchased Binion's Horseshoe, retained the rights to the Horseshoe and World Series of Poker brands, sold the hotel and casino to MTR Gaming Group, and announced that the 2005 Series events would be held at the Harrah's-owned Rio Hotel and Casino, located just off the Las Vegas Strip. The final two days of the main event in 2005 were held downtown at what is now the MTR-operated "Binion's" in celebration of the centennial of the founding of Las Vegas. It also added a made-for-television $2 million "freeroll" invitational Tournament of Champions (TOC) event first won by Annie Duke as a "winner-take-all" event. A Binion's poker table signed by WSOP Champions and other professional players after the casino hosted its final WSOP. Starting in 2005, the WSOP began a tournament "circuit" at Harrah's-owned properties in the United States where, in addition to the $10,000 buy-in tournament at each site, qualifying players became eligible for a revamped Tournament of Champions. The 2005 TOC, made up of the top twenty qualifying players at each circuit event, along with the final table from the 2005 Main Event and the winners of nine or more bracelets (Johnny Chan, Doyle Brunson, and Phil Hellmuth) would participate in the revamped TOC at Caesars Palace. Mike Matusow won the first prize of $1 million (US), and all the players at the final table were guaranteed a minimum of $25,000 for the eighth and ninth place finishers. During a break in the final table of t

e 2005 Main Event on July 16, Harrah's announced that eleven properties including the recently added Bally's and Caesar's properties would host 200506 WSOP Circuit events that started on August 11 in Tunica, Mississippi. One event that was scheduled for Biloxi, Mississippi, was canceled after the Grand Casino Biloxi, which was scheduled to host the event, suffered major damage from Hurricane Katrina. The Rio also hosted the 2006 World Series of Poker, which began on June 25 with satellite events and formally began the day after with the annual Casino Employee event, won in 2006 by Chris Gros. 2006 featured the Tournament of Champions on June 25 and 26, won by Mike Sexton.
