The 2012 World Series of Poker was the 43rd annual World Series of Poker (WSOP). It was held at the Rio All Suite Hotel and Casino in Paradise, Nevada between May 27-July 16, 2012, with the final table of the Main Event delayed until late October.
There were 61 bracelet events, culminating in the $10,000 No Limit Hold'em Main Event beginning on July 7. From 2008 through 2011, Main Event final tables were delayed until November. However, due to the 2012 U.S. presidential election, this year's final table was delayed until October 29, with heads-up play commencing the following day.
New tournament formats introduced in the 2012 WSOP included a re-entry tournament, an ante only tournament, a mixed max tournament (in which the number of players per table changes at set times during the tournament), and a four-handed tournament.
The 2012 WSOP also hosted an event with the largest buy-in in poker history, a $1 million tournament benefiting the One Drop Foundation. The WSOP waived its normal 10% rake of the entry fees, and 11.1% of each buy-in (precisely $111,111) went to the foundation. All 48 seats available for the event were filled, resulting in a first prize of $18.3 million, breaking the record of $12 million won by Jamie Gold at the 2006 WSOP. One Drop initially received US$5.44 million, including a 49th/personal $111,111 donation from Caesars Interactive Entertainment CEO Mitch Garber, who was ineligible to play because of his role with the company.Guy Laliberté, the founder of the One Drop Foundation, finished in fifth place; he donated his entire winnings of US$1,834,666 to the foundation, for a total donation of US$7.28 million from this single tournament game.
The $10,000 No Limit Hold'em Main Event began on July 7. In a change from previous years, which featured four starting days, there were only three starting days at this year's event. The players from days 1A and 1B then played on days 2A and 2B, which were held the same day in separate rooms, while the players from Day 1C played on Day 2C. After reaching the final table of nine players on July 16, the remainder of the tournament was delayed until October 29.
