Organisers say the 2012 World Series of Poker attracted almost 6600 entries for the marquee Main Event tournament in Las Vegas.
That means the winner of the US$10,000 buy-in No-Limit Hold'em World Championship will take home about US$8.5 million.
Tournament officials said the youngest player to enter was Cody Teska of New Carlisle, Indiana. He turned 21 on Sunday.
The oldest was 92-year-old Ellen Deeb of Troy, New York. But she was eliminated on Sunday.
The 6598 entries at the Rio All-Suite Hotel & Casino is the fifth-largest starting field in tournament history.
The Main Event prize pool is more than US$62 million. The top 666 finishers will collect prizemoney.
Play goes to July 16, when a final nine players will emerge. They'll resume play on October 28.
