How many records were broken at the World Series of Poker Colossus in Las Vegas?

Here’s how to make a 1,130 times return on your investment: Enter the World Series of Poker Colossus event, where an initial $565 investment can turn into $638,880. Well, at least for the winner.

The event at the Rio Las Vegas Hotel and Casino opened the 68-event poker tournament with 22,374 official entrants. In the history of live poker, it’s the highest number of players ever to take part in one tournament.

Previously, that record was held by the 2006 Main Event which drew 8,773 players. The Colossus blows away that event by 255%.

The high number of entrants means a total prize pool of $11,187,000, and a record 2,241 players will receive a minimum $1,096 for 2,241st place or higher.

The event also compares in crowd size to the Floyd Mayweather-Manny Pacquiao bout that drew a sold-out crowd of 16,800 in May, the NBA’s record-breaking season average attendance of 17,826 or the National Hockey League’s average attendance of 17,443.
