Since 1971, all WSOP events have been tournaments with cash prizes. In 1973 a five-card stud event was added. Since then, new events have been added and removed. In 2006 there were 45 events at the WSOP, covering the majority of poker variants. Currently, Texas hold ‘Em, Omaha hold ’em and Seven-card stud and their lowball variants (if any) are played. H.O.R.S.E. has been played in the past and returned in 2006. Also, S.H.O.E. has been played in the past, and returned in 2007. Other events played in the past include Chinese poker, Five card stud, and many others.

Like most tournaments, the sponsoring casino takes an entry fee (a percentage between 6% and 10%, depending on the buy-in) and distributes the rest, hence the prize money increases with more players. In the 2005 main event US$52,818,610 in prize money was distributed among 560 players, with US$7.5 million to first prize.
