The World Series of Poker Circuit is a series of poker tournaments held annually at a variety of casinos since 2005 as a build-up to the World Series of Poker (WSOP).

The World Series of Poker (WSOP) is a series of poker tournaments held annually in Paradise, Nevada and, since 2004, sponsored by Caesars Entertainment. It dates its origins to 1970, when Benny Binion invited seven of the best-known poker players to the Horseshoe Casino for a single tournament, with a set start and stop time, and a winner determined by a secret ballot of the seven players.
