[1] The game is named after Wyatt Earp, a famous lawman, and is set in the American Old West.

It is manufactured by Rio Grande Games and was created by Mike Fitzgerald and Richard Borg for Alea.

Each player tries to earn reward money by participating in the capture of seven outlaws during multiple rounds of play.

It can also end when the card supply is exhausted again (i.e. a second time) after having been restocked once from the discard pile.

[1][2] Of the 78 cards in the deck, 49 are outlaw cards, seven of each of seven outlaws: Billy the Kid, Butch Cassidy, Bob Dalton, Wes Hardin, Jesse James, the Sundance Kid, and Belle Starr.

The game was first conceived as the fourth in Mike Fitzgerald's "Mystery Rummy" series, until he decided to collaborate with Richard Borg and publish it through Alea.
