Poker

Poker is a card game of chance and skill and is native to Earth. The main aim of the game is for players wager on the strength of their cards, in relation to the cards held by the other players. If a player believes they hold a greater "hand" than another player, they can "call" them on it.

During the USS Enterprise's encounter with the Fesarius in 2266, the Enterprise was threatened with destruction. Lt. Commander Spock suggested to Captain James T. Kirk that they had been "checkmated", Kirk took the gaming analogy to find a "bluff" from poker that they could use against the Fesarius. Spock was fascinated by the game of poker and Dr. Leonard H. McCoy vowed to teach it to him. (TOS episode: "The Corbomite Maneuver").

During the 2360s, the command staff of the USS Enterprise-D played a poker game every Tuesday night. (Star Trek: The Next Generation).
