Poker is a family of card games combining gambling, skill, and strategy, where players wager on the best hand according to specific rankings. Typically using a 52-card deck, players aim to win the "pot" (total bets) by having the highest-ranked hand or forcing others to fold. Common variants include Texas Hold'em. 

Poker originated in the early 19th-century United States, evolving from European and Persian card games like Poque and As-Nas. It gained popularity in New Orleans and on Mississippi riverboats around 1829–1830, initially played with a 20-card deck. The game adopted the 52-card deck, developed variations like stud and draw, and became an American cultural staple during the 19th and 20th centuries before becoming a global, televised, and online phenomenon
