The origin of poker is uncertain. Some believe the game was originally played in Persia, while others believe it was first played in Europe during the 17th century. Regardless of the origin, poker eventually developed alongside the German card game pochen and the Spanish game primero. The game eventually found its way to the New World by way of French settlers.
Game rules for poker are a set of written procedures that all players must follow to play the game. While these rules can vary slightly from game to game, the basic premise is the same: the player with the most chips at the end of each round wins. The rules for betting intervals also differ. Generally, players must raise their bets proportionately to the number of chips they receive from previous players.
