# Offline poker Poker is a game that has been played for centuries, with its origins shrouded in mystery. Some believe it originated in China, while others believe it was first played in Persia. Regardless of its origin, poker has become one of the most popular card games in the world. In the mid-1800s, the 52-card deck used today was introduced, and with it came new game variations. One of the most popular variations was a five-card draw, which is still played today. Poker took off in the United States during the Wild West era. Saloons and gambling halls were filled with cowboys and gamblers looking to make a quick buck. Poker became a staple of these establishments, with famous players like Wild Bill Hickok and Doc Holliday making a name for themselves at the tables. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
