National Poker Day is widely attributed to Rick McNeely, a Texas radio personality known as DJ Rick, who is credited with establishing the observance in 2019. No primary documentation from the founder has been identified to confirm this attribution.
Poker spreads through war and westward expansion
The Civil War accelerated poker's spread as soldiers from both sides played variations including stud and draw poker to pass time between battles. By the end of the 19th century, the game had migrated from the river to saloons across the American West. The introduction of the Joker as a wild card in 1875 added new dimensions, and lowball and split-pot variants appeared around 1900.
Texas Hold'em, the variant that would eventually dominate competitive play, originated in Robstown, Texas, in the early 1900s. It remained a regional curiosity for decades until Corky McCorquodale introduced it to Las Vegas in 1963 at the California Club. Texan gamblers Crandell Addington, Doyle Brunson, and Amarillo Slim promoted the game aggressively, with Addington describing it as a "thinking man's game" that emphasized strategy over luck.
