In the middle of the 19th century, the largest gambling destination in the United States was San Francisco. I saw it as an opportunity to create a new and interesting post on my blog. I used to link to a page about which poker games and card games were actually played in the Wild West from my links page, but the site took that content down.
Scenes like that are a staple of the genre–maybe a little bit less so in some of the more prominent spaghetti westerns, but a staple nonetheless. You’ve probably seen plenty of examples of people playing poker games and other card games in the Old West.
