The background to the first "real casinos" is comprised of a significantly shorter story. These were due to occur in North America in the early 20th century, and the predecessor to the more organized form of gambling was something that was often portrayed in "Western movies"; i.e. "Saloons". When towns grew up as new builders and emigrants spread across North America at the end of the 1800s, the Saloons became the natural places along the stretches where strangers could stay, exchange news and events from different parts of the world and, above all, play some cards before moving on on his journey.
Many have certainly had Salooner portrayed on film as infamous courts with jokes, bandits and prostitution, where games were played and drank, of which a game could quickly develop into a fight or a gun duel of life and death. In many cases, it actually looked like this before the legal system was eventually reformed in the US in the early 20th century.
The salons - how everything started
However, there was a short backlink to developments as gambling was soon banned in most US states in the early 20th century, as a result of the rapid reformal and social winds swept through the United States at the time. The first state, however, came to lift the ban was Nevada, of which its today-known city of Las Vegas came to get North America's first "real" casinos. In Nevada, you quickly realized the money that could be earned by investing in a large scale on the game model in which you played against the house, while maintaining a slight advantage over the player.
After just a couple of decades later, a host of large casinos had opened in Nevada (which until 1978 was the only state that allowed gambling in the United States). Las Vegas was the biggest center of gaming, and it did not take long until its well-known position as the casino world's mecca was born. In 1978, then New Jersey became the second state to lift the game ban, of which Atlantic City became North America's second largest "casino city". It was just in Atlantic City that the cards of the cards were in the game Blackjack to start.
