Playing cards were initially developed in the Western world soon after the invention of printing, around the 15th century. Before that, they were made by hand. The deck of cards persevered through the years, as new games and new ways to play with them evolved too. One way that adults play with cards is to gamble. Gambling is another ancient traditional form of adult play. In the 20th century, traditionally large gambling centers, such as Las Vegas, Nevada, grew even larger. More and more legal gambling centers appeared also as Native American groups sought to capitalize on their rights to build them. One of the nation's top high-quality card producers today makes the Vegas brand of playing cards. Marked "casino quality" and "the professional's choice," the cards are marketed with the extra cachet the name "Vegas" carries.
