How to play Omaha Poker
Gambling dates back to the Paleolithic period, before written history. In Mesopotamia the earliest six-sided dice date to about 3000 BC.
However, they were based on astragali dating back thousands of years earlier.
In China, gambling houses were widespread in the first millennium BC, and betting on fighting animals was common. Lotto games and dominoes (precursors of Pai Gow) appeared in China as early as the 10th century.
Playing cards appeared in the ninth century in China. Records trace gambling in Japan back at least as far as the 14th century.
Poker, the most popular U.S. card game associated with gambling, derives from the Persian game As-Nas, dating back to the 17th century.
The first known casino, the Ridotto, started operating in 1638 in Venice, Italy.
