The word casino derives from the Italian word for little house. In the past, it was common for people to gather in public houses to play simple gambling games like dice or cards. During the 19th century, however, these gatherings became more sophisticated with the introduction of roulette and other games. The Monte Carlo Casino, which opened in 1863, was one of the first examples of a casino.
