|The casino comes from the Latin “casa,” which means house. Casinos were built in Italy as big houses with many rooms where people could gamble. The first online casinos appeared in 1994 after the liberalization of gaming laws for online gambling in Nevada (the only state where it was legal). Since then, online casinos have become an amazing business for companies around the world. They host hundreds of thousands of players who want to play online casino games at any time they choose to without having to leave their own home or hotel room.
