A casino online is a gambling website that allows players to place wagers using real money. The games can be played on computers, tablets, or mobile devices. The website must be licensed by the state and follow strict security protocols to protect player information. It must also have a customer support team to answer questions. Players can contact customer service through live chat or email. Depending on the type of game, the casino may also offer tournaments and progressive jackpots.

Among the most important factors in choosing an online casino is whether or not it offers a variety of banking options.
