An online casino is a gambling website where players can wager and win real money. These sites are available on computers, tablets and smartphones, and provide a variety of games. Some even offer live dealer action, bringing a more authentic experience to the table. The online casino industry is booming and continues to grow as technology advances.

Online casinos need to be licensed by a recognized regulator in order to operate legally. This is to ensure that the gambling software used on the site is fair and that winnings are paid out promptly. Players should always read the license details and verification methods before depositing any money at an online casino.

It is also important to check whether the online casino accepts your preferred payment method. There is nothing more frustrating than playing at an online casino that does not support your preferred banking option. Besides credit/debit cards, eWallets and cryptocurrencies, many online casinos also offer other methods like bank wire transfer and prepaid cards.

A good online casino should have a responsive customer support department to answer any queries you may have. Whether you need assistance with your account, game play or simply have a question about the site, you can contact the support team through email, telephone or live chat.

Another thing to look for is whether the online casino has a mobile-optimized version of its site. The best ones will allow players to access their favorite games through their web browsers or dedicated apps available on iOS and Android devices.
