An online casino is a digital platform where users can place wagers for real money on games like slots and table games like blackjack and roulette. A good online casino will have a wide selection of games, a secure betting system and a variety of bonuses to attract players. The best online casinos will also offer support via live chat or email.

In the past, many people accessed an online casino by downloading and installing a software program. This required a computer with a specific amount of memory and processing power. Today, most online casinos are accessed via websites that run on browsers or dedicated apps that can be downloaded onto smartphones and tablets. The apps often allow players to access the same games and features as the website, but are optimized for mobile play.

Some online casinos provide an interactive experience with real dealers for their live dealer games. These games may include roulette, baccarat and various poker variants. Some also feature prop bets, which are wagers on specific events during a game that can offer high payouts. These bets are placed alongside standard wagers on the outcome of a game, such as Over/Under bets on total points scored by both teams.

Most online casinos will require the user to supply personal information when creating an account. This includes a full name, date of birth and address. Some casinos will even ask for a credit card number. This is to ensure that a player is of legal age and can gamble responsibly. Some online casinos will even give their players the ability to set loss limits so that they do not lose too much in a single session.
