What is an Online Casino?

An online casino is a digital platform that lets players gamble and wager real money in exchange for bonuses, loyalty rewards, and more. They often feature a variety of games including slots and table games such as blackjack and roulette. Some also offer live dealer gaming. Licensed online casinos are regulated by respected authorities and audited by third parties to ensure fairness.

Many of these online casinos allow users to play via their web browser or dedicated mobile apps. Regardless of device, they provide the same features for all users: a full range of gambling games, secure transactions and account management. A good internet connection is essential to get the most out of these platforms.

Most online casinos require players to register in order to play for real money. This process is simple and requires a few personal details like name, email address, and date of birth. Some sites also have a verification process to prevent underage gambling and ensure the security of player information.

Most real money online casinos offer a welcome bonus that matches a percentage of your first deposit with wagering credits. Some also offer free spins and other promotional offers.
