What is a Casino Online?

A casino online is a virtual gambling establishment where players can access a large selection of games. These include standard casino games, such as slots, video poker and table games. They can also choose from a number of live dealer casino options. In addition, many real money casinos offer generous welcome bonuses to lure new players in. These can be worth thousands of dollars in wagering credits and may also come with free spins.

The best online casino sites feature a carousel at the top of their home page that displays the most popular games on the site. These are usually a mix of casino classics and new releases that have been well-received by players. Some of these games have a progressive jackpot, which means that the top prize could grow to be quite substantial.

In addition to the variety of casino games available, some real cash casino websites feature sports betting options. This is becoming more common as states legalize sports gambling. These games can be based on a major event, such as the Super Bowl, or on smaller details, like the amount of points scored in a game.

Most reputable online casinos feature customer support agents who are available 24/7 via email, chat and phone. Their goal is to help players with any issues or concerns they might have while playing on their site. Some of the larger operators, such as Caesars and BetMGM, also have an extensive Help Center where players can find answers to frequently asked questions.
