A casino online is a website that lets players wager real money on a variety of casino games. These sites use sophisticated security measures to protect players’ personal information, and they also employ random number generators to ensure fair play. In addition, reputable casinos have a customer support team that is available to answer questions.

Most online casinos allow players to deposit and withdraw money using a variety of methods, including PayPal. Some also offer PayNearMe, a service that allows customers to fund their account using cash at select retail locations, such as 7-Eleven, CVS, Family Dollar, Walgreens and Casey’s General Store. Some also have mobile apps that make it easier to gamble on the go.

When choosing an online casino, it’s important to find one that offers the types of games you enjoy playing. Some of the most popular games include video poker, roulette, blackjack and baccarat. Most online casinos offer multiple versions of these games, and some even have live dealer tables. Additionally, some online casinos have exclusive games that can’t be found elsewhere.

The first thing you should do before you play at an online casino is check the payout limits. This will tell you how much you can lose before the casino has to stop paying out. You can also set your own limits and stick to them, which is called responsible gambling.

Another important consideration is the number of games the online casino has to offer. Some have a huge game catalog while others have smaller selections. Those with the biggest catalogs typically have more diverse game selections, while those with smaller catalogs often focus on niche games like keno or scratch offs.
