A casino online is a website that allows players to play a variety of different games for real money. These sites are regulated by gambling commissions and follow the rules set out by those commissions. These rules ensure that the games are fair and that players can’t cheat or exploit loopholes. These regulations also prevent underage gambling and other problems.

Many real money casinos offer a mobile version of their site that is designed to work on most smartphones and tablets. They also have a range of games that are compatible with mobile devices, including slots and table games. Some of these websites require that you download an app, while others can be accessed on your phone’s browser.

In addition to mobile compatibility, a good casino online will offer a number of payment options. These include credit cards, e-wallets and digital currencies like Bitcoin. Some casinos also offer live chat support to answer any questions you may have. They will also offer a FAQ page to help you find the information you’re looking for.

If you’re unsure whether a real money casino online is trustworthy, check its license details. Licensed casinos should display their license number and other official details on their homepage and in their terms and conditions. You should also look at how the casino handles complaints from its customers on social media. If you see that a casino regularly ignores or dismisses complaints, it’s best to find another operator.
