Online casinos offer a variety of casino games over the internet. They can be found in various countries around the world and include slot machines, table games, and video poker. Some also offer live dealer casino gaming. Online casinos typically accept credit card payments and use payment processing software to ensure that players are paid their winnings. The biggest online casinos have annual revenues of billions of dollars.

The process of launching an online casino starts with finding game developers to partner with. You can do this either by contacting the game developers directly or buying a bundle of games from a B2B provider. Once you’ve partnered with game developers, you’ll need to set up payment systems and start promoting your online casino. Choosing the right payment processor is also critical, as you’ll want to be able to accept all major credit cards and cryptocurrencies.

A typical online casino will welcome new customers with a promotional welcome bonus. These typically entitle new players to a percentage of their initial deposit in bonus credits, up to a certain limit. Most will also add extras like free spins to this welcome offer.

Online casinos that are real money can be found in a number of different states, including Connecticut, Massachusetts, Michigan, West Virginia, and Pennsylvania. To play in these casinos, you’ll need to create an account and provide proof of age. Some online casinos will allow you to verify your identity using a document like a driver’s license or passport.
