When choosing an online casino, the first thing you should check is its license. The best casinos are licensed by a recognized authority, such as the Pennsylvania Gaming Control Board or West Virginia Lottery. This ensures that the games are fair and that you won’t be scammed. In addition, they should use SSL encryption to protect your financial information. If a casino refuses to honor promotions or takes too long to pay out, contact your state’s gambling control board for help.

Besides licensing, there are a few other things you should look for in a casino online. For example, the software should be developed by a reputable developer and certified for fairness. The website should be easy to navigate and offer a wide variety of games. It should also support a range of payment methods and have an active customer support team. Finally, the site should be compatible with your operating system and have a mobile-friendly version.

In addition to these features, the online casino should have a variety of bonuses. These can include welcome bonuses, free spins, and loyalty rewards. However, you should only claim these offers if they are legitimate and the wagering requirements are reasonable.

The most popular casino games are online slots and video poker. These games feature different payout structures, including progressive jackpots. Some of these jackpots can reach millions in value. Online casinos also use random number generators to ensure that their games are fair. This prevents the house from rigging games to make money or give players false advantages.
