An online casino is a gaming platform that offers slots, table games, video poker and more to players over the Internet. It attempts to replicate the ambiance of traditional brick-and-mortar casinos, and it entices and retains players with bonuses, promotions, and other rewards. The most popular online casinos offer hundreds and even thousands of different games, including some that are rarely found in physical gambling establishments.
Unlike physical casinos, online casinos do not shoulder the same costs, so they can afford to give their players generous rewards. This can be in the form of huge welcome bonuses or hundreds of free spins. Some sites also give a percentage of your losses back, making it easier to get your bankroll back on track.
Other rewards include loyalty bonuses, which reward regular spending with extra credit and other perks. These are typically based on how much money you have spent in the casino, and they can range from cash, to bonus tournament tickets and merchandise.
Another important criterion for choosing an online casino is the availability of a wide variety of deposit and withdrawal methods. This includes both traditional payment systems such as Mastercard and Visa, and e-wallets like Skrill and Neteller. In addition, some sites accept cryptocurrencies such as Bitcoin.
A good online casino should also have a mobile app and an in-browser version of its website. Both of these options allow players to access the site from any computer or device with an Internet connection.
