What is Casino Online?

Casino online is a website where players can play a range of casino games. These games can be played on a computer, tablet or mobile device and are available at any time of day or night.

Real money online casinos are regulated by an independent agency to ensure that they are fair and secure. This agency also audits the casinos’ slot machines and gaming tables to check that they are working correctly, and that player data is protected.

The best casino sites offer a variety of deposit options to suit different players, including Mastercard, Visa, American Express, Discover and Bitcoin. They also accept a wide range of currencies, including US Dollars, Euros, Great British Pounds and many others.

Payout percentages are an important factor to consider when choosing an online casino. These are calculated by independent auditing companies and are the expected average rate of return for a particular game at a given casino.

In addition to the payout rates, players can set their own loss limits, which restrict how much they spend in a certain time period and will stop them from spending more than they can afford. These are especially useful if you have a gambling addiction or want to avoid losing too much of your bankroll.

Bonuses and promotions are a good way to attract new customers to an online casino. They usually include a welcome bonus, which matches your initial deposit with extra cash. Other offers may include free spins on slots, which can be used to win additional cash prizes.
