A casino online is a virtual gambling establishment, where players can play real money games like slots, roulette, blackjack and more. These sites are operated by licensed casinos and regulated by state gaming authorities. They also use encryption to protect their players’ personal and financial data. In addition, they employ staff and test the games for fairness. Some also display seals of approval from independent regulatory bodies, such as eCOGRA, which is a good sign.
