An online casino is a website or mobile app that allows players to place bets and play games like slots, table games, video poker and craps over the internet. Licensed and regulated by the appropriate gaming jurisdiction, casino online sites are safe and secure. They also offer a variety of payment methods including e-wallets, credit and debit cards.

Many of the top casino online sites feature a range of sign-up bonuses to attract new customers. These can include a percentage of your first deposit or free spins on slot machines.

When selecting an online casino, make sure it is a legitimate operator with a strong brand reputation and secure software.

A good casino will display various seals of legitimacy from eCOGRA and auditing certificates from PriceWaterhouseCoopers to give players confidence that they are dealing with a trusted company.

Licensed and regulated casinos are regularly subjected to random testing by external agencies, so you can be confident that the games on offer are fair. You can also check whether an online casino is a member of an industry association or trade body, which further supports player safety.
