Online casinos are websites that allow players to wager on casino games. They can be played using a desktop computer or mobile device. The casino games may include slots, poker, roulette, blackjack and other popular choices. The games are configured to give the casino an edge, which means that over time, they will make money. The house edge is the result of math and algorithms. This is different from traditional casino play because the outcomes are not random. Players have no control over the outcome of a game, but they can choose which games to play.

The best regulated casinos offer multiple payment methods for depositing and withdrawing funds. Most accept credit and debit cards, with some allowing players to use an eWallet such as PayPal to transfer money quickly and securely. These popular wallets can be linked to a casino account so that money is instantly transferred between the two. Many players like to use these options as they provide an extra layer of security and speed when playing online.

A top online casino should also offer loyalty bonuses to their existing players. These rewards can range from cash and bonus credits to merchandise and free tournament tickets. In order to receive these bonuses, players must be active and deposit a minimum amount within a certain period of time.

In addition to the casino games themselves, a top online casino should display various seals of legitimacy from reputable regulators as well as audited payout certifications. These are signs that the casino is following best practices and trying to keep its players safe.
