A casino is a gambling establishment where patrons may play various games of chance for real money. The most common games are blackjack and roulette, but there are many others. Most casinos also offer a variety of dining options. Some are world renowned, such as the Casino de Monte Carlo in Monaco. Other casinos are simply spectacular, such as the MGM Grand on the Las Vegas strip or the Marina Bay Sands in Singapore.

In general, a casino has a long-term advantage over the players, known as the house edge (or vigorish). However, some games have a skill element, and players possessing sufficient skills can eliminate this disadvantage, earning them a short-term profit. These players are known as advantage players.

It is important to note that, irrespective of the game chosen, a casino must provide its patrons with security measures. This includes preventing them from cheating or stealing, either in collusion with other patrons or on their own. These measures may include surveillance cameras, but are most often comprised of human security personnel patrolling the gaming areas.

The majority of online casinos require verification of your identity before you can withdraw funds. This process, which is sometimes referred to as KYC (Know Your Customer), involves confirming your identity by providing the casino with a copy of your government issued ID or other documents as requested by the casino. The procedure is typically initiated by the casino when you request your first withdrawal.
