A casino (also spelled casin) is a gambling establishment. In the United States, casinos are most often built near or combined with hotels, resorts, restaurants, retail shops, and other tourist attractions. Some casinos feature entertainment venues such as stage shows, comedy clubs, and sports arenas. Most casinos also offer various games of chance, such as slot machines and table games like poker, roulette, and blackjack. The term casino may also refer to a specific game of chance, such as bingo or keno.

Because large amounts of money are handled within a casino, it can be tempting for patrons and staff to cheat or steal, either in collusion or independently. For this reason, many casinos have security measures in place to deter such activity. Security cameras are common in casinos, and employees are trained to recognize potential problems.

Many casinos are designed with impressive architecture and decor, making them a tourist attraction in their own right. One of the most famous is the Venetian Macao in China, a gleaming edifice that lives up to its name and evokes the grandeur of the original Monte Carlo casino. It has also been featured in several James Bond novels and films.

Most online casinos offer a variety of real money gaming options, from slots to table games. The majority of these casinos are regulated by government authorities to ensure fair play and player protection. Many of these sites also offer a range of different payment methods, including e-Wallets, debit cards and direct bank transfers.
