A casino (or kasino) is an establishment that offers various forms of gambling. Casinos are most often built near or combined with hotels, restaurants, cruise ships, and other tourist attractions. They may also be known for hosting live entertainment events such as stand-up comedy, concerts, and sports. Some casinos are operated by government-licensed organizations. Others are owned by private corporations.

In the United States, the word casino most often refers to a gaming facility containing table games such as blackjack and roulette, and electronic games like slot machines and video poker. In some cases, the term casino can also refer to a gaming facility located outside of the United States, such as in Europe or Asia.

Some communities welcome new casinos, as they provide jobs and money for local people and businesses. However, many critics claim that casinos do not bring in enough money to offset the cost of treating problem gamblers and other expenses. Furthermore, it is important to note that in some communities the majority of casino workers are from out of town. This can create problems with the local unemployment rate and wages.

Most casino owners and operators want to give their patrons a unique experience. They use interior design to create an upscale, exotic atmosphere and minimize the sense of passing time for their guests. For example, they may dim the lighting to create a more mysterious ambience. Additionally, they may offer a range of comps for frequent visitors that include free rooms, meals, tickets to shows or even limo service and airline tickets.
