What Is a Casino?


A casino is a gambling establishment that offers players the opportunity to try their luck at games of chance. It often offers a variety of amenities and is located near hotels, restaurants, retail shopping, and cruise ships.

Casinos cater to high-stakes gamblers and offer them perks like free rooms and show tickets. These perks are designed to encourage patrons to spend more money than they would otherwise.

Games offered

Casinos offer a variety of gambling games, including card games, dice games, domino games, and slot machines. Some of these games are banked, meaning the house takes a percentage of the total amount wagered, while others are not. Banked games include blackjack, craps, keno, and roulette. In addition, some casinos also offer a variety of nonbanked games, such as two-up and baccarat. These examples were programmatically compiled from online sources and may not reflect the opinions of Merriam-Webster or its editors. The word casino is most often used to describe a gambling establishment, but it can refer to any type of facility that offers games of chance.

Security measures

Casinos take many security measures to ensure the safety of their patrons. These include implementing sophisticated surveillance technologies and employing highly trained personnel. They also conduct regular vulnerability assessments to identify and address potential cybersecurity risks.

In addition, casinos utilize innovative tools to help prevent fraud and theft. One such tool is the Indoor Positioning System (IPS). IPS provides accurate real-time location tracking, making it easier for casino security to monitor and respond to suspicious activities. This technology also helps in identifying high-value assets and streamlines asset management processes.

Another way that casinos enhance security is by providing safe deposit boxes or lockers for patrons to store their belongings during their visit. These secure storage options help patrons relax and focus on their gaming experience without worrying about stolen items. In addition, casinos offer comprehensive training programs to teach employees about security protocols and how to spot suspicious behavior. They also encourage their staff to communicate with each other promptly and effectively.


Casino comps, short for complimentary, are additional benefits that casinos offer to encourage gamblers to spend more money. These perks can include free rooms in the casino hotel, meals, gift items, and even cruises. To get comps, a player must enroll in the casino’s players club and swipe their card every time they gamble. The card has a magnetic stripe that the dealer uses to record the amount of money a player spends.

Comps vary depending on the amount of play and tier level, with higher-tier players getting more generous offers. At the lowest level, a comped cocktail is given to anyone who gambles for an hour or more, while high rollers are pampered with everything from limo transportation to free hotel stays and meals. Other comps may include free gifts, resort credit, and special promotions. Casinos budget anywhere from 20-30% of their revenue for comps.
