Unlike Internet or other forms of gambling, casino gambling requires social interaction, so players are usually surrounded by others. They are also often surrounded by alcoholic beverages, though sometimes non-alcoholic drinks are provided free of charge. Often, the casino atmosphere is designed to be noisy, exciting, and filled with energy. Moreover, casinos use gaudy colors like red to create a festive atmosphere. This effect of red has a positive effect on the mood of casino goers.

The games available in a casino vary depending on the casino and the software. The most common games include slots, blackjack, and various table games. There are also specialized casinos that specialize in creating and introducing new games. Various state laws govern the rules and payouts for these games. Some casinos have arcades. Others list their casino games separately. Some casinos even have games that are unique to the casino. In addition to slots and table games, casinos also offer lottery games and specialty games.

There are numerous security measures in a casino. One method involves elaborate surveillance systems, which let security personnel keep a constant eye on every game. Cameras are positioned throughout the casino, and can be adjusted to focus on suspicious patrons. They also record video feeds for later review. Additionally, the payouts at the slot machines are determined by computer chips inside the machine. The casino staff is not allowed to observe the floor of slot machines. This makes security measures even more important.
