A Casino is a gambling establishment where patrons can exchange money for chips or credits to play a variety of games. Some casinos also offer entertainment shows and dining options. Most states have laws regulating the types of gambling offered and the minimum age for gambling.

The house edge of a casino game is the advantage that the house has over the player, expressed as a percentage of the total amount wagered. In games with a skill element, players can eliminate the house edge by learning to play optimally. This is done by analyzing the game rules, the specific strategies required to win and, in some cases, by using statistical analysis. Those who do this are known as advantage players.

Some casinos have automated systems for some of their table games to ensure that the odds are as expected; this is known as “chip tracking” or “table monitoring.” The house edge and variance of a game can be calculated mathematically. This is done by specialists in the field, called gaming mathematicians and analysts.

In the US, the number of casinos is growing rapidly. Many states are legalizing casino gambling, and Las Vegas continues to dominate the industry. Atlantic City, New Jersey and Chicago are other major centers. In addition to traditional casinos, some American Indian tribes operate casinos.
