What Is a Casino?


A casino is a building in which gambling takes place. It is usually located near or in conjunction with a hotel, resort, restaurant, retail shopping, cruise ship, or other tourist attraction.

Games & Slots

Casinos offer several types of games, including card games, dice games, domino games, and gambling devices such as the roulette wheel. Some of these games are banked, in which the house holds a stake and collects a share of the winnings; others are nonbanked, in which the house does not hold a stake.


In the United States, most commercial casinos and hundreds of tribal casinos offer daily and weekly poker events. Some of these games can be played on video screens, but the biggest live events take place in real casinos.

Statistical Analysis

Gaming is based on mathematics, so the odds of winning vary from game to game. In some cases, the odds of a player winning are better than the house expects.


The mathematical advantage that the casino has over the players is called the house edge. It is designed to reduce the short-term risk of losing money by ensuring that the casino makes more profit on the long run than it loses on the games.

Bonuses & Rewards

A casino’s bonuses and rewards are designed to encourage gamblers to play more often and spend more money. They include free entertainment, transportation, luxury suites, and other incentives. These incentives are also used to attract high-stakes gamblers, who are a profitable source of revenue for casinos.
