CASINO is a quantum Monte Carlo program developed by the Theory of Condensed Matter group at the Cavendish Laboratory in Cambridge. CASINO can be used to perform variational quantum Monte Carlo and diffusion quantum Monte Carlo calculations for both periodic and non-periodic systems.

In modern English, a casino is a facility which houses and accommodates certain types of gambling activities. The industry that deals in casinos is called the gaming industry. Casinos are most commonly built near or combined with hotels, restaurants, retail shopping, cruise ships or other tourist attractions. There is much debate over whether or not the social and economic consequences of casino gambling outweigh the initial revenue that may be generated. In the United States, some states that have high unemployment and budget deficits have turned to legalizing casinos, often in places that are not tourist destinations. Some casinos are also known for hosting live entertainment events, such as stand-up comedy, concerts, and sporting events.
