Casino

A casino is a venue offering games of chance and skill in which participants wager money or other valuables, typically against the house or one another.

House edge: The average proportion of wagers a gambling operator expects to retain over repeated play. It gives casinos a statistical advantage in many games, even when individual outcomes remain uncertain.
Slot machine: A gambling machine that accepts wagers and awards outcomes determined by chance, traditionally through spinning reels. Slots are a prominent casino game format, often organized in large dedicated floor areas.
Ridotto: A state-operated public gambling house opened in Venice in 1638. It is often identified as an early public venue resembling the regulated casino.
Gambling addiction: A behavioral disorder characterized by persistent gambling despite serious personal, financial, or social harm. Casino access can contribute to gambling-related harm for people who develop this disorder.
Lottery: A gambling system in which participants buy chances to win prizes selected by a random drawing. Lotteries rely on periodic drawings rather than the continuous games typical of casinos.
Expected value: The probability-weighted average of the possible outcomes of a decision or gamble. It explains why a game can be fair on each round yet profitable for the casino over time.
Poker: A family of card games in which players wager on hands ranked by established rules. Casino poker rooms host games where players generally compete against one another.
Casino di Campione: A casino in Campione d'Italia, founded in 1917 and later housed in a landmark building. Its history illustrates the spread of casinos beyond their early European centers.
Gambling law: The body of laws governing gambling activities, operators, wagers, and related enforcement. Casinos depend on legal permission and ongoing compliance with jurisdiction-specific rules.
Sports betting: Wagering on the outcomes or events of sporting contests. It centers wagers on external sporting events rather than games staged by a casino.
