The term locals casino is most often used in Nevada, USA, a state known for Las Vegas and numerous gambling establishments, and is used to differentiate between brick-and-mortar casinos that cater to the needs of local players and the casinos built for tourists.
For example, players visiting Las Vegas for the first time usually look for a casino characterised by the glamour and luxury or perhaps its size, dining areas, extravagant lobbies, and so on. However, local players who have seen such casinos countless times don’t care much about those things. Instead, they choose to try their luck in establishments that offer better odds or have a bigger variety of games.
Casinos focused on the games rather than the experience and the environment is what the players call locals casinos, while they refer to the other type of casinos as tourist casinos.
