What does Cage mean in a casino?

In a casino, the Cage is the cashier area or cash desk department where a player’s money transactions are handled. This is usually where deposits, withdrawals, fund exchanges, and other payment-related operations connected to the account or gameplay are processed.

How is it understood in practice?

The term appears most often in general casino vocabulary and internal rules. In simple terms, the Cage is the place or function that handles money, not the game itself. That is why it is associated not with slots or table games, but with payment processing, balances, and the issuing of funds.
