Balance in casino is the amount of money currently available in the player’s account. This is the money used for bets, bonus feature purchases, and other game actions.

The balance changes after every spin, wager, deposit, withdrawal, or bonus credit. If there is 50 EUR in the account, that is the amount available for play until part of it is used on bets or new winnings are added.

The term is simple, but fundamental. Balance shows how much money is actually available right now, not how much was originally deposited or won over the full session.
