A Casino Deposit Match Bonus is a popular promotional offer that allows players to receive additional funds when they make a deposit. Typically, the casino matches a percentage of the player's deposit, effectively doubling or even tripling their initial bankroll. For example, a 100% match on a $100 deposit gives the player an extra $100 to play with. This bonus enhances the gaming experience by providing more opportunities to win, but players should be aware of the associated wagering requirements and terms before claiming the offer.
