Casino sites often offer deposit bonuses to attract new players and reward loyal customers. These bonuses typically match a percentage of the player's initial deposit, providing extra funds to explore games and increase winning potential. For example, a 100% deposit bonus on a $100 deposit gives players an additional $100 to play with. However, it's essential to read the terms and conditions, as wagering requirements and game restrictions may apply. Overall, deposit bonuses enhance the gaming experience, allowing players to maximize their bankroll and enjoy more time at the casino.
