A casino online deposit bonus is an enticing promotion offered by online casinos to attract new players and reward existing ones. Typically, this bonus matches 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. These bonuses often come with specific wagering requirements, meaning players must bet a certain amount before withdrawing any winnings. Overall, deposit bonuses enhance the gaming experience, offering more opportunities to win while enjoying a variety of casino games.
