Gambling deposit bonuses are enticing offers provided by online casinos to attract new players and retain existing ones. These bonuses typically match a percentage of the player's initial deposit, allowing them to play with extra funds. For example, a 100% deposit bonus means that if you deposit $100, you receive an additional $100 to gamble with. This incentive not only enhances the gaming experience but also increases the chances of winning. However, it's essential to read the terms and conditions, as wagering requirements and restrictions may apply.
