A 100 Percent Deposit Bonus is a promotional offer commonly found in online casinos and betting sites, where the operator matches your initial deposit amount, effectively doubling your funds. For example, if you deposit $100, you receive an additional $100 in bonus money, giving you a total of $200 to play with. This bonus enhances your gaming experience by providing extra funds to explore various games or betting options. However, it's essential to review the terms and conditions, as wagering requirements and restrictions may apply before you can withdraw any winnings derived from the bonus.
