A 10 Deposit Bonus is a promotional offer provided by online casinos or betting platforms, where players receive a bonus equivalent to 10% of their initial deposit. This incentive encourages new users to sign up and make their first deposit, enhancing their gaming experience with extra funds. For example, if a player deposits $100, they would receive an additional $10 in bonus money. However, it's essential to review the terms and conditions, as wagering requirements and restrictions may apply before withdrawing any winnings derived from the bonus.
