A 1 Deposit Bonus is a promotional offer provided by online casinos or betting sites, rewarding new players for making their first deposit. Typically, this bonus matches a percentage of the initial deposit, allowing players to start with extra funds to explore games or betting options. For example, a 100% bonus on a $100 deposit gives players an additional $100 to play with. This incentive not only enhances the gaming experience but also increases the chances of winning, making it an attractive option for newcomers looking to maximize their bankroll.
