A sports bet deposit bonus is an enticing promotion offered by online sportsbooks to attract new customers and reward existing ones. Typically, it involves matching a percentage of a player's initial deposit, providing extra funds to wager on sports events. For example, a 100% deposit bonus up to $200 means that if you deposit $200, you receive an additional $200 in bonus funds. This bonus enhances the betting experience, allowing players to explore more betting options and increase their chances of winning. However, it's essential to read the terms and conditions, as wagering requirements may apply.
