A sports deposit bonus is a promotional offer provided by online sportsbooks to attract new customers and reward existing ones. Typically, it involves matching a percentage of the initial deposit made by a user, allowing them to have extra funds to place bets. For example, a 100% deposit bonus up to $200 means that if a user deposits $200, they receive an additional $200 in bonus funds. These bonuses often come with specific wagering requirements, encouraging users to engage more with the platform before withdrawing any winnings. Always read the terms and conditions to maximize the benefits.
