A Bookies Deposit Bonus is a promotional offer provided by online sportsbooks to attract new customers and retain existing ones. Typically, it involves matching a percentage of the initial deposit made by the user, allowing them to have extra funds to wager on sports events. 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 they can withdraw any winnings derived from the bonus.
