Arguably the most common bonus for online sportsbooks is the humble Welcome Bonus. You can find them at basically all of the U.S. Sportsbooks and they are typically available to first-time bettors who sign up for a new account.
For example, in New Jersey, most online sportsbooks offer a Welcome Bonus typically in the form of a "Risk-Free Bet" or a “Deposit Bonus” as a welcome bonus.
How Welcome Bonuses Work
Welcome bonuses work as an incentive for new players to register and start betting. If a sportsbook offers a 100% deposit match up to $250, this means the $250 will give the bettor an additional $250, albeit in bonus funds, in their betting account. These bonuses typically have terms and conditions, like wagering requirements or minimum odds, which must be met before the bonus can be fully utilized or any winnings withdrawn.
