Online sportsbooks offer a variety of ways to give new players free money to start betting. These bonuses are intended to attract customers and encourage them to stick around long enough to make money. They are offered by a number of major US sportsbooks. The most common is the no-deposit bonus, which allows a player to place a wager without risking their own cash. The value of this bonus varies from site to site, but it usually has a reasonable playthrough requirement and expires in a short time.

There are other free money sportsbook offers, which are intended to reward existing players for bringing in new business. These include referral bonuses and deposit match bonuses. Referral bonuses work by giving a registered user a unique link to share with friends and family. If a friend or family member signs up using the link and makes a qualifying deposit, both parties receive a bonus. The value of these bonuses varies, but it is not uncommon for sportsbooks to offer up to $100 in bonus bets.

Deposit match bonuses are another popular way to bolster a sportsbook account. These offer a percentage of the first deposit, ranging from 50% to 200%. These are a great way to increase your bankroll when you’re just getting started, but it’s important to remember that the amount of the bonus must be rolled over at least once before it can be withdrawn. This is a standard requirement, and many sportsbooks have no problem adhering to it.

Bonus bets are a popular sign up bonus offered by a number of different sportsbooks. These are basically extra bets that can be used on futures or point spreads, but do not count towards your actual winnings. These bets are meant to give you a chance to win some additional money, but the amount you actually make will depend on the odds of your bet and the terms of the promotion.

Some sportsbooks also provide a first bet insurance, in which the company will reimburse your initial bet if it loses. These are sometimes called “no-sweat” bets and are designed to lure in new customers. These promotions can be fun to use, but they are not the most lucrative way to build your sportsbook bankroll. They can even be dangerous if you place a losing bet and end up having no real money to withdraw.

Some sportsbooks also boost their odds for certain bets, especially on high-profile events such as the Super Bowl. These are a great way to get some extra money on a bet, but they can backfire if you don’t know what you’re doing. Sharp sports bettors know when to take advantage of these bonuses, and they use them to maximize their profits. They also utilize an odds comparison tool to do their line shopping and find the best lines before placing a bet. This can save them from a costly mistake, and can help them be successful long-term.
