What Is An Online Sportsbook Bonus?
An online sportsbook bonus is an incentive offered by sportsbooks to new and existing players.
Sportsbook bonuses are typically offered for three reasons:
- To get new players to sign up.
- To get players to make a deposit.
- To keep existing players betting.
In return, the betting site promises to credit your account with either bonus cash, or real money upon fulfilling a set of terms and conditions.
Types Of Online Sportsbook Sign Up Bonuses
Please be aware that the majority of online sportsbook bonuses are exclusively for new players. This is because sportsbooks are always looking to attract new customers.

How To Claim An Online Sportsbook Bonus
Due to there being multiple types of sportsbook bonuses, there is no set way to claim one. The first thing you need to do before you claim is to figure out which process you have to follow.
Here’s an overview of the most common processes:
Lose a Wager
Risk free bets require you to sign up, make a deposit, and then lose your first bet before you receive any bonus funds.
Pro Tip
Where can I find the bonus code?
Bonus codes (or, promo codes) can be found in our list adjacent to its corresponding bonus. If a bonus code is not featured alongside a bonus, it means the bonus does not require one. You can identify bonus codes by looking for a random sequence of numbers, letters or both. Here are a few examples:

Terms & Conditions For Sportsbook Betting Promotions
The only way to find the best sportsbook bonus is to compare the terms and conditions and pick the most favorable bonus. This is because the only way to win real money with your bonus is to satisfy the t&c’s.
Here are the main terms and conditions you have to be aware of:
Not only can bonuses change depending on your state, but in many US states online gambling is not yet legal. In legal states, the bonuses offered by the same company tend to be very similar.
Bonuses such as risk free bets may stipulate that you can only make wagers on outcomes with odds above a certain value. Attempting to make a wager with superior odds may invalidate your bonus.
After a set period of time your bonus may expire. Please ensure you wager your bonus before the expiry date is met, or else you will lose the opportunity to use it.
Certain bonuses, such as match deposit bonuses and risk free bet bonuses, require you to make a deposit. This deposit must meet, or be greater than, the minimum deposit stipulated in the bonus’ terms and conditions.
Sportsbooks may place restrictions on what you can wager on using your bonus. Any types of bet that are particularly favourable may be disallowed.
Most bonuses will either imply or state the maximum you will be able to receive in bonus credits/cash. While the biggest bonus is not necessarily the best to claim, when two bonuses are similar it may be best to claim the biggest.
While sportsbook bonuses allow you to win real money, your sportsbook may cap your winnings to a maximum value. You will not be able to withdraw winnings that exceed this value.
Any sportsbook bonus that credits your account with bonus cash may require you to wager the value of your bonus a number of times.
For example, if you receive $100 in bonus credits, and the wagering requirement is 2x, you have to wager $200 (2 x $100) using your bonus before you can withdraw your winnings.
FAQ
Yes, absolutely! Many of the legal sportsbook bonuses on our list are incredibly generous, giving you the chance to make your first bet risk-free, or doubling the value of your deposit.

It depends. There are many types of online sportsbook bonuses, each of which has its own advantages and disadvantages. Perhaps the most popular type of bonus at online sportsbooks are risk free bets, with our current favourite being UniBet’s risk free bet offer which refunds you in cash up to $500!
Bonus cash is what you receive when you claim an online sportsbook bonus – providing the bonus terms do not state otherwise. Bonus cash is not exactly the same as real money because it holds no value outside of the sportsbook. The concept is similar to having vouchers you can use at a restaurant or retail shop.
Most often, you can convert bonus cash into real cash by fulfilling a set of terms and conditions.
It depends on the type of bonus you claim. The general idea is that you create a new account, make a deposit, or lose a wager, and in return you will receive either real money or bonus cash.

Yes, absolutely! Most online sportsbooks have purpose-built apps which allow you to claim any of their welcome bonuses. However, you do not have to download an app. Sportsbooks design their site with HTML5 technology, allowing you to access all content through your mobile browser.

Helene Grinstein – Sports Betting Journalist
Of all the current sportsbook bonuses, my favourite is UniBet’s offer of a $500 risk-free bet. While the value of UniBet’s risk-free promotion is not as large as other sportsbooks, its 1x wagering requirement is very generous.
Moreover, players in New Jersey don’t even have to worry about wagering requirements. The offer of a cash refund is unusually openhanded, and quite the invitation. This is the offer I currently recommend to my friends.
