Best Sportsbook Sign Up Bonuses 2021

Since the explosion of online sports betting in the past few years, so many sportsbooks have come onto the scene. All of them are trying to do one thing: get you to wager with them.

In order to do this, many sportsbooks offer bonuses for new players.

However, not all bonuses are created equal. That's why we’ve put this page together to help you decipher which betting bonuses are the right fit for you to maximize your value when signing on with a new sportsbook.

Scroll down to take a quick look at our breakdowns of the current sportsbook bonuses available to new customers and start betting today!

Frequently asked questions about sportsbook sign up bonuses

On this page, we offer a lot of detail about the various types of sportsbook bonuses you can expect to find. But, if you're just looking for a quick answer to a common question, you can find that here.

What is the best sportsbook bonus?

That depends on what you're looking for, but here are some of our favorites:

  • Bet365 - Up to $500 in Bet Credits
  • PointsBet - 2 Risk Free Bets of up to $2,000
  • Unibet - Risk Free Bet of up to $500
  • 888 Sport - Risk Free Bet of up to $500

This is, of course, a very select list, so make sure to read further down and see which bonus is the best fit for you.

How do sportsbook sign up bonuses work?

Usually, sign up bonuses are credited to your account upon registering your account however, some require a promo code. These bonuses offer you some value and allow you to test out the platform while minimizing your own risk. Make sure to check out our reviews for complete information on how to claim each sportsbook's bonus offer.

What is sportsbook bonus turnover?

Turnover is the number of times the money or site credit received through a bonus offer must be wagered before you can withdraw it. For example a $50 risk free bet with a 2x turnover, must be wagered twice to full fill the turnover requirement - a total of $100 in bets.

When do sportsbook bonuses expire?

This can vary wildly from book to book, so there's no one-size-fits-all answer here. For example, 888 Sport's risk free bet offer expires after only 7 days. Meanwhile, Barstool Sportsbook's free bet sign up bonus is good for up to a year.

Yet another reason to make sure you read your T's & C's!

What is a qualifying wager?

Qualifying wagers are bets that make you eligible for certain promotions. For example, if a site was offering a free bet if your first bet over $10 loses, then your first bet over $10 would be your qualifying wager. The requirements of qualifying wagers can normally be found in the terms and conditions of your promotion.

What are referral bonuses? How do they work?

Referral bonuses are bonuses given when you utilize a betting site's "Refer-A-Friend" feature. Typically they require the new user to make a qualifying bet or deposit. After placing their first bet or deposit both the new user and the existing customer should receive a credit in their account.

Difference between bonuses for sportsbooks and casinos?

It's fairly straightforward - on most sites with both functions, the sportsbook and casino have completely separate bonus offers. They usually vary in value and turnover amount and you can typically only redeem one. Casino bonuses tend to be a little less friendly and have a lower possible monetary value and higher turnover requirement.

How do you turn a sportsbook bonus into cash?

Most sportsbooks require you to fulfill what's called a turnover or playthrough requirement. This requirement is the number of times your bonus money must be wagered in order for it to be converted back into cash. So if you gave a $10 free bet with a 2x turnover requirement, you must place bets equalling $20 in order for your bonus money to turn into cold, hard cash.

There are rare exceptions to this rule, with some sportsbooks not requiring any turnover. For example, Unibet users in New Jersey have access to a risk free bet of up to $500. They get refunded in real cash that they can immediately withdraw, while Unibet users in other states must fulfill a turnover requirement.

How do you choose your sportsbook sign up bonus?

Most sportsbooks offer users a sign up bonus to lure them into the site. But these welcome offers can come in many forms - risk free bets & deposit bonuses are perhaps the two most prominent types.

There are certain things to look out for when choosing a sportsbook bonus:

  • Maximum value - This is fairly simple - if you were to try to maximize your bonus, what would the highest possible value be. This aspect is fairly straightforward and offers with highest maximum values are certainly eye-popping. However, don’t just look at this number - there are many other elements to consider.

  • Qualifying bet/deposit minimums - Simply put, this is the money that qualifies you for a bonus. Obviously the lower, the better unless you are simply looking to maximize a matched bet. However, if a site is going to match your deposit, then it may not be a bad idea to put more than necessary into your account. Since money that is deposited typically can be withdrawn easily, there’s not a ton of downside to maximizing matched deposits if you can afford it.

  • Turnover - Also known as rollover or wagering requirement, this is the number of times the money or site credit received through a bonus offer must be wagered before you can withdraw it. Many sites only require a turnover of 1x, however some (like DraftKings) have much higher requirements, so this is definitely something to keep an eye on.

Sportsbook Bonus Turnover

Turnover is the number of times your bonus amount must be wagered before you can withdraw it as cash

  • Flexibility - In my opinion, this is one of the absolutely most important variables to consider when evaluating bonuses. Sites like PointsBet offer users a very high possible value, but even if that value is reached you can then only use it on one wager. On the opposite end of the spectrum you have a site like Bet365. The highest possible value of their sign up bonus may seem small in comparison to PointsBet. However, Bet365’s bonus allows you to divide up your free bet into as many small bets as you’d like, granting you much more freedom in the long run.

  • Minimum odds - Sites often set minimum odds to ensure your free bet credits aren’t just being used on -1000 sure things. This helps them ensure that they’re not just giving away free money.

Pro Tip
Ben Smith

Ben Smith

Study the minimum odds on your promotion. When using your free bet or bet credits, stay as close to these odds as possible. This will typically mean you're wagering on a very safe bet (likely at least -300), but you still work towards fulfilling your turnover requirement and converting your free bet credits into real cash you can withdraw or bet more freely.

It's not the sexiest way to use your free bet, but it is relatively safe and the most likely way to convert your credits into cash.

  • States - Many websites have varying sign up bonuses depending on the state from which you are wagering. Typically, the types of offers are the same, but there is a bit of variance in the dollar amount.

  • Other terms and conditions ALWAYS apply - Make sure you’re always reading the fine print when signing up for these promotions - you don’t want to meet all the minimums and then lose your free bet because the promotion had expired. Taking the five minutes to read the terms and conditions of your offer can save you a lot more time in the long run

Recommended Sportsbook Bonus

Bet365 Bonus

Up to $500 in Bet Credits

At Sportsbooks Online we think Bet365 offers users one of the best sportsbook sign up bonuses out there.

The max value isn't staggering by any means, but Bet365 allows users to divide up their bet credits however they choose. If you do receive the max value, you could theoretically spend them on one $500 bet or five hundred $1 bets.

All you need to do is deposit a minimum of $10 and place your first real-money wager. After your bet is settled, Bet365 will scan your account and match your highest deposit in the previous 7 days up to $500.

New customers only. Make a qualifying deposit (min $10), place bets to deposit value, once they are settled, matched amount in Bet Credits available to use. Bet Credits risk excluded from returns. T&Cs apply.


Best Sportsbook Free Bets

The most generous welcome offer across online sports betting sites is the free bet. The way they are portioned out varies depending on the site you're using. Some sites require minimum bets, while others don't

Some sites require you to place a risk free real-money bet first and will reward you with a refund in bet credits if you lose, while others simply reward you with a free bet after your first deposit.

As always, we cannot recommend enough that you read the specific terms and conditions of your promotion. All of the relevant requirements and details should be very easy for you to find.

What is the difference between a free bet and a risk free bet?
Patrick Corkery

Free bets are typically given out upon sign-up or first deposit, while risk free bets are a form of insurance in case your first real-money bet loses. For instance, a risk free bet up to $500 requires you to first place a real-money wager. If you lose that bet, you will be refunded up to $500 in site credits you can use to place other bets.

Conversely, free bets that match your deposit simply require you to deposit money into your account.

Sportsbook Free Bet No Deposit Offer

Barstool Sportsbook Promo

$10 No Deposit Free Bet with a
$1,000 Risk Free Bet

Controversial digital media brand has partnered with Penn National Gaming to capitalize on the growing sports betting boom in the US and launch their very own sportsbook.

Barstool's sign up bonus includes:

  • A $10 Free Bet with no deposit required
  • A Risk Free Bet of up to $1,000

Once you register your account, the $10 Free Bet will be in your account automatically.

Best Sportsbook Risk Free Bets

888 Sport Risk Free Bet

888 Sport Risk Free Bet Offer

Similar to the free bet, the risk free bet is a popular way to bring in new customers for online sportsbooks. In fact, this may currently be the most popular sportsbook bonus offer on the market.

Risk free bets can also be classified as bet insurance

Unlike typical free bets, risk free bets normally require the user to place a real-money wager first. From there, it's pretty straightforward. If you win, nothing special happens. Simply enjoy your winnings. However, if you lose, you will be refunded up to a set amount in on-site credits. In this way, a risk free bet can also be classified as a form of bet insurance.

More online sportsbooks are offering this welcome bonus now because it limits the amount of money they have to dole out to users by eliminating payments to players who win their first bet. However, we still think risk free bets offer users tremendous value by covering potential losses from their first wager.

Check out our list of some of the top risk free sportsbook bonuses below!

Best Sportsbook Deposit Bonuses

A way to enhance your value when joining up with a sportsbook is to take advantage of a deposit bonus.

A deposit bonus is, simply put, a bonus just for loading money into your account. Often times the dollar amount you put into your account will be matched by the sportsbook.

From there, the bonus amount is yours to spend how you like. However, you should take note that there is typically a higher turnover rate with deposit bonuses than free bets. DraftKings Sportsbook, for example, requires a turnover of 25x before your deposit bonus is converted into real, tangible cash.

Take a look at some of the best sportsbook deposit bonuses available today.

If you have a large group of friends that loves sports, I heartily encourage you to look into sportsbooks with Refer-A-Friend programs. It's a simple, easy way to maximize the monetary value of your sportsbook experience.

    Best Online Casino Bonuses

    For the diversified bettor, many sportsbooks also have casino functionality.

    The casino sites typically have their own promotions and bonuses. Since the rate of return in casino games is higher than in sports betting, these bonuses tend to be less lucrative and feature higher turnover requirements than sportsbook bonuses.

    Beware - often, you can only redeem the casino bonus or the sportsbook bonus - not both.
