Overall Rating

Author: Avery Hutchison Avery Hutchison

With a copy of its magazine taking a prominent spot on newsstands and waiting room tables alike since the first publication in 1954, Sports Illustrated has now partnered with 888 to bring you its very own sportsbook.

Still an early foray into the well established industry of online sports betting, SI Sportsbook is relying a little on the nostalgia factor and brand name to get past some teething struggles, but seems poised to build off a great initial outing when it manages to expand into more states and iron out a few of the kinks that let this new bookmaker down.

SI Sportsbook Promo FAQ

With the abundance of promos on SI Sportsbook, there are always a few questions - here are the most common questions and answers for all things promo related

Do I need a SI Sportsbook promo code?

No, you no longer need a promo code to claim the SI Sportsbook welcome offer. Just hit one of the green buttons on this page and you'll be redirected to the betting site ready to claim the offer.

How many times can I enter the Perfect 10?

You can make a selection for the Perfect 10 promo each period it is running. This usually means each week! And there are no requirements to enter, but if you want to claim the $1 free bet for each correct answer you do need to wager $25 through the week.

How do I claim the SI Sportsbook promo?

For most SI Sportsbook promos you just need to fulfill the qualifying bet, which may include:

  • what events are eligible
  • how much you need to wager
  • minimum odds

For example, to claim the welcome bonus, you need to sign and:

  • wager at least $10

Once you do this you'll be eligible to claim the free bet!

Does SI Sportsbook have free bets?

Absolutely. SI Sportsbook has a ton of free bet promos, and pretty much all rewards and refunds from parlay insurance are given as free bets.

Remember that even though a free bet is a wager without risking your own money, you can only withdraw winnings.

SI Sportsbook Free Bets

When bettors see the term free bets, it almost always puts a smile on their faces. And why wouldn't it? Free Bets allow you to place a wager without risking any of your own money. So if you see a chance to scoop up a pile of free bets from a promotion, it's always worth checking out. 

SI Sportsbook has one of the most diverse promotion portfolios in the sports betting industry right now, which is impressive given the betting site is still quite small. You can expect to claim free bets from a variety of promos, like bet and get promos.

Here are a few examples of SI Sportsbook free bet bonuses:

SI Sportsbook Bet and Get Promos

Si sportsbook big fly promo

You don't get promotions much simpler than a classic 'bet and get.' And one of the great things about SI Sportsbook is they offer this style of promotion as their welcome offer and as an offer for existing users

The reason getting free bets from a promo like this is that you don't really need to go out of your way to fulfill crazy requirements, you can generally get the bonus just by betting normally. But it's also a great way to try out different sports or ways to bet knowing you'll always have a little coming back. 

To claim the Big Fly promo all you needed to do:

  • Wager cash bets of $10 on MLB baseball at -150 or higher
  • For the first 3 bets claim $10, after 5 free bets claim $5, after 7 bets claim $10, after 10 bets claim $15
  • Claim up to a total of $40 each week!

This kind of free bet promotion is worth looking out for on SI Ssportsbook, as they occur regularly and allow you to claim bonus money each week.

Different Sports for Different Seasons

SI Sportsbook is one of the best betting sites when it comes to keeping their promos relevant to current sports being played. Sometimes we find that there are generic promos you can find on certain betting sites, but SI keeps things fresh by changing their offers all the time.

During the NFL season you can expect numerous promos for football, and during an event like the World Cup you'll find bonuses related to soccer!

SI Sportsbook Parlay Promos

While we have some reservations about the quality of parlay betting with SI Sportsbook, there is no denying they offer a great range of parlay promos that make up for the somewhat limited market selection. 

You're not limited to Parlay Insurance on SI Sportsbook, there are also parlay promos you can claim each day for winning wagers. 

SI Sportsbook Parlay Insurance

Here how to claim this Parlay Insurance promo:

  • Wager $10 on a MLB parlay (3 legs, +300 odds or higher)
  • If that loses, earn $10 in free bets to use

You did read that right, this is 100% of your bet stake back! And it gets even better since you can claim this promo once per week. 

SI Sportsbook Three and Win

Si sportsbook three and win promo

The SI Sportsbook Three & Win parlay promo breaks out of the norm a bit, and rewards you for winning parlays. This is a great example of how SI Sportsbook takes fairly normal promotions and adds a slight twist to give users extra value. 

Similar to a 'bet and get' promo, the Three & Win has you wager on a parlay, and claim additional free bets if you win - each weekend. 

Here's how it worked:

  • Wager $25+ on a parlay (3 legs, +300 odds or higher) between Friday and Sunday
  • If that bet wins, earn $20 in free bets!
  • Available each day over the weekend
SI Sportsbook Bet Builder

SI Sportsbook has a bet builder feature to help you create parlays on NFL and NBA game, but there are often associated promotions that come with using the bet builder tool.

We've seen examples like:

  • $5 free bet for making a $25 wager with the NFL bet builder
  • Free bets for using the bet builder on NBA games

SI Sportsbook Perfect 10

Si sportsbook perfect 10 promo

The SI Sportsbook Perfect 10 promotion is an incredibly unique and fun offer, and we can't rave about it enough for how much value you can get if you win. 

The SI Sportsbook Perfect 10 promo gives you the chance to win a share of $10k totally free! All you need to do is make ten correct picks from the selection and you can enjoy some cold hard cash hitting your account.

You'll also get a $1 free bet for each correct pick!

Whats the Catch?
Avery Hutchison

Avery Hutchison

We're happy to say there really isn't a catch with the Perfect 10, you can enter each week without needing to do anything aside from having an account with SI Sportsbook.

Here's how it works:

  • Make your 10 picks in the Perfect 10 menu
  • Earn a $1 free bet for each correct guess
  • Split a $10k cash prize if you guess all correctly!

After your first two entries into the Perfect 10 game, to receive Free Bet tokens you must have placed qualifying bets totaling $25 during the respective week, but that is a super low betting requirement for the potential to win $10,000 in cash, and the bonus free bets are really just icing on the cake.

SI Sportsboosts

Every good betting site needs to offer odds boosts and profit boosts to really say they have all the bells and whistles. 

SI Sportsbook puts these boosts into a group called SI Sportsboosts
