This SI Sportsbook review will help you decide if it is the right sports betting app or website for your needs. We will highlight the bets you can place, the odds it provides, the sign-up bonus, the additional promotions and contests, the deposit and withdrawal options and betting limits, the payout speeds and the overall quality of the customer’s online betting experience. Continue reading to learn everything you need to know about Sports Illustrated Sportsbook.

Sports Illustrated Sportsbook Overview

888 Holdings is a London-listed company that owns internationally renowned brands including 888 Casino, 888 Sport, 888 Poker, William Hill and Mr Green. Four Israeli entrepreneurs founded the business in 1997, and it is now one of the largest operators in the global online gambling industry. The company initially launched its flagship 888 Sport brand when it expanded into the U.S. market in 2018. However, that brand struggled to keep pace with popular rivals such as FanDuel, DraftKings and BetMGM, so 888 Holdings changed its strategy.

In June 2021, it announced plans to launch Sports Illustrated Sportsbook after tying up a deal with Authentic Brands (ABG). The partners agreed to a joint venture lasting at least 20 years. ABG, which purchased the Sports Illustrated brand for $110 million in 2019, took a 4.99% stake, with 888 Holdings owning the rest. The agreement states that ABG can ultimately increase its share to 14.99%, but 888 is running the show.

It gained exclusive rights for Sports Illustrated’s digital channels, the print magazine and all associated brands for sports betting and online casino gaming in the United States and Canada. SI Sportsbook launched in Colorado, before expanding into Virginia and Michigan. There are plans for a broader expansion of the brand soon, with New Jersey, Indiana and Iowa touted as future destinations.

What types of bets can you place at SI Sportsbook?

888 Holdings built the SI Sportsbook app and website on the same proprietary technology it uses for the 888 Sport brand. It has the same layout and betting options, but a different color scheme and significantly better bonuses. The sportsbook covers 22 different sports, from Aussie Rules and badminton to table tennis and volleyball.

SI Sportsbook also covers lots of different basketball, baseball, soccer and hockey leagues. For example, you can bet on basketball in Turkey, Croatia, Greece, Poland, Japan and South Korea, among other countries.

The soccer section is vast, featuring lower-league games from all over the world. It offers a very broad array of betting options on NFL, NCAAF, NBA, NCAAB, MLB and NHL games. These are the key betting categories available to SI Sportsbook users:

Straight Bets

A straight bet is a single wager on an individual sports event, such as a baseball game, a boxing bout or a tennis match. These are the three most popular options for SI Sportsbook customers:

  • Moneyline
  • Point Spread
  • Total (Over/Under)

A moneyline bet just requires you to predict the winner of the event. For example, you might find -150 on the Dallas Cowboys to beat the Tampa Bay Buccaneers and +130 on the Bucs to win the game. The odds inform you of the profit you would earn by making a winning bet.

A spread bet gives the moneyline favorite a handicap to level things out. Continuing with the example used above, you might expect to find -110 on the Cowboys -2.5 and -110 on the Buccaneers +2.5. A bet on Dallas would require it to win by 3 or more, whereas a bet on the Bucs would pay out if they won or lost by up to 2 points.

A totals bet is a simple over/under wager on the number of points, runs or goals in a game, a half, a quarter, a period, an inning or any other portion of an event. SI Sportsbook sets a total line, such as 45.5 points, and you can bet over or under, with similar odds on each outcome.


Parlays are multiple bets that combine two or more selections on separate sporting events. For example, you could bet on the Seahawks, the Jaguars, the Dolphins and the Bengals all to cover the spread on the same day. All four need to cover for your parlay to succeed, and you will earn a large cumulative payout if they do.

You can also use the bet builder at SI Sportsbook to put same-game parlays together, combining multiple picks on the same event. Teasers and round robins are available too.

Prop Bets

Props focus on events within a game, but they are not specifically linked to the result. There are game props, team props and player props. SI Sportsbook offers a large choice of prop bets on football, baseball, basketball and hockey games. For example, when you venture into an NFL game, you will find these player prop categories:

  • Game Touchdown
  • Touchdown Scorer
  • Player Passing
  • Player Receiving
  • Player Rushing
  • Player Rushing & Receiving
  • Player Kicking Points

Basketball games feature a similar volume of options, including player points, assists, rebounds, threes made, steals, blocks, turnovers and combinations of those stats.

Futures Bets

These are long-term bets placed on markets that run throughout the season. They are not dictated by the outcome of a single game. For example, SI Sportsbook offers these NBA futures options:

  • NBA Championship Winner
  • Western Conference Champion
  • Eastern Conference Champion
  • Divisional Winners
  • Coach of the Year
  • Defensive Player of the Year
  • Rookie of the Year
  • Sixth Man of the Year
  • Most Improved Player
  • Coach of the Year

The odds are updated throughout the season, and you can continue betting on them until the winner is decided.

SI Sportsbook Live Betting

SI Sportsbook has a very strong in-play betting section, featuring a clear layout that is easy to navigate. The interface lists all the live events you can bet on and the choice is vast, covering football, basketball, baseball, hockey, soccer, golf, tennis and many more sports.

There are more than 100 live markets available on football and basketball games, while you can find over 50 live markets on high-profile tennis matches. Even second-division Mexican or Japanese soccer matches can come with around 50 in-play markets, which illustrates the depth of the live betting coverage at SI Sportsbook.

You can stay up to date with the action through live infographics, scores and stats. Pages load up quickly and it is easy to make your plays before the odds change, so it is an impressive all-around live betting app.

SI Sportsbook Bonuses & Promotions

SI Sportsbook Sign-Up Bonus

You can normally choose from a variety of different welcome bonuses at SI Sportsbook. At the time of writing, there are two different options:

Bet $20, Win $200 |Sign up for an account and place a $20 bet at minimum odds of +120 to qualify for this welcome bonus. If your bet wins, you will receive $200 in bonus bet tokens after it settles.

Take Home History | Place a $20 bet at minimum odds of -200, and you will receive a framed Sports Illustrated magazine cover of your choice. The magazine cover has a $200 value, according to SI Sportsbook. You can alternatively bet $10 at minimum odds of -200 to earn a printed Sports Illustrated magazine cover worth $100.

You can only claim one of these welcome bonuses, but they are both appealing, and it is great to be offered a choice of options.

Sports Illustrated Magazine Covers

Existing players can also earn a printed Sports Illustrated magazine cover worth $100. You just need to place 22 wagers worth $20 or more to qualify, while ensuring you hit minimum odds of -150 with each wager. You will then receive a one-time credit worth $100 to spend at

Betting Insurance

There are lots of insurance deals available at SI Sportsbook. They earn you a full or partial rebate if your wager is unsuccessful. These are some of the promos available to all Sports Illustrated Sportsbook customers:

  • A full rebate if your single-game parlay worth $10 or more on college football loses.
  • A 100% rebate of up to $20 on losing NBA same-game parlays each Tuesday.
  • A full rebate worth $10 if your NFL primetime same-game parlay loses.
  • A 33% rebate of up to $100 if your live wager on any sport apart from soccer or tennis loses.

Rebates are paid in the form of bonus bet credits, with a 1x rollover requirement.

Odds Boosts

There is an “SI Sportsboosts” tab, where you can find boosted odds on various parlays and same-game parlays. For example, you might find the Wizards, Bucks, Kings and Nuggets all to win, boosted from +450 to +500. Another option could be the Nuggets to cover an 8.5-point spread and Nikola Jokic to score 30+ points, boosted from +340 to +400.

A lot of these boosts are state-specific, so you will often find enhanced odds on the Broncos, Avs, Nuggets and Rockies in Colorado, for instance.

Perfect 10 Contest

This is a free-to-play contest, which gives you chances to win bonus bets. You will be asked to make 10 predictions on an upcoming event by answering questions, and it will give you $1 in bonus credits each time you get one correct. If you nail all 10, you will win a share of the $10,000 top prize. Should you be the only customer to guess all 10 correctly, the entire $10,000 is yours.

Bonus Bets

There are various ways to earn regular bonus bets as a Sports Illustrated Sportsbook customer. For example, it offers $150 in weekly bet credits during the NFL playoffs. Customers need to place same-game parlays with cumulative odds of +300 or higher to qualify. These are some of the other Bonus Bet bonuses that have recently been available to existing players at SI Sportsbook:

  • A $10 bonus bet each week for 18 weeks during the NFL season. Customers needed to place a $20 bet at odds of -150 or greater to claim it.
  • A $20 bonus bet each week if a customer wagered $100 or more on NBA and NHL games.
  • Three & Win, whereby SI Sportsbook gave customers $20 in bonus bets each week if they placed a winning parlay with three or more legs between Friday and Sunday.
  • An NFL bet builder offer, which earned players a $5 bonus bet for wagering $25 or more on a same-game parlay.

SI Sportsbook App

The SI Sportsbook app has been built upon 888’s proprietary technology, which is used to power the 888 Sport brand. 888 Holdings acquired the software when it completed a deal to buy Irish bookmaker BetBright. At the time, 888 Sport ran on a white-label sportsbook platform provided by Kambi, giving it the same user experience and odds as rivals such as Unibet and BetRivers.

However, it was then able to migrate to in-house technology, meaning it no longer needed to pay Kambi a cut. The odds have now improved, and it offers a unique mobile wagering experience. It has kept one of the best tools from the Kambi platform, a widget that allows you to create alternative spreads and totals by dragging a dot along a line, and the layout is similar but a little easier to use.

The result is a very impressive mobile app. It is accessible, the navigation is simple and it is full of great features. You should be able to place bets quickly and easily when using this reliable mobile sports betting app. It performed well on all the devices we used when testing it out. Pages loaded quickly and we did not experience any location issues.

Download the Sports Illustrated Sportsbook App

You can download the SI Sportsbook app by visiting the Google Play store on an Android device or the App Store on any iPhone. Android users have given it an average rating of 4.3, and it has an average user rating of 3.9 on the App Store.

The app is free to download. It will take up 30 MB of storage space on your device, and it only needs to be upgraded on an occasional basis. You can alternatively visit the mobile site if you do not want to use up storage space.

SI Sportsbook App Features

If you’re a sports bettor looking for a good mobile experience, you’ve come to the right place. There are lots of different SI Sportsbook features offered when you download this mobile sports betting app:

Same Game Parlay Builder | The bet builder tool allows you to create same-game parlays on a variety of major sports leagues with ease.

Bet Feed | SI Sportsbook will display trending bets in real-time, allowing you to see the most popular wagers placed by your peers. This may provide you with inspiration for your bets, and it also highlights opportunities to fade the public. You can customize your feed to only show the sports that interest you.

Cash Out | You can cash out open bets at SI Sportsbook while the game is live. This allows you to secure a guaranteed payout if your bet is on course to win, or you can cut your losses if a bet is on course to fail.

Light and Dark Mode | You can change the aesthetic from light to dark at any time, according to your preferences.

Sports Illustrated Sportsbook Customer Service

SI Sportsbook offers limited customer support options. There is no phone line, and the online sportsbook site does not have a live chat service either.

That means your only option is to fill out a form on the site and wait for the customer service team to reply. Many rivals will provide instant, 24/7 support over live chat, so this is a weak spot for SI Sportsbook.

Where is SI Sportsbook legal?

SI Sportsbook is currently available in three states:

  • Colorado
  • Michigan
  • Virginia

When it launched in Colorado back in 2021, the company announced plans to roll its online sports betting operation out into Indiana, Iowa and New Jersey soon. It discontinued the 888 Sport app in New Jersey in preparation for a Garden State launch, but that has not yet materialized. 

Instead, it expanded into Virginia in May 2022. It then launched in Michigan four months later via a market access deal with the Hannahville Indian Community, which runs the Island Resort & Casino in Harris. The tribe previously partnered with TwinSpires, but it switched to SI Sportsbook after TwinSpires exited the sports betting business.

SI Sportsbook is still expected to launch in New Jersey and other states, so we will update readers when it does.
