SI Sportsbook Review & Promo Code 2022

Partnering with 888sport, SI Sportsbook made its way into the sports betting world in 2021. There is a lot to like about SI Sportsbook, including a unique intro promo for new customers, various sports and markets to bet on, and many banking options for deposits and withdrawals. 

The online sportsbook promotion is currently only available in Colorado but we expect it to expand into other states with legal sports betting in the coming months.

This SI Sportsbook review covers everything you need to know to decide whether this online sportsbook is right for you.

Pros and Cons of SI Sportsbook

  • Live betting & cashouts available
  • Wide range of sports & markets
  • Beginner-friendly site
  • Smooth banking experience
  • Backed by trusted sports media
  • Limited customer support
  • Withdrawals processed slowly
  • In-play betting lacks live stats
  • App performance issues

Editors Conclusions: SI Sportsbook Offers Profitable Bonus


SI Sportsbook has an intro bonus for new customers that requires much less of an upfront investment than any other bookers and no promo code at all.

The online sportsbook also offers great promotions and odds boosts, various sports and markets, a decent user interface, and many educational resources for bettors. We recommend using it alongside at least one other book so you can shop around for the best odds before placing bets.

SI Sportsbook is licensed to operate in Colorado, with further expansion plans in the works. Secure SSL encryption software keeps personal and financial details safe while backing from 888 Holdings instills confidence in the platform

Bonuses and Promos at SI Sportsbook

SI Sportsbook offers a large selection of event and sport-specific promotions. Parlay insurance and odds boosts are offered for certain leagues or games, as well as risk-free bet tokens if certain prop bets fail to payout.

Be sure to check out SI Sportsbook’s official promos page for an up-to-date list. Since promotions are state-specific, you might see advertisements for promos that aren't available in your state.

Here are some of the current promotions at SI Sportsbook.

SI Sportsbook - Bet $10 Get $50

New SI Sportsbook users get $50 in free bets right after placing their first $10 wager. After making your first deposit with SI Sportsbook, place a qualifying bet of at least $10 within seven days.

SI Sportsbook is licensed to operate in Colorado and Virginia, but this promotion is only available in Colorado.

Promo Offer:Sign-up bonus, Bet $10 Get $50
Promo Code:None Needed - Use Link
Selected Events: All
Eligible States:CO
Min. Deposit:$10
Wagering Req.:
  • Free bets have a 1x rollover requirement. Any winnings can be withdrawn after wagering them once.
  • Only profits from free bets are paid out, not the amount wagered.

Despite being relatively small, we actually consider the SI welcome bonus as one of the best in the state. That’s because it only costs you $10 to claim $50 in free bets. Even better is the fact that your opening bet can win and you still get the $50 in free bets, unlike some operator welcome offers where the bonus only kicks in if your bet is unsuccessful.

The following conditions must be met in order to claim this offer without a promo code:

  • New users only, shall meet the minimum eligible age as per state requirement
  • All free bets expire in 7 days.
  • Free bets in five $10 Free Bet Tokens are distributed within 72 hours of your bet settling.

Betting at SI Sportsbook

Even though this online sports wagering platform  is technically a brand new sportsbook, SI Sportsbook is hardly newbies to the world of sports and betting. Plus, the platform is basically a redesign of the previous (also impressive) 888sport platform.

All of this means SI Sportsbook is no slouch in the betting department, with lots of different ways to play

Odds Pricing

Most sportsbooks offer standard odds of -110 on 50/50 events. The extra -10 is called the “vig” or “juice” and is what they charge in order to take your bets.

We've found SI Sportsbook's standard odds to range anywhere from -111 to -115 depending on the sport. This means that you have to win a higher proportion of your bets in order to turn a profit. The biggest drawback of SI Sportsbook is that it often has worse odds than competitors.

It's worth noting that SI Sportsbook's odds vary quite drastically from sport to sport. So, this may not be an issue for you depending on which sports you like to bet on. Either way, we recommend using SI Sportsbook along with at least one other Colorado sportsbook so you can shop around for the best odds.

Betting Markets

New sportsbooks sometimes launch with a limited set of features, like accepting only one or two banking methods or only betting on the most popular sports. SI Sportsbook, however, offers a broad range of online sports betting options that you can choose from. 

Here are some of the betting options available at SI Sportsbook:

Available Types of Bets
Point SpreadsSpread betting is a bet on the margin of victory in a game.
MoneylinesMoneyline betting is when you pick the winner of the game or event
First Half & Second Half BetsHalves let a bettor treat the first half and the second half as separate matches. Downloading the app can help you do this with ease.
TotalsA total, also known as an over/under, is a bet on the number of points both teams will combine to score in a game
Player Prop BetsA prop bet, short for a proposition, wager that is not directly tied to the final score or outcome.
FuturesFuture bets are a bet on an event that will be decided in the future (e.g. end-of-season results).
ParlaysCombining any series of bets for increased odds where all the bets have to win to be deemed a winner
TeaserA parlay where the lines are moved up or down for increased or decreased odds
Round RobinParlays that are split into several smaller parlays mixing and matching all the legs.
Live in-gameBetting on the game after it already started with constantly updating odds
Bet BuilderSimilar to a same-game parlay, you can put together markets in the same game to build your own parlay

All the top US sports leagues are covered in SI Sportsbook, as well as lots of more niche sports and competitions from Europe and around the world. It’s common to see minor changes in available sports over time, but below is the list of sports you can bet on SI Sportsbooks.

Available Types of Sports
Aussie Rules FootballFootball (NFL/NCAA)SoccerTennis
Baseball (MLB/NCAA/other)Golf (PGA)Table TennisVolleyball
Basketball (NBA/NCAA/other)HandballRugbyeSports
BoxingHockey (NHL/other)CyclingMotor Sports
CricketMMA (UFC/Bellator)Dartsand more…

Live Betting

SI Sportsbook offers live betting on most sports including soccer, football, baseball, basketball, hockey, and more. You typically also have the option to cash out of your bets while games are still going on.

While basic, the SI Sportsbook live betting section is user-friendly. The live section features all of the events available at any time and groups them by sport for easy access. There's also a full schedule of upcoming live events. The downside stems from a barebones display that lacks stats.

Live Streaming

As of now, SI Sportsbook does not offer live streaming of games, unlike some other online sportsbooks.

Cash Out Function

The cash-out feature from SI Sportsbook applies to select matches, allowing bettors to secure a portion of their winnings or cut their losses. A cash symbol designates markets that support this feature. After placing the wager, go to the 'My Bets' section to view the available matches and the cash out value.

Same Game Parlay

“Same game parlays” have gained a lot of popularity over the past few years after sportsbooks like FanDuel started offering them. With same game parlays, you can combine sides (spread and moneyline bets), totals, and prop bets from the same game in a single parlay.

Fortunately, SI Sportsbook DOES offer same game parlays. The functionality is called “BetBuilder”. If the game you are interested in offers same game parlays, you will see a BetBuilder tab after clicking into it.

Clicking the BetBuilder button will bring up a box that allows you to add markets to your same game parlay.

Other Notable Features

SI Sports uses proprietary software developed by 888 Sport. It keeps many of the same features and styling elements of the European 888 sportsbook, such as these ones.


Access the most popular markets via the BetFeed tab, conveniently located within the main menu. Here, you gain insight into which bets fellow community members are backing, and you can customize the display based on your preferred sports and bet types.

Odds Boosts

SI Sportsbook's odds boosts are called SI SuperBoosts.There are typically around 3 to 10 at any one time and most are on parlays and other longer shot bets. Because of this, it's important not to blindly take every odds boost. Though the odds are boosted, the bets still don't have a great chance of hitting.

Be sure to still do your research when deciding which (if any) SI SuperBoosts to bet on.

To find SI's odds boosts, click into the Sports A-Z menu (left side on desktop or hamburger menu in top left on mobile) and scroll down to SI SuperBoosts.

Other Products by SI Sportsbook

At this time, it does not appear that SI Sportsbook offers products other than sports betting and iGaming space. In contrast to some other books that are backed by casino brands, SI Sportsbook is backed by a sports media brand.

SI Sportsbook Mobile App


Guide on what apps the operator are offering - is the more than one app and are they available in-app store and google play, etc. Breakdown the sportsbook app into the following steps: 

  • Compatibility - Android, iOS etc.
  • Speed
  • Stability
  • Design/Appearance
  • Betting user experience - How smooth is the betting process.

SI Sportsbook launched with the ability to bet on both your computer and mobile device. SI Sportsbook can be accessed through your favorite web browsers, such as Chrome, Safari, Edge, or Firefox.

However, for maximum experience, if you are betting on your mobile device, you can download the app from the Apple App Store if you are on an iOS device or directly from the website for an Android phone or tablet

The SI Sportsbook app is a solid platform, and we have analyzed all aspects of the app below:

  • Availability: The app can be downloaded to both iOS and Android devices alike. For iPhone and iPad users, simply wander on over to the App Store. For Android users you will need to venture into the Google Play Store.
  • Speed: It’s not the fastest app we’ve tested, but it did not prevent us from getting our bets in. There is some delay when first opening the sportsbook, and a bit of a delay when switching betting markets, but the only time that may be a problem is when you are live betting and time is of the essence. Generally speaking, it’s not much of a hindrance.
  • Stability: Through our testing we did not see any major crashes, but once again, there are some delays in displaying new pages.
  • Appearance: The SI Sportsbook app is not going to blow you away with its aesthetics, and actually looks a bit vintage (as vintage as a mobile app can be), which personally, this reviewer kind of likes. I guess it all comes down to preference, but the appearance of the app is neither going to get you excited, nor will it make you immediately close the app.
  • View/Layout: The layout is fairly standard from what we have seen in the industry, which is a good thing. Utilizing buttons across the top and bottom of the screen to get to your favorite markets, banking, account info, and more. We would like to see the scrolling promotions across the top of the screen maybe shrink down a bit, but that may just be splitting hairs.
  • Betslip Building: This is one of the best features of the mobile app, as the betslip stays hidden until beckoned. This means you can add as many bets you want, whether is a single spread bet or a 12 leg parlay, the bets will be added, but stay minimized until you click to open it. Once opened, you will see a plethora of betting options such as teasers, single bets, parlays, and a variety of round-robin parlays.
  • Live Betting: The live betting selection is great, but with the speed of the app, you may have some trouble getting them in on time. This doesn’t mean that it’s not possible to bet a live spread, but betting on individual drives, points, or plays may see its share of problems.
