SI Sportsbook Colorado Promo Offers Bet $10, Get $300 Bonus

The SI Sportsbook has gone live in the state of Colorado, the book’s first market ever in the United States. Colorado is a huge sports betting market, but Sports Illustrated was attracted to the rapid growth in choosing this state.

SI Sportsbook promo codes and promotions have caught the attention of bettors right away in Colorado as it’s hard to find a better welcome offer anywhere. That’s not the only reason to sign up for an account though as this sportsbook could easily become one of the best options for Colorado sports bettors.

This review will highlight the SI Sportsbook promo codes and promotions first, but other features of the site will be introduced as well. Since this is a brand new sportsbook in Colorado, and in the United States then all of this information is going to be brand new.

If you’re interested in taking advantage of the SI Sportsbook promo codes and promotions, then you’re going to want to pay attention. Signing up for the sportsbook is obviously the first step and the registration requirements will be outlined a bit further down.

This isn’t going to be the cliff notes version of a review as we will cover everything we can think of. Get comfortable because you’re going to be here awhile.

SI Sportsbook Promo Codes

The most logical place to start this review is by looking at the SI Sportsbook promo codes and promotions. Depending on how you want to start your betting adventure with this book, you have two options:

  1. Promo code SI300
  2. Promo code SIDIV

At the time of this writing, these promo codes are readily available only to new players. The reason why we’re saying that these promo codes are options is because you can’t pick both. It’s either one unfortunately. Check out below what these promo codes will get you.

SI Sportsbook – Welcome Bonus and how to claim it

It’s always great to have options when it comes to welcome bonuses and this is where SI Sportsbook makes it very clear – they want players who stick around. Here’s how the welcome bonus offers work when you make your first deposit and use either of these promo codes:

Promo code SI300

If you use this promo code and make your first bet of at least $10 you’ll get $300 (Link: in free bets spread over six tokens worth $50 each. Winnings on free bet tokens are granted as cash (minus the $50 stake) and can be withdrawn at any time as long as the amount is within the sportbook’s policy.

Promo code SIDIV

This promo code is better suited if you plan to continue with this bookie. If you make your first bet of $20 or more you’ll get a $10 free bet every Saturday morning for 18 weeks! That’s some pretty good dividends right there.

Then there’s a third option which doesn’t require a promo code. Simply bet $10 or more on your first bet at odds of -200 or greater and you’ll receive a $50 free bet token when your bet’s settled – win or lose!

Just make sure you read the terms and conditions carefully before you accept either one of these offers, but we can promise you that there are no bad surprises hidden in the fine print.

Which SI Sportsbook Bonus is Best for me

We wouldn’t dream of telling you which bonus at SI Sportsbook is best for you, only you will know that. But we CAN help you figure it out. Like we mentioned already, the ladies and gents behind this sportsbook obviously look for valued players who plan to stay.

If you fall into that category, then it’s pretty clear which one you should pick. Beyond the three different welcome bonuses, there are plenty of great reasons to stick with this sports betting site and we’ll get into it right after the pros and cons – the sportsbook promotions.

SI Sportsbook Pros & Cons


  • Three choices of welcome bonus
  • Long list of sports offered
  • Plenty of exciting promotions
  • Great Mobile App


  • Not a nationally recognized brand
  • No match deposit bonus offered

SI Sportsbook Promotions

You don’t have to sink a penny into a single bet before you can take part in a promotion at this betting site and win a cool 10 grand. YES! A one followed by four zeros just for you without risking a dime.

The promotion is called Perfect 10 and all you have to do is pick 10 outcomes correctly on the games suggested. If you get them all right and you’re the only one with a perfect score of 10 you get to keep the $10,000 all to yourself!

BUT even if you don’t get them all right, for every one that you DO get dead on, you will get a $1 free bet token. At least the first two times you participate. Further participation will require that you wager at least $25 during the week or you won’t get the $1 free bet tokens for your right answers.

We’re sure that you’ve heard of parlay bets before. It’s when you bet on two or more outcomes on a single bet slip to increase the potential payout if you win. Well, winning on parlays is heavily endorsed at SI Sportsbook.

Every weekend from Friday to Sunday there’s a promotion called Three & Win. It means that you can win a $20 free bet token each weekend you win on a parlay bet with three or more legs. Basically, when you win, you really win!

Another weekend promotion is the NFL Bet Builder. If you can’t decide which games to include in your parlay, let SI Sportsbook’s NFL BetBuilder tool create a unique parlay for you. Lay a bet of $25 on that parlay and if it wins you get a $5 free bet token even if your bet loses. Can’t see anything wrong with that consolation price.

THEN there’s the $20 free bet token every week you bet $100 or more on NBA and NHL games. But this will only last until New Year’s so you better hurry up for this one..

SI Sportsbook Special Offers

You’re more than welcome to rummage through the SI Sportsbook for special offers every day. There are daily bet boosts plus plenty of unique markets to bet on. If you went on a rant last night about how the Broncos, Nuggets and Avalanche are all sure to win, but the +150 parlay isn’t exactly dripping with potential winnings.

That’s when you should head over to the special offers page to see if your parlay has been boosted. If it’s the case, just bet on it! There’s never a dull moment at SI Sportsbook! The phrase, “Too good to be true,” doesn’t apply here.

In Which States Does SI Sportsbook Operate

It’s already been mentioned in this review that the SI Sportsbook is currently only available for betting in the state of Colorado. That should make bettors in the Centennial State feel pretty special, but that feeling isn’t going to last long.

SI Sportsbook has a partnership with 888Sport and that’s going to give it access to a number of other markets as well. It’s unclear how quickly SI Sportsbook will be able to move into other states, but the success of its Colorado offering will likely set the tone.

The company has already announced that Indiana, Iowa, and New Jersey will be the next three states to see the sportsbook. Sports bettors in those states will be able to enjoy the terrific SI Sportsbook prom  o codes and promotions soon as well.

So, how exactly do you go about signing up for an account at SI Sportsbook in Colorado?

SI Sportsbook Registration Requirements

It’s pretty clear that SI Sportsbook would love to open up registration to every single person in Colorado, but there are some laws that have to be followed. The most important law is that anyone wanting to bet on sports has to be at least 21 years of age.

There’s also a select group of people that cannot bet on sports in Colorado and that’s anyone that can influence the outcome of a sporting event. This includes coaches, athletes, officials, or other game day personnel.

The rest of the people in Colorado are able to sign up for an account at SI Sportsbook and that includes visitors. There’s no law that says this is only open to residents of the state, even though SI Sportsbook will ask for your physical address.

The entire signup process can be completed in a matter of minutes, and then you can take a look at the SI Sportsbook promo codes and promotions. You’ll have to provide SI Sportsbook with some personal information, but you don’t have to worry about your identity being stolen.

Here is the initial information that you must provide SI Sportsbook when creating a new account:

  • Full legal name
  • Physical Address
  • Date of Birth
  • Email Address
  • Phone Number
  • Last Four Digits of SSN

After all of that information is entered then SI Sportsbook will do a quick check to verify your identity. This will allow you to take the next step in the registration process which is creating a username and password for your account.

This is where things get a bit tricky because remembering a password is sometimes as difficult as climbing Mount Everest. You’ll want to write this information down somewhere safe so you don’t have any trouble logging in to your account.

SI Sportsbook Languages, Currencies and Odds Formats

There isn’t a ton of information available yet surrounding the SI Sportsbook regarding different languages, currencies, or odds formats. The default language is obviously English but the mobile app for Apple will come in different languages.

The U.S. dollar is the preferred currency at SI Sportsbook, and your first step will be reaching out to the customer support team if you’re wanting to change that option. One form of currency that cannot be used at SI Sportsbook is cryptocurrency.

There are three main types of odds formats in the U.S. sports betting industry, and American odds are what is used mostly here in this country. Americans like to keep things pretty simple, and this odds format does just that.

You can toggle the odds to either fractional or decimal if you prefer, but your friends might think you’re showing off a bit if you do that. It’s best though to use the odds format that you prefer and deal with some heckling from your friends.

Now it’s time to get into a couple of sections that are important to all sports bettors looking to use SI Sportsbook.

SI Sportsbook – Sports Coverage

Even though SI Sportsbook is one of the newest options in Colorado, you won’t be able to tell by looking at its sports coverage. There’s a long and extensive list available, and both American and international options are featured.

If you’re like the majority of sports bettors then you’re probably focused on football over anything else. That’s perfectly fine, but you can go ahead and expand your horizons a bit as well.

It’s easier to simply provide you with a list of sports offered at SI Sportsbook, even though this list won’t be complete:

  • Badminton
  • Baseball
  • Basketball
  • Boxing
  • Cricket
  • Curling
  • Cycling
  • Darts
  • Esports
  • Football
  • Golf
  • Hockey
  • MMA
  • Motorsports
  • Rugby
  • Soccer
  • Swimming
  • Table Tennis
  • Tennis
  • Track and Field
  • Volleyball

Now that you know what sports you’re going to see at SI Sportsbook it’s time to take a look at the different ways you can bet on each sport.

SI Sportsbook – Betting Markets

When it comes to SI Sportsbook promo codes and promotions, the sportsbook is clearly trying to gain an edge on the competition. With betting markets, SI Sportsbook is simply doing what it takes to keep up with the other top sportsbooks in the industry.

There are a number of different betting markets offered at SI Sportsbook and most will be offered on all of the sports listed above. Some betting markets are only reserved for different sports, but you can find that information before you place a wager.

This is an area that SI Sportsbook can look to expand and grow as it starts to launch in different states as other operators are trying to create new bets all of the time. For now, you’re going to enjoy the list of betting markets if you’re a customer at SI Sportsbook:

  • Moneyline
  • Spread betting
  • Totals or Over/Under
  • Parlays
  • Teasers
  • Round Robin
  • Individual Props
  • Team Props
  • Futures
  • Live Betting

SI Sportsbook Payment Methods

Before you can even think about taking advantage of the SI Sportsbook promo codes and promotions you’re going to have to make a payment to the site. Fortunately, you’re going to find plenty of good options to complete this step, and hopefully, you’ll need to know how to make a withdrawal request as well.

All of the banking transactions at SI Sportsbook are safe and secure, and this is an area that should continue to improve as time goes on. Be sure to choose the payment method that works the best for you, and also choose one that will allow you to receive a payout in a timely manner.

Without further ado, here is how to make a deposit and withdrawal at SI Sportsbook.

How to Deposit

SI Sportsbook requires a minimum deposit of $10 regardless of which method that you choose. This is also the requirement that you’ll see listed for the SI Sportsbook promo codes and promotions.

  • ACH/Online Bank Transfer
  • Credit Card (Discover, Mastercard, Visa)
  • Play+ Card
  • PayNearMe

Unfortunately, SI Sportsbook is not yet accepting PayPal as a payment method, but that could be coming at some point. Be sure to check out the list of acceptable deposit methods anytime that you’re wishing to add some extra money to your account.

How to Withdraw

Before you even think about the SI Sportsbook promo codes and promotions, you’re probably more concerned about how you get your money if you win. That’s a common and acceptable thought because this can sometimes be a hassle.

That’s simply not the case at SI Sportsbook as you’ll be able to use the same deposit method to receive your winnings. Getting your winnings can take a matter of minutes, or at the very least should be available to you in 48 hours.

It’s a pretty sweet feeling to see money coming back to you from SI Sportsbook and feel free to share your success all over social media. Your closest friends will celebrate your victory over SI Sportsbook and it’s a great way to make your enemies jealous.

SI Sportsbook Customer Support

Any time that the words “customer support” are mentioned it’s usually a bad thing. No one enjoys talking to customer support for anything, but you’ll actually be happy with what is offered at the SI Sportsbook.

You’re going to see a long list of FAQs that the SI Sportsbook has compiled and this should always be your first step. It’s likely that you’ll find an answer to your question and you can avoid the hassle of asking someone else for help.

If you’re still stuck then you’ll want to click on the “Contact Us” button that’s provided. From there you can fill out a form and submit it to SI Sportsbook and someone will get in touch with you through email.

There isn’t a live chat option offered by SI Sportsbook at this time, but that would be a great addition to the customer support section.

SI Sportsbook Mobile App

The SI Sportsbook mobile app makes the sports betting experience much more enjoyable, especially for the younger generation that does everything on their phone. There’s a link to download the mobile app provided on the SI Sportsbook site, and you just need to choose the right option for your operating system.

All of the SI Sportsbook promo codes and promotions can be taken advantage of on the mobile app, and the offers will all pop up when you sign into your account. You don’t have to use the SI Sportsbook mobile app, but it seems kind of silly not to.

There aren’t a ton of reviews out yet on the SI Sportsbook mobile app as it is still very new. The mobile app is extremely easy to use, and it provides a crisp and clean look.

If you’re planning on spending some serious time at the SI Sportsbook then downloading the mobile app is a must. If you don’t yet have a smartphone or other mobile device then we apologize for wasting your time with this section.

Is SI Sportsbook Legal

Yes, the SI Sportsbook is legal in the state of Colorado, but that’s the only place that you’ll see it up at this point. SI Sportsbook had to partner with the Colorado Grande Casino in Cripple Creek before it could receive a Colorado sports betting license.

Since the SI Sportsbook is legal and available in Colorado the SI Sportsbook promo codes and promotions are available to new and existing customers as well.

Does SI Sportsbook offer live streaming on sports?

SI Sportsbook is not currently offering any live streaming of sporting events in the state of Colorado. This has become a popular trend with online sportsbooks, but SI is currently focused on entering as many markets as possible before moving into that offering.

Does SI Sportsbook have an app I can download?

Yes, and it’s the best way to take advantage of the SI Sportsbook promo codes and promotions. The mobile app is available for download on both Android and iOS devices and it will allow you to place a wager from anywhere in the state. This app is simply a must have if you’re signing up for an account.

Can I bet from my mobile at SI Sportsbook?

Yes, that’s the purpose of downloading the SI Sportsbook mobile app. All of the betting options are available right there on your mobile device, and you can also register for an account or make payments through the app.

Can I register at SI Sportsbook from another state?

This answer gets a bit complicated, but the short answer is yes. You can access the SI Sportsbook from outside of the state, but you aren’t going to be able to do anything besides sign up for an account.

If you’re planning an upcoming trip to Colorado and you want to be prepared then you can create an account and wait until you get inside of the state to place a wager. Be sure to check out the SI Sportsbook promo codes and promotions before you get too far into the process.

Can I withdraw from SI Sportsbook after I leave the state?

The SI Sportsbook isn’t going to let you make any wagers if you’re outside of Colorado, but that doesn’t apply to banking. If you have money in your SI Sportsbook then you’re able to make a withdrawal from outside of the state.

What do I do if I have trouble depositing on SI Sportsbook?

Your step if you’re having trouble making a deposit is to try a different option if there’s one that might work for you. That could save you some trouble, and it will allow you to get money onto your account.

If the problem still persists then you’ll have to reach out to the SI Sportsbook customer support team to get some answers. There’s a “Contact Us” section on the mobile app or online site and someone from the customer support team will get back to you with an answer in a reasonable amount of time.
