Undeniably one of the best sportsbooks in the U.S., DraftKings delivers what we consider to be the top Colorado sportsbook promo. The bet $5, get $200 in bonus bets reward is straightforward, contains no restrictions, and — best of all — delivers guaranteed funds.

Who is the DraftKings promo best for?

The DraftKings Sportsbook CO promo is ideal for new bettors. The minimum investment of a $5 deposit and wager isn't steep, and simply betting on any market of your choosing unlocks a guaranteed $200 in bonus bets to use on future wagers.

Alternatively, you can nab a $1,000 deposit bonus on top of the $200 promo. However, keep in mind that this offer is best suited to high-rollers since you must put down $5,000 and meet wagering requirements to earn the maximum $1,000 reward.

• Sign up with DraftKings CO if you are 21 or older. No DraftKings promo code is necessary.

What users are saying about DraftKings

“The interface and betting options are far superior to other betting apps.” — Brad Hodgin, Google Play store reviewer

"I have been using DraftKings as a sportsbook/casino for exactly a year since they launched in my state. Overall, I think it is one of the best books because its app has a very clean and intuitive UI, and its customer service is unmatched." — Reddit user

“The app itself is relatively slow. The profit boosts are nice and unlike anything I’ve ever seen on any other app or site. So that’s a plus. The lag on placing bets is a bit annoying, but it’s understandable. The UI is nice, and the social hub is a huge plus and extremely underrated.” — Johan, App Store reviewer

What users are saying about FanDuel

“The UI of the app is incredibly smooth and responsive. The best of any sportsbook app I've used.” — Andrew Withers, Google Play store reviewer

"I just found out my girlfriend had her sign-up bonus on FanDuel, and I didn’t realize that if you referred a friend, you could both get an additional credit. Well, she did sign, but she was so excited about signing up that we missed it.” — Evert, App Store reviewer

"I use FanDuel mostly for sports betting. Its software, layout, and how it gives you real-time stats are all reasons why I use it over DraftKings." — App Store reviewer

What users are saying about bet365

"I really like using bet365, as it offers a wide variety of sports to bet on and has an abundant prop menu. One thing I really like with NBA props is the ‘milestones’ that allow you to bet beyond the Las Vegas line on various stats." — Francis, Google Play store reviewer

"The gold standard and they simply can’t be beaten. Any bettor with experience knows that bet365 is light years ahead of the competition in terms of, well, everything, like betting limits, customer service, and user interface." — Reddit reviewer

"The bet365 app is very easy to navigate, and placing bets is as easy as can be. It offers tons of wager options and is extremely easy to use any bet credits you have, but it’s just such a visually boring app.” — Timbo, App Store reviewer

Who is the BetMGM promo best for?

Oddspedia opinion

When reviewing Colorado sportsbook promos, we zero in on some specific criteria to uncover the top options. Here are a few of those key factors:

Guaranteed funds

Not all bonuses give you guaranteed funds. For example, bet insurance promos do not, despite having typically high maximum value. Bet-and-get rewards, on the other hand, often will deliver a guaranteed bonus at the cost of a lower maximum value. We will always prefer the promos that deliver a sure thing. 

Playthrough requirements

Playthrough requirements are minimum betting requirements that you have to hit before you can withdraw your bonus winnings. We look for bonuses with low playthrough requirements.

Ongoing bonuses

Welcome bonuses are just one form of CO sportsbook promos. The best sportsbooks also have loads of existing customer promotions and ongoing offers for you to claim once you start betting.

Current Colorado sports betting law — which came courtesy of House Bill 19-1327 - permits the state's 33 licensed casinos to earn a primary license, allowing them to provide sports betting at their respective retail locations via an online partner. For now, 14 virtual options are available to CO bettors, all of which are among the top Super Bowl betting sites in the country.

Although the best Colorado sportsbook promos we just went through are all welcome offers, there are plenty of other types of promotions to be aware of. Here are several of the most popular: 

Welcome offers

While only available to new users, welcome offers are usually the most generous promos you’ll find at Colorado sportsbooks. These bonuses come in many forms, including bet-and-get offers, first bet insurance rewards, and more. 

Referral offers

If you have a friend interested in sports betting, then claiming a sportsbook referral bonus can reward you both. You’ll get a special code or sign-up link that you can share. Once your friend registers with it, you each will typically receive some type of bonus. 

Bet-and-get offers

Bet-and-get offers provide significant value for a small investment. Typically, they promise guaranteed funds as well, though some versions require you to win your first bet. These promos are common as welcome bonuses, but they are also offered regularly as existing customer promos around big sporting events. 

Bet insurance offers

Unlocking bet insurance offers requires you to lose your first bet. Due to their riskier nature, their maximum value is generally quite high. Like bet-and-get rewards, these Colorado sports betting promos are often presented as welcome bonuses.

Deposit matches

Deposit matches give you what you are willing to put in. These promos provide bonus bets equal to a percentage of your deposit. While often available for your first deposit, many sportsbooks also offer reload bonuses for returning customers.

Odds boosts

Odds boosts are bets with higher odds than usual, thanks to an ongoing promotion. These wagers — which can be for NFL odds, NBA odds, MLB odds, NHL odds, or other sports or leagues — are normally long-shots like multi-leg single-game parlays, but they can be high-value if you are smart about which ones you back.

Profit boosts

Profit boost promotions are nearly the same as odds boosts, except you have input. Instead of being limited to the options presented to you by the sportsbook, receiving a profit boost enables you to choose which bet you want to boost. 

Ultimately, deciding which Colorado sportsbook bonuses to claim is up to you. That said, there are still some considerations worth keeping in mind as you scour the options. Here's what we look at when discerning what makes a quality CO sportsbook promo:

Worthwhile bonus amount

A Colorado sports betting bonus should be valuable. At a minimum, it should be enough to make signing up worth it. However, the best ones give you more than that while still featuring accessible terms and conditions.

Low deposit requirement

Ideally, it would be nice to get a reward just for signing up, but no-deposit bonuses are not common. Instead, you’ll usually have to fund your account to claim a sportsbook bonus. The best give you a lot for a relatively small deposit.

No restrictive terms and conditions

Few things can devalue a bonus, but high playthrough requirements are one of them. If you have to wager $1,000 to claim winnings from a $100 bonus, is it really worth it? Look for CO sportsbook promos with 1x playthrough requirements or similar.

Eligible for numerous payment methods

Some Colorado sports betting bonuses limit the payment methods you can use to make your deposits. The best bonuses don’t have these kinds of restrictions, allowing you to use e-wallets like PayPal, for example.

Reasonable expiry periods

Bonus bets do not last forever, nor do bonus offers. When we rate bonuses, we look for ones that give you plenty of time to claim them once you create your account and meet any wagering requirements.

Claiming Colorado sportsbook promos is straightforward. All you need to do is create a new account, deposit some money, and place your first bet. To make this process as simple as possible for you, here’s a clear step-by-step guide:

1. Pick one of the available CO sportsbooks

Assess your own betting preferences and apply the criteria explained above to pick the best Colorado sportsbook for you. Then, download the app or go to the official sportsbook website. 

2. Register for an account

Once you open the app or the mobile/desktop site, click the “Sign Up” or “Join Now” button and fill out the sportsbook sign-up form. Typically, all you will need here is your name, email, address, date of birth, and Social Security Number. 

3. Claim your bonus

On the sign-up form, you will also likely see a place to enter any Colorado sports betting promo codes you have. There could also be a box that you must check to claim the bonus offer. Make sure to go through the sign-up process carefully to avoid missing out. 

4. Deposit funds

Go to the cashier section, select “Deposit,” pick your preferred payment method, and finalize your first deposit. If you can’t find the section, check your account page or click your balance amount on the homepage.  

5. Start betting

You are now ready to place your first bet. Ensure you wager enough to satisfy your Colorado sportsbook bonus terms and conditions. 

Despite there being 14 legal sportsbooks in Colorado, a large portion of sports bettors will pick just one and stick with it. While this is fine, making the most out of your sports wagering experience requires registering with as many Colorado sportsbooks as possible.

By creating several accounts, you can claim multiple CO sportsbook promos, enabling you to get the most out of your deposits. Additionally, line shopping becomes much easier since you'll be able to bounce between your numerous accounts quickly. We have you covered with lists of the country's best football betting sites, NBA betting sites, MLB betting sites, NHL betting sites and golf betting sites to help you find the best prices per sport. If you're an auto racing fan, be sure to check out our guides to the best NASCAR betting sites and F1 betting sites.

Before claiming any sportsbook bonus, you should look at the terms and conditions. That way, you'll know if the offer is worthwhile or overly restrictive. Here are some of the common terms you should familiarize yourself with: 

Wagering requirements

Playthrough requirements, also called wagering or rollover requirements, refer to how many times you’ll need to wager your sportsbook bonus before you can withdraw winnings earned via bonus bets. The lower the playthrough requirement, the better.

Minimum deposit

Some sportsbooks will give you a no-deposit bonus just for signing up. However, most require you to deposit a minimum amount. Generally, you’ll need to fund your account with at least $10 or more to claim your Colorado sportsbook promo.

Minimum odds

Many sportsbooks attach a minimum odds requirement to their bonus bets. Basically, this is to stop you from backing huge favorites and earning easy money. In some cases, there is also a minimum odds requirement connected to your initial qualifying bet.
