Best Colorado sportsbook sites

Colorado has a good selection of licensed sportsbooks. Still, only a handful rank as my top choices: BetMGM, Caesars, DraftKings, FanDuel, and bet365. I selected these sportsbooks based on factors such as security, bonuses, the range of sports offered, usability, and overall betting experience. Let's take a look at what each one offers:

  • Multiple payment methods
  • Mobile applications for Android and iOS
Negative Aspects
  • Delayed responses via email
  • Review of withdrawal requests can take up to 5 days
Visit BetMGM Sport

BetMGM's welcome offer in Colorado is pretty sweet, offering up to $1,500 paid back in Bonus Bets, if you don't win, with just a $10 minimum deposit to get started. Moreover, the sportsbook provides an extensive range of sports available for betting, from major leagues such as the NFL, NBA, and NHL to soccer, golf, tennis, and more. During my review, I especially enjoyed live betting on volleyball, table tennis, and basketball games.

The height of my experience at BetMGM was the ability to stream events live. Each competition also comes loaded with betting markets, including double chance, both teams to score, total goals, goal scorers, and more.

Caesars Sportsbook – Make your first cash wager of $1 or more

Positive Aspects
  • Generous welcome offers
  • Wide range of markets
  • Live chat support
Negative Aspects
  • No esports available
Visit Caesars Sport

Caesars Sportsbook continues to lead the way in Colorado promos. With an initial cash wager of just $1, this offer can increase the potential returns on your next 20 wagers, with each boost capped at $25 per bet.

This Colorado betting site is also well known for offering profit boosts across a range of sports events. During my review, I found an NBA odds boost priced at +740, which was a pretty solid deal if you ask me. The sportsbook offers 20 sports, including popular options such as soccer, tennis, golf, basketball, and football. Live betting is fully supported, with multiple markets available on a single event.

DraftKings – Various sports and entertainment awards to bet on

Positive Aspects
  • Great mobile apps
  • Supports live streaming
  • Withdrawal takes 1 to 3 days
Negative Aspects
  • Subpar customer service
Visit DraftKings Sport

DraftKings makes an impression with its welcome promo offering $200 in Bonus Bets if your $5 wager wins. The sportsbook covers at least 18 sports, ranging from baseball, basketball, and football to boxing, golf, and other popular sports. What sets DraftKings apart is its unique range of specialty markets. During my review, I noticed that CO bettors can also place wagers on major entertainment awards, including the Academy Awards, the Golden Globes, and the Grammy Awards.

Even better, DraftKings offers a live betting experience, paired with live streaming on select sports, such as table tennis and volleyball.

FanDuel – Features the most competitive odds

Positive Aspects
  • Best in class usability
  • Available in 25+ states
  • Competitive odds and coverage
  • Top tier brand rep
Negative Aspects
  • No sportsbook VIP program
Visit FanDuel Sportsbook

FanDuel hit me as a top Colorado sports betting site due to its generous welcome promo and competitive odds. With just $5, you can receive $150 in Bonus Bets if your bet wins. The sportsbook supports over 20 sports, including Aussie Rules, baseball, football, and golf. During my review, I found live betting available across 19 competitions, including sports like tennis, racing, and cricket.

Parlays are especially popular at FanDuel, largely due to the competitive odds on offer. As an example, an NFL same-game parlay was listed at +3104, which would result in a $310.49 payout on a $10 bet if it settled successfully. It's no surprise that nearly 2,000 bettors jumped on that same SGP, showing just how competitive these odds can be.

bet365 – A sizable sportsbook welcome bonus with Golden Chips included

Positive Aspects
  • Fast, reliable mobile app performance
  • Quick deposits and fast withdrawals
  • 24/7 live chat customer support
Negative Aspects
  • Unavailable in some US states
  • Phone support hours not 24/7
Visit Bet365 Sport

The bet365 welcome bonus is quite different from what you have at many Colorado online sportsbooks. As a new bettor, placing a $5 bet gets you $150 in Bonus Bets, plus 10 Golden Chips that can be used on select live dealers.

When it comes to betting options, bet365 offers more than 20 sports, featuring major options such as boxing, soccer, football, and golf. I also appreciated seeing esports included, which added variety to the experience. Moreover, bet365 offers a bet boost feature across multiple sports, including the NBA and the NFL. During my review, I noticed an NFL market move from +2500 to +2800, meaning a $10 wager would return $290 if the bet settled successfully.

How to make the most of your experience on your selected CO sports betting site

Although the sportsbooks featured on this page offer Colorado bettors an enjoyable betting environment, approaching each site thoughtfully can help you avoid issues and take advantage of all the features available. Here's how to maximize your experience:

📄 Read the site's terms and conditions

I know, this is the boring part, but before placing your first bet, take time to read the sportsbook's terms and conditions. This will help you understand what the site expects from you and which actions may result in restrictions. During my review, I found that all the sportsbooks featured on this page require accurate, current, and complete information during the registration process. Providing incorrect or incomplete details may result in account restrictions at the sportsbook's discretion.

Also, note that terms and conditions are subject to change, so it's essential to stay updated to avoid any surprises.

🎁 Consider claiming promotions

There are numerous Colorado sportsbook promos available, and taking advantage of them can improve your experience. Start with the welcome offer, and as a regular bettor, you can consider profit boosts on your favorite sports or a referral reward for inviting friends. Always read the bonus terms and conditions before claiming any offer to ensure eligibility and avoid issues.

🛡️ Use responsible play tools

Maintaining your experience involves utilizing the responsible play tools provided by the sportsbooks. For instance, FanDuel offers options such as deposit limits, contest entry limits, maximum entry fee limits, and more. All the CO sportsbooks on this page also allow you to take a break or self-exclude if needed. Setting these controls from the start helps you maintain a safe and balanced betting experience.

🎯 Bet smartly

Placing bets without research can limit your enjoyment. Before wagering, familiarize yourself with the sports or markets you are interested in. Moreover, consider factors such as team or player form, injuries or suspensions, weather conditions, stats, and trends.

Also, avoid placing maximum bets initially; start with smaller wagers when you're still learning how the site works. This approach helps you control your betting experience and manage potential outcomes.

📞 Contact customer support

When you encounter an issue, reach out to customer support, rather than relying on third parties. One reason BetMGM, Caesars, DraftKings, FanDuel, and bet365 rank highly for me is their reliable support. For instance, bet365 offers 24/7 customer support via live chat, email, and phone. I even tested assistance on its social media pages, including Facebook and Instagram, and I received prompt responses. Using these channels ensures you receive accurate guidance and avoid unnecessary complications.
