You can bet on sports at both retail brick and mortar shops, as well as online and via betting apps in Colorado. However, casino gamblers remain limited to land-based sites to play slots and table games.

Colorado Betting Sites & Apps in Detail

Discover the best sportsbooks and betting apps in Colorado for 2025. Our expert review covers top operators like BetMGM, Bet365, and DraftKings, offering insights into their payment options, betting markets, and mobile app quality. It’s perfect for fans of the Denver Broncos and other local teams.

Following the decision of the Supreme Court to strike down the controversial PAPSA legislation in May 2018, Colorado became the 19^th state to legalize sports betting two years later on May 1^st, 2020.

The state has since licensed and regulated 19 online sportsbooks, including some of the most recognizable and stellar brands in the US marketplace.

Our expert team has reviewed each of these operators to determine precisely what they offer CO residents in terms of payment options, available betting markets, and the quality of their mobile apps.

But where is the best place to back the Denver Broncos, the Colorado Rockies, or the Denver Nuggets? Read on to see our picks for the top five Colorado sportsbooks.

BetMGM Colorado – The Best for Available Betting Markets

BetMGM launched in Colorado in May 2020, with the site comprehensively covering more than 20 different sports categories. Interestingly, the operator also offers thousands of betting markets, with a diverse range of options reserved for Broncos, Avalanche, Nuggets, and Rockies games.

Additionally, you can target a broad selection of smaller hockey, football, baseball, and basketball leagues at BetMGM, while multi and same-game parlays are also readily available. We also like the sportsbook’s unique ‘Edit My Bet’ feature, which allows you to tweak your selections and stake values (or even add legs to existing parlays) after the wager has been confirmed.

BetMGM has also developed polished and popular apps for iOS and Android. These apps have earned average ratings of 4.8/5 and 4.4/5 across many users.

Bet365 Colorado Sportsbook – The Best for Secure Payment Methods

Bet365 is a world-renowned European gambling brand that didn’t debut in the Colorado marketplace until September 2022. However, it has wasted no time in becoming a market leader in the state, especially in terms of its tech stack and the range of secure payment options available to bettors.

More specifically, you can process transactions using trusted banking methods such as Visa debit card, PayPal, E-Check, Instant bank transfer, and wire transfer. Secure online banking is also available, while in instances where your Visa debit card and bank are eligible for ‘Visa Direct,’ your cash withdrawal should be completed either instantly or within two hours. Broadly speaking, Bet365 payouts should take no more than two working days to complete.

Of course, you can access these payment methods through the Bet365 mobile app, whether you’re an iOS or Android user. Both examples of native software are sleek and intuitively designed, while they’re rated 4.6/5 and 4.5/5 on the Apple and Google Play Stores.

BetRivers Colorado Sportsbook – The Best for Easy Registration

BetRivers is now accessible in a dozen US states (including Colorado), while it was among the first to be granted a CO license in May 2020. In addition to its stellar rewards program and status as a revered US brand, BetRivers provides one of the quickest and smoothest registration processes in the Colorado market.

While you must be located within the state’s boundaries to bet lawfully at BetRivers CO, you can open an account from anywhere in the world simply by clicking the ‘Join Now’ button in the top right-hand corner of the screen.

You can also save time by entering your email and personal information in the banner at the top. So long as the data is entered accurately and in full, the site should immediately verify your identity and open your account!

You can also create an account through the BetRivers native apps on iOS or Android. However, you should note that these apps both have disappointing average ratings of 3.1/5, meaning that it’s at a slight disadvantage when it comes to the mobile wagering experience that it offers.

DraftKings CO Sportsbook – The Best for Live Betting and Wager Types

DraftKings hit the ground running in Colorado, opening its virtual doors as soon as possible on May 1^st, 2020. Of course, the brand is best known as a daily fantasy sports betting site, but it now offers multiple ante post and live markets and some incredibly diverse wager types.

Arguably, the site sets the gold standard regarding live betting options, while its odds are fairly calculated and enhanced through daily price boosts. DraftKings is also great for customer engagement, thanks to its creative betting specials, sportsbook pools, and popular ‘pick ’em’ contests. Popular ‘same game parlays’ can also be accessed through both ante-post and in-play markets, allowing you to combine multiple player props or totals lines in a single wager.

Unsurprisingly, DraftKings CO also offers an exceptional mobile app, with the native iOS software having earned an average rating of 4.8/5 from 453k reviews. The Android app has earned a similar rating of 4.6/5, so you can access a stellar live betting experience regardless of device.

FanDuel Colorado  – The Best Mobile Betting App

FanDuel launched in Colorado alongside DraftKings on May 1^st, 2020, having emerged as one of the most successful sportsbooks since US states started to legalize betting in 2018. In fact, FanDuel has taken more handle than any other operator in the US market, while it’s arguably the only sportsbook to have produced a better mobile app t
