Colorado has emerged as a leader in U.S. sports betting. Since May 2020, residents can place wagers through a robust set of legal apps and sportsbooks, including BetMGM, DraftKings, FanDuel, and bet365.
Yet when it comes to online casino gaming, the state lags behind. Under Colorado law, casino-style gambling over the internet remains banned. Efforts to broaden the state’s regulated gambling market to include these games have stalled, and no clear timeline exists for change.
Colorado Legal Online Gambling
In many ways, Colorado is ahead of the curve: sports wagering is legal, regulated, and available both in retail casinos and via online platforms.
That said, on the casino side, the state is still catching up. Online casino gambling (slots, table games, live dealers) is expressly prohibited under current statutes.
There is also the lottery, horse racing, bingo, daily fantasy sports and social casinos available to Colorado bettors.

The Centennial State is an ideal destination for those gamblers who like choice when it comes to their online sports betting habits, Colorado offering an extensive range of sportsbook apps for bettors.
Sports betting went live in Colorado in May 2020, with a mixture of online and offline options now available; many of the land-based casinos in the state opening sportsbooks in partnership with some of the biggest names in sports betting, including BetRivers, BetFred, betMGM and Caesars. Along with betting, horse race gambling is available and the state lottery.
With dozens of gambling sites to choose from, there are various incentives on offer, such as free bets and matching initial account deposits. So long as you’re 21 or over, you can simply download your app of choice, register, make a deposit and start making your bets.
There are no online casino sites available to residents of Colorado. However, the Colorado online sports betting sites available include some of the industry’s biggest names. We can see established brands like BetRivers, Bet365, and Caesars Palace Casino. Most of these operators also have online casinos – at the moment, however, it is a question of waiting to see what happens next and whether casino games in Colorado will be introduced.

Colorado Online Casinos
There are currently no legal online or mobile casinos operating in the state of Colorado. While online sports betting has been fully legalized and regulated since 2020, lawmakers have not moved to allow casino-style gambling online.
In other states, discussions around legalizing online casinos are gaining traction, but in Colorado, there appears to be little appetite or legislative momentum to expand gambling laws beyond sports wagering. For now, online slots, blackjack, roulette, and poker remain off-limits.
When it comes to land-based casinos, however, Colorado’s scene is thriving. There are more than 40 casinos statewide, most located in three historic gaming towns: Black Hawk, Central City, and Cripple Creek. Each offers a mix of slots, table games, and sportsbook lounges operated by major brands like BetMGM, DraftKings, and FanDuel.
There are also two tribal casinos in the southwest region — Sky Ute Casino Resort in Ignacio and Ute Mountain Casino Hotel in Towaoc — both operating under state compacts.
A change in the Colorado casino laws removing a $100 limit on betting has led to an uptick in state casino revenue.

Online Real Money Games
As online casinos aren’t yet legal in the state, there are no online casino games in Colorado available to play. You will find that there are many different games you can look forward to playing at an online casino in Colorado, however. Casinos in other states typically range from the latest slots on diverse themes to classic table games.
Popular slots include Age of the Gods, Starburst, and Buffalo Blitz. An interesting way of playing roulette, blackjack, and other games is through live dealer versions, which may become available, law depending.
Based on the current laws in Colorado and sports betting operators already live in the state, BetMGM, Caesars are among the first casinos expected to go live in the state.
Colorado Legal Casino Apps

At the moment, the lack of regulated online casinos in Colorado means that there are no specific bonus offers for you to accept. Expect this to be something that is offered in the future, if the state agrees to let online casinos operate here.
