Is online gambling legal in Colorado?

Colorado is one of the most relaxed states in America regarding games of chance, and its regulations support almost every form of gambling.

The online gambling industry in Colorado has garnered long-term support because of the waning economy in the state’s mountain towns. Brick-and-mortar casinos were first built in Cripple Creek, Central City, and Black Hawk.

Originally, Colorado was a limited gaming state that wouldn’t allow bets over $100; however, those laws have been overturned in recent years. Casino players must be at least 21 years old, and the state holds retail casinos to a 20% tax.

Many of these brick-and-mortar casinos are home to retail sportsbooks. There are several online sports betting operators as well; however, there are no locally-regulated providers that offer other forms of real money online gambling.

If you’d like to play online slots or table games, you will have to turn to one of the top-rated offshore casino sites.

Due to its no-ban policy and high wagering limits, BookMaker is renowned for housing some of America’s high-rollers, sharps, and professional bettors.

Online Sports Gambling in Colorado 

When discussing online sportsbooks, Colorado is one of the top providers in the United States, as the sheer choice of operators is more extensive than most competing states. And with more than 30 casinos allowed to open physical sportsbooks, brand new online sports betting sites are regularly opening. As of 2024, over 24 online sportsbook operators are working out of Colorado.  

Offshore Gambling Colorado

Despite Colorado being one of the most liberal states regarding online gambling, there isn’t room for every sportsbook operator to do business within state borders. This is highlighted by the fact that local casinos are strictly based in three towns (Black Hawk, Central City, and Cripple Creek). That said, although they aren’t officially numbered as CO online gambling sites, the offshore operators providing Colorado locals with the opportunity to wager online are some of the best in North America. 

The grey area that most offshore gambling site customers in the United States take advantage of gives them an alternative to their current gambling site options. These offshore operators present various positives that locally licensed sportsbooks and casinos do not. One of the main advantages is the U.S. online gambling site tax laws, which put a hold on operators that translates to lower-priced odds and lower bonuses. However, the offshore operators provide some of the most competitive prices in the U.S., as well as significantly higher bonuses and more regular promotions. 

However, offshore sites aren’t always the most reputable and trustworthy. So, if you’re looking for the best Colorado online gambling sites that are 100% trusted, follow the recommendations from our expert team in this guide. 

History of Gambling Sites in Colorado

November 2020: Colorado voters approve Proposition DD, legalizing sports betting and allowing for in-person and online betting on professional, collegiate, motor and Olympic sports.
July 2019: House Bill 19-1327 is signed into law, legalizing in-person sports betting in Colorado’s casinos.
November 2014: Colorado voters reject Amendment 68, which would have allowed for limited casino gambling at horse racetracks.
2012: A proposal to expand gambling to allow for a casino at Arapahoe Park horse track fails to make the ballot.
2003: A proposal to allow for slot machines at racetracks fails to pass the Colorado Legislature.
1999: A proposal to allow for video lottery terminals at racetracks fails to pass the Colorado Legislature.

Payments at an Online Gambling Site in Colorado  

One of the key features many online gamblers look for in a top-rated site is the variety of banking options they offer customers. Providing an array of payment methods and withdrawal options makes online gaming and wagering much easier. 

Advantages of Online Gambling Colorado Sites 

There’s no denying that Colorado residents are spoilt for choice regarding online gambling. However, players from the Centennial State regularly opt to do business with a top-ranked offshore online gambling site as the options in-state are limited to the casinos and physical sportsbooks operating from the small towns. 

Offshore gambling sites provide Colorado residents with the best alternative and provide multiple reasons such as bonuses, privacy, and convenience – perks that land-based casinos simply cannot offer. You aren’t required to leave your home with an online gambling site, your privacy is well protected from the public, and a physical casino or sportsbook would never offer the bonuses available with online operators. 

Colorado Gambling Industry Conclusion   

We hope our guide has pointed you in the direction you were hoping for while keeping you up-to-date with information most establishments refuse to discuss. Colorado gamblers have multiple gambling options, which can often lead to feeling overwhelmed. The purpose of this guide was to break down your options and assist your decision-making, and if you’ve made it this far, we believe that you’ll know what the best online gambling sites in Colorado are. Use this helpful knowledge, and you’ll unquestionably find some of the best online gambling sites in Colorado and North America.
