Since online casinos are not licensed in Colorado and their status remains somewhat complex, this website will focus on providing information about sweepstakes. We will also continuously update the site with the latest news and developments regarding online casinos in Colorado to ensure that you always have access to current and relevant information.


Yes, gambling is legal in Colorado, but it is subject to certain restrictions and regulations.

In addition to sports betting, which was recently legalized in late 2019, Colorado also allows limited forms of casino gambling in three historic mining towns: Black Hawk, Central City, and Cripple Creek. There are over 30 casinos in these towns, all of them offering popular casino games such as slot machines, table games, poker rooms, etc.

While casino gambling is restricted to these specific locations, there are also two casino-resorts run by Native American tribes in the towns of Ignacio and Towaoc.

Furthermore, Colorado has a state lottery and permits pari-mutuel betting on horse and greyhound racing at licensed racetracks. However, other forms of gambling, such as commercial casinos outside the designated areas and online casino gambling, remain illegal in Colorado.

While there is no specific date we expect online casinos to become legal in Colorado, discussions and debates surrounding their potential legalization have been ongoing. With the success of Proposition DD in November 2019, which legalized sports betting both in-person and online, there has been increased interest in expanding gambling options to bring more tax revenue to the state.

And while a lot of people may believe so, the introduction of sports betting a few years ago does not guarantee the arrival of online casinos in the state. It does remain a possibility for the future, but the current stance suggests that Colorado may not see online casinos in the near term. 

However, the landscape could change, especially with other states jumping to legalize online casinos in the following years, which may influence Colorado’s decisions in the long run.

Ultimately, any decision to legalize online casinos would require legislative action or a statewide ballot initiative. Until then, Colorado residents and visitors can enjoy the existing gambling options available in the state, including sports betting, state lottery, and limited casino gaming at designated locations.


Gambling has a long and storied history in Colorado, dating back to the state’s early days as a frontier territory. In the mid-19th century, as settlers migrated westward during the Gold Rush era, gambling establishments began to spring up in mining towns and frontier settlements across Colorado. These early forms of gambling ranged from card games and dice to betting on horse races and cockfights. Despite the absence of formal regulations, gambling was a popular pastime among miners and settlers seeking entertainment and diversion from the rigors of frontier life.

As Colorado transitioned from a territory to a state in 1876, gambling continued to thrive, albeit with varying degrees of legality and regulation. In the late 19th and early 20th centuries, gambling establishments operated openly in many Colorado cities, including Denver, Central City, and Cripple Creek. However, the rise of anti-gambling sentiment and the implementation of stricter laws and regulations in the early 20th century led to the decline of legal gambling in the state.

In the latter half of the 20th century, gambling experienced a resurgence in Colorado with the legalization of limited stakes casino gambling in three historic mining towns—Black Hawk, Central City, and Cripple Creek. Subsequent ballot measures further expanded gambling options in Colorado, including the legalization of sports betting in 2019. 

Today, Colorado boasts a diverse gambling landscape that includes casinos, horse racing tracks, and a growing sports betting market, attracting visitors and generating revenue for the state.


Despite not offering residents online casinos where they could play from the comfort of their home, Colorado is home to 30+ brick-and-mortar tribal casinos in the three designated towns mentioned earlier (and two outside of them), meaning the options for gaming within the state are plenty.

Therefore, we decided to create this shortlist where we mention what we believe are the top-5 casinos in Colorado that certainly make a visit to the Centennial State worth it: 


While the state has not explicitly legalized or regulated these platforms, they also haven’t been expressly deemed illegal. 

This ambiguity allows sweepstakes and social casinos like WOW Vegas and Sweepslots to function, providing Colorado residents with a way to enjoy casino-style games online without wagering real money and, therefore, without violating any specific laws. 

Upon registration with a social casino, players are instantly granted a specific quantity of tokens and “sweeps coins,” allowing them to engage in table games and online slot machines that closely resemble their counterparts in physical casinos, but without the risk of losing any money.

If you are a Colorado resident and are looking for some social casino fun, we encourage you to check the ones we tested and recommended at the beginning of this guide. These social casinos are the best alternatives due to their vast selection of games and very generous welcome bonus and loyalty program, so you should definitely check them out! 


As long as there isn’t any money involved (meaning you play on social casinos), you could very well play any popular casino game there is online while in Colorado. The beauty of online sweepstake casinos is that people from states where online gambling is illegal can play the games that are available at real-money online casinos, and even participate for real-life prizes! 

Some of the games that Coloradans can play on social casinos are: 

  • Slots: One of the most popular and entertaining casino games there is, slots offer immersive graphics and innovative features that can keep anyone hooked for hours. Besides, slots are extremely easy to play as they simply consist of clicking the “Spin” button, making them suitable for everyone. 
  • Blackjack: Another easy-to-play casino game, blackjack consists of beating the dealer to 21 without going bust, making it another very popular option for online players. Besides, it has the highest RTP percentage of any casino game, making it a must-play. 
  • Poker: A more complex yet equally popular card game you can play online, poker is an extremely fun way to spend your time at a social casino. Whether it is Omaha, Texas hold ’em, or any other poker variant, you’ll certainly find the opportunity to play at most California Sweepstakes. 
  • Roulette: The classic game of roulette, considered the ultimate game of chance, is a popular offering at nearly every online casino in the United States, and of course, one you’ll find in every California social casino. 
  • Live dealer games: These games are played through a live stream where you are able to see a professional dealer running the game in real time. Apart from all the standard table games like blackjack, roulette and poker, the live casino lobby also consists of game shows which combine the elements of gambling games and television shows, making it a very attractive option. 


In Colorado, the legal gambling age depends on the type of gambling activity. For most forms of gambling, including casino gaming and sports betting, the minimum age requirement is 21 years old. 

However, there are some exceptions to this rule. For example, individuals who are 18 years old or older are allowed to participate in charitable gambling activities, such as bingo and raffles, as long as the proceeds are used for charitable purposes. Additionally, individuals who are 18 years old or older may also participate in horse racing betting at licensed racetracks in Colorado.


The future of online casinos in Colorado appears promising, with several factors pointing towards potential legalization and expansion of online gambling activities in the state. 

As of now, Colorado has already taken significant steps towards it by regulating online sports betting in 2019, which has demonstrated the feasibility and popularity of online gambling among Colorado residents.

Additionally, the state’s growing revenue from legal sports betting operations could incentivize lawmakers to further explore the potential benefits of legalizing other forms of online gambling, such as online casinos and poker. 

So overall, while the future of online casinos in Colorado is uncertain as the introduction of sports betting does not necessarily guarantee the arrival of online casinos, there are promising signs that legalization and expansion may be on the horizon.


The Colorado Division of Gaming is responsible for regulating and licensing sports betting operators, ensuring compliance with state laws and regulations, and protecting consumers from fraudulent or unethical practices.

And while online casinos have yet to be legalized in Colorado, the state’s existing regulatory framework for sports betting could serve as a model for potential future regulation of online casino gaming. This means that, if online casinos were to be legalized in the future, it is likely that the Colorado Division of Gaming would be tasked with overseeing licensing and regulation of them.

Unfortunately, online casinos are not legal in Colorado as of now.
