Yes, Colorado permits various forms of regulated gambling overseen by the Colorado Division of Gaming (CDG). This includes online sports betting, daily fantasy sports (DFS), land-based casinos, horse racing, state lottery, and charitable/social gambling. Age restrictions apply, with DFS requiring participants to be 18 or older and other forms requiring a minimum age of 21. While online casino games are not yet legalized in Colorado, the online casinos we recommend at Best US Casinos are available in the Centennial State and can be licensed and regulated offshore. 

Colorado State Gambling Laws and Regulations 

In Colorado, gambling laws are regulated by two entities, both of which fall under the Colorado Department of Revenue: The Colorado Limited Gaming Control Commission (CLGCC) serves as the primary regulatory body for all legal gaming activities in the state, and the Colorado Division of Gaming (CDG), who assists the CLGCC in regulating gaming activities.  Here are some of the laws and regulations governing gambling in Colorado that fall under the CLGCC and the CDG:

  • The Colorado Limited Gaming Act: Enacted in 1990, the Limited Gaming Act and its series of amendments (some of which are listed below) legalize and regulate limited-stakes land-based casino gambling in three designated Colorado towns: Central City, Black Hawk, and Cripple Creek.
  • The Colorado Limited Gaming Act Amendment 50: Raises the maximum single bet limit for land-based commercial casinos from $5 to $100, expands game offerings to include roulette and craps, and makes it legal for land-based commercial casinos to be open 24/7.
  • The Colorado Limited Gaming Act — Amendment 77: Allows voters in the three designated gambling towns (Black Hawk, Central City, and Cripple Creek) to vote on increasing or removing the current bet limit of $100 on any game under the Colorado Limited Gaming Act and approve new casino games. After this Amendment, voters in all three towns approved a ballot measure to remove the betting limit.
  • House Bill 19-1327: On May 14, 2019, the Colorado legislature passed a law that allows them to legalize online and retail sports betting. However, the law is contingent on voter approval through a constitutional amendment.
  • Proposition DD: This constitutional amendment passes in November 2019, legalizing online and retail sports betting, and leading to the launch of legal online and retail sports betting in Colorado on May 1, 2020, regulated by the Colorado Limited Gaming Control Commission and the Colorado Division of Gaming.
  • Colorado Revised Statutes — Title 12, Article 40: The primary law regulating horse racing in Colorado, including pari-mutuel betting on horse racing and revenue sharing with the State.
  • Sunset Regulation of Fantasy Sports Bill: Also known as House Bill 20-1286, this Bill Legalizes and regulates Fantasy Sports operators offering fantasy sports contests for money or prizes in Colorado.
  • House Bill 1404: Passed in June 2016, defines DFS and establishes a regulatory framework for daily fantasy sports (DFS) operators within the state.
  • Article XVII, Section 2 of the Colorado Constitution: This amendment, approved by voters in 1992, established the Colorado State Lottery and mandated that net proceeds be used for outdoor recreation, wildlife conservation, open space preservation, and parks. The Colorado Division of Gaming (CDG) oversees the lottery and issues regulations further interpreting and implementing this Amendment to the Colorado Constitution.
  • House Bill 23-1041: This law prohibits wagering on any greyhound race conducted at and simulcast from a track outside of Colorado.
  • Indian Gaming Regulatory Act (IGRA): This federal law was passed in 1988 and governs tribal gaming activities, including classifying three classes of gaming that pertain to tribal casinos. All tribal casinos in Colorado operate as Class III gaming facilities.
  • Class III Gaming (IGRA): Includes a broad range of casino-style games and activities, such as slot machines, table games (blackjack, poker, etc.) and certain types of lotteries. Class III gaming requires a gaming compact between the tribe and the state, outlining the terms and conditions under which these activities can be conducted.
  • Tribal-State Gaming Compacts:  The State of Colorado has entered compacts with two tribal nations in Southwest Colorado that establish a framework for tribal gaming. These compacts allow these two tribal nations to operate casinos on their reservations: Southern Ute and Colorado 1995 Compact and Ute Mountain and Colorado 1995 Compact.

These laws collectively form the regulatory framework for legal gambling in Colorado. You should refer to official government sources such as the Colorado Division of Gaming for the most accurate and up-to-date information.

Are Online Casinos Available in Colorado? 

Yes. Players in Colorado can gamble at offshore online casinos while state-regulated options remain limited. Colorado has yet to pass legislation or amend the state constitution to allow online gambling to be based in the state. All the sites for Coloradans you’ll find on Best US Casinos are offshore internationally licensed sites. DuckyLuck is our recommendation for the best casino available in Colorado for overall well-rounded gambling experience.

Is Online Poker Available in Colorado? 

Since online poker falls within the scope of online gambling, online poker is only available in Colorado via offshore sites. At Best US Casinos, the online poker sites we recommend still provide excellent poker experiences to Colorado players — including video poker, live tournaments, Sit & Go, and much more.  You can also find Omaha and Texas Hold’em — the two most popular poker variations at Colorado cardrooms.

Are Online Sportsbooks Available in Colorado? 

Yes, online sportsbooks are available in Colorado and fall into two categories: regulated and offshore. The Colorado Division of Gaming (CDG) and the Colorado Limited Gaming Control Commission oversee online sportsbooks in Colorado. These state-based sportsbooks have limited bonuses and betting options, so we recommend offshore online betting sites. The offshore online international sites recommended by Best US Casinos are available in the Centennial State and offer wagers on almost any contest. There are currently no state-based restrictions for betting on in-state college teams, but it’s worth mentioning that college player prop bets are prohibited across all sports in Colorado, which means you can’t place your bets on individual player statistics.   With that said, you can cheer for your favorite teams, like the CSU Rams, while placing your bets from the comfort of your home.

Are Online Racebooks Available in Colorado? 

Despite horse racebooks being one of the legal forms of retail gambling in Colorado, online racebooks remain an option only available through offshore sites.  There have yet to be any ballot initiatives targeting the absence of online racebooks within Colorado’s legalized online sports betting framework, but the issue may gain further traction.  Conveniently, most online offshore sportsbooks perform double duty by hosting racebooks as well — including those we recommend for Coloradan bettors.

Land-Based Gambling in Colorado

Colorado has five legal types of land-based gambling: tribal Casinos, state-regulated commercial casinos in designated towns, pari-mutuel wagering facilities, horse racetracks, and in-person sports betting facilities.

Tribal Casinos in Colorado

Colorado is one of 30 US states with legal Native American casinos. They were legalized by the Indian Gaming Regulatory Act (IGRA), passed by President Ronald Reagan in 1988. There are two tribal casinos in Colorado:  The Ute Mountain Casino Hotel and the Sky Ute Casinos & Resort.   These tribal casinos are Class III Facilities. Each tribal casino has its own Tribal Gaming Commission responsible for regulating its day-to-day operations. Each of the tribal casinos in Colorado is subject to compacts between the operating tribe and the state. Every state-tribal casino is overseen by the National Indian Gaming Commission (NIGC) to ensure all tribal casinos comply with the Indian Gaming Regulatory Act (IGRA).

Horse Racetracks in Colorado 

Horse racing and pari-mutuel wagering were both legalized in Colorado in 1948 by the Colorado Gambling on Horse and Animal Races amendment.  The only live horse racing track still in operation in Colorado is Arapahoe Park.  Coloradans can still place bets on horse races happening at tracks across the country or internationally at the seven legalized off-track betting (OTB) facilities. Some casinos and sportsbooks in Black Hawk and Central city also offer simulcast horse race betting. Gamblers can place in pari-mutuel wagers, allowing betting on various aspects of horse races, including win, place, show, exactas, and trifectas.   In November 2023, the Colorado Limited Gaming Control Commission approved new rules allowing fixed-odds wagering on horse races within licensed retail sportsbooks and casinos for a 24-month period.

Listed below is the only live horse racing track in the state, followed by the most popular pari-mutuel wagering facilities currently available in Colorado:

Other ways to Gamble in Colorado

Apart from casinos and sportsbooks, Colorado has several other gambling options. These include a state lottery, charitable gambling options, social and sweepstakes casinos, and daily fantasy sports (DFS). Let’s look at these in more detail:

Colorado State Lottery

Founded in 1983, the Colorado State Lottery was founded to generate revenue for the state’s public-school system, parks, and wildlife.  You must be 18 or older to purchase a lottery ticket in Colorado. The Colorado State Lottery offers draw games like Powerball, Mega Millions, scratch-offs, and local favorites like Lotto+.  Online play is unavailable, but physical tickets offer chances at jackpots that soared past $27 million. The Largest Powerball Jackpot was 158.7 million won by a single player in 2013. 

Colorado Charitable Gambling (Bingo, Raffles, Etc.)

In Colorado, charitable gambling is governed by the Charitable Gaming Act. The Act permits qualified charitable organizations to conduct gaming activities, such as bingo and raffles, to raise funds for charitable purposes. The act allows people aged 21 and older to participate, and organizers and venues need a proper license.  There are maximum prize limits, and all proceeds generated must be allocated to charities. If you are interested in real money bingo, you can check out the options we recommend at the online offshore casinos.

Social & Sweepstakes Casinos

Social casinos and sweepstakes casinos provide an alternative way to enjoy online casino-style games in Colorado. However, these sites use tokens, chips, or virtual currency in exchange for real money, which creates a legal gray area in Colorado. This is because Colorado needs more specific legislation targeting social and sweepstakes casinos and explicit legal authorization. However, there are also no clear regulatory prohibitions against them.

The Colorado Limited Gaming Control Commission (CLCGC) oversees legal gaming activities in the state, and they have not specifically addressed social and sweepstakes casinos.

Social casinos, such as Chumba Casino and Luckyland Slots, enable players to indulge in online casino games in Colorado with virtual currency for entertainment. Sweepstakes casinos, like Global Poker and LuckyLand Slots, offer games that give players the ability to play with virtual currency and have the chance to win cash prizes through sweepstakes promotions. The legal landscape surrounding social and sweepstakes casinos is evolving, and Colorado may eventually regulate them.

Daily Fantasy Sports (DFS)

Daily Fantasy Sports (DFS) in Colorado is regulated through House Bill 20-1286, which was passed in 2020. This legislation established a licensing and oversight framework for DFS operators in the state. Only DFS platforms with valid licenses from the Colorado Division of Gaming are legally permitted to operate in the state. The legislation includes several consumer protections, such as setting the minimum age requirements at 18 years or older to participate in DFS, responsible gambling practices, and mechanisms for dispute resolution. DFS operators must pay a tax rate of 12.9% on gross revenue generated in Colorado. Colorado has an open market for DFS brands, offering players more options than some states with exclusivity agreements. Major DFS platforms such as DraftKings, FanDuel, and Underdog are all licensed and currently operating in Colorado.

Most Popular Games at Colorado Online Casinos 

With the constitutional changes to gambling laws that have eliminated Colorado’s strict betting limits, gambling revenues show Coloradans are gambling more than ever. Here’s a breakdown of the types of games popular with gamblers in Colorado:

Slot Machines

Of all the gaming machines in Colorado, it’s estimated that more than 15,000 are slot machines.  It’s no surprise that slots are so popular in the Centennial State, given that they are easy to play, offer a chance at big wins and exciting new themes are regularly introduced. In the online space, developers face little overhead in rolling out new and exciting slot games for Coloradans to enjoy.


Blackjack remains a casino classic in Colorado, celebrated for its combination of luck and strategy. According to a 2021 Visit Black Hawk survey, Colorado players strongly prefer blackjack, ranking it as the most popular game after slots. Online casinos accessible to Coloradans offer diverse versions, delivering an immersive home gaming experience. With over 20 blackjack variations, Ignition Casino stands out for providing the best live dealer blackjack experience compared to its competitors.


Dating back to 1859 during Colorado’s gold rush era, poker has deep roots, with saloons serving as poker hubs and figures like Butch Cassidy honing skills in the state. Over a century later, poker, particularly Texas Hold’em, remains highly accessible for Coloradan gamblers, offering the thrill of competition and strategic bluffing for substantial wins. Poker options are abundant in Colorado’s historic gambling towns and our recommended online casinos, making it a popular choice for Coloradans.

The game’s popularity is evident as major casinos prominently display tournament schedules, table limits, and promotions related to Texas Hold’em on their websites.

The Future of Colorado Online Gambling 

Colorado’s online gambling landscape offers limited but promising options. Sports betting reigns supreme, legalized in 2019 and thriving through licensed platforms. Online casinos, however, remain firmly off-limits, leaving players with the offshore licensed site we recommend and social casino alternatives where no real money is exchanged.

The outlook for online gambling in Colorado is shrouded in a mix of cautious optimism and political hurdles. On the one hand, the success of online sports betting and the state’s growing tourism industry hint at a potential appetite for expansion. On the other hand, a patchwork of regulations, competing interests, and vocal opposition from certain groups create a complex path forward.

Here’s a snapshot of what’s shaping the future of online gambling in Colorado:

  • Legislative limbo — Several bills aiming to legalize online casinos have been introduced but face stiff headwinds from anti-gambling groups and concerns about addiction.

  • Lobbying tug-of-war — Pro-gambling and anti-gambling groups are actively campaigning, with casinos pushing for expansion and anti-addiction advocates urging caution.

  • Tribal tensions — Native American tribes, who already operate casinos in the state, may oppose online gambling expansion, fearing competition and erosion of their revenue streams.

  • Government’s guarded stance — While not staunchly against online gambling, the state government prioritizes responsible gaming practices and seeks a balanced approach to addressing social impact concerns.

Overall, the future of online gambling in Colorado remains uncertain. While progress is possible, it likely hinges on navigating the complex web of conflicting interests and balancing economic opportunity and responsible gaming. Until then, Coloradans must settle for online sports betting and social casino options for their virtual gaming fix.
