Colorado Online Gambling

Legal online casinos, poker and sports betting in Colorado

The gateway to the West has officially opened, as Colorado sports betting debuted to residents in May 2020. Such gaming expansion provides the Centennial State with a taste of an ever-expanding industry, one that includes retail and online sports betting.

For the time being, sports betting remains the only form of regulated online gaming for the Coloradans. Already, though, the public has access to four operators with online sportsbooks and surely more to come in the near future.

Colorado sports betting

A new age dawned on the Colorado gaming world in May 2020, as the state’s first online sportsbooks made their debut.

While Coloradans do have access to a handful of brick-and-mortars, they have access to 16 betting apps:

  • FanDuel Sportsbook
  • DraftKings Sportsbook
  • Fox Bet
  • BetRivers
  • BetMonarch
  • BetMGM
  • Sky Ute Sportsbook
  • SBK Sportsbook
  • BetWildwood
  • Circa Sports
  • ELITE Sportsbook
  • theScore
  • Betfred
  • William Hill
  • PointsBet

No doubt, that group expects to welcome more competition in the coming weeks.

Online sports betting in Colorado pretty much puts a Las Vegas sportsbook in your pocket, with all kinds of single-game wagering, futures, props and live betting options available on mobile devices throughout the state.

The launch of this new market represents a great time to try sports betting. 

CO online sportsbooks will offer a variety of risk-free bets, no-deposit and matched-deposit bonuses to draw in new players.

Is online gambling legal in CO?

While there is no legal online casino gambling or online poker in the state, Colorado sports betting made its debut in May 2020.

Voters in November 2019 approved the regulation of retail and online sports betting. And six months later, on the first possible day of legalized wagering, four operators launched mobile sportsbooks.

The last time any Colorado lawmakers tried to get an online poker bill passed was in 2013. The effort quickly died even before any votes were cast.

Colorado offers legal daily fantasy sports (DFS).

It did so in 2016, with a bill allowing the state’s Division of Professions and Occupations to govern DFS activity and set license and renewal fees for operators. It also allows smaller DFS operators with less than 7,500 users to operate without a license.

Colorado voters passed Proposition DD on Nov. 5, 2019, legalizing retail and online sports betting in the state. And on the first official day of legal wagering, four online sportsbooks hit the market.

Retail sports betting is limited to licensed sportsbooks inside licensed casinos in the cities of Black HawkCentral City and Cripple Creek. However, the law also allows these casinos to apply for licenses to run statewide online and mobile sports betting, either by themselves or with outside partners.

Online lottery in Colorado

Colorado does offer online lottery sales. However, the Colorado Lottery does have a mobile app and website with information and game tools.

It is possible to purchase tickets for drawings in advance, using the state’s “Advance Play” option for PowerballMega Millions, Colorado Lotto+ and Lucky for Life tickets. However, Colorado does not offer an online or mail-in subscription service. The Advance Play feature is only available through lottery retailers.

Legal poker in Colorado

There is no online poker in Colorado. The last legislative effort to bring legal poker sites to Colorado was in 2013, and it didn’t even get to a vote.

Global Poker, using a sweepstakes model, remains to be the only legal online poker option for players in the state.

There are also six live poker rooms in Colorado, including:

  • Ameristar Casino Poker Room: Black Hawk (22 tables)
  • Golden Gates Casino Poker Parlour: Black Hawk (18 tables)
  • Isle Casino Poker Room: Black Hawk (seven tables)
  • Midnight Rose Poker Room: Cripple Creek (nine tables)
  • Sky Ute Casino Poker Room (tribal casino): Ignacio (six tables)
  • Ute Mountain Casino Poker Room (tribal casino): Towaoc (eight tables)

Bet on horse races in CO

Colorado legalized pari-mutuel wagering on horse races in Colorado in 1948. 

Colorado’s first horse racing facility, Centennial Race Track, opened in Littleton, which is outside of Denver, in 1950. It went out of business in 1983.

Pikes Peak Meadows opened in 1965, south of Denver in Colorado Springs, but it became a racecar speedway in 1993.

Finally, Arapahoe Park opened in 1992 in the Denver suburb of Aurora. Arapahoe Park remains the only live horse racing venue in Colorado. 

It offers live racing, running a mixed thoroughbred and quarter horse meet from May to August.

It also offers simulcast wagering. There are 12 off-track betting (OTB) parlors throughout the state that do the same.

Colorado once had dog racing, but it was made illegal in 2008.

Colorado also permits online horse betting.

Making bets online on horse races is legal due to a carve-out for pari-mutuel betting pools. 

Three major US-owned and operated horse betting sites and apps cover Colorado and most other states: TVGBetAmerica and TwinSpires

You can bet on races that occur outside of the state. These sites allow you to bet on tracks across the country and international races, and the special bets include the winner of the Triple Crown.

Cripple Creek, Central City and Black Hawk casinos

This section is a directory of some of the largest casinos you can gamble at in Colorado.

In 1990, Colorado voters initially approved limited-stakes gaming in Cripple Creek, Central City and Black Hawk. 

The first limited-stakes casinos launched in October 1991. The maximum bet allowed was only $5. Slots, blackjack and poker were the only games allowed and casinos had to close from 2 a.m. to 8 a.m.

In 2008, CO voters passed Amendment 50, raising the maximum bet to $100, adding craps and roulette, and allowing the casinos to stay open 24 hours, starting in July 2009.

Now, a proposal is in the works that would allow the casinos to remove the $100 betting limit altogether.

Former Cripple Creek Mayor Bruce Brown and former Colorado Senate President Bill Cadman are making a push to get Initiative 257 onto the November 2020 Colorado ballot. It would allow residents of the three casino towns to decide whether they want to remove that $100 limit and approve new games.

To get it on the ballot, they will need to submit 125,000 valid signatures to support it, representing at least 2% of the registered voters in each of Colorado’s 35 Senate districts, by August.

Initiative 257 would then need to get 50% of the vote to allow residents of Cripple Creek, Central City and Black Hawk to decide if they want to raise or eliminate the betting limits and add new types of games starting in May 2021.

According to the Colorado Limited Gaming Control Commission, the number of open and operating licensed commercial casinos and Indian casinos in the state has dipped from 42 in 2013 to 33 in 2020.

The hope is that the launch of sports betting can be a boost to the local casino economy.

Legal daily fantasy sports in Colorado

Colorado passed a law regulating the daily fantasy sports industry in 2016.

The law:

  • Puts the Colorado Division of Professions and Occupations in the Department of Regulatory Agencies in charge of overseeing the local DFS industry and setting licensing and renewal fees.
  • Ensures that while operators with less than 7,500 users must register with the state, they do not need to apply for a license.
  • Prohibits operator employees from playing.
  • Forces operators to make sure data is secure and player and operator funds are segregated.
  • Prohibits DFS contests that involve amateur sporting events, including college sports.
  • Sets 18 years as the minimum age for DFS users.

Major operators, FanDuelDraftKingsYahoo and Fantasy Draft, have all been licensed and continued to operate in the Colorado market since the law passed.

There is no tax on operator revenue.

Colorado gambling revenues

According to the American Gaming Association’s 2019 “State of the States” casino revenue roundup, casinos in Black Hawk, Central City and Cripple Creek posted a combined $842.1 million in revenue in 2018.

That marked a record for Colorado gaming and a 1.7% increase over the $828 million the industry posted in 2017. It was also a 13% increase over 2014 when there were even more commercial casinos operating in Colorado.

Thanks mostly to the launch of legal sports betting, 12 of 24 states with commercial casinos also posted record revenues in 2018. The US casino industry brought in an all-time high of $41.7 billion in revenue, up 3.5% over 2017.

Eight states made betting on sports legal in 2018 with US-wide sports betting revenue going up 64% to $430.2 million.

Original estimates claimed the state could generate $20 million or more from the 10% tax that it will charge legal sports betting operators in the state. That would mean Colorado casinos and online gambling operators will be posting an additional $200 million a year in gambling revenue.

However, the governor’s office now estimates it will collect between $1.4 million and $1.7 million in sports betting tax revenue in the first year, ramping up to, at most, $10.4 million in the 2020-21 fiscal year. It is a more conservative estimate of an additional $100 million in gambling revenue in the first full year with legal sports betting in Colorado.

History of gambling in Colorado

Colorado has allowed pari-mutuel betting on horse races since 1949. Plus, there’s been a state lottery in Colorado since 1983.

However, Colorado gambling didn’t kick off until legal casino gambling came to the once sleepy mountain towns of Black Hawk, Central City and Cripple Creek in 1991.

These former mining towns were on the verge of becoming ghost towns when Colorado voters approved Initiative 4 to the Colorado constitution, allowing for limited gambling operations in these three cities only to save the failing local economies.

Only slots, blackjack, and poker were allowed, single bets could not exceed $5, and the casinos could not run 24 hours a day. Still, small casinos opened up and persevered under these restrictions in Black Hawk, Central City and Cripple Creek.

In 2008, the hope for increased revenue came in the form of Amendment 50. It sought to approve craps and roulette, allow the casinos to take bets of up to $100 and stay open 24 hours. Voters approved and revenues have been climbing ever since.

All three towns have been transformed from failed mining towns to quaint gambling destinations. 

Most of the smaller casinos are reminiscent of Old West saloons. There are 33 among the three towns, the largest of which are in Black Hawk.

Of course, Central City is just a few miles away, and both are less than an hour’s drive from downtown Denver. 

Cripple Creek is about an hour from Colorado Springs in the southeastern part of the state. Two tribal casinos owned and operated by the Ute tribe have also opened on the western side of the state.

Colorado still has live and simulcast horse racing at Arapahoe Park, just outside of Denver. Plus, 12 other off-track betting locations throughout the state.

The state lottery still runs and participates in the Mega Millions and Powerball multistate draw games.

Now, sports betting is coming to the state. Also, 28 of the 33 casinos have already applied for sports betting master licenses, Colorado gambling appears on the verge of another boom.

One that will be spurred on even further by a recent movement to allow residents in Black Hawk, Central City and Cripple Creek to decide for themselves when it comes to increased betting limits and new games.

Responsible gambling initiatives in Colorado

As the voice for the Colorado gaming industry, the Colorado Gaming Association (CGA) has issued the following responsible gaming position statement:

“(The CGA) defines problem gambling as any gambling behavior negatively impacting the lives of individuals, resulting in serious personal, financial, or legal consequences. Problem gambling takes two major forms: compulsive gambling and underage gambling, which affect both guests and employees. CGA believes problem gambling is a serious issue that deserves a proactive response from the casino industry. CGA is taking positive steps to address problem gambling because we do not want this behavior to harm our customers, employees, business operations, communities or industry. We have committed human and financial resources to promote education and awareness of compulsive gambling among our guests and employees. We have put in place policies and practices to deter underage gambling and discourage compulsive gambling. Our goal is to promote and support, to the fullest extent practical, responsible gambling behavior at every member casino of the Colorado Gaming Association.”

The CGA also offers training to casino employees, community and civic groups on the issues of problem and underage gambling.

The CGA also offers a self-exclusion program in conjunction with the Problem Gambling Coalition of Colorado (PGCC).

The program offers a voluntary self-exclusion program to those unable to gamble responsibly. Those taking advantage of the program can be removed from casino marketing lists, cancel slot club memberships, and cancel any check-cashing privileges with any and all casinos in Colorado.

The program is for those who want to cease gambling activities permanently. Casinos, including Ameristar and the Isle/Lady Luck Black Hawk, consider self-exclusion a permanent decision and will not allow even those who rescind self-exclusion to gamble.

Further resources for problem gamblers in Colorado include:

  • Colorado Gamblers Anonymous: For persons in recovery from gambling addiction. Information about meetings in Colorado and other resources is at
  • National Center for Responsible Gaming: Understands gambling disorders by funding high-quality research and creating public education initiatives. More information is at
  • National Council on Problem Gambling: This is an umbrella organization for state problem gambling councils. More information is at
  • Problem Gambling Coalition of Colorado: This program offers educational and treatment options for families in Colorado who face challenges with their gambling behaviors. More information is at
