Is Online Gambling Legal in Colorado?

Key Takeaways

Online Gambling at Poker Rooms Cards Chips and Dealer Icon

Online gambling is particularly attractive here because land-based casinos, poker rooms, and sportsbooks are only available in three towns and two tribal reservations.

Some gamblers do not want to drive to Black Hawk, Central City, Cripple Creek, Ignacio, or Towaoc for every session. 

But is online gambling legal? The Centennial State legalized and regulated online sports betting in 2019. You can play on regulated betting apps when you are within state lines. These sports betting apps use geolocation software to determine your location before permitting bets.

Poker sites and online casinos, on the other hand, are unregulated. Nevertheless, hundreds of offshore gambling sites serve this state, and many local gamblers use them. 

The Colorado Revised Statutes (CRS) do not specifically mention online gambling as being illegal.

Nobody has faced prosecution in 30+ years of offshore gambling and authorities have not even tried busting offshore casinos, sportsbooks, and poker sites.

This state has been hands-off with online gambling, instead focusing on potential illegal operators based within its jurisdiction.

  2. Fast & Reliable Payments

  3. Security & Safety

    A secure website (SSL encryption) is necessary for any acceptable gaming site.

Top Real Money Online Casino Games in Colorado

You can see which game types are the most popular in the Centennial State below.

Slots Reel Big Icon

Online Slots

Most CO online casinos go heavy on real money online slots, with some offering several hundred titles.

This wide variety ensures many themes, features, and styles of graphics.

You can also pay for big jackpots through these slot games, including over $1 million via Aztec’s Millions.

Over 14,000 slot machines are available at CO land-based casinos. You will have many options available on a casino trip to Black Hawk, Central City, or Cripple Creek.

However, you may find such trips inconvenient if you do not live near those places.

Online slots are a good substitute for spinning the reels when you do not want to travel.

Stack of Poker Chips Icon

Online Poker

Poker sites offer an opportunity to play cash games and tournaments in this state 24/7.

The latter is critical because most Colorado poker rooms are open from 8 a.m. to 2 a.m. Online casinos provide an opportunity to play late-night sessions.

Colorado online poker rooms typically feature cash stakes from $0.02 to $10 and 5% rake. The state’s live poker venues usually offer games ranging from $1 to $20 and 10% rake up to $5.

Online tourneys are much bigger than live tourneys in the Centennial State. Some online poker tournaments in Colorado can boast $100,000 or $200,000 guaranteed prize pools.

Live rooms often run a limited tourney schedule that includes small weekly events.

Online Blackjack

Gaming sites provide a cheap way to enjoy blackjack in this state. Real-money blackjack starts at $1 per hand and maxes out at $500.

The common rules are player-friendly, including 3:2 natural blackjack payouts, dealers standing on a soft 17, and doubling down after splitting.

Colorado land-based casinos offer the same favorable rules, making their blackjack games more attractive than some states.

However, the stakes begin at $10 or $15 per hand.

Live Dealer Casino Icon

Live Dealer Games

Nothing beats the experience of playing table games at brick-and-mortar establishments.

However, CO casinos are centralized in three main areas: Cripple Creek, Central City, and Black Hawk. 

Live dealer casinos are great alternatives if you do not live near one of these areas.

They let you enjoy land-based baccaratblackjackroulette, and more. The stakes are cheaper than most brick-and-mortar tables at $1-$5 a hand.

Qualified charities that have existed in this state for +5 years can run bingo games and raffles. The CO Secretary of State’s website provides more info on charity gambling.

Colorado Gambling Laws: A Deep Dive

The Centennial State has legalized every major form of land-based gambling, ranging from casinos to horse racing. It also offers regulated online sports betting and DFS for mobile gamblers.

You can read more on each type of gambling in Colorado and their legalities below.

Land-Based Casinos

Lawmakers pitched casino gaming as a way to revive the historic mining towns of Black Hawk, Central City, and Cripple Creek. Thus, the idea was born to confine commercial casinos to these historic towns through the Colorado Limited Gaming Act.

The Limited Gaming Act lived up to its name because casinos could not stay open 24/7 or accept bets over $5. The industry received a boost in 2009 through Amendment 50, which enabled gaming venues to run 24/7 and boosted max bets to $100.

The passage of Amendment 77 in 2021 essentially let casinos decide their betting limits with no cap.

These amendments have allowed Colorado gaming to keep thriving and support 34 casinos. Here is a look at the distribution of casinos throughout the state:

  • Black Hawk – 15 casinos
  • Cripple Creek – 10
  • Central City – 7
  • Ignacio – 1 (tribal)
  • Towaoc – 1 (tribal)

Online Gabling

Online gambling falls into a grey Area. Colorado Statues do not consider internet gambling as illegal.

CRS 18-10-102(2) broadly defines gambling as “risking any money, credit, deposit, or anything of value for gain […].” 

On the contrary, the Colorado Department of Revenue (CDOR), which regulates most gambling within the state, states that “Internet gambling is illegal under state and federal laws.” However, no one has ever faced prosecution.

Horse & Dog Tracks

Colorado legalized pari-mutuel betting in 1948, and Centennial Race Track opened in Littleton in 1950.

The “Santa Anita of the Rockies” struggled through three decades of running horse races before closing in 1983. 

Pikes Peak Meadows launched in 1965 and did not experience much success either. The Colorado Springs horse track was converted to a motor speedway in 1993.

Arapahoe Park launched in 1993 and is the only track left in the state. This establishment runs thoroughbred and quarter-horse races from May to August. Colorado also had multiple dog tracks, including the Rocky Mountain Kennel Club, Pueblo Kennel Club, and Mile High Kennel Club.

Mile High was the last Colorado dog track, shuttering in 2008. The state completely ended greyhound racing with a 2014 ban on live racing and a 2023 ban on simulcast dog bets.

Bingo, Lottery
and Charitable Gambling

Qualified charities can use bingo and raffles for fundraisers. The Centennial State requires charity organizations to exist for five or more years before qualifying for bingo and raffles.

Voters shot down 2022 legislation (Amendment F), which would have decreased this requirement from five to three years.

As for lotteries, the Colorado Lottery has been operating since 1983. It initially only offered scratch cards but has expanded to include in-state and multi-jurisdictional drawing tickets.

Its games include Powerball, Mega Millions, Lucky for Life, Colorado Lotto+, Cash 5, Pick 3, and scratch cards.

Social Gaming at Home

Social gambling is legal in Colorado, provided nobody profits from collecting rake or sales (e.g., alcohol). CRS 18-10-102 makes an exception for home games that include a “social relationship” whereby nobody is participating in “professional gambling.” 

This state defines professional gambling as “participating in gambling and having, other than by virtue of skill or luck […] a greater chance of winning [versus other players].” In short, gambling with friends for fun is legal so long as nobody acts as the house.

Poker Rooms and Clubs

A dozen legal poker rooms are available throughout the Centennial State.

Ameristar Black Hawk highlights the list with 22 tables and 24/7 availability. The Lodge and Isle Casino (both in Black Hawk) also have large poker rooms with 18 and 17 tables, respectively. However, they are only open from 8 a.m. to 2 a.m.

Midnight Rose (Cripple Creek) only provides nine tables, but it has a nice game variety with Texas Hold ’em, Omaha Hi-Lo, and seven-card stud. By comparison, most Colorado poker rooms only offer Hold ’em and Omaha.


Retail and online sports betting became legal in Colorado through a November 2019 vote.

Land-based and online sportsbooks were launched half a year later, in May 2020. This state has attracted many operators, with 20 betting apps and 12 brick-and-mortar sportsbooks running.

Bettors can wager on everything except college prop bets and esports. Lawmakers excluded esports betting because some pros are under 18 years old.

Colorado Gambling vs. Neighboring States

The Centennial State has diverse neighbors, ranging from the casino-happy Oklahoma to ultra-conservative Utah. The following table compares Colorado and bordering states in several key gambling categories.

Colorado is on par with most of its neighbors regarding legal forms of gambling. Utah is the obvious exception because the Mormon State prohibits all bets. Oklahoma is also notable because it has yet to legalize sports betting.

Speaking of which, Oklahoma ranks second behind only Nevada with 134 casinos. Colorado is a distant second among this group, with 34 casinos.

All listed states treat online casinos as a grey area except for Utah.

A Brief History of Colorado Gambling

The state has a fascinating gambling history that involves legends like Doc Holliday and Bat Masterson. Let’s discuss how Colorado gambling has progressed from Wild West saloons to online sportsbooks.

Mid-to-late 1800sLeadville becomes a Wild West gambling haven for legends like Holliday and Masterson during a silver boom.
1948Voters approve pari-mutuel betting, making it the first legal form of gambling in Colorado.
1950Centennial Race Track opens and offers horse races and pari-mutuel wagering.
1958Voters amend the constitution to allow charity gambling—specifically bingo.
1982The state votes yes on lottery games; the Colorado Lottery launches the following year with scratch-offs.
1990Voters approve the Colorado Limited Gaming Act, which permits casinos in Black Hawk, Central City, and Cripple Creek. The “limited” aspect means $5 max bets and select hours of operation.
1992Arapahoe Park begins offering horse racing; it is the only active race track in Colorado today.
1995The Southern Ute Indian Tribe (Sky Ute Casino Resort) and Ute Mountain Ute Tribe (Ute Mountain Casino Hotel) negotiate gaming compacts with the state.
2008Amendment 50 passes and enables Colorado casinos to stay open 24/7 and raise betting limits to $100. The Mile High Kennel Club ceases operations, thus ending the state’s live dog racing scene.
2014Gov. John Hickenlooper signs legislation to ban greyhound racing in the state.
2019Voters pass Proposition DD and usher in legal retail and online sportsbooks.
2021Amendment 77 passes and ends state-imposed casino betting limits; casinos can now decide their max wagers.
2023Gov. Jared Polis signs HB23-1041, banning in-state simulcast betting on dog races.

Colorado Responsible Gambling Initiatives

The CO Department of Revenue leads responsible gambling efforts in this state.

It requires casino and sportsbook operators to offer a self-exclusion option. Self-exclusion refers to voluntarily banning yourself from gambling establishments either temporarily or permanently.

The CDOR also provides various resources to help anybody with a gambling problem. Examples include the Problem Gambling Coalition of Colorado and Kindbridge Behavioral Health.

Summary: Colorado’s Gambling Journey

Colorado has gone from unregulated gambling in Wild West mining towns to one of the biggest gambling states.

It has one of the country’s largest gaming industries, with 32 casinos available in Cripple Creek, Central City, Black Hawk, and two more in tribal reservations. It also has 12 land-based sportsbooks and 20 sports betting apps.

The Centennial State added legal online betting to its gambling offerings in 2020. However, it does not appear close to regulating online casinos and poker sites. These remain the only major forms of unregulated CO gambling.

We would not be surprised if this state-regulated Colorado online casinos and poker rooms in the next 5-10 years. However, we do not see this situation unfolding in the next 1-5 years.

Until then, offshore casinos and poker sites will remain safe gambling options in the state.

Colorado Gambling FAQ

The following FAQs provide further clarity on the Colorado gambling market. You will find questions and answers on CO casinos, problem gambling, no-deposit bonuses, and more.

How do tribal casinos differ from commercial casinos in Colorado?

Tribal casinos do not have to be in the towns of Central City, Cripple Creek, and Black Hawk like commercial casinos. The Sky Ute Casino Resort is in Ignacio, CO, in the southwestern part of the state. Ute Mountain Casino Hotel lies 45 miles west of Sky Ute, closer to the Utah and Arizona borders.

Is there any risk of playing at online casinos regulated outside of Colorado?

The Colorado Department of Revenue: Special Business Group does not regulate offshore gambling sites like it does land-based casinos. Therefore, you have nobody to intervene during possible disputes with online casinos. We recommend choosing the best Colorado online casinos to avoid hassles with unsavory operators.

Who regulates online casinos in Colorado?

CO online casinos are licensed and regulated in offshore jurisdictions like Panama and Curaçao. They are not subject to regulation by the CO Department of Revenue: Special Business Group like Colorado land-based casinos and sportsbooks.
