We will show you the best online casinos to play for real money in Colorado, and the nuances behind online gambling laws in the state.

Casino GamblingColorado features 35 commercial casinos spread among three towns, including Blackhawk, Central City, and Cripple Creek. It also has two tribal casinos in the southwestern part of the state.
PokerPoker rooms are legal as long as they are within licensed casinos. Ameristar Blackhawk and Bally’s Black Hawk West are the state’s most notable poker establishments.
Horse Racing BettingHorse racing became the first legal form of gambling in Colorado in 1948. It offers parimutuel betting at Arapahoe Park (Aurora area) and a dozen simulcast facilities.
Dog Racing BettingColorado Lawmakers banned dog racing in 2014. But this action was a moot point because the last dog track closed in 2008. 
LotteryThe Colorado Lottery has been operating since 1983. It offers a variety of in-state drawings and scratch cards. Coloradans can also participate in the multi-state Powerball and Mega Millions drawings.    
Daily Fantasy SportsThe Centennial State became one of the first to legalize daily fantasy sports, doing so in 2016 through H 1404.
Sports BettingVoters passed a referendum (Proposition DD) in November 2019 to legalize retail and online sports betting. Colorado now features many legal retail and online sportsbooks.
Charitable GamingCharities earned the right to host gambling fundraisers in 1958. Qualified charities can offer bingo games and raffles.
Social GamingSocial gambling is legal in Colorado, provided nobody profits through rake, drink sales, or other means. Any efforts to profit off social gambling functions are illegal “professional gambling” as per state laws.

Best Colorado Online Gambling Sites

Dozens of offshore online casinos serve CO gamblers. The Gamble Online team has reviewed many of these gambling sites to determine the best options.

We consider important features such as their game variety, payment speed, banking methods available, and quality of bonuses.

Where to Gamble in Colorado

Many brick-and-mortar and online gambling opportunities are available in the Centennial State.

This section covers where to gamble in Colorado, including land-based casinos, horse racing venues, sportsbooks, bingo halls, and poker rooms.

Land-Based Casinos in Colorado

The Centennial State legalized brick-and-mortar casinos before many states, doing so in 1991. However, the Colorado Limited Gaming Act of 1991 featured notable restrictions:

  • Casinos could only accept up to $5 maximum bets and had limited hours of operation from 8 a.m. until 2 a.m. It also confined casino gambling to Black Hawk, Cripple Creek, and Central City.
  • The town restrictions remain, but the other limiting factors are gone. A 2008 amendment increased max casino bets to $100 and allowed venues to add craps and roulette games.
  • In 2021, the state allowed casino operators to determine their max wagers, like Vegas and other major gambling hubs.

The missing restrictions have helped make Colorado one of the biggest casino states. It now offers 35 commercial gaming venues and two tribal casinos.

Ameristar Blackhawk is the state’s largest casino, with over 1,300 slot machines and 40 table games.

Horse & Dog Tracks

Colorado regulated its first form of gambling in horse racing in 1948.

It has a limited horse betting scene, with only Arapahoe Park running full-time. Other options include county fairs and 12 simulcast facilities.

Dog racing betting was available up until the last track closed in 2008. A 2014 ban on the sport officially ended dog racing wagering.

Online Sports Betting

Colorado legalized online sports betting through a voter referendum in 2019.

The measure passed by a slim margin of 45,000 votes (51.4% in favor). Despite voters’ mixed feelings, Colorado betting apps have been quite popular since launching. Players can also access sportsbooks online to make their bets instead of downloading an app.

Retail sportsbooks are also available at commercial casinos. Nearly 30 retail betting venues operate at casinos like Bronco Billy’s, Grand Z, and Isle Casino of Capri.

Bingo Halls and Charitable Gambling

Legitimate charities can host raffles and bingo games. Unlike in many other states, they cannot hold casino nights.

The CO Secretary of State website offers helpful FAQs regarding how charities can legally run gambling functions.

Social Gaming at Home

The Colorado Revised Statutes (CRS) on gambling define legal social gaming as follows:

“[…] game incidental to bona fide social relationship, participated in by natural persons in no way connected to professional gambling.”

Professional gambling does not refer to poker pros or other skilled gamblers. Instead, it alludes to those who profit from games of chance.

In short, you can enjoy home poker games with friends and acquaintances as long as nobody collects rake.

Poker Rooms and Clubs

Colorado poker rooms felt the sting of the previous limitations on betting. Until 2008, they could not allow players to put over $5 into the pot.

However, gambling amendments in 2008 and 2021 now allow high-stakes casino poker. These amendments have helped poker rooms like Ameristar (22 tables) and Bally’s Black Hawk West (17 tables) grow.

Real Money Online Casino Games for Colorado

Trusted offshore casinos provide several types of online casino games to Coloradans. You can see the available games and their main features below.

Online Slots

The average offshore online casino in Colorado provides anywhere from 100+ to 300+ real-money online slots.

Therefore, you can expect many options regarding Colorado online slot machines. Many of these games boast entertaining bonus rounds and features like expanding wilds and cascading reels.

The brick-and-mortar casinos here collectively feature over 13,000 slot machines, and you can only play slots in Cripple Creek, Central City, and Black Hawk.

Online Poker

Online poker became popular in Colorado during the 1990s and 2000s when land-based bets maxed out at $5. Although unregulated at a level state, poker sites remain popular thanks to convenience, frequent promotions, and big tournaments.

Online gambling sites also offer many forms of video poker, such as Jacks or Better, Poker Bonus, and many other exciting variations.

Of course, CO land-based poker rooms have become more attractive due to the bet cap dissolving. Poker clubs are available in various casinos in Black Hawk, Central City, and Cripple Creek.

Notable poker rooms include Ameristar, Bally’s Black Hawk West, Monarch (11 tables), and Midnight Rose (9 tables).

icon blackjack stand green


Online blackjack was the only way to play this game in Colorado until the 2008 casino amendment. It is still available through offshore online casinos with multiple variations.

Common online blackjack variants at gambling sites include classic, Face Up 21, Perfect Pairs, and Super 21.

Blackjack is a staple in Colorado’s brick-and-mortar casinos. You can play this game for anywhere from $5 to $25 per hand, while on gambling sites, bet ranges can go from $1 to $100.

Live Dealer Games

Land-based casinos are not easily accessible to some players because they are only available in three towns. The good news is that live dealer casino games let you enjoy the land-based gambling atmosphere without traveling.

Live games are part of certain online casinos like Bovada and DuckyLuck. They stream live casino games with real dealers from professional studios.

Typical live games include baccarat, blackjack, casino hold ’em, Early Payout Blackjack, and roulette.

Other Available Games at Online Casinos in Colorado

The games discussed above are the most popular options available at CO online casinos. However, you can also enjoy other exciting games, including the following.

Top Bonuses and Promotions at Colorado Gambling Sites

Colorado Online Gambling Laws

Like other states, Colorado prohibits unapproved forms of gambling. However, it makes several exceptions for regulated gambling and tolerates offshore gambling sites.

You can better understand Colorado’s online gambling laws by reading the following points.

Is Online Gambling Legal in Colorado?

Legal forms of online gambling in Colorado include sports betting and DFS (daily fantasy sports). Daily fantasy received approval through H1404 in 2016, while online sports betting became regulated through Proposition DD in 2019.

Online casinos and poker rooms remain unregulated in the state. However, offshore casino sites have served Coloradans without incident since the mid-1990s.

The Colorado Department of Revenue notes that “internet gambling is illegal under state laws.” But you should consider that local authorities have never taken action against offshore operators.

State laws seemingly apply to those running unregulated gambling sites within state borders.

We do not foresee any immediate scenario where offshore poker rooms and casinos would stop serving Colorado. Additionally, authorities have never arrested or prosecuted anybody for playing at unregulated sites.

Transmitting Gambling Information Is Illegal

CRS 18-10-106 notes that communicating gambling info through the telephone, radio, or other means is illegal.

This rule applies to would-be operators inside of Colorado. Offshore online casinos and poker sites operate outside the state and hold licensing in their respective jurisdictions.

Nobody Has Gotten in Trouble for Gambling Online

No Coloradan has faced legal trouble for playing at offshore gambling sites, and we do not expect this trend to change.

If somebody did get in trouble for gambling online, it would be a petty offense subject to the following punishments:

  • Up to a $300 fine.
  • Up to 10 days in jail.

Illegal Operators are Known as Professional Gamblers

Professional gambling means something different than card counters or pro sports bettors in Colorado.

It refers to entities that profit through illicit gambling operating within the state borders.

First-time penalties for this class 2 misdemeanor include:

  • Up to a $750 fine.
  • Up to 120 days in jail.

Colorado Online Gambling vs. Neighboring States

You may be interested to know what forms of gambling Colorado’s neighbors offer. Likewise, you might want to know if these bordering states are strict on online gambling.

The following table provides an overview of how the closest states treat games of chance.

The Centennial State has an interesting mixture of neighbors regarding gambling. Oklahoma, to the southeast, has more casinos than any state besides Nevada. On the other hand, Utah to the West does not permit any form of gambling.

Colorado has more in common with Oklahoma and its other neighbors than Utah. It has regulated almost everything except online casinos, which lie in a gray area.

The bordering states fall in line because they all tolerate offshore online gambling gambling—even Utah!

Pros & Cons of Gambling in Colorado

You can enjoy some distinct advantages when gambling in Colorado. But you also want to consider the potential drawbacks when playing here.

The following pros and cons will help you determine whether to gamble in this state.


  • You can play at legal and licensed DFS and betting sites in Colorado.
  • This state is relaxed towards offshore poker and casino sites.
  • Many land-based casinos; 35 commercial and two tribal casinos.
  • There are plenty of big promotions available online.
  • Historic casino towns; Central City, Cripple Creek, and Black Hawk are old mining towns with plenty of history and mountain scenery.


  • Land-based casino gaming is inconvenient if you do not live near one of the state’s three casino hubs.
  • The Colorado 4.63% flat tax on gambling winnings is higher than the average state. By comparison, states like Florida and South Dakota do not tax gambling wins.
  • Colorado has yet to legalize and regulate online poker and casino games.

Future of Online Gambling in Colorado: Our Prediction

The Centennial State offers legal online sports betting and DFS, but it still has a ways to go for a complete online gambling market.

Online casinos and poker rooms remain unregulated in the state, with no clear picture of when/if they will become legal. Unlike mobile sports betting, gambling sites and poker have not received a big push.

The Department of Revenue has begun discussing the possibility of legalizing online casino gaming in Colorado in the future. But legislation and a voter referendum would still need to happen before Colorado online casinos regulated inside the state become available.

Of course, you can still play for real money using offshore online gambling sites that serve Colorado from trusted jurisdictions in the industry, such as Costa Rica and Curaçao.

Therefore, you can safely play at these sites until politicians draft an online casino or poker bill.
