Is Online Gambling Legal in Colorado?

Casino GamesIllegalLegal
Sports BettingLegalLegal
Horse RacingLegalLegal
Daily Fantasy SportsLegalN/A

Online gambling laws in Colorado are outdated and don’t completely cater to the new online betting framework.

Notably, Colorado only has three forms of legal online gambling: sports betting, fantasy sports, and horse betting. Let’s carefully examine the ins and outs of each one.

Types of Gambling in CO

Simply, Colorado is still hesitant to move forward with certain online gambling operations. The only online gambling that is legal in relation to sports betting. Admittedly, Colorado voters will have more than enough opportunity to make some changes in the gambling sector.

Casino Gaming

The saga of legalized casino betting in Colorado stems back to the Limited Gaming Act of 1991. In result, limited gaming became legal in three CO communities: Black Hawk, Central City, and Cripple Creek.

To further break it down, limited gaming means “casino-style” gambling, which is limited to the following terms and games:

  • $100 maximum wager (originally $50)
  • Slot machines
  • Blackjack
  • Poker
  • Craps
  • Roulette
  • Tribal reservation land

Colorado voters supported a 2008 amendment that included adding more table games, raising betting limits, and extending gaming hours to 24- hours. Additionally, the city of Cripple Creek legalized 24-hour alcohol service for of-age players.

Unfortunately, online casino operations are still prohibited in Colorado.

CO Tribal Casinos

While there are a couple of tribal casinos in Colorado, they operate in somewhat of a gray area. Even though they are on tribal land, the tribes have agreed to obey the same limited gaming bet limits that other Colorado casinos must follow.  

Regardless, tribal casinos are not subject to taxation and do not have to report their revenue to the State.

Sports Betting

Now we're turning your attention to the star of the show, sports betting. Officially legalized per HB 1327, the bill gives legal authority to the Colorado Limited Gaming Control Commission (LGCC), a Colorado Department of Revenue division.

Mainly, sportsbooks must work with casino master license holders to do business in the state. Also, the bill enforces a mandatory 10% sports betting tax, of which the profits will go to the Colorado Water Plan.

Furthermore, there are many reasons why Colorado is perfect for ALL sportsbook operators. All in all, our full Colorado betting has the details about the many perks of gambling at CO sportsbooks and which are the best ones.

Daily Fantasy Sports (DFS)

The legalization of Fantasy Sports paved the way and started a trend for the current state of sports gambling in CO. In fact, Daily Fantasy Sports became legal in 2016, with a few minor restrictions. 

Look out for a number of well-known DFS sites in Colorado, such as FanDuel and DraftKings. Although, unlike some states, Colorado prohibits betting on college sports picks.

Overall, Fantasy sports are great for testing your knowledge and skill beyond the world of sports betting. 


Undoubtedly, the most accepted form of gambling in CO is bingo. Authorized in 1958, bingo in Colorado has developed to include a large variety of bingo hall locations and tournaments.

Sadly, since the bingo law is outdated, the chances for any online support are low.
For any operators or charitable organizations wanting to hold bingo raffles, the Colorado Secretary of State manages the state's licenses.

Horse Racing

Horse racing set the stage for the legalization of gambling in Colorado. Ultimately, horse racing was given the green light thanks to a 1948 ballot.

Unfortunately, even though horse racing was off to a great start, things have drastically changed over the years. Colorado currently only has one horse racetrack left in the entire state, located in Aurora.

However, for players looking to get their horse racing fix, there are 12 off-track betting locations. OTB offers bettors simulcast and parimutuel betting possibilities. 

Some of the available legal horse racing sites in CO include:

CO Lottery

The Colorado Lottery began in 1982 with just scratch tickets. Multistate games were added over the years, including Mega Millions and Powerball.

CO voters decided in 1992 that they wanted the Lottery proceeds to go to outdoor recreation, parks, trails, rivers, wildlife, and open space. Hence, 100% of the profits from lottery game sales are given back to the assigned state projects.

The state recipients that get the lottery profits are:

  • Great Outdoors Colorado (GOCO) 50%
  • Conservation Trust Fund (CTF) 40%
  • Colorado Parks and Wildlife (CPW) 10%
  • Any profits made over the annual cap go to various Colorado Education funds.

Unlike the handful of states with a diverse lottery program, Colorado does not offer any online lottery options. In fact, CO has a mobile lottery app, but it only allows users to do a few things, such as scan tickets or view jackpot results.


Online poker is currently not legal in the Centennial State. Sadly, when the Limited Gaming law was enacted, poker was on the list of table games. 

Even with the recent advancements in the online gambling industry, it will take more of an effort to change that aspect of the Limited Gaming law. While this may be true, elected leaders recently voted in favor of Amendment 77 to lift betting limits across the state.

On the other hand, poker players can take advantage of in-person poker at the 50+ tables across Colorado; most of them are located in Black Hawk.  

Colorado Gambling Law

Colorado took a historic step in the right direction in 2020 with the legalization of online sports betting. Typically known for its liberal agenda, Colorado is not as enthusiastic about legalizing online gambling.

So, when voters made their way to the polls, the final result was an almost even tie on the Colorado sports betting ballot. Still, sports betting officially received the go-ahead.

Unfortunately, this still means that no other form of online gambling is legal-yet.

Here are the key gambling milestones throughout Colorado history:

Local License Holders

On top of having many land-based casinos, the method for obtaining betting licenses in Colorado can get complicated.

Here are some key points relating to licenses, fees, and operators:

  • The 33 casinos can offer mobile, retail (in-person), or online sports betting.
  • Master licenses are only available to state casinos in Central City, Cripple Creek, and Black Hawk.
  • Master Sports Betting License applications are $10,000, and $125,000 upon approval.
  • Licenses must be renewed every two years.

Suffice to say, there is a large variety of sports betting operators in CO, which is certainly beneficial for players in every way.

Some further alternatives to manage problem gambling are:

Additionally, the CO Lottery joined the World Lottery Association in 2018 to better improve Colorado residents' Responsible Gaming program.

CO Gambling Tax Rate

Of course, each state has its own set of rules, especially when it comes to taxes. Fortunately for prospective sportsbook operators, Colorado has a low 10% tax rate.

For any other betting, such as any limited gaming, the tax rate is based on a sliding scale. The scale changes according to the adjusted gross revenue. For example, the scale starts at .25% tax rate for the first $2 million in revenue.

Besides the operator tax rates, individuals are subject to report their winnings as well. For example, the tax for larger winnings gets withheld by the operator on your behalf, but you must still report it on your tax return.

Typically, the winning limits for automatic tax deductions are dependent on the game, and they include:

  • Sports Betting: $600 and 300x your stake
  • Horse Racing: $600 and 300x your stake
  • Poker Tournament: $5,000
  • Slot Machines: $1,200
  • Bingo Games: $1,200
  • Keno: $1,500

Although our duty at is to inform you, we always recommend speaking to a professional accountant about all of your tax concerns.

Payment Methods in CO Gambling Sites

Safety and security are at the top of our priority list. Therefore, we recommend only playing at legal and licensed CO casinos and sportsbooks

While this list includes the most common and secure payment methods, they do vary at each operator.

The Future of CO Online Gambling

All in all, CO online gambling is off to a great start with the approval of online sports betting, but the state needs more.

Although it is a waiting game, we expect changes to occur this year. One thing we know for a fact, the approved increase to limited gaming betting limits will do wonders for the population of the three main gambling towns, and the overall revenue for everyone involved.
