Colorado sports betting was legalized in the state in November 2019 and went live both at brick-and-mortar venues and online in May of the following year. While bettors in CO have access to regulated sportsbooks, they can also safely enjoy the offerings of offshore sports betting sites that often provide a more flexible betting experience.

In this guide, we look at the top offshore sportsbooks CO bettors can enjoy, how to sign up with them, and what they offer. We also briefly examine the laws and taxes surrounding sports betting in the state.

List of the Best Colorado Sports Betting Sites

Although bettors in Colorado have over 26 online sports betting apps they can use, these come with various restrictions and don’t accept crypto payments. However, bettors can also safely use offshore sportsbooks that are more flexible in terms of what they offer. Below, we offer our experts’ list of their top ten offshore sites for sports betting in Colorado.

  1. BetOnline – The best online sportsbook in Colorado overall
  2. Bovada – Top CO sportsbook for live streaming
  3. BetNow – Excellent for in-play wagers
  4. Everygame – Top Colorado sportsbook with parlay builder
  5. BetUS – Great sportsbook for crypto options and promos
  6. MyBookie – Simple to use offshore CO sportsbook
  7. BUSR – Great for horseracing and crypto bonuses
  8. – Fast payouts and high limits
  9. XBet – Renowned racebook and prop bets
  10. Lucky Block – No-KYC crypto sportsbook in CO

Online sportsbooks constantly improve and update their features. But one aspect they cannot control is how long it takes for fiat currencies to payout. As a result, bettors looking for instant payouts are turning to crypt-centric sportsbooks like Lucky Block, which offers instant withdrawals with zero transaction fees and anonymous transacting. Because the site is not yet available in the US, bettors will need to access Lucky Block using a VPN, which the sportsbook encourages.

But, if you would prefer to fund your account using traditional options like credit and debit cards, take a look at the links below:

Reviews of the Best Sportsbooks in CO

Now that we have our list of the best sites for online betting in Colorado let’s review each more closely to see what they offer, what makes them stand out, and why we recommend them. Although these are offshore sports betting sites, they are safe and easy to use, so let’s get started.

1. BetOnline – The best Colorado sports betting site overall


  • Payout time: 24-48 Hours
  • Established: 1991
  • License: Panama Gaming Authority
  • Headquarters: Panama City, Panama

Our Verdict: 5/5

The leading Colorado sports betting site on our list is BetOnline. This site, which is over 30 years old, provides bettors with one of the best offshore gambling sites, featuring an online casino, racebook, sportsbook, and live betting suite. Additionally, bettors can find Esports betting here.

BetOnline stands out for many reasons, its early release of lines that ensure bettors enjoy the greatest odds, its diverse selection of sports markets and payment methods, and its outstanding reputation.

Sports Betting Options at BetOnline: 5/5

The selection of sports markets offered by BetOnline is vast, covering over 35 options, including baseball, football, hockey, cricket, tennis, and Esports. While this collection is larger than that provided by most competitor sites, BetOnline stands out more for its odds. Since the sportsbook releases its lines earlier than competitors, it provides bettors with the most competitive and impressive odds in the state.

Payment Options: 5/5

Like its selection of sports markets, BetOnline’s payment options are diverse and cover a range of methods, from credit cards and bank transfers to over 18 cryptocurrencies. Included in the crypto options are Bitcoin, Litecoin, and Ethereum. Additionally, the site ranks as one of the best Dogecoin gambling sites, thanks to the instant and feeless payouts.

Customer Support: 4.9/5

Customer service is available around the clock at BetOnline. It comes in two forms, a live chat facility where bettors can communicate directly with a support team member and an FAQ section that answers more general questions.

Bonuses & Promos: 5/5

Bettors with BetOnline promo codes can access a plethora of exciting promotions, from welcome and reload bonuses to crypto promos, odds boosters, rebates, and free bets. In most cases, these have low wagering requirements and minimal qualifying deposits, as seen below.

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?
Sports Sign-up Offer 50% Welcome Bonus up to $1,000 BOL1000 10x $55       ✅
Reload Bonus 25% reload bonus up to $250 BOL1000 6x $50
$25 Risk-Free Props Builder Wager Get $25 in Free Play if your first-ever wager loses. N/A 6x $25


  • Wagering requirements below 10x
  • Assorted generous promos
  • Releases lines early
  • Offers Esports betting


  • Live streaming unavailable
  • No credit card withdrawals

2. Bovada – Top CO sportsbook for live streaming


  • Payout time: 24 Hours
  • Established: 2011
  • License: Curacao Gaming Commission
  • Headquarters: Costa Rica

Our Verdict: 4.9/5

Since its launch in 2011, Bovada has earned a reputation among gamblers as one of the best Bitcoin poker sites. But the site has more to offer, including an Esports betting suite, a racebook, a live betting suite, and an outstanding sportsbook.

Bovada ensures bettors enjoy a large selection of pre-game and in-play wagers. But the main highlight of this Colorado sports betting site is its unique features. For instance, active bettors can live-stream sports events from the Bovada site in real time.

Sports Betting Options at Bovada: 5/5

While the selection of sports is less diverse than that covered at BetOnline, Bovada offers an impressive variety of options, including the NFL, UFC, MLB, NBA, NFL, Esports, cricket, and tennis. Bettors can also enjoy various betting lines, which they can use for pre-game and in-play wagers.

Payment Options: 4.7/5

Bettors transacting on Bovada can use several fiat currencies, like credit cards and bank wire transfers. But remember, these come with fees and can take weeks to pay out. Alternatively, bettors can deposit and withdraw funds without paying fees by using the site’s crypto options like Bitcoin and Litecoin.

Customer Support: 4.9/5

One of the talking points of Bovada is its blog, which covers various topics, giving bettors detailed descriptions of how to place specific wagers, betting rules, and other popular themes. Bettors can use this or the site’s FAQ section to gain answers or the 24-hour live chat function.

Bonuses & Promos: 4.9/5

Bovada bonus codes make it easy for new and existing bettors to unlock and enjoy various promotions. In addition to welcome packages, the sportsbook provides rebates, free bets, and reloads, as shown in the table below:

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?
Sports Sign-up Offer 50% up to $250 BVD1000 5x $20


  • Offers diverse betting options
  • Live streaming for active bettors
  • Top site for Esports
  • Fantastic blog and FAQ section


  • High transaction fees for some payment options
  • Sports selection could improve

3. BetNow – CO’s top betting site for in-play wagering


  • Payout time: 24 Hours
  • Established: 2017
  • License: Curacao Gaming License
  • Headquarters: Curacao

Our Verdict: 4.6/5

BetNow hit the online betting market in 2017 and has gained a following thanks to its sleek and user-friendly interface and exciting live betting suite. Offering a mobile-optimized website, bettors from across CO can enjoy mobile wagering using BetNow.

But, the highlight of this sportsbook is its live betting suite, which makes it simple for bettors to place wagers on sports events already in play. While these odds fluctuate, BetNow ensures its bettors enjoy the most competitive options for an outstanding live betting experience.

Sports Betting Options at BetNow: 4.8/5

In addition to being one of the best soccer betting apps, BetNow provides players with several sports to bet on using pre-game or in-play wagers, including basketball, hockey, tennis, football, and golf. While the pre-game betting at BetNow is great, the live betting is even better and offers bettors a nail-biting wagering experience.

Payment Options: 4.3/5

BetNow imposes relatively low maximum deposit limits and, as a result, may not be the best choice for high rollers. Additionally, the selection of payment methods is slim and covers options like Visa, American Express, Bitcoin, and Litecoin.

Customer Support: 4.4/5

Similarly to Xbet, the customer service options at BetNow are only available to those who have signed up and created an account with the sportsbook. However, a live chat and email facility are offered and function around the clock.

Bonuses & Promos: 4.4/5

BetNow provides a selection of bonuses for new and existing bettors. Generally, these have low wagering requirements and low qualifying deposits of $20. But many feel they are not as generous as they could be, so let’s look:

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?
Sports Sign-up Offer 150% up to $500 BN100 12x $20
15% Reup Bonus 15% up to $500 BN100 3x $20


  • 3x wagering requirements on some promos
  • Excellent site for live betting
  • Covers unique sports
  • Fantastic odds on soccer events


  • No support offered to visitors
  • Minimal withdrawal methods


4. Everygame – Features a parlay building option


  • Payout time: 48 Hours
  • Established: 1996
  • License: Curacao e-Gaming Authority
  • Headquarters: Basseterre, Saint Kitts and Nevis

Our Verdict: 4.8/5

Intertops launched in the early 90s and quickly became the go-to site for sports betting. However, to keep up with the times, the sportsbook rebranded in 2020, emerging as Everygame, a flashy new Colorado online sports betting site.

In addition to a new look, Everygame offered several new features and an extensive selection of sports betting lines, including the option for bettors to build parlay wagers on their favorite sports.

Sports Betting Options at Everygame: 4.8/5

While Everygame doesn’t offer a dedicated racebook, the site includes horse racing in its available markets. Additionally, bettors can enjoy Esports, handball, volleyball, tennis, football, and soccer. The site also ranks as one of the best cricket betting apps and sites. Bettors can also find varied betting lines, like props, moneylines, futures, totals, and spreads, and build parlays.

Payment Options: 4.8/5

Everygame offers a diverse number of payment methods that cover a variety of cryptocurrencies like Bitcoin, Litecoin, and Ripple. These options provide speedy payouts, anonymous transacting, and no fees, making them the most popular options on the site.

Customer Support: 4.8/5

The support options provided by Everygame are similar to those found on other competitor sites. In addition to an FAQ section, bettors can converse with a representative using live chat to resolve any urgent or personalized queries.

Bonuses & Promos: 4.7/5

The promotions provided by Everygame are diverse and generous. Here, bettors can access welcome packages that cover several deposits, free bets, and reloads. So, review the table below to find out more.

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?
Sports Sign-up Offer 100% up to $250 (over first three deposits) 3XBOOST250 4x $20           ✅


  • Top site for cricket odds
  • Multiple crypto transaction methods
  • Lowest rollover requirements
  • Exciting welcome package


  • No dedicated racebook
  • Average odds

5. BetUS – Best sportsbook for crypto promos


  • Payout time: 24-48 Hours
  • Established: 1994
  • License: Curacao Gaming Commission 
  • Headquarters: San Jose, Costa Rica

Our Verdict: 4.7/5

Another of the top sports betting sites in the US makes it onto our list of the leading Colorado betting sites. BetUS has a long-standing reputation for offering impressive sports betting options and has several unique features.

Besides diverse sports, the sportsbook features a newsroom called the Locker Room, where bettors can get the latest news, stats, and lineups that help to make more informed wagers. Additionally, there is BetUS TV, a series of videos that teach bettors about the different betting lines available for each sport and how to use them.

Sports Betting Options at BetUS: 4.8/5

Wagering at BetUS is exciting. Here, bettors can use betting markets like props, moneylines, parlays, spreads, and totals to wager on their top sports. Besides horse racing, BetUS covers all the most popular options, like the NBA, UFC, MLB, NHL, and NFL.

Payment Options: 4.5/5

BetUS has only a small selection of payment options. These include credit and debit card transactions and several cryptocurrencies. While the crypto methods tend to payout relatively quickly, the fiat currencies can take over five days to process and payout.

Customer Support: 4.7/5

While BetUS offers an FAQ section with all the answers to the more common questions it gets from bettors, it also enables players to contact the team directly using email or the 24-hour live chat facility.

Bonuses & Promos: 4.7/5

Although BetUS has many impressive features, it stands out predominantly for its generous welcome promotions. Crypto bettors, in particular, can claim exciting promos that boost their bankrolls by a fair amount. But, keep in mind, the reload reards offered are far less generous.

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?
Sports Sign-up Offer 100% up to $2,500 JOIN125 10x $100
Crypto Sports Sign Up Offer 100% up to $2,500 JOIN125 10x $100


  • Keep up with the latest news by visiting The Locker Room
  • Learn about betting at BetUS TV
  • Most generous crypto welcome promotions
  • Exciting sports betting options


  • Minimal transaction options
  • Poor reload bonuses


6. MyBookie – Most easy-to-use CO offshore sportsbook


  • Payout time: 24-48 Hours
  • Established: 2017
  • License: Curacao Gaming Commission
  • Headquarters: Costa Rica

Our Verdict: 4.9/5

Another top contributor to sports betting in Colorado is MyBookie. The site, established in 2017, features a fun but easy-to-use interface that translates well on mobile, making it a top choice among CO mobile betting fans.

Since the site’s design is simplistic but eye-catching, it provides the ideal platform for new bettors learning how to wager online. Add in the exciting sports betting options, and you have a site that experienced bettors also enjoy.

Sports Betting Options at MyBookie: 4.9/5

Although MyBookie’s odds aren’t as competitive as those at BetOnline, the site ranks as one of the best betting apps, thanks to its wide assortment of sports markets that covers fan favorites like the NBA and NFL and less popular options like darts and badminton. Bettors can also wager on several Esports and enjoy a selection of betting lines, like spreads, totals, moneylines, and props.

Payment Options: 4.6 /5

Bettors will only find seven payment methods available at MyBookie, Visa, MasterCard, Bitcoin, Litecoin, Ethereum, and Tether. However, we suggest making use of the crypto options as these are safer, have no fees, and payout quickly.

Customer Support: 4.8/5

MyBookie’s help center is neatly tucked away, but once they have located it, bettors will find a selection of ways to contact the support team. Besides using the FAQ section, those needing assistance can use the 24-hour live chat function to converse directly with an operator.

Bonuses & Promos: 4.9/5

The variety of promotions for new and existing bettors with MyBookie promo codes is diverse. Here, bettors can enjoy free bets, welcome promos, reloads, rebates, and boosters. There is also an exciting referral program, as shown below.

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?
Sports Sign-up Offer 50% up to $1,000 MYB100 10x $50
25% Sports Reload 25% up to $1,000 MYB100 6x $100
Referral Program 200% up to $200 N/A 25x $45


  • Leading sportsbook for new bettors
  • Top betting site for mobile use
  • Speedy crypto payouts
  • Accepts Ethereum


  • Only seven transaction options
  • Reload promo has a high qualifying deposit

7. BUSR – Colorado’s most extensive horse racing betting site


  • Payout time: 48 Hours
  • Established: 2018
  • License: Curacao Gaming Commission
  • Headquarters: Curacao

Our Verdict: 4.6/5

Our following Colorado sports betting site initially launched as a racebook but has recently expanded its offerings to include a sportsbook, a live betting suite, and one of the best offshore casinos. As a result, bettors can now bet on international horse racing events and other sports.

While the site design offered by BUSR is minimalistic at best, the sportsbook places its focus on the features it offers instead and, in doing so, provides a site that is easy to use and translates well on mobile.

Sports Betting Options at BUSR: 4.6/5

CO bettors will discover a range of sports to enjoy at BUSR, including the MLB, NBA, UFC, NFL, NHL, and cricket. However, the site’s racebook is usually the highlight for many bettors. Here, they can wager trifectas, exactas, places, wins, and parlays on local and international meets, rarely covered by other sportsbooks.

Payment Options: 4.6/5

Bettors can use a handful of fiat payment methods at BUSR, but the site caters predominantly to crypto bettors, offering nine crypto payment options, like Bitcoin, Litecoin, and Ethereum. These crypto methods pay out quickly and don’t incur fees.

Customer Support: 4.7/5

The support options provided by BUSR are among some of the best and most diverse. Those needing immediate assistance can use the live chat feature or call the support desk, while bettors with less pressing matters can email the team or complete a web form on the betting site.

Bonuses & Promos: 4.8/5

BUSR has only a handful of bonuses available for bettors. But these are often generous and ensure bettors can boost their bankrolls and explore more of the options the site has to offer.

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?
Sports Welcome Bonus 150% up to $2,500 INSIDER150 10x $100
Crypto Sports Deposit Bonus 100% up to $1,500 INSIDER150 10x $100
Sports Reload Bonus Up to $500 INSIDER150 5x $100
Refer-your-Friend 250% up to $250 N/A 3x $20


  • Low 3x wagering requirement for referral bonus
  • Top coverage of racing events
  • Over eight crypto payment methods
  • Site is simple to navigate


  • Average odds
  • Not the most visually pleasing sportsbook

8. Lucky Block – Leading sportsbook for crypto wagering

Lucky Block

  • Payout time: 5 minutes to 2 bank days
  • Established: 2022
  • License: Curacao License
  • Headquarters: Curacao

Our Verdict: 4.7/5

CO sports betting fans looking for the best new betting sites may want to start with Lucky Block, a crypto-centric gambling site that launched in 2022. Here, players can find a variety of unique and exciting features and several exciting sports markets.

Because Lucky Block is a crypto-based sportsbook, it doesn’t accept fiat currencies (although bettors can purchase crypto directly from the site using credit cards). However, this means bettors can enjoy anonymous transactions, zero fees, and instant payouts of their winnings.

Sports Betting Options at Lucky Block: 4.8/5

Like BetOnline, Lucky Block has over 35 sports markets for bettors to explore, including the NFL, UFC, NHL, MLB, NBA, cricket, and tennis. Additionally, it ranks as one of the leading boxing betting apps and sites. Bettors using Lucky Block can also enjoy betting lines like moneylines, totals, props, spreads, and parlays.

Payment Options: 4.8/5

Since all the payment methods offered by Lucky Block are cryptocurrencies, like Bitcoin, Ethereum, Dogecoin, and Litecoin, they offer instant, fee-free payouts and allow bettors to transact anonymously for more secure online betting.

Customer Support: 4.6/5

Lucky Block has three support options for bettors. Here, they can use the FAQ section, email the support desk, or talk with a support consultant over live chat, which functions 24/7.

Bonuses & Promos: 4.6/5

Although Lucky Block is relatively new and only provides a handful of promotions, it ensures that bettors have a few exciting ways to boost their bankrolls using Lucky Block promo codes. Additionally, the sportsbook has no wagering requirements on its welcome reward and a low qualifying deposit of $1.

Bonus name Bonus amount Promo code Rollover Minimum deposit Bitcoin accepted?

What is the law on sports betting in Colorado?

We’ve gone through the legislature to bring you key highlights of sports betting in CO below:

Category Colorado Law
Legalization Date Sports betting was approved in November 2019
Launch Date Both retail and online formats launched in May 2020
Age Requirement Bettors must be 21+
Tax Rate(s) Sports betting revenue is taxed at 10% per R. 4.1(1) Colorado Sports Betting Rules.
Operators are permitted an amount of promotional deductions.
All wagers are subject to the 025% federal excise tax on handle.
Tax Revenue Allocation Tax collected by the regulator was recently split between the Colorado Water Plan and problem gambling programmes in the State.
Restricted Bet Types The official list of events that are permitted for wagering is regularly updated by the Colorado Limited Gaming Control Commission and can be found here.
License Fees Licenses in Colorado are due for renewal every two years. The initial fee for a master license is $2,000, whereas the renewal fee is $250.
The fee for a sports betting operator license, or internet sports betting operator license is $1,200.
Licensees also must pay an annual Sports Betting Operations Fee, which varies year-to-year. For FY2023, the fee is $73,000 for online sports betting, and $10,700 for retail sports betting.

In this guide, we cover ten of the best offshore sports betting sites available in CO. Despite being located outside the US, these sites are safe to use, and no bettor has ever faced prosecution for using them. The locale of these sportsbooks also works in their favor in that they do not have the authority to tax bettors’ winnings and, as such, provide more competitive odds. Additionally, these sportsbooks are not required to adhere to state regulations and can offer betting on political events, entertainment events, and Esports.

CO authorized sports betting in November 2019 when Governor Jared Polis signed bill HB19-1327 after it was voter-approved. In May of the following year, retail and online sportsbooks launched in the state. But because these betting platforms are based in the US, they can and do tax bettors’ sports wagering winnings. Additionally, they must adhere to regulations outlined by state legislation and, as a result, may not offer wagering on eSports, politics, or sports where athletes are younger than 18.

Because CO bettors have access to regulated and offshore sites offering Colorado sports betting, we recommend using a mixture of both, enabling bettors to experience the best of both worlds for a top betting experience.

Who can Legally Enjoy Sports Betting in CO?

Colorado online sports betting sites are easily accessible to anyone with a computer or mobile device and an internet connection. But to sign up, deposit funds, claim promotions, and place bets with regulated CO sportsbooks, bettors must be 21 years or above.

Similarly, offshore sports betting sites also require bettors to be of a specific age before they can play and withdraw funds. But in this case, the age requirement is lower and states that players must be 18 or older.

Previous Colorado Sports Betting Bills

The Professional and Amateur Sports Protection Act (1992) meant sports betting was banned at a federal level. When it was repealed by the Supreme Court in 2018, the authorization power for legalization of sports betting went to state governments. Colorado’s Taxpayer Bill of Rights, also known as the TABOR Amendment, requires new taxes to be approved by a statewide vote. Therefore any legalization of sports betting that passed through the General Assembly required a public vote.


  • HB 19-1327: Submitted by a Senator and a Representative from both parties: Rep. Alec Garnett, Rep. Patrick Neville, Sen. Kerry Donovan, and Sen. John Cooke. This bill ultimately resulted in sports betting becoming legalized in Colorado, outlining the regulatory, tax and application structure for Colorado’s sports betting regime.


  • HB 16-1404: Submitted by Rep. Dura and Wist and Sen. Cooke and Guzman. This bill was signed into law by then Governor of Colorado John Hickenlooper on 10 June, 2016. It legalized Daily Fantasy Sports in the state a precursor for sports betting.

Colorado online sports betting sites provide bettors with a range of sports markets to wager on, from fan favorites like football, basketball, and baseball, to less common options like handball, volleyball, lacrosse, and darts. Below, we take you through the most popular sports offered by our top ten CO sportsbooks and the relevant wagers bettors can place.

NFL and NCAAF Wagering on CO Betting Sites

Colorado has a firm football following, several NCAAF teams, and an NFL team, the Denver Broncos. As a result, bettors flock to the best NFL betting sites like BetOnline to place their totals, spreads, moneylines, and player props.

NBA and NCAAB Wagering at CO Sports Betting Sites

Whether bettors in CO want to back their top collegiate teams during March Madness or back the Denver Nuggets in the NBA, we recommend visiting top basketball betting sites to place spreads, moneylines, props, and totals.

Colorado Betting Sites and the MLB

Bettors looking to wager run lines, moneylines, props, totals, and futures on Major League Baseball teams like the Colorado Rockies can head to top MLB betting sites like MyBookie.

NHL – Hockey Betting in CO

Those looking to back the Colorado Avalanche in the Stanley Cup and other ice hockey events can visit online sportsbooks like Everygame to place spreads, totals, props, and moneylines.


Another popular sport to wager on in Colorado is golf. Bettors looking to wager on top tournaments like the PGA and The Masters can visit golf betting apps like BetOnline to back the golfers they predict will finish in the top five, top 10, top 15, and top 20 or the player most likely to be the outright winner.

Horse Racing

Colorado offers legal horse racing, and as a result, bettors looking to wager exactas, trifectas, places, wins, and parlays on the latest racing meet can visit the top horse racing betting apps and sites like BUSR to stake their bets.

DFS in Colorado

Colorado officially legalized Daily Fantasy Sports in 2016. As a result, bettors in the state can visit sportsbooks like DraftKings and FanDuel to place wagers on fantasy teams and players.

In addition to offering bettors a selection of sports markets, offshore Colorado betting sites provide various betting lines that allow bettors more ways to bet on their favorite sports. Below, we review each of the most popular betting markets offered and how they work.


The most popular and straightforward wager placed on sports is the moneyline. When placing this wager, bettors put money on the team they predict will win. In sports betting, the team predicted to win is called the “Favorite” and features a minus (-) sign followed by three digits that show how much a bettor must put down to win back $100. Then, the opposing team is called the “Underdog.” This team or athlete is shown with a plus (+) sign followed by three numbers that show the amount bettors will win off a $100 bet should that team win.


Spread betting is a popular way to wager on sports like basketball (in baseball, this is called the run line.) Here, online bookies add or remove points from one or both teams to even the playing field and balance the odds. For instance, a CO sportsbook may add a +1.5 margin, where the favorite must win by two points or more for a bettor to win their bet.


Here, bettors wager on the final combined score of both participating teams. Prior to the event, the sportsbook releases its prediction for the final combined score. Then, bettors must put their bets on whether they predict the total will be more than what the bookie proposes (over) or less than (under).


The Colorado betting sites on our list give bettors more ways to win by offering them gam and player props that focus on various aspects of the game rather than the outcome. These prop wagers can relate to the game or player performance. For instance, bettors can wager on when they predict the first touchdown will take place or which player will score the first home run.


As the name suggests, futures bets see bettors wagering on events yet to take place. For example, bettors can back the team they predict will win the NBA Championships overall or which athlete will win player of the season.


Considered the riskiest bet of them all, the parlay consists of several smaller wagers called “legs.” These legs can all cover a single game or take place over several matches. To win their parlay and collect their winnings, a bettor must win all the legs of their bet. Losing a single leg causes the entire parlay to fold.

Live betting

Colorado sports betting sites provide pre-game wagering that comes with fixed odds. However, many also offer in-play or live betting where bettors can wager on games already in action. In this case, the odds fluctuate according to how the match progresses, offering bettors a more nail-biting experience. While all of our listed betting sites offer in-play wagering, we recommend BetNow as one of the best live betting sites in CO.

BetOnline Odds

Bets Available at the Best Sites for Sports Betting in Colorado

Each sportsbook provides its own selection of betting lines and will release these lines at different points (remember, BetOnline usually releases its lines early.) To make it easier to see which lines are available at what sportsbooks, we created the table below:
