Colorado online sports betting and gambling is available in the Centennial State through both state-regulated and offshore sites.
But when it comes to getting all your Colorado gambling needs on one platform, then there really is only one option. This guide will show you where to find everything you need from casino gaming to sports betting and where the best bonuses are.
4 of the Best Colorado Online Sports Betting Sites
As you can see from the list above, there are lots of options for you to choose from. But in this guide we’ll focus mainly on Colorado online sports betting sites. Why? Because all of our recommendations also feature Colorado online casinos which you can feel free to check out.
Like we said, it’s everything you need all on one platform – something that state-licensed sites simply cannot offer. And here are four of our absolute favorites.
1. BetOnline – The Complete Colorado Online Gambling Site
Payout time: 1-2 days
Established: 2012
License: Panama Gaming Commission
Available in Colorado: Yes
Pros
>35+ sports and superb odds and lines
Multiple welcome bonuses available
Excellent selection of 500+ slots
Among the best online poker products
Cons
Card payments have fees
The site could be snappier
BetOnline is one of, if not the best Colorado online gambling site. It has everything from great casino games through to excellent poker software. And when it comes to sports betting, you’ve got a massive range of markets including esports and entertainment.
BetOnline is known for its early betting lines. But they’re not just the earliest, they’re also massively competitive with lots of boosts on select markets.
For banking, you’ve got the complete range of methods, but we have to say that the crypto options are best. These are super fast with some payouts processed instantly depending on which coin you use.
2. TG.Casino – Top Colorado Online Gambling Site for Crypto
Payout time: 0-2 days
Established: 2023
License: Curacao eGaming License
Available in Colorado: Yes
Pros
30+ sports to bet on
More than 5,000 casino games
Near instant payouts
Buy crypto through the site
Cons
No direct card deposits
TG.Casino is a recently launched Colorado online gambling site that has quickly become the go-to sportsbook for crypto users. That’s right, despite its name, this site has a fully fledged sportsbook with competitive odds.
TG.Casino covers a wide range of sports with over 30 categories and a massive number of markets for each. The site has also recently partnered with legendary Italian soccer team AC Milan.
We’d like to see a few more promos at TG.Casino that go a little further than the airdrops and contests currently available. On the banking side of things, this crypto-exclusive site is one of the fastest payout sites and also offers the option to buy crypto using a card.
200% Welcome Bonus up to 10 ETH
Official Partner
AC Milan
200% Welcome Bonus up to 10 ETH
Generous 10 ETH bonus and high roller NFTs
Trusted by Web3 influencers and powered by $TGC token
World’s first licensed telegram sportsbook – fully anonymous
BetUS is one of the best known Colorado gambling brands and has been in operation across the US for three decades. Here you’ll find a full sportsbook, casino, and racebook. And yes, the odds are pretty good for sports.
BetUS has an incredible range of resources for bettors which includes lots of picks for specific sports betting markets through BetUS TV. Perfect for the right tips.
One thing we’re not overly keen on is the sportsbook layout which doesn’t show you the games available right off the bat. Instead you need to choose a league or contest first. A minor drawback but one that could be improved.
125% Sign-Up Bonus:100% up to $2,000 on sport and 25% on Casino
125% Sign-Up Bonus:100% up to $2,000 on sport and 25% on Casino
Receive your earnings quickly, often within 24 hours
4. BetNow – Lots of Colorado Online Sports Betting Promos
Payout time: 24 hours
Established: 2015
License: Curacao
Available in Colorado: Yes
Pros
Great bonuses and promos

Excellent customer support
Cons
Not many niche sports available
BetNow is a good all-round Colorado sportsbook with everything you need including a full casino area. There’s a good range of sports to bet on from the English Premier League, NBA, and NFL to the UFC and Formula 1.
The odds at BetNow are competitive and the software behind the live betting feature makes everything run smoothly. Although outdated, the design of BetNow means navigation is easy, which is pretty good for beginners.
There are some great promos that run regularly and lots of focus on major events like the World Series or the Super Bowl. When it comes to banking, BetNow impresses with good support for both card and crypto payments.
Yes, Colorado online sports betting is legal as is daily fantasy sports (DFS). Casino gaming has yet to be legislated for at state level.
The only casino platforms currently available in the Centennial State are those that are part of the best Colorado sportsbooks we recommend above. These sites are licensed by international gaming authorities and are not subject to state laws.
They are also the only platforms to offer the complete Colorado online gambling and sports betting experience.
Colorado Online Gambling Timeline
May 2020: Colorado sports betting sites launch with four online sportsbooks going live.
Mar 2020: The Colorado Division of Gaming awards the first sports betting licenses to casinos and online operators.
Nov 2019: Colorado voters approve Proposition DD, legalizing Colorado sports betting sites and retails sportsbooks. The proposition passes with 51.41% of the vote.

Who Can Gamble Online in Colorado?
Depending on the Colorado sportsbook you go with, you may be able to gamble at either age 18 or 21. As a rule of thumb, anyone over 21 in Colorado can certainly play at the sites we recommend.
There are no further restrictions other than whatever may be in place with regards to proof of residency/identity.
For US-regulated Colorado online gambling options, the scenario is a bit different. You must be at least 21 to gamble online at US-regulated operators and need to provide various personal identification details. In addition, you must be physically located in Colorado any time you wish to place a bet.

A second chance bet offers players bonus bets up to the value of a bet if that wager is unsuccessful. Any profits made from the bonus bets can be withdrawn as cash, subject to terms and conditions.

Colorado Online Gambling Payment Methods
All Colorado online sports betting and gambling sites will offer at least 2-3 payment methods for both deposits and withdrawals. Here are the most common.
Bank Cards: Debit and credit cards are almost always accepted for deposits, but they are not available for withdrawals.
Wire Transfer: Wire transfers are secure, but they have high fees and are extremely slow.
Prepaid Cards: Prepaid cards are exactly like debit cards preloaded with cash. These are available at some sites but not all and they do not support withdrawal.
Cryptocurrencies: Secure payments with digital coins like BTC and ETH. This the fastest and cheapest option.
E-Wallets: E-Wallets like PayPal and Skrill are rarely accepted by offshore sportsbooks.
Taxes on Colorado Online Gambling Winnings
Colorado classes all gambling winnings as taxable income. This means that you will need to pay both state and federal taxes on any winnings at a regulated sportsbook. They will withhold taxes over a certain threshold and issue you with a W-2G form. This is a legal requirement by US law.
But offshore Colorado online gambling sites don’t fall under the same legal requirements. This means that they will not notify the IRS of your winnings. It’s your responsibility to do so.
Colorado Gambling Apps and Mobile Sites
Most of the offshore Colorado online gambling sites that we recommend do not have native gambling apps like their US-regulated counterparts. Instead, they have designed their sites to work flawlessly on mobile browsers.
What this means is that you get all of the same features and functions on your Android or iOS device without having to download an app.
Gambling Locations in Colorado
The Colorado gambling industry is stacked with land-based sportsbooks. These are all located in the state’s licensed casinos with the casino operator holding the master license and partnering with a sports betting operator.

How Colorado Gambling Compares to Neighboring States
Colorado has a great online sports betting industry and a land-based industry that features casinos and retail sports betting. But what about its neighboring states?
In Arizona, you can gamble online via US-regulated sportsbooks, but online casinos regulated by the state are not yet permitted. Luckily, the Arizona online gambling industry also features offshore sites.
Sports and online casino gambling are not yet legal in New Mexico via US-regulated entities. This is where the leading offshore operators become your best options for New Mexico gambling.
Utah has strict rules regarding gambling of any kind, and this is unlikely to ever change. Yet, you can freely and safely play on the leading offshore sportsbooks and Utah online casinos we recommend.
In Oklahoma, US-regulated online sportsbooks and casinos are not yet a reality. This is where the leading Oklahoma online gambling sites promoted here come into their own.
While US-regulated sportsbooks in Kansas are available, online casino gaming is still not regulated in the state. Just as with the other states on this list, our Kansas online gambling recommendations offer a better alternative.
In Nebraska, sports betting and casino gaming via US-regulated online gambling sites is not legal. We recommend playing at the best Nebraska online casinos based offshore.
You can wager on regulated Wyoming US sportsbooks, while casino gaming online is still not regulated in the state. But once again, the best offshore Wyoming online gambling sites are easily accessible from within the state.
Responsible Gambling in Colorado
Like many states, Colorado offers comprehensive responsible gambling services for problem gamblers. The Problem Gambling Coalition of Colorado (PGCC) works with the Colorado Gaming Association to offer players a self-exclusion program.
Adding yourself to this list means you’ll be removed from all casino marketing lists, cancel your membership at the state’s casinos, and be prevented from depositing at any Colorado casino. Unlike many states, adding yourself to the CO self-exclusion list is not a temporary measure but a permanent ban.
While operating under international jurisdiction, the offshore Colorado online sports betting and casino gaming sites we promote also take responsible gambling seriously. You’ll find helpful resources to help you control your gambling via all of these reputable offshore gambling operators.
The third-party organizations listed below offer support for anyone experiencing the harms of problem gambling.
