Are Online Casinos Legal in Colorado?
To answer some common questions, such as “Is online betting legal in Colorado?” or “Can you bet online in Colorado?” here is the answer.
Internet gambling with US-based online casinos in Colorado remains illegal. The Colorado Gambling Commission oversees legal gambling on the state lottery, organized horse racing, bingo, raffles, and charity games, and finally, social gambling, which is explained in this news release made in 2005.
Although online casino gambling is not yet legal, sports betting was legalized in May 2020. However, for casino fans, the sites covered in our guide are licensed and regulated outside of the US; therefore, they avoid these restrictions, making them safe casinos to play at and secure for casino-style gambling in Colorado.

BetWhale Casino offers one of the most generous welcome bonuses in the industry with a 250% deposit match worth up to $2,500. Those all-important bonus funds can be used to play any of the 1,500+ casino games (although not all will contribute to your rollover requirement).
The chunky welcome bonus is supplemented by a range of regular promotions like no-deposit bonuses, weekly reload bonuses, and free spin bundles.
Top game providers like Visionary iGaming, Fresh Deck Studios, and BetGames.TV powers the 70+ live dealer games that are played 24/7 every day of the year. As well as popular game varieties like Blackjack and Roulette, you can also enjoy specialty tables such as Dice Duel, Football Grid, Classic Wheel, War of Bets, and Wheel of Fortune.

Table and progressive jackpot games are also available in small numbers.
When you register for a Raging Bull account, you’re eligible to receive a 250% first deposit match up to $2,500. This offer also unlocks 250 free spins on the popular Mighty Drums slot, while it’s accessible simply by depositing $10 or more and using the unique promo code MIGHTY250.
This promotion has a relatively low rollover requirement of just 10x your combined deposit and bonuses, too (for fiat users).

Slots of Vegas offers a small selection of specialty games, too. These include a popular Keno variant, alongside provably fair, crash-style games such as Galaxy Blast and Ripcord Rush.

This unlocks several daily and weekly reload bonuses, some of which match your qualifying deposit by up to 300%. There are even late-night reloads based on the amount that you deposited during the previous 24 hours.

How Colorado Online Casinos Compare to Neighboring States

Legal Status for Casino Wagering in States Local to Colorado
Choose state
Kansas is home to four state-owned commercial casinos, which are developed and operated by private entities. These casinos provide a variety of gaming options, including electronic gaming devices, table games, and sports betting. They function under the constitutional oversight of the Kansas Lottery and are subject to regulation by the Kansas Racing and Gaming Commission (KRGC).
In 2007, the Kansas Expanded Lottery Act was passed, paving the way for the establishment of four “lottery gaming facilities,” each located in one of the state’s four designated gaming zones. These Kansas casinos commenced operations between 2009 and 2017.
By 2022, new legislation permitted Kansas’ commercial casinos to offer sports betting as well.
Nebraska hosts commercial casino gaming at three temporary racino venues, where patrons can enjoy electronic gaming devices, table games, and sports betting. Additionally, sports betting is available at a fourth racetrack site.
In 2020, Nebraska voters passed a constitutional amendment permitting commercial casino gaming at licensed racetracks. Following this, state legislators enacted a bill in 2021 to put the voter-approved measure into effect, allowing sports betting to be conducted at racinos along with traditional electronic gaming and table games. The state’s initial racinos began their operations in 2022. Oversight and regulation of casino gaming in Nebraska are managed by the Nebraska Racing and Gaming Commission.
New Mexico features commercial casino gaming across five racinos. The authorization for electronic gaming devices at licensed racetracks was established by a state law in 1997, and these activities are overseen by the New Mexico Gaming Control Board.
While there is no legal cap on the number of racinos that can operate in New Mexico, current agreements with federally-recognized tribes limit the number to six commercial racinos. These racinos can host up to 750 electronic gaming devices but are not permitted to offer table games. Unique among states, New Mexico casinos have specific limitations on the operating hours for all commercial casino venues. Electronic gaming devices at racetracks are only operational on days with live or simulcast horse racing, for a maximum of 18 hours each day, and cannot exceed 112 hours of operation in any given week.
Being a Mormon state, any legislation surrounding betting and gambling, either on sports or casinos, is very much taboo. This situation is not expected to change anytime soon. There are currently no state-based online casinos available to residents in Utah.
Wyoming does not have real money online casinos, but it does provide mobile sports betting services through four commercial sportsbook operators, all of which are regulated by the Wyoming Gaming Commission. Additionally, sports betting options are accessible at tribal casinos.
In April 2021, legislation was enacted that empowered Wyoming’s gaming and racing authority to grant licenses for online sports betting to operators already licensed in a minimum of three other states. This paved the way for the launch of online sports betting in September 2021.
