Are Online Casinos Legal in Colorado?

Colorado online casino sites operated by US-regulated providers are not yet legal, but residents still have access to online gambling options. The Centennial State currently permits land-based commercial and tribal casinos, mobile and retail sports betting, and the state lottery. However, online casino gaming has not been licensed at the state level.

Despite this, players in Colorado can legally access real-money online casinos based outside the US. These sites are regulated by established international gambling authorities and welcome players from Colorado. It’s important to note that a few popular platforms, like Bovada, do restrict access for Colorado residents, so always check availability before signing up.

Recent CO Online Gambling Legislation Changes

There haven’t been many significant legislative efforts to change the status of legal Colorado online gambling. Since 2018, the state has focused solely on legalizing sports betting. Colorado’s Constitution requires voter approval to legalize online casinos, but no relevant bills have been proposed.

Here’s a brief overview of Colorado’s legislative milestones and recent changes to the state’s gambling laws:

• 2018: The US Supreme Court strikes down PASPA, permitting every state to regulate its sports betting market.
• 2019: Colorado lawmakers sign HB1327 into law, legalizing sports betting in the state. Voters also approved Proposition DD later in the year, launching mobile sports wagering as well.
• 2020: Colorado’s first legal sportsbook goes live, regulated by the Colorado Division of Gaming and the Colorado Department of Revenue.
• 2024: Online casino and poker are still illegal as lawmakers focus on expanding the state’s sports betting market.
• 2025: Colorado online casino legislation gains no momentum. There are still no active bills or efforts to legalize Colorado online casino sites.

Will Colorado Ever Legalize Online Casinos?

Although the process of legalizing Colorado online casinos has gained no momentum, there are indicators that the laws may change. While several hurdles can significantly delay legalization, there are also factors supporting the launch of Colorado online casino sites.

The success of sports betting in the state, which has generated millions in revenue, will likely push lawmakers to consider legal online casinos. Legalizing online casinos in Colorado would require voter approval via referendum, and no bills have been introduced recently. However, growing public interest and potential for millions in tax revenue are both factors that could push lawmakers to consider online casinos in upcoming legislative sessions.

How Do the Gambling Laws in Colorado Compare with Neighboring States?

Colorado has relatively progressive gambling laws compared to many US states, including its bordering states. The state has commercial casinos, retail and mobile sports wagering, and a Colorado state lottery, giving residents plenty of opportunities for legal gambling.

Colorado shares a border with seven states, including Utah, which has a complete ban on all forms of gambling. Other neighboring states have similar or more progressive laws.

The table below provides a quick overview of the gambling laws in Colorado’s neighboring states.

Can You Play at Online Casinos in Colorado?

As of 2025, Colorado residents can only legally play at an online casino through offshore casino sites. There are various trusted online casinos, like Raging Bull and Wild Casinos, which are licensed by reputable gambling authorities outside the US and accept players from Colorado. These sites are popular alternatives in states where online casinos are still illegal, but they’re also the go-to option in states with regulated online casinos.

Unlike most state-regulated online casinos, offshore sites operate with fewer restrictions, offering better game options, bigger bonuses, and more payment flexibility. Many have also been around much longer than US-licensed operators. For instance, Raging Bull, BetNow, and BetUS have been operational for over a decade, establishing a solid reputation among US players. The international casinos recommended on this page are tried-and-tested brands we’ve worked with for several years, offering high-quality games and swift payments. More importantly, they pose no legal risks for Colorado residents.
