    Gambling Laws In Colorado

    Lawbook

    While Colorado has allowed several forms of gambling, online casino gaming is not regulated or even addressed by the state. Nonetheless, it is illegal to operate an online casino site based in Colorado until proper legislation has passed and the online provider has received a license from the state.

    However, the state does not discourage players from enjoying online casinos, sportsbooks, and poker rooms, and domestic online sports betting is now legal within CO borders. That said, you'll almost always find more valuable betting odds with overseas providers rather than local domestic sportsbooks.

    Is Online Gambling Legal In Colorado?

    State-regulated online casino gambling has not yet come to Colorado via legislative effort, though mobile sportsbooks are allowed. CO online sportsbooks formally launched on May 1, 2020.

    However, casinos, sports betting, and playing poker online at offshore sites is not illegal because no state laws exist that specifically prohibit CO players from engaging with these platforms. In addition, the current structure of US law does not prohibit individuals from using these legitimate international betting sites.

    Are Colorado Casinos Legal?

    casino iconColorado allows land-based casinos to its residents and state visitors. However, the state has not moved on to legalize state-regulated online casinos. Local options include, but are not limited to, the following venues:

    • Sky Ute Casino
    • Ute Mountain Casino
    • Ameristar Casino & Resort
    • Isle Casino

    These casinos offer poker, table games, and other card games. However, the minimum age to play at these venues is 21. This leaves out a whole market of 18+ CO players, which is why we recommend CO residents and visitors use legitimate offshore online casinos, as they accept players as young as eighteen.

    Are Online Casinos Legal In Colorado?

    While online casinos are not sanctioned at the state level, it is considered entirely lawful for CO players to participate on online casinos so long as they are operating legally offshore. This is because the state does not have any laws which explicitly prohibit domestic access to these sites. This is also true for US federal laws which do not directly mention legal international online gambling.

Social poker is also permitted when played in compliance with state regulations (i.e., the private host venue may not take a rake of the pot). However, the state has yet to authorize online poker.
