Colorado legalized sports betting in 2021 but still has not legalized online casinos. However, the state does have two options to play for real money, both of which operate under a partnership with a tribal casino. This system is likely to be a precursor to future online casino legalization in the state. Until then, residents can visit the Mohegan Sun and DraftKings sportsbooks to place their bets. The latter have already launched their own sportsbooks in Wyoming, which could help lead the way to legalizing online casinos in the state.
