The Colorado State Lottery was established in 1983, first issuing scratch tickets.

Distribution of tickets is via a network of retailers and vending machines. The Colorado Lottery also offers customers a lottery app, which enables players to check game results, scan tickets, join bonus draws, find retailers and play free games.
Often proceeds from state lottery’s would be directed to education and other public work infrastructure programs. In the state of Colorado, however, these funds are directed to the protection of the environment. Funds are used for environmental conservation, wildlife sustainability and growth.
A Lawyer’s Opinion
Another progressive state, Colorado’s gambling laws lead the way, with online gaming and gambling being unregulated and, thus, permitted, due in part to the few land-based casinos. This being noted, the state does lay claim to having the first casino in the United States, Brown’s Saloon, opening in 1822 to serve the miners seeking to increase their hauls.
In addition to the state’s liberal stance towards online gambling, race betting, off-track betting, pari-mutuel betting, social gambling, charitable gambling in the form of bingo, pull-tab games, and raffles, land-based casinos – both for-profit and Indian reservation run, and multi-state lotteries are all embraced. See Colo. Rev. Stat. § 18-10-101 et seq.; Colo. Rev. Stat. § 12-60-101 et seq.; Colo. Rev. Stat. § 12-47.1-101 et seq.
Sports Betting: Sports bookmaking, both land-based and online, including fantasy sports, is permitted in Colorado for residents aged twenty-one and above through licensed domestic and offshore platforms though no Colorado-based operators currently exist.
