More than 30 casinos across three historic mining towns. Over $6 billion wagered on sports in a single year. A gaming scene that started in the mountains and moved onto your phone. Here is where, how and what you can legally gamble on in Colorado.
Gambling Options Available to You in Colorado
Colorado offers a full slate of legal options, with one clear line: casinos live in the mountains, and online casino play is not yet on the table.
Online Sports Betting
Legal online and retail since May 1, 2020, after voters passed Proposition DD. Coloradans wagered a record 6.3 billion dollars in fiscal year 2025. A large operator field competes statewide. You must be 21 or older to bet.
Mountain-Town Casinos
Casino gaming is legal only in Black Hawk, Central City and Cripple Creek, plus two tribal casinos in the southwest. Expect slots, table games and poker across more than 30 venues.
Daily Fantasy Sports
DFS is legal and regulated in Colorado as a skill-based game. Major operators run full contests across the main pro and college sports.
Prediction Markets
Platforms like Kalshi let Colorado players trade on real-world outcomes such as sports results and economic data under federal CFTC oversight rather than state gambling law.
Horse Racing
Colorado has a long pari-mutuel tradition, with live and simulcast wagering at Arapahoe Park and advance deposit wagering platforms available online.
Colorado Lottery
Running since 1983, the Colorado Lottery funds parks, trails and open space through Great Outdoors Colorado. Scratch games, Powerball and Mega Millions are all available. Minimum age is 18.
Social Casinos
Social casinos let you play slots, blackjack, roulette and poker completely free, with no real money involved. A popular way to enjoy casino games in Colorado without any financial stakes.
Online Casinos
There are no legal online casinos in Colorado. Real-money iGaming has not been authorized by the legislature, so any site offering real-money online casino play to Colorado residents is operating outside state law.
