Gambling Age in Colorado

The legal gambling age in Colorado is 21 for casino gaming and 18 for lottery tickets and other forms of charitable gaming. Colorado’s gambling landscape includes both mountain casinos and statewide sports betting options, attracting locals and visitors alike.

You Must Be 21 to Gamble in Colorado

To gamble at casinos in Colorado, you must be 21. These casinos are located in three historic towns—Black Hawk, Central City, and Cripple Creek—and offer slot machines, table games, poker, and sports betting. However, the legal gambling age for purchasing lottery tickets or participating in charitable bingo and raffles is 18.

Colorado’s gambling history began in 1990, when voters approved limited-stakes casino gambling in the three mountain towns to revive their economies. The industry has since expanded, including online and retail sports betting following a successful 2019 ballot initiative. Despite this growth, strict age limits remain in place to ensure responsible gambling and compliance with state regulations.
