⭐ Colorado Online Casinos Quick Facts

⭐ Are Online Casinos Legal in Colorado as of September 2025

Currently, there is no available real money online casino Colorado. You can place wagers on social and sweepstakes casinos or visit a land-based casino. Online sports betting became legal in May 2020 after voters approved it. The chances of a new gaming bill that will regulate online casinos in Colorado in 2025 look pretty slim.

Is There a Tax on Winnings at an Online Casino Colorado

Yes, there is a 4.4% state tax on gambling winnings, and you must declare any winnings on your income tax forms. There is also a 24% federal tax on winnings, which is charged by the casino. Once the first Colorado online casino gets a license, the same rates will likely apply.

Can I Bet on Sports in Colorado

Sure, as online gambling in Colorado is available on sportsbooks, the state chose to legalize sports betting in 2019 after state voters approved Proposition DD. Sites that offer online betting need to partner up with a land-based casino or a tribal casino to get a master license for a gambling site.

Because CO is a huge betting market, several sportsbooks have already entered the state and Colorado bettors can choose from over 25 options. These sportsbooks are regulated by the Colorado Division of Gaming and the Colorado Limited Gaming Control Commission. New users can get Colorado sports betting promos when they first sign up.

⭐ How We Rate the Best Colorado Online Casinos

As players ourselves, we emphasize factors that can make or break a good profit and overall gaming experience. Game variety, promos and offers, banking, mobile apps, and customer service are the main areas that go through our extensive testing process for the best Colorado online casinos.

Game lobby

Sweepstakes online casinos in Colorado offer all kinds of online casino games, ranging from video poker and table games to slots. These online casino games work just like they would in physical casinos or real money online casinos; you just won’t get any actual gambling winnings.

Instead, you can win cash prizes without risking your own money to play casino games. Some game types, like bingo and scratch cards, are also available on sweepstakes casinos but they are not as common as the games below.

✅ Online Slots: Slots are staple games on all social online casinos in Colorado. You can find classic slots, video-based slot games, and progressive jackpots. With your daily free coins, you can play any slot machine on the sites above.

On some sites, you can only play certain games first and more games are released as you progress through player levels. Playing slots online, both on desktop and mobile devices, is essentially the same as playing them at live casinos.

✅ Table games: Baccarat, blackjack, craps and roulette are gambling cornerstones, and you can play them for free on several social sites. Playing table games online is similar to playing in person, but you can take your time to learn to play if you are new to gambling or trying that specific casino game for the first time.

You can also find live games at an online casino Colorado, which is as close to an online casino gambling experience as you can get under the current regulations. Live dealer games have the interactive component software games are missing, which is the main reason why some players prefer these versions of table games.

✅ Video Poker: Finally, video poker games are very popular online as well. The most common variant in real-money casinos is Game King, but that’s not available on social sites. Regardless, there are plenty of video poker options at many of the casinos we recommend here.

Online poker for money is not legal in Colorado, but some social casinos let you play for free. If online poker sites are legalized, you will be able to play on World Series of Poker and other similar sites.
