Sports bettors seem to have it all in Colorado. Since the state legislature approved a sports betting ballot measure that CO voters approved in 2019, more than two dozen online sportsbooks have launched in the state. Bettors can now wager on their favorite sports markets online, via mobile device, or in one of CO’s more than 30 land-based casinos.
However, real-money online casinos are not yet legal in the Centennial State. Still, Colorado residents and visitors have plenty of sweepstakes and social casino options available. These free-to-play online casinos are a great alternative to real-money gambling.
Our experts are here to show you the Centennial State’s latest and greatest online casinos, so you don’t have to miss out on the iGaming fun. We have scoured the internet for the best online casinos in Colorado, using our years of experience reviewing and rating sweepstakes and social sites.

Our casino review experts have highlighted the most popular online casino games currently available in Colorado.
Real-money online casinos are not yet legal in Colorado. Elected officials have discussed regulated Colorado online casinos in recent years. Considering the state’s openness to legal sports betting, CO online casinos could become a reality.
To do so, the state legislature would need to pass an online casino bill, signed by the governor, before being issued to voters to approve on an ensuing ballot measure. Under a hypothetical bill, the state’s 30+ retail casinos could apply for licenses and partner with online casino operators afterward. Still, the earliest legal online casino gaming in Colorado could begin is in 2025.
Until then, you can still enjoy an online casino experience in the Centennial State. Social and sweepstakes casinos allow you to play all your favorite casino games from the world’s most famous software developers. These sites act basically the same as traditional real-money casinos online, except you don’t need to gamble with your actual cash. Instead, you can claim virtual currency promos or purchase coin packages and use them to play casino games.
Though the names of these virtual currencies vary from casino to casino, most are known as Gold Coins (GCs) and Sweeps Coins (SCs). While you can only purchase GCs, you can earn both GCs and SCs from promotions and bonuses. If you accumulate enough SCs, you can exchange them for real-life prizes. This is why sweepstakes casinos are legal in Colorado, as you don’t need to wager real cash to win rewards.
1948: Pari-mutuel wagering on horse and greyhound racing is authorized, and the Colorado Racing Commission was created. A decade on, CO changed the state constitution to allow charitable gaming, including bingo.

2009: Gaming limits increase to $100 per bet. In 2014, greyhound racing was made illegal.
2019: Legislation allowing each of Colorado’s 33 casinos to apply for online and retail sports betting licenses is passed. In May 2020, online sports betting launched.

If you wish to buy GC packages and top up your bankroll, you can choose from a selection of Colorado-friendly banking options. Our recommended sites accept purchases from Visa and Mastercard debit/credit cards, e-wallets like Skrill, Neteller, and PayPal, bank transfers, vouchers, prepaid cards, and even crypto.

Real-money online casino games are not yet legal in Colorado. However, you can still spin the reels of thrilling slots or try your hand at virtual table games for free at social and sweepstakes sites. You’ll find that the best sites feature a big selection of games from the best providers on the planet, like IGT, Red Tiger, Playtech, NetEnt, Play’n Go, and High 5 Games.
You can also completely customize your experience. Slot players can pick from a variety of themes – from titles based on popular films and TV shows to Ancient Egyptian games, retro virtual fruit machines, and everything in between. You can also select games with exciting mechanics and unique features like stacked wilds, free spins, and bonus games.
You can customize your experience even further by choosing a game based on Return To Player (RTP) percentage. The RTP gives you an idea of the amount of money you can expect to receive back during gameplay. For example, if a game has an RTP of 96%, which is the average RTP for online slots, you can expect to win back around $96 for every $100 you wager.
Remember that the RTP is calculated over hundreds and thousands of spins or rounds – it is only an average. Slots and other casino-style titles are games of chance, meaning you could walk away with a big win or a big loss.
