Legal Information About Online Gambling 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.

History of Gambling in Colorado

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.

1990: Limited gaming in Black Hawk, Central City, and Cripple Creek were authorized. A year later, maximum bets in Colorado casinos were initially limited to $5, with a ban on 24/7 opening hours. Multistate lotteries were later legalized.

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.

Land-Based Casino in Colorado

Colorado is home to almost forty casinos. The state’s commercial casinos are in three small towns in the mountains. There are also several Native American tribal gaming centers.

The biggest brick-and-mortar casino in CO is Ameristar Casino – spanning over 150,000 square feet.

You can also visit two tribal casinos in the southwestern sphere of the state – Ute Mountain Casino and Sky Ute Casino.

Colorado Sports Betting

Legal online sports betting launched in May 2020. Roughly two dozen online sportsbooks have entered the market, though several have since folded. There are 20 live books as of late 2023.

Colorado sportsbooks offer a wide range of sports and bet types. Table tennis betting is especially popular in Colorado.

Other Types of Gambling in Colorado

Almost forty land-based and two tribal casinos are active in CO, so there are plenty of in-person betting options.

Charitable gaming, bingo, raffles, and lottery games are also legal. That is in addition to the myriad social and sweepstakes online casinos permitted in Colorado.

Future of Gambling in Colorado

The CO sports betting market launched has grown to be one of the most successful per capita online sports gambling markets in the US. This has sparked legislative and citizen interest in real money online casinos, though the earliest launch would be early 2025.

Until then, you can enjoy many social and sweepstakes online casinos in CO.

Colorado Online Casino Payment Methods

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.

To exchange SCs for rewards, you may have to verify your identity and address before redeeming your casino credit. Generally, you’ll find that a scanned copy of your driver’s license, bank statement, or mobile bill will do the trick.

Best Real Money Casino Games in Colorado

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.
