Are Real Money Online Casinos Legal in Colorado?

No, real-money online casinos are not legal in Colorado. Such sites are not on the list of allowed gambling options in The Centennial State. Additionally, casino operators licensed in Colorado cannot run online gaming sites.

Here’s a specific citation from the Colorado Department of Revenue

The Colorado Limited Gaming Control Commission prohibits persons and businesses licensed in the casino industry in Colorado from having any involvement with internet gaming sites that can be accessed by Colorado residents.

However, while you can’t play at a real money online casino Colorado, sweepstakes gaming sites provide a worthwhile alternative. 

Our Top 5 Sweepstakes Online Casinos in Colorado

At sweepstakes casinos, you play with free coins and not real money. That’s why the platforms are legal — not only in Colorado but across many US states. You can check out this extensive list of the best sweepstakes online casinos in the US, but here’s a rundown of our top 5 in Colorado:

WOW Vegas Casino in Colorado

First, here is WOW Vegas, a popular sweepstakes casino for slot gaming. With 1,000+ games, it’s easy to recognize why it’s a top contender for the best online casino Colorado players can use. Interestingly, the slots cut across different variants, including classics, jackpots, Hold and Win, Megaways, and more. Plus, the platform has a mobile app for smooth gaming on the go. 

When I signed up with WOW Vegas, I received 250,000 WOW Coins and 5 Sweepstakes Coins from the welcome bonus. No initial purchase was required.

With the free coins, I had fun spinning many slot reels, but my top favorite is Rocket Blast Megaways by Pragmatic Play. I found the game exciting due to the free spins bonus rounds — you can get up to 35 by hitting 9 or more scatter symbols. 

Fortune Coins in Colorado

At Fortune Coins Casino, you get access to a vast collection of exciting slots and fish games. The best part is that each one comes from a renowned provider. Additionally, there are also exclusive in-house titles you won’t find on other sites. 

Upon creating my Fortune Coins account, the sweepstakes casino gave me 630,000 Gold Coins and 1,000 Fortune Coins to start gaming for free. In my opinion, it’s one of the best Colorado online casino bonus offers at sweepstakes gaming sites. Switching to the game lobby, my best slot was Hot777, an in-house title.

The game is relatively simple to play with a classic reel structure and low volatility. But what I found most impressive is the commendable 1,000x maximum win.  

High 5 Casino in Colorado

If you’re looking for a Colorado online casino where you can play live dealer games, High 5 is a top pick. It’s one of the few sweepstakes casinos with real-time table titles, including blackjack, roulette, and poker. Impressively, High 5 Casino is still home to 1,200 slots.

At High 5 Casino, I didn’t have to make any initial payment to start playing games. As a legal sweepstakes gaming site, I received a welcome bonus of 250 Gold Coins, 5 Sweeps Coins, and 600 Diamonds.

If you’re curious about my preferred game at the site, I’ll go with Limitless Blackjack. That’s because the live table games allowed me to play with a minimal amount of Gold Coins, as there were no minimum or maximum limits. 

Golden Hearts Games in Colorado

At number four, you can go for Golden Hearts Games, a unique charity-based sweepstakes gaming. Due to its focus on charity, Golden Hearts Games is the only sweepstakes casino allowed to operate in all 50 US states. That’s one reason the platform gets high ratings, but the diverse collection of slots machines, Bingo, and video poker games is also a big plus. 

I must mention that Golden Hearts Games has one of the most rewarding welcome offers, with 250,000 Gold Coins and 500 Sweeps Coins. While testing the site, I recorded my best session with Bamboo Wilds, a relatively new slot from Booming Games.

Among the game’s many exciting features, the wild symbols with multipliers made gameplay thrilling.  

Sweeptastic Casino in Colorado

If you’re wondering why Sweeptastic ranks among the top Colorado online casino site, the answer lies in the game collection. On the site, you get engaging slots and exclusive original arcade games. Notably, the latter category included options like Crash, Plinko, and Dice games. 

The Sweeptastic welcome bonus rewards up to 30,000 Lucky Coins and 4 Sweeps Coins, which I found more than enough for free gaming. My best game at the social casino is SpaceXY, a crash title with a massive 10,000x multiplier. I played with 100 Lucky Coins, and my highest win was a 5.5x multiplier, meaning I got 550 Lucky Coins. 

Want to Bet Real Money? Try Land-Based Casinos in Colorado

As stated earlier, Colorado doesn’t permit real money online casinos. If you don’t want to play at sweepstakes sites, the only alternative is visiting physical casinos. The good thing is that Colorado law allows gambling at land-based locations, although the available options are limited.

Below are the best physical casinos you can visit in Colorado.

Ameristar Black Hawk in Black Hawk

This casino is located in a 4-star hotel in Black Hawk, with many premium facilities that make it worth visiting. You’ll find all the top games, including slots, table games, and video poker.

Bronco Billy’s Casino in Cripple Creek

Open 24/7, Bronco Billy’s provides a gambling location for slots, jackpot, and table games. However, what truly makes this land-based casino is the staff — particularly Christine, one of the hosts. Besides the incredible hosts, it’s worth mentioning that Bronco Billy has an exceptional dining section.  

As one satisfied player puts it,

The hosts are really there for the customers, especially Christine, who is an asset to the company and shows what a host is supposed to be like.

Ute Mountain launched in 1992 – 30+ years ago — as the first tribal land-based casino in Colorado.

You’ll appreciate the Bingo games if you love challenges.

How to Declare Taxable Winnings in Colorado?

Colorado online casino and land-based gambling winnings are classified as taxable income. So, you’ll have to pay the 4.40% income tax rate to the Internal Revenue Service (IRS) each time you make profits from gambling.

For instance: If you win $100, you’ll have to pay $4.40 as tax.

Usually, the casino operator will automatically deduct the tax when paying out the winnings. Hence, you won’t have to take any action yourself.

However, if the win is up to a certain threshold, you have to file Form W-2G with the IRS. Specifically, you’ll file the form if you win $1,200 or more in slots or bingo and up to $5,000 in poker tournaments. For other forms of casino gambling, you’ll file the form if your win is up to $600.

Other Legal Gambling Activities in Colorado

If you’re asking, “Is online casino legal in Colorado?” We’ve established that you can only legally play at sweepstakes sites and land-based locations. However, there are other forms of gambling permitted in Colorado which you may find interesting. These include lottery and horse racing events: 

  • For lottery games, you can legally participate in the Colorado State Lottery, with multiple prizes ranging from $100 to $500.
  • On the other hand, if you prefer gambling on horse racing events, you’ll have to use platforms licensed by the Colorado Racing Commission. 

History of Gambling in Colorado

The state of Colorado online casino legality today is negative, as the activity isn’t permitted. Additionally, there are only a few land-based casino houses. This reflects just how the legality of gambling in Colorado has changed over the years.

What’s Next for Colorado Online Casinos?

Since Colorado legalized sports betting in 2020, online sportsbooks and gambling have been on a steady rise. The activity is now prevalent, so much so that voters are considering gambling revenue to fund critical legislative bids like water conservation and protection projects. 

In the words of Senator Dylan Roberts, attorney of the Colorado General Assembly:

Now, we’re giving Colorado voters an opportunity to join in the fight and allow sports betting revenue to fund critical water projects that will benefit communities across our state.  

However, regarding Colorado online casino sites, there’s no definitive insight on whether they’ll be legal anytime soon. Nevertheless, according to the former Department of Revenue Executive Director Mark Ferrandino, there are ongoing discussions about legalizing online casino gaming in the state.

The director made the revelation in 2023 while speaking at the National Conference of State Legislatures (NCGLS) in Denver. Whether the outcome will be positive depends entirely on the voters.
