Our Top Five Recommended Colorado Casinos
Crown Coins
97.96%
RTP
We love playing sweeps games on the go, like many other players, so we’re pleased with Crown Coins and their fantastic iOS app experience! Hopefully, they can introduce an app for Android users soon, similar to McLuck. However, their mobile site is very user-friendly, so it isn’t too much of a drawback.
Their 650+ games offering may not be as big as the mammoth 3,000+ library at Stake, but with slots such as Buffalo King Megaways and Gates of Olympus available, players still have plenty of top-quality games to choose from.

Sweepstakes Expert
Pros
4.7/5 rated app on Trustpilot
1.2 million CC + 60 SC first purchase bonus compares generously to Lonestar bonus
More payment methods offered than RealPrize or Ace
Cons
650+ game library is smaller than competitors like NoLimitCoins, McLuck, and Jackpota
Limited live dealer options compared to Stake or Funrize
BigPirate
96.49%
RTP
Big Pirate only launched in December 2025, but is already making waves through the sweepstakes world! Their interactive games, including island building and player raids, make it an incredible user experience, giving you extra on top of their 1,600+ game library. New players can also enjoy 100,000 GC, 2 Diamonds, and 2 Rum Coins to get started. Even more can be claimed through daily bonuses, a refer-a-friend promotion, and monthly tournaments.
First-purchase offers also welcome new players with 150% extra, such as 250,000 GC, 25 Diamonds, and 1 Rum Coin for just $9.99. However, the purchase methods are more limited than at Casino.click, with no e-wallets or bank transfer options.

Pros
New sweeps casino means greater bonuses and promotions
1x wagering requirement for Diamonds currency
Seamless mobile experience despite the lack of an app
Live dealer casino has more variety than McLuck
Cons
Many slot games have low RTP figures
10,000 GC no deposit bonus is lower than Lonestar
No phone support option
Funrize
96.01%
RTP
Funrize is a great choice for Colorado players thanks to its large variety of bonuses and deep catalog of games. In addition to the sign-up bonus of 125,000 Tournament Coins (TC), Funrize has an extensive slate of existing player promotions to reward loyal players. You can score bonus TC and Promotions Entries (PE) via the Daily Wheel in addition to a 5% lossback offer thanks to the Daily PlayBack bonus.
The game library is extensive, with more than 1,200 titles available, including the latest games like Snoop Dogg Dollars. We like that Funrize offers games from trusted providers, like BetSoft and BGaming, ensuring that the quality remains high. While there are no RNG table games available, the range of live dealer games is impressive, with more than 35 games available.

Pros
No deposit bonus includes more TC (125,000) than Jackpota (7,500 GC)
Larger game library (1,200+) than LoneStar (500+)
Larger selection of live dealer games (35+) than Crown Coins
Cons
No deposit bonus doesn’t include any PE, unlike Crown Coins or Stake.us
No iOS or Android app available
Stake
96.59%
RTP
Stake.us is undoubtedly one of Colorado's most well-known sweepstakes casinos, thanks to its official partnerships with Drake and MMA champion Alexa Grasso. It’s not all flash, though. Stake.us makes our list thanks to its 3,000+ high-quality games, offering more variety than Crown Coins and RealPrize combined!
Although Stake is best known as a crypto-friendly site, it now accepts a broad range of traditional payment methods like debit and credit cards. However, Bitcoin and Ethereum redemptions are still some of the fastest in Colorado.

Sweepstakes Casino Expert
Pros
Crypto redemption methods pay out within 1 hour
iOS app available with 4.6 star rating from users
Market-leading game library including table games, live dealers, and exclusives
Cons
No phone support offered, unlike Ace, McLuck, and others
3x wagering requirement exceeds 1x requirement at most other competitors
McLuck
96%
RTP
With one of the largest libraries in the sweeps world, McLuck has plenty to offer for beginners and veterans alike. The 1,300+ games may feel overwhelming, but their desktop site offers filters, personalized recommendations, and a visually appealing interface. Looking for a Megaways slot or an Aztec theme? Simply filter them out and browse away!
Unfortunately, payment methods are limited to card payments, Apple Pay, and Google Pay. To improve, we’d like PayPal offered, as well as speedier redemptions for bank transfers, which can take up to five days.

Pros
McJackpot prizes with four progressive tiers
Super low gift card redemptions starting at 10 SC
App available for both iOS and Android, unlike most competitors
Cons
Smaller no deposit bonus than Stake, Lonestar, or Crown Coins

Top Legal Games to Play at Colorado Casinos
Just because there are no legal online casinos in Colorado doesn’t mean you can’t find places to play casino games in the Centennial State.
Best Casino Games to Win Real Money in Colorado
Colorado’s online casino market may be restricted compared to other states, but you can still find thousands of high-quality online casino games at sweeps sites in the Centennial State. See below for some of the most popular games you can play in Colorado.
How to Win Real Money on Casino Games in Colorado
Players may want to stick with games with high RTP percentages for greater potential chances of winning. RTP tells you how much a game will pay on average over time. For example, a game with a 98% RTP will pay out $0.98 for every $1 wagered.
Games with high RTPs payout more on average in the long run, however, all games use Random Number Generators (RNG), so no outcome is guaranteed. Most online slots range from 92%-99% RTP, while table games typically start at around 98%.
Colorado Online Gambling Overview
Colorado Gambling Law
Colorado has some of the richest gambling history in the US. Saloons and casinos were essential to the state's establishment during the Wild West period. More recently, Colorado's gambling laws have been a little more controlled. The state slowly legalized horse racing betting, charitable gambling, and lottery games before finally legalizing land-based casinos in 1990.
In 2019, Colorado officially legalized some forms of online gambling by passing Proposition DD to legalize online and in-person sports betting. Over a dozen legal online sports betting sites are now available in Colorado, but online casinos remain illegal.
Former Department of Revenue Executive Director Mark Ferrandino said in 2023 that there was some movement to legalize Colorado online casinos in the state legislature. However, it is currently unclear whether state lawmakers are actively planning to expand the state’s legal online gambling market.
How to Play With Colorado Casinos
Getting started with Colorado sweepstakes casinos is a straightforward process that shouldn’t take longer than a few minutes. Follow this step-by-step guide and see how easy it is to start playing casino games in Colorado today:
- Pick your casino: Use this guide and our other Colorado casino resources to pick a site you will enjoy. Any links on this page will take you directly to its website.
- Create your account: Select “Sign Up” or “Join Now” and fill out the sweepstakes casino registration form with your name, email, and other personal information.
- Claim a bonus: Most Colorado sweepstakes casinos will reward you with GC and SC for registering.
- Verify your identity: Upload a picture of your government ID (driver’s license, passport, etc.) to verify your identity and gain full access to your account.
Accepted Colorado Online Casino Banking Methods
After you create your account, your sweeps site should boost your virtual bankroll with free coins.
You'll need to buy a bundle when you want to top up your GC and SC. Review the available packages and assess whether or not you wish to buy. Remember that your first purchase will usually be discounted as part of the welcome bonus offer, but this discount will not last forever.
If you buy coins in addition to your sign-up package, you will have many payment methods available. All the top online casinos in Colorado accept traditional banking methods like Visa and Mastercard and modern options like Bitcoin.

Who Can Play at Colorado Online Casinos?
Anyone 21 or older can legally play at land-based casinos and bet on sports in Colorado. You must also be physically in the state to use licensed Colorado sports betting sites. This means you must allow the gaming operators to use your device’s location to verify where you are before you start playing.
However, sweepstakes casinos in Colorado can vary between being open to players over 18 or over 21, depending on the brand’s internal policies.
What Legal Requirements Must Players Meet for Colorado Casinos?
Before you can win whilst playing casino games or betting on sports in Colorado, you must verify your identity. Most sites make this easy and will automatically use the information you used to sign up to verify your identity. Social casinos typically ask you to provide a picture of an official government ID, such as your driver’s license or passport.
Who Regulates Online Casinos in Colorado?
All online gambling in Colorado is regulated by the Colorado Limited Gaming Control Commission (CLGCC), a five-member sub-agency of the Department of Revenue, Division of Gaming. Colorado online casinos, offshore casino sites operating in Colorado, and legal online sportsbooks all fall under the CLGCC’s jurisdiction.
Their main goal is to protect players. They ensure that legal gaming operators follow state law and that no unlicensed sites operate in the state to rip players off. The CLGCC also provides responsible gambling resources and other valuable tools for Colorado players.
What to avoid
It’s important to understand that not all casinos you can play online are safe. There are many unsafe casinos that don’t have the same player protections from the ones we recommend.

Legal vs Offshore Casinos in Colorado: What’s the Difference?
When we say legal online casinos, we are talking about casino sites that have received licenses from the state government to operate legally inside the state. Colorado has not legalized online casinos, so the state has not issued any licenses.
Offshore casinos, on the other hand, are online casinos based abroad. They typically have licenses from international jurisdictions like the Malta Gaming Authority, but some operate outright without licenses.
International online casinos are technically available in the US, but many states, including Colorado, have started to crack down on them. We suggest sticking with trustworthy US casinos and sweepstakes sites versus offshore casinos.
Land-based Casinos in Colorado
There are plenty of great land-based casinos to choose from. With the help of the Colorado Department of Revenue’s Division of Gaming, the mountain cities of Black Hawk, Central City, and Cripple Creek have developed into booming casino hubs. There are plenty of casinos in the state, with 20 of our top picks listed below.
Ameristar Casino Resort and Spa
With over 830 slots and a massive 57,000-square-foot gaming floor, the Ameristar Casino Resort Spa in Black Hawk is one of the biggest casinos in Colorado. It also has one of the state’s largest selections of table games and poker tables, with 25 blackjack tables, roulette, table games, and 11 poker tables.
Monarch Casino Resort Spa Black Hawk
Formerly known as the Riviera Casino, the Monarch Casino Resort Spa is arguably the most popular casino in Colorado. Part of its popularity is due to its proximity to Denver. This isn’t the only reason, though. Monarch Casino has a vast 250-seat buffet, four other restaurants, multiple bars, and even lounges to complement its selection of over 1,100 slots and 50+ tables.
Dragon Tiger Casino
Formerly know as Johnny Z’s before rebranding in 2022. This casino may not be as big as the Monarch or Ameristar Casinos, however a 2024 study called it the “luckiest casino in Colorado.” Based on player data and reviews, the study gave Dragon Tiger Casino a 28% “luck percentage.” Monarch and Ameristar both scored under 15%.
In addition to this lucky study, Dragon Tiger Casino boasts over 200 slots as well as a few classic table game favorites.
