1. Spree - Best online casino Colorado for RTP percentage
Spree casino overview
Spree casino video review
Summary
Spree Casino is one of the newest sites on the sweepstakes block, opening in 2024 from Play Spree Ltd.
The site boasts more than 850 sweepstakes games, including slots and live dealer options. This diverse offering appeals to many sweepstakes slots fans.
New players start with 1,000,000 Gold Coins and 2.5 Spree Coins, and when you make your first purchase the casino will match it 200% – providing your purchase is $9.99, great incentive to get going.
There is no app available but you can play on desktop or on a mobile browser. Not a biggie but a point to consider if you like sticking with apps.
One downside is Spree’s slower than average payout times. Gift card redemptions take 24-48 hours, which is reasonable, but bank transfers take as long as 10 days—one of the longest payout times in the space.
On the plus side, the 10 Spree Coin minimum redemption for gifts is one of the lowest in the space.
There’s no progressive jackpot or VIP program, so it’s not a great option for high rollers. Still, support is offered 24/7 via phone and email, which is a big plus.
Overall, Spree Casino has a good collection of games and some great promotions, but faster redemptions and a loyalty program are needed to take it to the next level.
Read our expert Spree casino review here.
Despite some initial hesitations due to mixed reviews, Spree casino quickly won me over with its generous welcome bonus and fast redemption process. Having tested numerous platforms, I was pleased to see my first gift card redemption completed in under 48 hours, a welcome relief compared to the slower payouts common on other sites.<br><br>Spree casino also boasts an extensive selection of games, particularly exclusive slots like Diamond Spree Explosion, which sets it apart from competitors. The games are not only engaging but also offer fair winning opportunities. After multiple cashouts, I can confidently say the platform delivers on its promises.<br><br>While the redemption process was quick for me, I’ve observed that bank transfers can take longer. However, for those utilizing faster methods, Spree remains one of the more responsive and rewarding casinos I’ve encountered. Its consistent performance and player-centric approach solidify its place as a reliable option in the sweepstakes casino market.

2. Stake.us - Best Colorado online casino for payout speed
Stake.us casino overview
Stake.us video review
Summary
Stake.us puts a unique spin on the sweepstakes casino model, doing away with credit card and cash deposits for a crypto-only experience.
You’ll only be able to use cryptocurrency to make deposits and withdrawals, and the transactions you make will be processed extremely quickly and securely.
The platform hosts 600+ games, including titles from popular providers such as Pragmatic Play and Hacksaw Gaming, and Stake Originals.
Stake Originals are exclusive games that you won’t find at any other casino. There are slot games, table games, and a variety of unique games, so you have more than enough to choose from.
There might not be a mobile app to download, but that’s ok, you don’t need one. The mobile site is super speedy, silky smooth, and very well optimized to make game play easy on whatever device you’re using.
New players will be asked to join with a welcome offer consisting of a 550,000 Gold Coin, $55 Stake Cash, and 5% rakeback on any losses suffered.
Compared to other sweepstakes casino welcome offers, this is alright.
The main drawback? Crypto is the only payment method – if you’re not comfortable with digital currency, this isn’t the right fit.
Those who have no issue with using crypto to make transactions, as well as wanting a sleek, user-friendly platform will really like Stake.us.
Read our complete Stake.us casino review.
With years of experience in the online gaming industry, Stake.us immediately impressed me with its fast and secure cryptocurrency-based payouts. Winning on one of their exclusive slots and redeeming my funds in crypto within minutes was a highlight—other platforms rarely match such speed.<br><br>The variety of games on Stake.us is diverse, featuring regular new releases that keep the experience engaging. However, from a professional standpoint, I noticed that the selection of tabletop games could be expanded, particularly for enthusiasts of more niche variants like 3 card poker.<br><br>Despite the focus on cryptocurrency, which could be a challenge for some, I found the transactions both secure and straightforward. Stake.us also excels in its loyalty program, with a VIP structure that genuinely rewards long-term play, offering benefits that far surpass those seen on most other platforms.

4. NoLimitCoins - Best for daily Colorado casino bonuses
NoLimitCoins casino overview
NoLimitCoins video review
Summary
NoLimitCoins is an excellent choice for sweepstakes casino players, particularly those chasing a plentiful welcome bonus.
It offers 1.65 million Gold Coins and 7,000 Free Super Coins to new players, one of the largest no-deposit bonuses there is.
The platform is easy to use, uncluttered, and runs smoothly on desktop and mobile browsers (so no apps to download).
Despite the limited selection, with just 60+ slots and fishing games, in terms of gameplay, the polish of the gameplay and the fact that they largely run without issue makes up for that shortcoming.
Not to mention that this is made up for with daily tournaments and features such as the Lucky Wheel which lets users win as much as 500,000 Super Coins!
No tables games though, the library only contains slots and fish games. A major positive—the support team is available 24/7.
There’s live chat, email, and even phone support, which is extremely rare for a sweepstakes casino.
Redemptions are quick and simple—cash payouts are processed within 48 hours, and gift card redemptions are processed within 24 hours.
Payment options are Visa, Mastercard, and online banking.
If you’re looking for big bonuses, easy-to-navigate site features, and reliable customer service, you can’t go wrong with NoLimitCoins.
Read our complete NoLimitCoins casino review.
As someone who evaluates online casinos, I was particularly impressed with NoLimitCoins' redemption process. During my first withdrawal, I was pleasantly surprised to find the funds in my account by the next morning—arguably the fastest payout I've encountered across various platforms.<br><br>What makes NoLimitCoins stand out is its captivating game options, though the selection is more limited compared to larger competitors. Despite this, the games are visually striking and engaging, providing a high-quality experience. Additionally, the promotions, such as the daily spins on the Lucky Wheel, consistently offer meaningful rewards, enhancing the overall appeal.<br><br>One drawback is the absence of a dedicated mobile app, a feature that many seasoned players, like myself, prefer for convenience. Nevertheless, the mobile browser version is highly optimized and provides smooth, seamless gameplay, ensuring that my favorite titles are easily accessible even on the go.

Funrize video review
Summary
Funrize Casino caters to players who prefer a classic experience over extensive and complex platforms.
What that means is that it offers an accommodating collection of more than 400 games, an array dominated by slot machines. Beyond that, there are daily tournaments and races to keep things spicy.

Best Colorado casino apps
Here's a list of the best Colorado online casino apps with their App store rating for iOS and Android.
Colorado online gambling laws
Online gambling in Colorado is somewhat limited by current state laws.
While real-money online casinos are not yet legalized, the state allows for online sports betting and social or sweepstakes casinos.
These social casinos operate legally by offering virtual currencies like Gold Coins, which can be used for play, and Sweeps Coins, which can be redeemed for cash prizes.
Colorado legalized online sports betting in 2019 with the passing of Proposition DD, which became active in May 2020.
Currently, more than 40 licensed sportsbooks operate within the state.
Although real-money online casinos are prohibited, players can still enjoy online slots and table games at sweepstakes casinos, which operate legally under existing sweepstakes laws.
Colorado’s gambling history dates back to the early 1990s.
In 1990, voters passed the Legalization of Limited Gambling Initiative, which allowed limited-stakes casino gambling in the historic mining towns of Black Hawk, Central City, and Cripple Creek.
The first casinos opened in 1991, initially with a $5 bet cap and restricted hours.
This changed with Colorado Amendment 50 in 2008, which raised the maximum bet limit to $100 and allowed 24/7 operation.
The state has since expanded its gambling options, including tribal casinos, horse racing, and a state lottery.
In 2019, the approval of Proposition DD marked a significant step forward, legalizing sports betting and opening up new opportunities for the online gambling industry.
Responsible online gambling Colorado
Before we end this article, we need to caution you to always bet and play responsibly on the top Colorado casinos online.
To ensure you’re being cautious, these casinos implement various responsible gambling practices that will help you keep your betting habits in check and prevent unhealthy behaviors.
Limits: Online casinos allow you to set betting limits, i.e. limit how much you can bet in a day, a week, or a month.
Cashouts: You can withdraw your winnings quite easily from any online casino. This prevents you from spending all of your winnings. There’s also the option for early cashout, so you can still get paid if the bet is starting to go sideways.
Help & resources: Casinos provide access to resources for problem gamblers and point them to organizations that can help with gambling addiction.
