Who is this article suitable for? For those who love sports betting in CO

Sports betting has blossomed into a massive market in the Centennial State as people continue to bet in droves. This includes experienced old heads and new people looking to dip their toes into the betting pool for the first time. The common denominator among them is that they love sports and now, they all love sports betting. And that is precisely who this guide is meant for.

New betting fans in Colorado can take notes from our detailed guide as we show you how to make sure you have a safe gambling experience, how you can find the best betting sites, and who our favorite sportsbook for online betting CO is right now. There is plenty for you to learn to make sure that your first venture into online sports betting in CO is a pleasant one.

For our more experienced readers, there is no betting fan alive that can stay abreast of all the latest sportsbooks that pop up or all the best sportsbook bonuses that are being offered. That is what we do for you. Our guide shows you how you can stay on top of these new sites, how to know which of them have gotten off to the hottest start, and which of them are offering the best new customer deals. So, check out the rest of our guide to see what else you can learn from us.

The history of sports betting in Colorado essentially started in 1948 when votes from Colorado approved the Colorado Gambling on Horse and Animal Races amendment. This allowed for pari-mutuel wagering on horses and greyhounds. This was also where the Colorado Racing Commission was subsequently started. The only other change to the gambling scene for the next few years was the introduction of charitable bingo and casinos sometime in the late 1950s.

As far as sports betting went, greyhound racing would be outlawed in 2014, although a greyhound race had not been run in the state since around 2008. The next major point of order with regard to sports betting in the state was always going to be online sports betting. Proposition DD just squealed through which allowed for the 33 casinos in Colorado to apply for a license to offer online and real sports betting.

Since then, there has been a significant influx of sports betting sites in Colorado that include the biggest names in the industry. Today, Colorado is one of the best places to conduct your sports betting online as there is a multitude of top-quality betting options to choose from.

Editor’s recommendation – don’t be shy to sign up for Unibet

We are all for our users making their own choices., It should fall to you to decide what CO online sportsbooks you want to sign up to. However, if you are struggling or if you find yourself struggling to find a suitable CO sportsbook further down the line, then we would highly recommend going with our editor’s recommendation.

The recommendation we have come up with for our Colorado sports betting fans is Unibet. Unibet is a global brand that stretches across most of Europe and North America. They have built themselves up to be one of the best premier sports betting platforms in the world and now in Colorado. It’s not difficult to see how they have managed to do this with their exceptional sportsbook, lucrative bonus offers, and exciting rewards program. The sportsbook alone would be enough to excite most players as they have just about every sport available to men on their site.

To boost your experience on their site, they have a fantastic welcome offer that is complemented by several promotions on the site. These promotions are changed every other month to keep things fresh and exciting for bettors on the site. And if that wasn’t enough, you can sink your teeth into their stellar loyalty program where even more rewards can be gained through simply betting on the site more often.

Few sportsbooks in Colorado can match the quality of Unibet. That is not an offense towards these other sportsbooks. Unibet is just that good. We consider them to be one of the best Illinois sports betting sites as well.

Five tips to make sure you are gambling safely in CO

The US and Colorado in particular run a tight ship when it comes to regulated online sportsbooks, but that doesn’t mean you can’t check these sites out for yourself to make sure they are safe enough for you to use. There will always be sites that are trying to cut corners and operate in a legal gray area, so it’s best to know what to look out for to ensure that you have a safe online sports betting experience in Colorado. Here are a couple of important things to keep an eye on.

Regulated and licensed

First things first, you need to make sure that sites for sports betting in Colorado are fully licensed and regulated. You can do this by checking out the homepage on these sites and scrolling to the bottom. You will typically find the license number and who has issued the license to the operator there. You want to look for the stamp of approval from the Colorado Division of Gaming. If the CDG has given the sites for sports betting in CO you have checked out the green light, you can rest assured that they have gone through all the necessary steps to operate legally within the state.

Strong platform security

Something that is arguably as important as the licensing and regulation is how well these Colorado online sports betting sites protect their users. Look out for if they are using the latest SSL encryption software to layer your data. This software helps make sensitive information like your login and banking details far more difficult to read for any hackers. In addition to this SSL encryption software, look for any 2-factor authentication features, which will usually be in place for your logins and deposit/withdrawal transactions. They add another step to the process, which makes it more difficult for anyone to enter your account without your knowledge or steal funds from your betting account.

Responsible gambling practices

If the CO online sports betting sites you are interested in are invested in responsible gambling practices, that is already a perfect sign. For example, if they allow users to set their own account limits for their maximum deposit amount or weekly betting limits, that shows they are trying to help players curb addiction or poor gambling habits. If these CO online sportsbooks are making links to helpful organizations available, that is another sign that they care about their players.

Transparent privacy policy

This is a factor that not many users on these Colorado online sportsbooks would think of. Still, a transparent privacy policy is more important than you think. The honest Colorado sportsbooks will make their privacy policy readily accessible and easy to view. Those trying to hide what they do with your data will have their privacy policy on their site but it will be far more difficult to locate. You can trust the Colorado sportsbooks that are open and honest with their privacy policies much more than those that aren’t.

Customer service

A professional and notably caring customer support team goes a long way to making users feel like the site they are using is safe. That is why we suggest that you take the time to test a few of these services out for yourself before you actually commit to using the site. If they respond in a timely fashion and treat your queries with professionalism and respect, that’s a good sign that you can establish trust with the sportsbook. This should be kept in mind even when you are checking out the best Virginia sports betting sites as well. 

What we look out for on CO operators’ sites 

Our team of experts conducts a plethora of reviews, and in these reviews, we stick to specific criteria that we think are most important. These criteria include key factors that you can find below:

  1. Bonuses and promos: We never want our readers to miss out on an opportunity to claim a promo or a bonus. That is why when we conduct reviews of Colorado sports betting sites, we make sure that we give you the breakdown of what offers they have available, how much you can claim from these offers, what you’ll need to do to withdraw your winnings successfully, and more.
  2. Website functionality: Next up, we look at how easy it is to use these sites. Could someone new to sports betting successfully navigate the platform? Is it fitting for someone who has been into sports betting for a long time? We take a look at the platform from every angle to make sure that it is, at the very least, easy to use.
  3. License and security: We will never leave out our section on licensing and security. We will never recommend a site to you that isn’t fully licensed and regulated and does not have sufficient protection in place to protect the users’ interests.
  4. Deposit options: Sites for sports betting in CO need to make a decent selection of deposit methods available to their users. Everyone has their payment preferences, so we give you a clear rundown of what options are available with these sites for sports betting in Colorado.
  5. Customer service: If customer service for these sites for online betting in Colorado is poor, that can sour your overall betting experience. As such, our reviews always test these services out for you. Once we have done that, we will give you some insight into our experience and whether or not we were satisfied with what we found.
  6. Rewards programs: The next thing we analyze is whether or not the best sports betting sites CO has to offer have rewards programs available. These loyalty programs are a great way to keep users invested in the site, which is why we let you know how they work, what you can potentially get out of them, and how realistic they make the earning of points.
  7. Range of sports: The range of sports with these CO online sportsbooks is another critical factor. Most users are there because they want to bet on their favorite teams. As such, we review the range of sports, whether they include international leagues and events, and what some of the more obscure sports they offer. We are equally as analytical when we look at the best site for sports betting in Michigan.
  8. Betting markets: just as important as the range of sports is the range of betting markets. These markets are crucial to making your sports betting experience more enjoyable. Trust us, if you stick to the same old betting markets every time, you bet your betting experience will get very dull very quickly. As such, we check to see that these CO online sportsbooks are providing enough diverse markets for users to choose from.
  9. Live betting and streaming: The best sports betting sites Colorado has to offer will not only make a live betting feature available, but they will also have a live streaming service. Not all sportsbooks have a live streaming service, but they improve your experience on the site. As such, we analyze the quality of the live betting feature and check to see if they are also offering a live streaming service.
