How We Selected The Best Colorado Sportsbook Promos

Our team of Colorado sports betting experts has been hard at work reviewing the various sportsbooks in the state and holding them to a strict list of criteria to bring only the best in the business to this list for new customers. The criteria these are up against can be found below, and we explain why these are the most important features to compare against. 

Intro the section explaining that our expert team will judge sportsbooks by a strict list of criteria before explaining with 100+ words why each of the following factors is important when determining which Colorado sportsbook promos are the best.

Security and Licensing

Every single one of the best Colorado sportsbook promos included in this article is 100% legal and licensed to be playing at and operating in Colorado. Possibly one of the most important on the list of criteria, new customers can be assured that we would only bring you sportsbooks that are legitimate and regulated. All of these sportsbooks are safe to play at with secure transactions and official features, and players can put their minds at rest that scammers are pocketing none of their personal information or money.

Welcome Bonus

Once confirming the legality of the site, our experts move on to reviewing the welcome bonuses being run across the sites. We will only recommend sportsbook promos that are worth players' time and that provide value. These must also have terms and conditions that are not complicated to comprehend and meet - no one needs that. A site's welcome offer is what will attract new players or make them find somewhere else to go, so we must include only more rewarding and best in the business.

Site Reputation

Next, we look at the reputation of the Colorado sports betting sites. An important contributor to this category is the customer reviews. Our experts, alongside their own experiences, head to player's reviews to get a feel for the consensus of the user experience. All of the sites included here have received significantly more positive reviews than negative ones from new and existing players, assuring us, too, that our good experiences were not just a one-off.

Payment Options

Another hugely important factor when it comes to choosing the best Colorado Sportsbook promos is that there is a good range of payment methods available for players. These need to be safe, secure and reputable providers that players know they can trust. Deposits and withdrawals should also be easy to complete with minimal customer intervention. Meet all of these and feature them on our best sportsbook promos list.

Types Of Colorado Sportsbook Promos

This next section will look at the different types of sportsbook promos in Colorado offered across the platforms included in this article. 

First Bet Insurance/Second Chance Bets

First bet Insurance and Second chance bets, in simple terms, mean that the sportsbook will offer customers their stake back, albeit in the form of bonus bets. These are matched 100%, similar to the BetMGM offer in this article: receive up to $1,000 back in bonus bets if your bet loses, matched to what you wagered originally.

Deposit Match Bonus

The deposit match bonus does as it says on the tin. The sportsbook will match the customer's initial deposit and award it back to them through bonus bets up to a certain amount. These do typically have attached to them minimum and maximum deposit requirements and limits.

No Deposit Bonus

This type of bonus is rather rare to find. It's when one of the sportsbooks rewards players with a bonus just for signing up. These have no minimum deposit or qualifying bet that needs to be done before receiving the bonus. The bonus will be deposited into the player's account automatically at sign-up. 

Colorado Sports Betting Promos Terms and Conditions

There are, as always, several common terms and conditions that will need to be met and followed to ensure that any of these Colorado sportsbook offers are successfully claimed.

Promo Code

Most sites will require a specific promo code to be entered during the sign-up process to claim the offered bonus. This will be included in the promotion and in the terms and conditions. A number of the Colorado sportsbook promos listed above require new users to enter a promo code to be eligible for the deal on offer.

Wagering Requirements

Some bonuses will require a player's winnings to be turned over a certain number of times before making a withdrawal is possible on the platform. To claim the welcome offer, players would need to complete their first bet with the platform to then benefit from the offer applied to the second bet that is placed. An example of this is the BetRivers 2nd chance bet above.

Must Be In Colorado

Of course, players wishing to take advantage of the best Colorado sportsbook promos will need to be in Colorado for them to be claimed and valid. Any players that are not located in Colorado, unfortunately, will not be eligible for these promotions. 

New Users Only

These welcome offers are exclusive to new customers only at the various Colorado sportsbooks. A new account will be required to be created with details not previously recorded on the site to go ahead and claim these bonuses. Unfortunately, if you are not a new user of the platform, you will not be able to claim these.

One Bonus Per User

As would be expected, all of these Colorado sportsbook promotions are limited to one per user at sign-up. If this has already been claimed on an existing account by another user, unfortunately, the player would be unable to claim this again.

Bonus Expiry Date

Every Colorado sportsbook promo code will have a set expiration date. Up until this date, the offer can be claimed on the account, but once this date has passed, unfortunately this promotion will no longer be running, and the promo code will be invalid. This is typically within seven days of sign-up. However, some can be longer. We recommend checking each promo's terms and conditions for this information.

Minimum Deposit

There will always be a minimum deposit amount required for each of the promos included in this article that must be met to be eligible for the promo. Whether this is a minimum deposit amount or placing your first bet and getting benefits to use on your second, it is unlikely that the welcome offer will be completely deposit-free.
