The Betting America difference

Wherever you live, our mission is to help you find the best online sportsbooks in your state. Because the world of online sports betting is growing so fast, new sites – some of them legit, some of them not – pop up all the time.

These are the top online sports betting providers in CO:   
One of the biggest names in the world of gambling entertainment. Rebranded from William Hill in 2021 and is a hugely popular option for US bettors. Easy to use software and favorable odds makes Caesars Sportsbook a fan favorite, and undoubtedly one of CO’s best online sportsbooks. Excellent bonuses are available for new users!  
One of the newest and most exciting entrants to the sports betting scene. Following on from its success in Australia, PointsBet brings its own unique “PointsBetting” product to the US market. Traditional fixed odds betting also available, good software and plenty of weekly promotions. A must try among Colorado’s best betting sites.   
The MGM brand needs no further introduction. Since launch, BetMGM sportsbook has lived up to the reputation of its famous name. A highly popular choice across the legalized states, it has an intuitive interface and competitive odds. Already challenging the early dominance of DraftKings and FanDuel in some regions, this top online sportsbook offers new users a generous bonus to join the action.  
DraftKings Sportsbook has taken its Fantasy Sports success to the fully legal sports betting market. The DK platform offers a full range of sports and markets to bet on and the software is easy to use. DraftKings is at the forefront of America’s regulated betting industry and consistently launches on Day One when a new legal state goes live.  
BetRivers Sportsbook has seen a rapid growth in popularity. A sister brand to SugarHouse sportsbook and casino, it offers a highly trusted platform and industry leading customer support. Originally known for its casino offerings, BetRivers has taken to sports betting like a duck to water. There is a generous bonus available to users who have not previously registered a BetRivers online account, making this one of the best online sports betting platforms for new Coloradan players.   
Unibet is a leading European sportsbook with a proven track record over the past couple of decades. In recent times, it has brought a cutting edge sports betting platform to legal states such as New Jersey, Pennsylvania, Indiana and Virginia. Keep an eye out for the Unibet app landing in your area as new users are treated to a selection of free bets to get them started.


The best promos are given to new users of a sportsbook. The exact promo offer will vary by sportsbook but here is a rundown of the most common types.  
Free Bets/No Deposit Bonus:
No-deposit bonuses are simple: you sign up to an account and on registration you are given a free bet. You do not need to deposit but it is usually for new accounts only.  
Risk-Free Bets:
With a risk-free bet you have the chance to place a wager where if you lose you get credited back the amount you lost in the form of a free bet. They are essentially a bet where you can’t lose, e.g. you place a risk-free $20 bet on the Patriots to win but they lose, you get a $20 free bet.  
Deposit/Match Bonus:
Matched Bonuses are usually on your first deposit only. It requires you to deposit and the sportsbook will match your deposit amount or a % of your deposit. There are typically playthrough requirements to release these bonuses. In some cases there might only be a 1x playthrough requirement but others can be up to 50x. The latter makes the offer not as attractive because you will have to make a lot of bets before your bonus money is available to withdraw.  
Reload Bonus:
Reload bonus are offered from time to time. You re-deposit money into an already established account and get some form of site credit. It is usually in the form of a matched bonus.  
Refer A Friend:
This is a bonus you get for referring a friend to register a new account with one of the sportsbooks or casinos. When they complete their account registration, make a deposit or place their first bet you get credit to your account. The exact form of credit depends on your specific provider’s offer.  
Will be a refund/site credit on net losses or a % of net losses. These are usually subject to certain playthrough requirements and a specified timeframe.  
Odds Boosts:
The player receives better odds for a particular sporting event. Example: a boxer who is +120 to win a fight might be boosted to +140 on a particular site. This gives extra value to the bettor.  
Loyalty/Bonus Programs:
Bonuses and VIP Awards are given when you play through a certain amount of money and are usually released in small increments. Some sportsbooks may offer these VIP rewards in the form of tickets to sporting events for high volume/ high wagering bettors. Not all sportsbooks offer VIP Rewards.


The best online sportsbooks in Colorado offer a variety of incentives to new users. Some will give you a free bet just for signing up a new account. The more common offer is to give a bonus to new players when they make their first deposit. The bonus is usually proportional to the size of the deposit and can be in the form of a free bet or a risk-free bet.
