Colorado Sports Betting Sites Launching Soon:

888 Sportsbook 

888 Sportsbook isn’t here yet. But when it is, it will offer a $500 risk-free bet. However, that could change for Colorado before launching.


Bet365 is a maybe, too. However, if it comes to Colorado, bettors would be able to claim a $100 first deposit bonus. It’d be the smallest deposit bonus in Colorado at that rate. 

Colorado Sports Betting Promotions

Existing users can take part in sports betting promotions offered at many of the Colorado sports betting sites. Deposit bonuses reward bettors for how much they deposit and wager. Risk-free bets refund losing bets with site credits. 

However, bettors will find ongoing bonuses that offer small wagers on popular games. There are lots to see, so bettors should keep an eye out for new promotions. 

Deposit Bonuses

Deposit bonuses appear the most enticing. They reward bettors for how much they deposit upfront. Sportsbooks seem to know that bettors who deposit money will use it, so it makes sense for them to incentivize large deposits. Deposit bonuses are awarded at a rate expressed as a percentage. A 20% deposit bonus, like DraftKings’, awards 20% of a bettor’s deposit in site credits. So, a $100 deposit would earn $20 in site credits. 

However, deposit bonuses often have playthrough requirements too. Bettors need to actually use the money they deposit before unlocking their bonuses. theScore Bet awards 5% of a bettor’s wagers up to the amount they deposited upfront. That way, sportsbooks ensure bettors are actually wagering. 

Risk-Free Bets

Ironically, risk-free bets require bettors to risk their own money upfront. Risk-free bets reimburse bettors for how much they lose on their first bet. The advertised amount is often the maximum bet that bettors can be reimbursed for in full. So, a $500 risk-free bet often means that bettors can lose $500 on their first bet, then get that money back in site credits. However, bettors can’t withdraw the site credits. Bettors can only get their winnings in the bank. Since these bonuses are often only good for the first bet, new bettors often miss the chance to use them. Don’t be one of them. Plan the first bet carefully. 

No-Deposit Bonuses 

These are small, unremarkable bonuses that bettors receive upon sign up. However, these are in the form of site credits too. They’re not free money for bettors to withdraw and use as they please. Bettors must use those credits to wager at their sportsbooks or forfeit them. They’re usually not larger than $50, so don’t get too excited about them. Barstool Sportsbook offers a $10 no-deposit bonus for signing up, knowing they’ll win that money back over time. However, they can help new and nervous bettors try betting for the first time. Sportsbooks likely use these to lure the most cautious of new bettors in, hoping they’ll wager more after using these first site credits. 

Ongoing Event Bonuses

These are other small bonuses that are tied to specific events. BetMGM offers a deal where bettors wager $50 on college basketball and get a $25 free bet for college football. Little bundles like these help spread bets over all the events sportsbooks need money on. 

How To Claim Online Sportsbook Bonuses In State

Claiming bonuses tends to be straightforward. First, bettors have to find the online sportsbook app they want to wager at. That’s as easy as googling the website or searching the app store. Keep in mind that some brands have state-specific apps. If the Colorado app is available, choose that one. And don’t mistake a daily fantasy sports app for a sportsbook. They’re not the same. 

After that, bettors must register for accounts. Creating accounts is similar to any other website. However, sportsbooks require part or all of a bettor’s social security number. That may seem strange to new bettors. However, it’s part of an identity verification step that all licensed Colorado sportsbooks must adhere to. No one wants to award money to money launderers, after all. 

Once bettors are registered, they just have to fulfill the first terms of the welcome bonus. That could mean different things for different bonuses and sportsbooks. For example, DraftKings offers a $1,000 deposit bonus. However, they have different ways to unlock the full promo. DraftKings requires a large deposit upfront followed by a 25:1 playthrough requirement. But theScore Bet only requires a 20:1 playthrough. That means earning the full deposit bonus requires $5,000 less at theScore Bet than at DraftKings. 

But risk-free bets come with their own terms, too. Their terms often hinge on the first wager. That means planning to bet big later is a poor strategy for fulfilling those terms. Read up on bonus terms before wagering if you want to take advantage of them. 

Once the terms are fulfilled, bettors will find the bonus in their accounts. That could be site credits for additional betting or risk-free bets worth redeeming. Bettors should check their accounts and bet slips if they’re looking for the rewards they reaped from their sportsbook bonus. 

Colorado Sports Betting Bonus FAQs

How old do bettors need to be to place online sports bets in Colorado?

21. While daily fantasy sports players only need to be 18, sports bettors must be 21. This staves off a potentially thorny legislative issue. The idea of high school seniors gambling online is unsettling, even to gambling supporters. Raising the sports betting age got around that and likely helped keep mobile sports betting out of high schools.

Can bettors claim bonuses at more than one Colorado sportsbook?

Yes. Because bettors create separate accounts at each sportsbook, they can claim each sportsbook’s bonus. However, they can only claim bonuses once. Each sportsbook account is tied to a social security number. It’s hard to fake two accounts. Even if bettors could borrow a social security number, sportsbooks would suspend that account if they suspected that it was the same person. Sportsbooks have massive sets of data to use to identify duplicate accounts. Fooling them isn’t as easy as bettors may think. 

What are the playthrough requirements for legal online Colorado sportsbooks?

Each playthrough requirement can differ from sportsbook to sportsbook. However, most of them are associated with deposit bonuses. After fulfilling the deposit requirement for a deposit bonus, bettors often have to wager their money to unlock site credits. They can take the form of fixed site credits per dollar wagered or a percentage of wagered dollars. Bettors must understand each bonus to learn how they wish to fulfill their playthrough requirements.

What’s bonus abuse and how do I avoid it?

Bonus abuse is using multiple accounts to benefit from bonuses multiple times. Sportsbooks anticipate a certain return-on-investment from their bonuses. They expect to spend a little money to retain bettors over their full customer lifetimes. But those calculations assume one bonus per sportsbook. Any more than that is theft.

As long as bettors aren’t creating multiple accounts to profit from different bonus terms, then they’re fine. They can create single accounts at multiple sportsbooks, but creating multiple accounts at any sportsbook will get them in trouble.

What’s the bonus at DraftKings Sportsbook in Colorado?

DraftKings Sportsbook offers a $1,000 deposit bonus at a 20% match rate. If bettors deposit $100, they can earn up to $20 in site credits. However, bettors also have to use the money to bet. DraftKings requires its bettors to play $25 to earn each $1 of site credit. In the $20 example, a bettor would need to wager $500 for the bonus credits. For the full $1,000, bettors would need to play $25,000. Bettors are rewarded based on how much they deposit and play. As long as bettors are wagering at the pace they’ll normally wager, they’re getting a fair value of the bonus.

What’s FanDuel Sportsbook Colorado's bonus?

FanDuel offers a $1,000 risk-free bet to its new bettors. If a bettor’s first wager loses, then they’ll get site credits back equal to their losing bet, up to $1,000. Betting big on the first wager may be a good value for bettors with cash to spare. However, site credits are not the same as winnings. Bettors can withdraw winnings from their accounts. They cannot withdraw site credits. Bettors can only use site credits for betting on FanDuel.

Is there a wager requirement for Colorado sports betting apps?

Sometimes. Some sportsbooks require bettors to use their bonuses on bets with certain odds. Colorado sportsbooks usually set the minimum odds around -200. That way, sportsbooks don’t lose too much money giving away bonus credits and paying additional winnings. Each sportsbook bonus has its own terms, but this is the most common one. Bettors have to watch for these on risk-free bets more than anywhere else. Otherwise, bonus terms should be largely clear.
