CO BEST SPORTSBOOK PROMOS 

CO sportsbook promos went live alongside the official launch of online sports betting in the state on May 1, 2020. This launch came after a referendum voted in to allow for legal sports betting just before the turn of the decade in late 2019.

Below, I’ll navigate the current Colorado sportsbook promos and also look at what each of the top sites in the state offers in terms of features and whether there are any notable betting markets.

BetMGM Sportsbook Promos and Bonuses in Colorado

You can use BetMGM Sportsbook bonus code GRIDBETS in CO to redeem your welcome offer.

Beyond the welcome bonus, you’ll find several Colorado sports betting promotions to redeem.  

These are all short-term offers, but I’ll list and explain some of them so you know what kinds of promotions to expect here. 

• EPL 2 Up Early Payout: You’ll automatically be paid out on EPL straight bets if the team you bet on goes up by two goals.
• Grand Slam Jackpot: Be part of a $50,000 bonus bet payout if you wager on an MLB player to hit a home run, and they not only hit a home run, but it’s a grand slam.
• MLB Baseball Bet Fest Leaderboard: Climb the leaderboard with each MLB wager of $10 and on markets with minimum odds of +100. The higher the odds (+1000 or +10000), the more points you’ll receive.
• Multi-Sport Parlay Boost Token: If the parlay you create has multiple sports, you’ll receive a parlay boost token at 33% off.
• Swing for the Fences Free-to-Play Game: Receive bonus bets for each home run you hit. 

There are a lot of offers to look forward to at BetMGM Sportsbook CO.

I mentioned a parlay boost token, and that’s a great offer here as I consider BetMGM the best online sports betting site for parlays.

Here, you’ll have several pre-built Same Game Parlays for each game. There’s also the Easy Parlay page, which makes building parlays easy. You can sort by sport and market to easily view all possible wagers to parlay.

Banking methods include prepaid cards, e-wallets, bank transfers, debit/credit cards, and even the BetMGM-branded gift card.

bet365 Sportsbook Promos and Bonuses in Colorado

There’s no bet365 Sportsbook bonus code in CO required, but you can use “SGRID" to redeem your offer.

Other long-term promotions are available after you’ve used up the welcome bonus, too.  These include early payouts on sports like baseball, hockey, CFL, and WNBA.  

Here’s how these work:

• Baseball Early Payout: All straight bets are immediately paid out after the team you bet on goes up by five runs.
• Hockey: Immediate payout if your team goes up by three goals.
• CFL: Immediate payout if your team goes up by 20.
• WNBA: Immediate payout if your team goes up by 18. 

There’s also a parlay boost that can go up to 100%. It’s all based on the number of legs in a successful parlay.

Here’s how that shakes out:

• 2 Leg Parlays: 2.5% boost
• 3 Leg Parlays: 5% boost
• 4 Leg Parlays: 7.5% boost
• 5 Leg Parlays: 10% boost
• 6 Leg Parlays: 12.5% boost
• 7 Leg Parlays: 15% boost
• 8 Leg Parlays: 20% boost
• 9 Leg Parlays: 25% boost
• 10 Leg Parlays: 30% boost
• 11 Leg Parlays: 35% boost
• 12 Leg Parlays: 40% boost
• 13 Leg Parlays: 45% boost
• 14 Leg Parlays: 50% boost

• 17 Leg Parlays: 70% boost
• 18 Leg Parlays: 80% boost
• 19 Leg Parlays: 90% boost
• 20 Leg Parlays: 100% boost 

There are other features to enjoy, too, such as Same Game Parlay+, which allows you to add multiple SGPs to one betslip, the golf live tracker to follow your favorite players, and the ability to edit your bet, which allows you to add and swap, or remove picks.

bet365 is available in numerous states, and one feature it has in Colorado that isn’t available everywhere is Daily Lineups. This is bet365’s version of daily fantasy sports, where you can build lineups similar to FanDuel or DraftKings.

Banking methods include debit/credit cards, Apple Pay, online banking, PayPal, PayNearMe, and more.

FanDuel Sportsbook Promos and Bonuses in Colorado

There’s no FanDuel Sportsbook bonus code in CO.

Other promotions at FanDuel Sportsbook CO include 30% Same Game Parlay profit boosts for sports like the WNBA, soccer, and baseball. There’s also a 25% profit boost available for golf.

Players in Colorado can also earn $50 in bonus bets per friend they refer to the site. The bonus bets are given after your friend signs up using your exclusive link and completing the requirements.

There are numerous features to look for at FanDuel Sportsbook CO. Here are some of my favorites:

• Betting 101 Guide: This guide assists new players in understanding the basics of sports betting and provides text and video content for specific sports.
• Parlay Hub: Filter betting options by sport, market, and odds to see what you could add to your parlay bet slip.
• Daily Fantasy Sports: FanDuel’s popularity skyrocketed in the early 2010s thanks to its daily fantasy sports platform, which is still available today.
• Boosts: Find daily odds boosts to hopefully add more cash to your wallet.

Payment methods include debit cards, e-wallets (PayPal, Venmo), Apple Pay, online banking, and the third-party GAMEON Gift Card.

DraftKings Sportsbook Promos and Bonuses in Colorado

There’s no DraftKings Sportsbook bonus code in CO to get redeem your sign up offer.  

After the welcome bonus, DraftKings has many offers available, but they typically have a short shelf life. The most common include profit boosts, stepped up parlays (a term used for a profit boost), refer-a-friend and more. 

There’s a rewards program here, too. When you wager, you’ll earn DK Crowns, which can be redeemed for bonus bets. Every 550 crowns is $1 in bonus bets. 

Here’s how you get the crowns:

• Parlays/Same Game Parlays: A $1 wager earns 1 Crown.
• Straight bets/Futures: A $2 wager earns 1 Crown.  

There are many features at DraftKings, and I’ll start with my favorite, which is actually more of a betting market: player props.

Sure, player props are available at almost every online sports betting site, but none have the number of markets or the depth of players DraftKings has.

Here are some other features:

• Pools: Join for free or with a fee and compete against other players for prize money.
• NFL Survivor Pools: Make selections for NFL games throughout the season. The more you get right, the further you advance. 
• DK Social: This is somewhat like a social media app, but I use it to add friends to a betting group. When you do this, you’ll see what all your friends are betting on and can either join their selection or ask them why they wanted to bet on that. 
• DFS: Like FanDuel, DraftKings became popular with DFS in the early 2010s. The Millionaire Maker tournament was a massive success.  

Payment methods here include Apple Pay, Venmo, PayPal, online banking, debit cards, the DraftKings-branded gift card, and many more.  

Fanatics Sportsbook Promos and Bonuses in Colorado

There’s no Fanatics Sportsbook bonus code in CO for the welcome offer.

Beyond the welcome bonus, there’s only one other promotion and the rewards program.  

The one promotions that’s available is “Last Leg Letdown.” Each week, Fanatics Sportsbook CO will be pick 20 parlays that lost by one leg and award that player with FanCash. 

Speaking of FanCash, that’s the rewards program here.

With FanCash, you’ll receive a percentage of your wager back, up to 10%. FanCash can then be used for bonus bets or as site credit to venture on over to the Fanatics online retailer, where you can purchase jerseys of your favorite players.

Another feature here is the withdrawal tracker. You can keep up with your withdrawal as it moves through processing.

Payment methods here include debit cards, online banking, and more.

Caesars Sportsbook Promos and Bonuses in Colorado

The Caesars Sportsbook bonus code in CO is “SGRID1000”  

Some other promotions here you can expect to find include parlay profit boosts, straight bet profit boosts, and the refer-a-friend program.

Instead of bonus bets, though, the refer-a-friend program gives you Reward Credits, which tie into Caesars Rewards. This is a rewards program where you can Tier and Reward Credits and redeem them for in-person and online perks and benefits.

There are numerous features at Caesars Sportsbook, headlined by the odds boosts. The odds boosts are what I’d say Caesars Sportsbook CO is best known for. Like DraftKings’ player props, there are sportsbooks with odds boosts, but Caesars seemingly never has less than 40 on a daily basis.

Here are some other features I enjoy a lot when playing here:

• Fire Bets: This takes live betting to a whole new level. You can wager on specific events within games, like the result of the next batter in baseball, how the next play in a football game will go, and more. You can select specific games to follow along with.
• NFL Live Streaming: Caesars Sportsbook partnered with Genius Sports to allow for NFL live streaming on select games.

Banking methods here include debit cards, PayNearMe, Apple Pay, Venmo, PayPal, and more.

 

How can you claim the sports betting promos in Colorado?  

Now that I’ve discussed sports betting promos in Colorado above, it’s fair to wonder how exactly you obtain those.

Below, I’ll cover that and other promotions you can find throughout sportsbooks in the state.

Types of promos and bonuses in Colorado?

You’ll find many types of promotions and bonuses at CO sports betting sites. Below are some of the most notable.

• Bonus Bets: This is the currency you’ll receive from CO sports betting sites after engaging in promotions and bonuses. These are used to make wagers, but you won’t get the amount of the bonus bet back with successful bets. For example, if you have a bet with odds of +100 and wager $10 in bonus bets, you’ll get the $10 in winnings back, but not the initial $10 wager. 
• Deposit Bonuses: A deposit bonus provides a percentage match up to a specific amount. A popular example is a 100% match up to $1,000. So, if you deposit $1,000, you’ll get $1,000 in bonus bets. 
• Welcome Bonus: This is the introductory offer to a new sports betting site. These typically feature massive bonus bet opportunities, whether you get your first wager back or an amount after making a wager. 
• No-Deposit Bonus: A no-deposit bonus is something you receive after signing up for an account. These bonuses are pretty low—$10 to $25—but you get it just for creating an account. 
• Rewards Program: These present themselves in many ways. Sites like Caesars and BetMGM have programs for in-person and online benefits, while DraftKings has DK Crowns, which can be used for bonus bets. Fanatics is unique in that it’s like an online retailer, so you can use FanCash to buy jerseys and other memorabilia. 
• Refer-A-Friend: With these offers, you send a unique code or link to a friend. They complete the requirements, and you get bonus bets or reward points. 
• Bet & Get: This offer is exactly how it sounds. You’ll “bet” an amount and “get” something back. Like at DraftKings, you bet the $5 and get $150 in bonus bets. 
• Bet Insurance: With bet insurance, you’ll get an amount back in bonus bets if it loses. This offer takes on many forms, including parlays, where if one leg loses, you get bonus bets back.
• Odds Boosts: With this promo, the sportsbook will enhance the odds of a wager, potentially allowing for more earnings.
• Profit Boost: If you meet the promotion’s requirements, your payout will be improved by a certain percentage.    

Steps to claim a bonus in Colorado?

1. Click our exclusive links to go to the site.
2. Click the appropriate button to register for an account.
3. Provide your name, address, date of birth, and social security number. If a promo code is required, you may need to use it here. 
4. Once you’ve created an account, you must consent to the sportsbook tracking your location; this is required by state law.
5. Once confirmed, make your first deposit. Make sure it aligns with the terms and conditions of the welcome bonus.
6. Receive the bonus after making your first wager and losing or simply making a bet.

In some cases, you may need to show proof of your identity. If this is the case, the sportsbook will have an encrypted link where you’ll upload a picture of your government-issued ID. This is typically required if you’ve recently moved or changed your name.

For other promotions other than the welcome bonus, claiming them is quite simple: You’ll either follow the wager guidelines and get it naturally or opt-in.

Is sports betting legal in Colorado?

Yes, online sports betting in Colorado is legal.

It started after HB 1327 was sent to Governor Polis for a signature. From there, voters in the state voted in favor of it in November of that year by a margin of less than 1%. 

The first Colorado sports betting sites went live in May 2020.
