Best Colorado Sportsbook Promotions and Bonuses

Loyalty Programs at Colorado Sportsbooks

We like that programs like BetMGM's MGM Rewards or Caesar's Rewards give points and tier placement for every dollar you wager.

There is no cost to join, and you'll probably enroll automatically when you register. These points and statuses can often lead to benefits like free meals, free hotel stays, and exclusive event invitations. This is a nice benefit to consider when choosing between different Colorado sportsbooks.

Most Colorado sportsbooks with a brand connection to a larger casino chain let you participate in the company-wide loyalty program, but BetMGM and Caesar's are two of the best.

Online Sports Betting in Colorado

There are a few things you'll need to know before you start sports betting in Colorado:

To place a wager, you must be 21 years old and be located in the state of Colorado at the time you place your bet. This will be verified by your phone's geolocation tech or a downloadable desktop plugin.

Colorado bettors can bet on all the major league sports (NFL, NBA, WNBA, MLB, NHL), including college football and college basketball. Other sports are available, too, such as European basketball leagues, cricket, and rugby.

If you're in Texas, Utah, New Mexico, Oregon, Oklahoma, or another nearby state and want to bet on sports in Colorado, be sure to use all your accurate information. Refrain from being tempted to use a friend's address or your old address.

You're good if you are in state lines when you place your bet. You must be physically located within the state when you place your bet. You can live out of Colorado.

How to Place an Online Bet in Colorado

Step 3: Deposit Money Online (Not in Person)

Colorado makes it easy by allowing online sports bettors to sign up and register online. In other states, you have to sign up in person before you can bet online.

You can make a deposit at Caesar's with the following:

And more.

You will need to deposit money that then operates as your "bankroll," aka available funds to bet with. Most legal sportsbooks require this deposit before allowing you to place a bet.

Online sportsbooks in Colorado also make cashing out easy. Bet365 will put money right into your bank account whenever you're ready to withdraw it. We've seen withdrawals come through in fewer than 24 hours, though it may take a bit longer in some instances.
