Whether you’re using your desktop computer, smartphone, or tablet, getting set up with Colorado betting sites is straightforward. The order in which you create an account may differ between operators - some might ask you to create a username and password first, others will focus on personal information - but, either way, the same process applies.

Here’s all you need to do to get started.

Pick A Betting Site

Before betting on anything, you must decide which betting site is right for you. Especially in a state like Colorado with so many strong candidates!

Create Your Account

Next up, enter the necessary information for your betting site to confirm your account and identity. Most of the registration steps are self-explanatory, but it helps to have ID and personal info readily available.

Claim Your Bonus (if necessary)

If you chose a betting site that doesn't automatically apply your welcome bonus, this is the step where you ensure that you've claimed the reward or entered an applicable promo code with your new account. Taking advantage of a welcome offer is the best way to get a strong start with your account, so pay close attention to the details.

Make Your First Deposit

Putting money into your account will allow you to bet and may be the next step in triggering a welcome bonus, depending on the betting site. Choose your preferred method, whether it's straight from the bank or through popular e-wallets like Venmo, PayPal, and Apple Pay.

Place Your First Bet

Now that your account has funds, you can place wagers! Find your first bet, choose your bet amount, and confirm your wager. If your first bet is part of a welcome bonus, make sure it meets the terms and a corresponding token is applied if necessary. Once your bet is in, you've placed your first sports wager!

Withdraw Your Winnings

When you're ready to take money out, it's just like putting money in. Submit your withdrawal request through your preferred method and wait for it to process. Once the transaction is complete, you will have your profits in hand!
