How to Activate the Underdog Promo Code

Getting started with this offer is a simple process. Follow these steps to claim your $100 in bonus entries ahead of the Bills vs Broncos game:

1. Create Your Account: First, you’ll need to sign up for a new Underdog account. During registration, you will be prompted to enter the promo code BROAD. Be prepared to provide standard personal information to verify your identity. Remember, this offer is only for new users who meet the age (18+, 19+, or 21+ depending on the state) and location requirements.
2. Make a Deposit: Once registered, make your first deposit of at least $5 using one of the available secure payment methods.
3. Place Your First Entry: Build your first entry with a stake of at least $5. This initial play will instantly trigger the bonus.
4. Receive Your Bonus: After completing your $5 entry, $75 in bonus funds will be credited to your account as ten separate $10 entries.

When building your entries, you have a couple of options. A Standard entry requires at least two picks and offers the highest potential payout, but every single pick must be correct to win. For example, a standard entry could combine multiple player selections for the Bills vs Broncos matchup.

Alternatively, you can choose a Flex entry, which requires three or more picks. This format provides a safety net, allowing you to still receive a payout even if one of your picks is incorrect. A flex entry could involve taking multiple player selections, giving you a cushion for your playoff predictions.
