How to Use Underdog Fantasy Promo Code TOPACTION
Once you’ve signed up and deposited, head to the Underdog Fantasy pick’em section to explore a wide range of NBA player projections. Available NBA categories include points, rebounds, assists, and combined stats like points + rebounds + assists. Your goal is to choose “Higher” or “Lower” for each player projection in your lineup.
Underdog Fantasy allows users to include up to six picks in a single entry, with a maximum payout of 35x. If your lineup includes at least three picks, you must choose between Standard and Flex play:
- Standard Entry: If all your picks are correct, win up to 6x your entry amount.
- Flex Entry: Offers a lower payout but provides a safety net—win 3x if all picks hit, and still earn a 1x payout if one pick falls short.
To showcase how this works, here’s an example of a three-pick lineup built using bonus funds from the Underdog Fantasy promo code TOPACTION for Sunday’s NBA slate:
- Karl-Anthony Towns (Knicks) – Higher than 23.5 Points
- Jayson Tatum (Celtics) – Lower than 26.5 points
- Jalen Brunson (Knicks) – Higher than 2.5 1Q Assists
If you select a Standard entry, you win 6x your wager if all three picks hit. Choosing a Flex entry would provide a 3x payout if all three selections win and still return a 1x payout if one pick falls short.
With NBA stars taking the court across Sunday’s loaded schedule, this is the perfect time to capitalize on Underdog Fantasy’s deposit match bonus. Sign up today with Underdog Fantasy promo code TOPACTION and start making NBA picks with bonus funds.
