Underdog Promo Code TOPACTION: Get $100 Bonus for Ravens vs. Dolphins Thursday Night Football
With the Baltimore Ravens and the Miami Dolphins squaring off on Thursday Night Football tonight, sign up with the Underdog promo code TOPACTION to take advantage of a valuable welcome bonus. Let's discuss how this sign-up offer works and how to play your first entry at Underdog Fantasy.
Remember, with this offer, you have a 50% chance at receiving $100 in bonus and a 50% chance at receiving $100 in entries. If you get the entry format for your bonus, it is distributed in 10 equal increments of $10 apiece.
There are two different entry formats available at Underdog Fantasy: Standard and Flex. A Standard entry requires all of your picks to win to receive a payout, while a Flex entry requires you to win all picks or lose just one. The key difference is that a Flex entry provides a much smaller payout for going perfect, so a Standard entry rewards you much more for the risk you take.
Here is an example of an entry I created for Thursday Night Football:
- Lamar Jackson Higher Than 0.5 Rush + Rec TDs
- De'Von Achane Higher Than 0.5 Rush + Rec TDs
- Jaylen Waddle Higher Than 62.5 Receiving Yards
Suppose I place this entry as my $5 initial entry with the Underdog promo code TOPACTION, which has a 5.8x payout multiplier. Here is what I receive based on the outcome of it:
- If all of my picks win, I receive a $29 total payout ($24 profit + $5 entry back) and $100 in bonus entries.
- If one or more of my picks lose, I receive $100 in bonus entries.
