Underdog Promo Code TOPACTION: Get $100 in Bonus Entries for Jets vs. Patriots Thursday Night Football
Register now with the Underdog promo code TOPACTION to claim $100 in bonus entries for Jets vs. Patriots on Thursday Night Football. Simply play $5+ at Underdog Fantasy to get $100 in bonus entries. Keep in mind that the bonus is distributed in 10 equal increments of $10 apiece. Each bonus entry does not have an expiration date.
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 tonight's Thursday Night Football matchup between the New York Jets and the New England Patriots:
- Drake Maye Higher Than 238.5 Passing Yards
- Breece Hall Higher Than 0.5 Rush + Rec TDs
- DeMario Douglas Higher Than 22.5 Receiving Yards
Suppose I place this entry as my $5 initial entry with the Underdog promo code TOPACTION, which has a 8x payout multiplier. Here is what I receive based on the outcome of it:
- If all of my picks win, I receive a $40 total payout ($35 profit + $5 entry back) and $100 in bonus entries.
- If one or more of my picks lose, I receive $100 in bonus entries.
