Underdog Promo Code TOPACTION: Get $75 in Bonus Entries for Rams vs. Falcons Monday Night Football
Register with the Underdog promo code TOPACTION to claim $75 in bonus entries for tonight's Monday Night Football matchup between the Los Angeles Rams and the Atlanta Falcons. Simply play $5+ at Underdog Fantasy to get $75 in bonus entries.
There are two different entry formats available to choose between 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 when you win all of your picks, while a Standard entry rewards you much more for the risk you take.
Here is an example of an entry I created for Rams vs. Falcons MNF:
- Puka Nacua Lower Than 108.5 Receiving Yards
- Bijan Robinson Lower Than 74.5 Rushing Yards
- Colby Parkinson Higher Than 0.5 Rush + Rec TDs
Suppose I place this entry as my $5 initial entry with the Underdog promo code TOPACTION, which has a 6.75x payout multiplier. Here is what I receive based on the outcome of it:
- If all of my picks win, I receive a $33.75 total payout ($28.75 profit + $5 entry back) and $75 in bonus entries.
- If one or more of my picks lose, I receive $75 in bonus entries.
