Underdog Fantasy Promo Code TOPACTION: Place MLB Entries Now
Now, let's discuss how entries work when you sign up with the Underdog Fantasy promo code TOPACTION. There are two different entry formats to choose from: Standard and Flex. A Standard entry requires you to win each of your picks to receive a payout, while a Flex provides a smaller payout for going perfect and approximately a 1x payout if you lose just one pick.
Here is an example of an entry I created for MLB today:
- Shohei Ohtani HIGHER than 0.5 Home Runs
- Elly De La Cruz HIGHER than 0.5 Stolen Bases
- Juan Soto HIGHER than 1.5 Hits + Runs + RBI
Say I place this entry as a Standard for $10, which has a 7.5x payout multiplier. If all picks win, I receive a $75 total payout that includes $65 in profit and my $10 entry back. Remember to use the Underdog promo code TOPACTION to secure your offer.
