Underdog Promo Code TOPACTION: Grab $50 Bonus with $5+ NFL, NCAAF Entry Today
When you sign up today with the Underdog promo code TOPACTION, play a $5+ entry to get $50 in bonus cash guaranteed. This means that your initial entry does not need to win for you to receive the bonus. Remember, this entry can contain picks from across the sports world with each pick you add exponentially increasing your payout multiplier. Let's take a deeper look at how entries work in the context of the Underdog Fantasy promo code TOPACTION.
At Underdog Fantasy, there are two different ways to play: Standard or Flex. A Standard entry requires all of your picks to win to receive a payout, while a Flex doles out winnings even if you lose just one selection. However, the key difference between these two formats is the payout multiplier. Because a Standard entry is far more difficult to win, the payout multiplier is much more significant.
Take a look at the entry below as an example:
- Caleb Williams HIGHER than 69.5 Passing Yards
- Patrick Mahomes LOWER than 40.5 Passing Yards
- Avery Johnson HIGHER than 203.5 Passing Yards
Suppose I place this entry as a Standard for $10, which has a 6.6x payout multiplier. Here is what I receive with the Underdog promo code TOPACTION:
- If all picks within the entry win, I receive a $66 total payout ($56 profit + $10 entry returned) and $50 in bonus cash.
- If one or more picks within the entry lose, I receive the $50 in bonus cash only.
Remember to use the Underdog Fantasy promo code TOPACTION during registration to claim your sign-up offer.
