Underdog Fantasy Promo Code TOPACTION: Play $5, Get $50 in Bonus Cash for NCAAF & NFL
Sign up today with the Underdog Fantasy promo code TOPACTION and play a $5+ initial entry to get $50 in bonus cash. Use this bonus to play entries on your favorite teams and players, including any involved in Week 3 college football and NFL games. Click on the sign-up module below to get started today.
At Underdog Fantasy, there are two formats available to choose between to play your first entry. A Standard entry requires that you win all of your selections to receive a payout. The Standard entry payout is much more significant than the alternative, which is called a Flex entry. A Flex entry yields a smaller payout than the Standard for going perfect, but the key difference is that you still get a small payout back if you lose a single pick.
Here is a look at an entry I created with the Underdog promo code TOPACTION that combines Week 3 CFB and NFL picks:
- John Mateer HIGHER than 255.5 Passing Yards
- Jonathan Taylor HIGHER than 88.5 Rushing Yards
- Jaylen Warren HIGHER than 0.5 Rushing + Receiving Touchdowns
Suppose I place the entry above as a $5 Standard (6.3x multiplier) for my initial entry with the Underdog Fantasy promo code TOPACTION:
- If all of my picks win, I receive a $31.50 total payout ($26.50 profit + $5 entry back) and $50 in bonus cash.
- If one or more of my picks lose, I receive the $50 in bonus cash only.
