With the Underdog Fantasy promo code TOPACTION, there's a 1x rollover requirement that must be completed within 14 days. For instance, if you deposit $1,000, you must place $500 in lineups on Underdog Fantasy within this 14-day window before you can withdraw any winnings tied to the 50% match.
The welcome bonus is designed to be flexible—your bonus cash is used first, before tapping into your deposit funds. Once you've exhausted all your bonus cash, the rollover requirement will be considered complete, and any winnings earned will be transferred to your available cash balance.
Use Underdog Fantasy Promo Code TOPACTION for Bills vs. Chiefs Lineups Today
After using the Underdog Fantasy promo code TOPACTION and receiving bonus cash, it's time to explore how pick’em entries work. You choose "Higher" or "Lower" based on player projections, combine your selections into a single entry, and decide between a Standard or Flex entry format.
Standard entries provide the highest payout multiplier if all picks are correct. On the other hand, Flex entries offer smaller payouts but come with a safety net—if you miss just one pick, you’ll recover part of your entry amount. Any other outcome results in a total loss.
Here is a look at a lineup example I created for Bills vs. Chiefs:
- Josh Allen HIGHER than 231.5 Passing Yards
- Xavier Worthy HIGHER than 48.5 Receiving Yards
- DeAndre Hopkins LOWER than 22.5 Receiving Yards
A Standard entry has a 6x payout multiplier, while a Flex has a 3x if you win all picks and a 1x if you go 2-for-3. Here is what I get based on the outcome of the lineup if I place it as a $10 Standard:
- If the lineup wins, I get a $60 total payout ($50 profit + $10 initial entry).
- If the lineup loses, I get nothing back but work through some of the rollover requirement with the Underdog Fantasy promo code TOPACTION.
