There are two types of entries that users can play on Underdog, a standard entry or a flex entry. For a standard entry, place a 2+ leg entry, and every pick must be correct to receive winnings. The more legs in the entry, the higher the payout.
Then, there is a flex entry, where users can place a 3+ pick entry and still receive some winnings of only one leg loses. That said, the payout is lower if all of the legs hit.

NFL Week 15 Ladder Plays on Underdog
One of the most fun promotions you can check out on Underdog is the Ladders promo. With this, you can select three or more players who you think have a chance of reaching a ceiling outcome, and climbing multiple legs of a ladder.
The higher your selected players climb, the higher the payout. One note is that your payout is based on the lowest leg each player climbs. Here are some players for Sunday that we think have a chance to have big games and each leg of their ladder:
- Woody Marks Rushing Yards: 55 yards, 70 yards, 120 yards
- Brian Thomas Jr Receiving Yards: 30 yards, 47 yards, 100 yards
