Underdog DFS Entry Types
When placing entries on Underdog Fantasy, you have two primary options, allowing you to manage risk based on your confidence level:
- Standard Entry: For maximum potential payouts, you must select 2 or more player picks. To win the maximum advertised payout, every selection in your entry must be correct.
- Flex Entry: If you select 3 or more picks, you gain the option to “flex” your entry. This strategy means you can still receive winnings, albeit reduced, even if one or two of your selections are incorrect.
With $50 in bonus entries available, you have ample opportunity to test out both standard and flex entry options for the NFL preseason kickoff featuring the Arizona Cardinals and the Las Vegas Raiders and other games on deck tonight.
