Underdog Missouri Fantasy Contests
Not all of Underdog’s contests are available in Missouri, as the state’s unique fantasy landscape dictates which game formats are allowed.
Here’s a closer look at the Underdog contests available in Missouri:
Champions
Missouri has a ban on traditional against-the-house pick’em games, but Underdog’s answer is its Champions contest.
This game format is a peer-to-peer version of pick’em that allows users to make Higher/Lower picks while ensuring Underdog is compliant with Missouri DFS laws. Champions is separate from Underdog’s traditional pick’em games, the latter being available in states where DFS regulations are more lax.
Enter Champions mode and build a lineup of 2-8 athletes by picking whether they’ll get Higher or Lower for projected stats.
For instance, a lineup featuring Missouri athletes might look like:
- Patrick Mahomes for Higher than 1.5 Passing Touchdowns
- Rashee Rice for Higher Than 76.5 Receiving Yards
- Philip Broberg for Higher than 0.5 Goals
You can make Champions picks in Missouri on athletes in the following sports/leagues:
- NFL
- NBA
- MLB
- NHL
- College football and basketball
- Tennis
- Soccer
- Esports
- Counter-Strike
- UFC
- PGA
- Boxing
- World Supercross
- USAC Racing
- Valorant
- F1
- World Jai-Alai League
- Darts
- Cricket
Drafts
Underdog Missouri also has Drafts contests, which is the standard across all live Underdog states. The format covers everything from football and basketball to baseball, soccer, tennis, and golf.
Daily Drafts allow users to make 4-player lineups for a slate or the whole day. It’s a relatively low-commitment way to play, as the drafts are fast and can result in same-day payouts.
If you’re looking to play season-long fantasy, Underdog MO has Best Ball. It’s another low-commitment way to play, as there’s no roster management after you draft your team at the beginning of the season.
Additionally, Underdog MO hosts Tournaments with entry fees and prizes that cater to all DFS skill levels.
