You don’t have to wait long to get started—sign up now using the Underdog Missouri promo code TOPACTION, and you can start building your lineup as soon as tomorrow. Once it’s time, just pick “Higher” or “Lower” on each player projection to complete your lineup.
The more picks you add, the bigger your potential payout. Underdog Missouri lets you include up to six picks per lineup. You can mix and match picks from any sport, though the most popular options in Missouri are the NFL, college football, and NHL.
If your lineup has three or more picks, you must choose between a Standard or Flex entry:
- Standard lineup: Offers the largest payout but requires all picks to win.
- Flex entry: Pays less if all picks are correct, but still allows you to profit or get your stake back even if one pick loses.
