Use Underdog Promo Code TOPACTION on College Basketball DFS Lineup
Right now, you can use the Underdog promo code TOPACTION to unlock a $50 welcome bonus for March Madness. DFS expert Nick Goodling breaks down why this is the top college basketball DFS promo available right now.
“If you’re playing college basketball DFS in March, there’s no reason not to grab the $50 bonus with code TOPACTION. It’s great value that instantly boosts your lineup upside.”
To build your lineup, select “Higher” or “Lower” on player projections. If you add three or more picks, you choose between a Standard or Flex lineup. Standard entries offer the highest payout but require every pick to win, while Flex entries provide a smaller payout with a perfect lineup or return your stake if one pick misses.
