Underdog Promo Code LABSNEWS: Create a Thursday CBB DFS Lineup for First Round
Take advantage of the Underdog promo code LABSNEWS to turn a $5 CBB DFS entry into $50 in fantasy bonus entries while building lineups for the First Round slate. You can mix and match players from all available games to create a lineup tailored to your projections.

Getting started is simple — open the Underdog Fantasy app, select player props, and choose “Higher” or “Lower” for each pick. If you hit a perfect 8-for-8 entry, payouts can reach up to 120x, giving your lineup massive upside.
For entries with three or more picks, you’ll choose between Standard (higher payouts, all picks must hit) or Flex (lower payouts, but allows for one miss while still returning value).
Below is an example of my expert CBB DFS lineup for the Round of 64 games on Thursday, March 19. Use the Underdog promo code LABSNEWS to claim the $50 FantasyLabs welcome bonus. Then, building your own CBB lineup today.
