Underdog Promo Code LABSNEWS: Create a Tuesday NBA DFS Lineup
Use the Underdog promo code LABSNEWS to turn a $5 NBA DFS entry into $50 in fantasy bonus entries. You can build your lineup using players from any matchup on the slate, including high-profile games like Cavs vs. Bucks and 76ers vs. Nuggets.
Open the Underdog Fantasy DFS app and start creating your lineup by selecting player projections. For each pick, choose “Higher” or “Lower” to add that player to your entry. If you manage to hit a perfect 8-for-8 lineup, the payout can reach up to 120x your entry.
When building a lineup with three or more selections, you’ll choose between two entry formats:
- Standard: Offers the highest possible payout, but every pick must hit for the entry to win.
- Flex: Provides smaller payouts for perfect entries. However, it allows you to still profit or get your stake back if one pick misses.
Below is an example of my expert NBA DFS lineup for Tuesday, March 17. Use the Underdog promo code LABSNEWS to claim the $50 FantasyLabs welcome bonus and start building your own NBA lineup today.
