Underdog Promo Code LABSNEWS: Build an NBA DFS Lineup Today
Use the Underdog promo code LABSNEWS to turn a $5 NBA DFS lineup into $75 in fantasy bonus entries. You can select players from any game on the slate. That includes marquee matchups like Celtics vs. Spurs and Timberwolves vs. Lakers.
Open the Underdog Fantasy DFS app and start building your NBA DFS lineup. For each player projection, choose “Higher” or “Lower” to add that selection to your entry. If you build a perfect 8-for-8 lineup, you can earn the maximum payout of up to 120x your entry.
If your lineup contains three or more picks, Underdog requires you to choose between two entry types:
- Standard: Offers the largest possible payout, but every pick in the lineup must win.
- Flex: Provides smaller payouts for perfect lineups. However, it gives you a chance to profit or receive your stake back if one pick misses.
