The Underdog promo code TOPACTION provides the perfect opportunity to claim a $75 welcome bonus and submit an NBA lineup. Our DFS expert Lee Tran confirms it's one of the best DFS offers on the market.
“Claiming the welcome bonus gives you extra entries to experiment with lineups without risking your own money, perfect for boosting your chances to win on your first slate.” – Lee Tran, DFS Expert
You can add picks from any NBA game to your Underdog lineup. The top games on tonight's schedule feature Warriors vs. Mavericks at 7:30 p.m. ET and Lakers vs. Clippers at 10 p.m. ET, both on Prime Video. Just select "Higher" or "Lower" on your player projection to add a pick to your lineup.
If your Underdog lineup has three or more picks, you choose between the Standard and Flex lineup. If you go with the Standard entry, you earn the maximum payout but only if every pick wins. The Flex lineup provides a smaller payout with a perfect entry, but you still profit or get your stake back if one pick loses.
