Lakers vs. Thunder Game 1 in the Western Conference Semifinals headlines Tuesday’s NBA Playoffs slate, tipping off at 8:30 p.m. ET on NBC. The matchup also creates a strong opportunity to use the Underdog promo code TOPACTION for additional NBA fantasy bonus entries across the second round.

Underdog Promo Code TOPACTION Details
This Underdog promo code TOPACTION offer fits best if you like DFS pick’em entries or quick fantasy contests, especially on a one-game menu like Lakers vs. Thunder (Tuesday, May 5, 8:30 p.m. ET). With a smaller player pool, your picks get tighter, correlations matter more, and late injury news can swing everything. That’s why extra entries help, since you can build around different game scripts without locking into one read.
The value is simple: $50 in bonus entries after a $5 play, available in more states than a traditional sportsbook. Use it when you want to spread exposure across a stars-and-scrubs build and a more balanced card, mixing single-entry and a few multi-entry shots. This is also a good late-window slate, so set entries earlier in the evening and keep room to adjust if news hits close to tip.

How to Use Underdog Bonus Code for Lakers vs. Thunder (8:30 p.m. ET, NBC/Peacock)
If I enter a $5 pick’em contest on Lakers vs. Thunder in Game 1 of the NBA Playoffs Semifinals, I start by signing up and entering Underdog promo code TOPACTION. If my $5 entry returns 2x on the contest payout structure, I receive $10 back total (including entry fee). If it does not cash, I lose the $5 entry fee, but I still unlock the $50 in fantasy bonus entries with a win or loss.
After that $5 play posts, I treat the $50 in fantasy bonus entries like contest-only entry fees, not cash I can withdraw. On this one-game slate, I can split it into five $10 entries across different Lakers-Thunder builds (one stars-and-scrubs, one balanced, one built around a slower pace), or go $25 on my favorite card plus five $5 entries to cover other NBA Playoff games this week.
