San Antonio Spurs vs. Oklahoma City Thunder Game 1 tips off at 8:30 p.m. ET on NBC/Peacock tonight, Monday, May 18, 2026 in the Western Conference Finals. The Underdog promo code lands right as you’re building lineups: play $5 and unlock $50 in bonus entries with LABSNEWS.
That $50 in bonus entries can carry into more NBA action, plus NHL and MLB contests on the Underdog app. New users who are 18+ can sign up now in AL, AK, AR, CA, DC, FL, GA, IL, IN, KS, ME, MS, MN, NE, NM, NC, ND, OK, OR, RI, SC, SD, TX, UT, VA, VT, WI, and WY.
What is the Underdog Promo Code?
The Underdog promo code is LABSNEWS and unlocks the Play $5, Get $50 in Fantasy Bonus Entries offer. This setup lets you test more than one angle without committing to a single lineup. Play $5, then use $50 in bonus entries across the lobby, whether you’re building single-entry or running multiple cards.
With a late start like Spurs–Thunder (8:30 p.m. ET), news can swing the best picks in a hurry, and having extra entries ready makes it easier to pivot when a scratch or rotation tweak drops. That’s where the Underdog offer comes through: it gives you room to try formats and rebalance exposure across NBA, plus whatever else you’re playing that night, after your first $5 play with code LABSNEWS.
Use any sign-up link on this page to claim the offer from Underdog, one of the best DFS apps available on the market.

The whole move is starting small, then letting the bonus entries do the volume. Say I enter a $5 pick’em contest on San Antonio Spurs vs. Oklahoma City Thunder Game 1, I start by signing up and entering Underdog promo code LABSNEWS. 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, and after that qualifying play posts, Underdog credits me with $50 in fantasy bonus entries (contest-only entry credit) to use on separate eligible contests including the NHL Game 7 between the Canadiens and Sabres at 7:30 p.m. ET.
Now I treat that $50 like a second slate bankroll and decide how much variance I want. Bigger single entries swing more. Small entries let me test alternate player combos and game scripts without one build deciding my night. I’ll usually keep my personal budget ($50–$100) for my highest-confidence builds, then use bonus entries for secondary builds and pivots. Here’s a potential way to split your deposited funds and bonus:
| Scenario | Contest Type | Sport | Entry Fee | # of Entries | Total Bonus Used |
|---|---|---|---|---|---|
| Conservative | Pick’em | NBA | $20 | 1 | $20 |
| Conservative | Pick’em | NHL | $15 | 1 | $15 |
| Conservative | Pick’em | MLB | $15 | 1 | $15 |
| Spread | Pick’em | NBA | $10 | 2 | $20 |
| Spread | Pick’em | NHL | $10 | 2 | $20 |
| Spread | Pick’em | MLB | $10 | 1 | $10 |
Must be 18+ (19+ in AL, NE; 19+ in CO for some games; 21+ in AZ, MA, and VA) and present in a state where Underdog Fantasy operates. Terms apply. Offer not valid in MD, MI, NJ, NY, OH, and PA.
