What is the Underdog Promo Code?
The Underdog promo code TOPACTION offer is a clean on-ramp for DFS players who like pick’em entries and quick, single-game contests. You make a $5 play, and Underdog kicks back $50 in Bonus Entries, so you can test more picks and contest types without increasing your initial out-of-pocket beyond that first entry.
This is especially useful on a standalone, nationally televised spot like Nuggets vs. Spurs (Sunday, April 12, 8:30 p.m. ET on ESPN), where the player pool is tighter and ownership overlaps more. Bonus Entries let you fire multiple builds, like one safer card and one higher-upside card, and still pivot if late news changes the slate. Availability depends on eligible states listed by the operator, so check where DFS is legal before you load up.
Make NBA DFS Picks on Nuggets vs. Spurs for $50 Bonus
For Nuggets vs. Spurs (Sunday, Apr 12, 8:30 p.m. ET on ESPN), the Underdog offer is built for testing multiple angles without locking into one lineup. With the Underdog promo code TOPACTION, you make a first $5 entry, then you unlock $50 in fantasy bonus entries. Simple plan: split that $50 into five $10 entries or ten $5 entries across Nuggets-Spurs picks and the rest of the NBA slate, so you’re not stuck with one read.
Think in “night budget” terms, too. If you planned to play $60 total, you can run $10 in cash entries plus $50 in Bonus Entries, keeping your out-of-pocket smaller while still getting volume. Use that volume with intent: build a safer projections card for smaller contests, then a volatility card for bigger fields, and don’t duplicate the same picks across every entry.
