Prepare for Saturday’s World Cup slate with Qatar vs. Switzerland at 3 p.m. ET on FOX from Levi's Stadium in Santa Clara, California, followed by Brazil vs. Morocco at 6 p.m. ET on FOX from MetLife Stadium in East Rutherford, New Jersey. Ahead of both matches, new users can claim the newest Underdog promo code TOPACTION and play $5 to get $50 in fantasy bonus entries.
Enter the Underdog bonus code TOPACTION at sign-up, make a $5 play in the fantasy app, and those $50 in fantasy bonus entries land in your account for more soccer picks and lineup builds. This is for new users who are 18+ and located in AL, AZ, AK, CA, CO, FL, GA, IL, IN, KS, KY, MA, MN, MS, NH, NC, OK, OR, RI, TN, VA, DC, WV, and WY.
Underdog Promo Code TOPACTION Offer Overview
The newest Underdog promo code is TOPACTION and unlocks $50 in fantasy bonus entries when you play your $5 first entry. Underdog is a leading DFS platform available in AL, AK, AR, CA, DC, FL, GA, IL, IN, KS, ME, MS, MN, NE, NM, NC, ND, OK, OR, RI, SC, SD, TX, VT, VA, UT, WI, and WY.
This Underdog welcome offer is built for DFS players who enjoy pick’em-style entries and want more chances to build around a World Cup slate without increasing that first spend. Make a $5 play in the fantasy app, and you unlock $50 in fantasy bonus entries to use across different contest builds for Qatar vs. Switzerland, Brazil vs. Morocco, or other 2026 World Cup matches.
Saturday’s schedule gives users two separate World Cup windows to build around. Qatar vs. Switzerland opens the slate at 3 p.m. ET on FOX, while Brazil vs. Morocco follows at 6 p.m. ET on FOX. That gives new users time to use the bonus entries across multiple plays, compare different player projections, or split exposure between the early match and the Brazil vs. Morocco showcase.
How to Use Underdog Offer on Saturday’s World Cup Slate
Here’s how I’d use the Underdog offer in a real Saturday World Cup lineup. If I enter a $5 pick’em contest for Qatar vs. Switzerland or Brazil vs. Morocco, I start by signing up and entering the Underdog promo code TOPACTION. If my $5 entry returns 2x on the contest payout structure, I receive $10 back total, including stake. If it does not cash, I lose the $5 entry fee, and I still unlock $50 in Bonus Entries after that $5 play posts because the offer is Play $5, Get $50 in Bonus Entries.
Once the $50 in Bonus Entries hits, I treat it like extra entries for separate eligible contests, not cash I can withdraw. For example, I can spread the bonus across multiple World Cup builds instead of duplicating the same card:
- 10 x $5 bonus entries across different player picks
- 5 x $10 bonus entries with tighter World Cup builds
If I want more exposure to the full Saturday slate, I can use one build around Qatar vs. Switzerland and another around Brazil vs. Morocco. That creates more flexibility than loading soccer picks from both games into one entry, especially with two separate FOX windows and different match scripts.
