Underdog Fantasy Promo Code WSNPLAY: Up to $1,000 in Bonus Cash + a Shot at $1,000,000 - October 1, 2026

Use Underdog Fantasy promo code WSNPLAY to get a first-deposit match of up to $1,000 in Bonus Cash, plus access to Keep Your Million, a free-to-play game that starts you with a virtual $1,000,000 pot. Bonus Cash works on fantasy entries, and anything those entries win is yours to withdraw.

Underdog Fantasy Promo Code for October 1, 2026

The table below covers the core terms of the Underdog Fantasy welcome offer as of October, 2026.

Underdog Fantasy Promo Code Offer Overview

The Underdog Fantasy welcome offer matches your first deposit in Bonus Cash, up to $1,000, and adds Keep Your Million. The match kicks in on a first deposit of $10 or more, and the Bonus Cash lands in your account within 72 hours. It only works on fantasy entries with a payout multiplier of 2x or higher, so lower-paying entries have to be played with your own money.

Before the bonus portion becomes withdrawable, you have to enter contests worth your deposit and your bonus combined, and you have 14 days to do it. Any Bonus Cash left unplayed after that is forfeited. Winnings are a different story: anything you win from entries paid with Bonus Cash can be withdrawn right away, even before the playthrough is met.

Say you deposit $100. Underdog adds $50 in Bonus Cash, giving you $150 to play with and 14 days to enter $150 worth of contests. Collecting the full $1,000 takes a $2,000 deposit and $3,000 in entries inside the same window.

Keep Your Million works differently. You start with a virtual $1,000,000 pot and answer 20 player prop questions, splitting your pot between the two sides of each one. You keep whatever sits on the winning side, the game ends if your pot hits $0, and whatever survives all 20 questions is paid out as bonus funds, not cash. You have 7 days after signing up to make the $10 deposit that unlocks the game, then 60 days to finish it.

Underdog presents its welcome offers at signup. When they appear as a Choose Your Offer selection, you pick one, and choosing the deposit match rules out Keep Your Million.

New users also get a Money Back Guarantee on their first contest entry. If you're unhappy with the product, Underdog refunds up to $100 within 48 hours of that first entry, as long as you close your account permanently and haven't withdrawn any winnings.

Underdog Fantasy Promo Code Not Working?

A failed Underdog Fantasy promo code comes down to one of seven causes.

• Code missing at signup: WSNPLAY has to go in during registration, before your account is complete.

• Existing or duplicate account: the offer is one per person, and duplicate accounts forfeit their bonus.

• Deposit under $10: the match only triggers on a first deposit of $10 or more.

• Bonus not showing yet: Bonus Cash takes up to 72 hours to credit after your deposit clears.

• Entry below 2x: Bonus Cash won't apply to entries with a payout multiplier under 2x.

• Keep Your Million missing: it only appears on the latest version of the app, and not if you chose a different welcome offer.

• Ineligible state or self-exclusion: fantasy contests aren't available in every state, and players on a self-exclusion list or active cool-off can't claim the offer.

Underdog Fantasy Promos for Existing Users

Underdog runs three types of promos for existing players: always-on protection, limited-time tokens, and sport-specific contests. Each works as follows.

• Rescues (always on): if a player on the Higher side of your entry leaves after the first half, your entry is refunded and you get a Gimme Pick the next day. In MLB, hitters qualify if they started and exited before their third plate appearance, capped at 7 rescues per player per season. Pitchers aren't eligible.

• Gimme Pick tokens (limited time): one pick on your entry is graded as a win regardless of how the player performs.

• No Sweat tokens (limited time): if your Pick'em entry loses, you get your entry fee back as promo credit.

• Boost tokens (limited time): raise the profit on a winning Pick'em entry by a set amount.

• Discount tokens (limited time): lower a player's projection by a set amount.

• Bonus Entry tokens (limited time): submit a Pick'em entry at no cost, with the profit paid in cash if it wins.

• MLB Split the Pot (when running): pick the pitcher with the most strikeouts that day and share a $50,000 pool in bonus entries with everyone who picked him, whether or not your entry wins.

Winnings from token promos arrive as promo credit with a 1x playthrough, and unused tokens expire at the end of their promo period.
