Fox Sports and CBS Sports both highlight Underdog Fantasy promo codes that offer users a bonus amount after making a small initial play. In each case, the promotion centers on playing $5 and receiving $50 in bonus entries (or bonus cash, depending on the wording in the outlet’s description).
CBS Sports says the offer is available as of August 20 and directs users to the “Underdog Prediction Picks” product within the Underdog app. It provides a specific code, “CBSSPORTS2,” paired with the “Play $5, Get $50 Bonus Entries” language. Fox Sports similarly promotes a $5-to-$50 benefit but uses a different promo code—“FOXSPORTS”—and describes the reward as “bonus cash,” while also referencing how to claim the code and use the Underdog app.
Both outlets frame the promotion as an in-app promotion tied to making an initial $5 play, though they differ slightly in product labeling and reward terminology.
