Boom launches $40 free lineup bonus for new users on July 4 MLB and World Cup games

Boom offers a welcome promotion for new customers who are 18 + and located in eligible U.S. states. After creating an account, depositing at least $10 and placing a $5 entry, users receive $40 in free daily‑fantasy lineups. The offer applies to the July 4 slate of Major League Baseball contests—including matchups such as the Mets vs. Braves, Padres vs. Dodgers and Cardinals vs. Cubs—and to the FIFA World Cup Round‑of‑16 games, for example Canada vs. Morocco and Paraguay vs. France.

To claim the bonus, users must enter the specific promo code (e.g., BROAD, SOUTH, or WTOP40) during registration, meet the minimum deposit, and place the qualifying $5 play. The free lineups can be used on any MLB or World Cup prop contests on the same day.
