La Primitiva is one of Spain's oldest and most popular lottery games, known for its long history, generous jackpots, and significant contributions to charitable causes. Established in 1763, it has evolved into a cultural phenomenon and a beloved tradition among Spaniards. To play La Primitiva, participants select six numbers from a pool of 49. Additionally, a seventh number, known as the "Reintegro," is automatically assigned to each ticket. Matching all six main numbers plus the Reintegro wins the jackpot.
