This application was developed specifically for the Christmas campaign of Caixa Econômica Federal bank.

"The Magic Formula of Christmas" offers children a fun adventure of hunting for the magical feelings of Christmas.

During the campaign, participants were required to download the "Fórmula Mágica CAIXA" app, available at the time on Android and iOS. They then embarked on a quest to find the positive sentiments in a specially prepared space for this super mission.
