Chiruca, the Spanish brand of outdoor shoes, has just launched the second round of its marketing campaign on social networks. The new contest is called “Pieza a pieza,” which means “Piece by piece.” Chiruca's followers on social networks are invited to complete a puzzle online as quickly as they can. The prize is only known to those who get to the end of the puzzle. The game is available at http://chiruca.es/piezaapieza, on the Facebook page “En Marcha con Chiruca,” as well as on Twitter at @marchaschiruca and on the brand's Youtube channel “Chirucatube.” The results, including the time that it took each player to solve the puzzle, will be published with the hashtag #piensamientochiruca. The “Pieza a pieza” campaign will run until Dec. 8.
