A new visual challenge has been presented by the Readers' Challenges section of La Vanguardia, inviting participants to decipher a hidden number within a set of photographs. The images capture a tractor operating in a plowed field located in Vilobí d'Onyar, within the Selva region.

The puzzle requires viewers to not only locate the number but also deduce its value within a 30-second timeframe. Two distinct perspectives are provided: a wide-angle shot intended for locating the object and a closer view designed to help identify the specific digits. A hint was offered to assist solvers, confirming that the hidden figure consists of two digits.

Following the challenge period, the solution has been revealed. The number in question is 84, which appears on the tractor in the field. For those interested in submitting their own visual challenges to the publication, submissions can be sent via email to participacion@lavanguardia.es. Contributors must include the relevant information, video files, and author details, ensuring the subject line reads 'Retos de los Lectores'.
