O Brinde do Bolo Rei - A tradition reimagined through technology
The Bolo-Rei is a Portuguese Christmas tradition with a hidden gift and a fava bean. This project brings the ritual into the digital world. Photograph a Bolo-Rei to unlock a digital gift. No Bolo-Rei? You get the fava. No prize. Just tradition.
What was the main challenge in this project?
The challenge was to translate a physical, emotional and collective ritual into a digital experience without stripping it of meaning, while preserving chance, surprise and the logic of the gift and the fava. The interaction had to be immediate and intuitive: take a photo, get a response. No downloads, no sign-ups, no friction — working seamlessly across devices and in real social contexts. At the same time, the solution needed to be robust and scalable, prepared for usage peaks and varied image quality, while maintaining visual and editorial consistency. All of this had to be ready in time for Christmas. As often happens, it’s easy to forget that Christmas arrives every year… always on December 25th.
What was your solution or approach?
The experience was designed to happen on mobile — the only device that makes sense around a Christmas table — with a simple, fast and frictionless flow. At its core is an AI model trained specifically to recognize the Bolo-Rei as an object, distinguishing it from visually similar cakes. Photographing an orange cake, for example, does not unlock a gift. You get the fava. When a Bolo-Rei is correctly identified, the system unlocks a digital gift, presented as a short animated moment inspired by the traditional objects once hidden inside the cake. The entire platform follows a mobile-first approach, lightweight and accessible, with no downloads, registrations or instructions, designed for real social settings and featuring content created specifically for the festive season and the moment in which it is discovered.
What was the outcome or impact for the client?
Starting from a creative concept developed by LOLA NORMAJEAN, the project reinterpreted a deeply rooted Portuguese Christmas ritual, adding a new layer of meaning in a contemporary digital context. The experience was organically shared by the client’s audience and generated buzz in specialised media and advertising press, extending its reach beyond the Christmas table. For Buzzvel, the project demonstrates the ability to turn a creative idea into a functional and relevant digital experience, through thoughtful UX design and mobile-first technical production, built for real-world use and informal contexts. More than a prize, the real gift was the idea that was shared.
