The French train company Thalys launched an exciting promotion in 2014, featuring a unique "seat for life" offer on their train services. During my time at RESN, we developed an engaging online game called "Musical Chairs" as part of this campaign. From a diverse pool of participants, one hundred fortunate players were selected and transported to Brussels to compete in a thrilling live version of the game. In an electrifying competition, the grand prize winner received a coveted seat for life, while numerous other smaller prizes were awarded to participants. Over the course of the campaign, we achieved remarkable success, with 40,000 shares on social media and the addition of 60,000 new email addresses to the Thalys database through competition registrations.
