To celebrate 100 years of McVitie’s Chocolate Biscuits, we turned Britain’s favourite teatime ritual into a nationwide game on National Biscuit Day. Six million biscuits are lost to dodgy dunks every week - so we challenged fans to prove their skills on an interactive DOOH experience. Using hand-gesture haptics, players mimicked the ultimate dunk, balancing precision and nerve to avoid the dreaded break. With 100 daily prizes, bonus rewards for near-perfect dunks, a live ‘dunkerboard’ fueling competition and social sharing baked in, McVitie’s made dunking the nation’s new sport.
