Within the UK's Black-Caribbean community, it's not just uncomfortable for older and younger generations to have candid conversations on family health history; it’s considered culturally taboo. Decades of discrimination and systemic health inequities have contributed to this minority’s distrust of genomics healthcare and medicine. But the silence is costing lives. 65% of UK Caribbeans die from genetically linked conditions such as cancer and heart disease. Yet, knowledge is power. Many diseases are preventable and treatable if caught early – and if each generation openly shares their family health history in time. Genomics England and the University of Cambridge challenged us to create a new medium that would encourage resistant generations of Caribbeans to talk to one another about personal health and conditions that might run in the family. The new concept would be piloted in London, with the goal of scaling it later with additional partners and funding. Our first step was to take a deep dive into Caribbean culture and family traditions. Upon studying the patois dialect, we discovered an island social behavior called “liming" (in Western terms, the equivalent of “chilling and hanging out" over good conversation and laughter). Now, we just needed a novel new medium to make liming on family health matters feel safe and natural. We didn't turn to tech or AI for answers. Instead, we found it in an unexpected Caribbean game tradition – dominoes. But not just any dominoes. We designed a colourful bespoke set exuding island culture – and the first dominoes to feature scientifically derived questions engraved on pieces to prompt health-related conversations during play. A UK Caribbean designer created six different colour ways for our dominoes pieces, taking inspiration from 1950’s Caribbean homes. Our questions were printed in the iconic Empire Windrush font to celebrate the first Caribbean immigrants. A film, starring a first-generation UK Caribbean grandmother playing with her grandson, launched our set. OOH posters with a QR code to watch the film brought it to transit locations in Caribbean neighbourhoods. The game is now in local London community centres, cafes and churches. The pilot reached 48% of London's 300,000 Black Caribbeans. 84% exposed said they are more likely to talk about health issues. Our dominos have been officially adopted by the UK's National Health Service as an innovative new tool to drive critical health conversations.
