Changes in antenatal gut microbiota (GM) have been associated with gestational diabetes and obesity which are influenced by diet and lifestyle. Gamification can be used as an interactive health education tool to convey this concept to the public. Thus, we designed an interactive story titled 'MoM: Microbiome of Maternity' highlighting the importance of diet and lifestyle during pregnancy. Using the 'RPG Maker MV' software, a branching narrative emphasizing flavour texts with a local flair was developed. The choice-based game narrative revolves around daily diet and lifestyle preferences in an engaging story throughout pregnancy. A graphical report is provided at predetermined intervals, highlighting the relevant details on their health and GM. A pilot evaluation was conducted using feedback surveys: Part A evaluated the knowledge on GDM, healthy diet and GM (13 items, score [more than or equal to]8 ([more than or equal to]60%) depicts adequate knowledge) and Part B evaluated the satisfaction on the game design and structure (24 items, score [more than or equal to]38 depicts satisfaction and pleasant experience). We found that the initial knowledge on the introduced health concept were inadequate (Part A score 7.67 ± 2.97). After playing 'MoM', their understanding was improved and were satisfied with the design (Part B score 42.3 ± 6.49). In conclusion, 'MoM' is an effective educational game in promoting health awareness among women.
