The lowering costs of DNA sequencing and the diffusion of numerous Direct to Consumer Genetic Testing (DTC-GT) services have made genetic testing easily available to the general public who can buy them without any medical prescription or consultation. Nevertheless, the knowledge required to understand the provided results and their implications is still scarce in the general public. Starting from these considerations, we developed two mini-games and one serious game to increase people genetic literacy through experiential learning. The three games were tested for usability on a sample of 30 participants, 10 for each game, who were asked to report any positive or negative issue related to the games and to fulfill the Game Experience Questionnaire in order to evaluate their playing experience. Results from the three games show that players experienced moderate levels of immersion and flow, low levels of negative sensations, and a prevalence of positive emotions. In general, these encouraging results suggest that the proposed games are suitable to transmit genetic notions to the general public.
