to evaluate the effectiveness of the board game "Mural de Risco" (Risk Wall) on the prevention of the Human Immunodeficiency Virus/AIDS in the knowledge of people aged 50 and over in a school context.

The educational intervention took place in groups of 3 to 5 participants, with the "Mural de Risco" game, in which the participants judged the images that represented a lot, little or no risk of HIV infection. McNemar's test was applied to the distribution of correct answers.

there was a significant increase in the mean scores in the intervention group between baseline and the 30th day (p=0.001), which did not occur in the control group (p=0.953).

the game was effective in increasing the knowledge of people aged 50 and over about the prevention of the Human Immunodeficiency Virus/AIDS. Brazilian Registry of Clinical Trials: RBR-5w9tx9.
