Recent contributions proposed sonification techniques to al low people with visual impairment or blindness to extract information from images on touchscreen devices. In this con tribution we introduce Invisible Puzzle Game, an application that is aimed at performing an instrumented remote evalu ation of these sonification techniques. The aim is to reach a wide audience of both sighted and visually impaired users and to engage them, thanks to game elements, in playing over time, so that it is possible to evaluate how the perfor mance of each sonification technique is affected by practice.
