Therefore, accessibility in this context means that people with intellectual disabilities can easily navigate and interact in a web application. Accessibility is an essential parameter to consider in each software development phase with the Web Content Accessibility Guidelines (WCAG) 2.1. As a case study, it was applied to the Ludominga platform. Accessibility experts defined 18 guidelines to evaluate ten serious games with a manual method. This research can serve as a reference for future work related to accessibility in serious web-based games.enOpenAccessPersonas con DiscapacidadSoftwareDiscapacidad CognitivaPersonas con DiscapacidadSoftwareDiscapacidad Cognitiva
