Reading fluency is reading a text with precision, adequate speed, and accurate intonation. This work aims to increase reading fluency by employing practices that articulate gamification through online tools such as Cokitos and Wordwall, among others. Forty students from a middle school located in the Manta canton, Manabí, Ecuador, participated in the study. The paradigm adopted was constructivist, with a quasi-experimental approach. The instruments used were a pretest-post reading fluency observation form and an expert interview. The results include an educational intervention aimed at stimulating reading fluency and the changes achieved in the participants' reading speed. It is concluded that the online articulation of Cokitos and Wordwall in pedagogical sequences with gamification contributes to improvements in students' fluency, although to be significant, they may require improvements in the conditions of technological access and stability in institutional development.
