Introduction: A lack of vocabulary poses a major barrier to mastering English, often leading to communication challenges. Technology can support and facilitate the teaching-learning process, notably in the acquisition of a foreign language. Thus, this research explores the impact of Educaplay, on vocabulary acquisition among EFL high school students in southern Ecuador. Methodology: This study applied a quasi-experimental design, with a sample of 60 high school students, selected through a purposeful method. To collect data a pre-test, post-test, an observation checklist, and graded vocabulary activities were employed. The significance was measured with t-student and ANOVA. Results: Educaplay evidenced to be an effective technological tool to support students' retention and improvement of vocabulary as shown by the p-value of 4.86e-15 and the F-value (49.000) and p-values (0.000). Discussion: Implementing interactive and engaging activities through Educaplay and aligned with the teacher's guidance allowed participants to increase their vocabulary, thus they understood when and how to use different terms and the correct spelling of these words. Conclusion: Participants improved their vocabulary proficiency and increased their motivation to study this language. Additionally, the findings unveil that incorporating Educaplay in the classroom promoted a productive and interactive learning environment.
