Although numerous studies have documented the general effectiveness of DGBL, limited research has addressed its impact within specific pedagogical frameworks, particularly structured online environments designed for vocabulary instruction. This research investigated the impact of Education.com, a digital game-based platform, on facilitating vocabulary acquisition among Iranian intermediate EFL learners. A quasi-experimental, pre-test–post-test design was implemented with sixty participants randomly assigned to either an experimental group (n = 30), which received vocabulary instruction via Education.com, and a control group (n = 30), which followed conventional paper-based instruction. Group equivalence was confirmed through a Nelson proficiency test and a researcher-developed vocabulary pre-test. After a ten-session treatment, an independent-samples t-test displayed a statistically significant achievement in the experimental group’s post-test performance compared to the control group. The results demonstrated that the gamified and interactive affordances of Education.com significantly enhanced vocabulary learning outcomes. These findings underscore the pedagogical value of integrating structured, game-based online platforms into EFL curricula to promote more effective vocabulary achievement.</span> Digital Game-Based Learning (DGBL) Educational Technology Gamification vocabulary achievement https://www.jrtle.ir/article_238027_3171ae616af291d6627a9346b3fb0855.pdf
