The present study investigated the effect of using digital games on developing English spelling skills of primary students. The sample consisted of 35 (male and female) students who enrolled in the third year at Mojamaa El Maris Primary School in Luxor. To assess the participants' English spelling skills, an English spelling test was designed. Eleven digital games have been designed to develop English spelling skills of the students. To analyze the collected data, descriptive statistics were used such as Paired samples t- test, Standard deviations, Means, and Spearman rank order coefficient of correlation. Eta squared was obtained using the t-value for the differences between the means of scores to calculate the effect size of incorporating digital games (independent variable) on the participants' spelling skills (dependent variable). Findings of the study proved a remarkable improvement in the post English spelling test scores of the participants. The findings also revealed a considerable increase in the test scores on each of English spelling sub-skills, i.e., phonological awareness, visual knowledge, and orthographic awareness, favoring the post administration. Results of the present study confirmed that digital games could develop the primary students' English spelling skills. It was recommended that digital games should be used in English classrooms, especially in teaching spelling. In addition, learning through fun should be included in the educational curricula of the primary stage.
