The objective of this study was to investigate the impact of Video Games and their role on promoting Saudi Kids' English vocabulary retention. The study attempted to answer whether there was a statistically significant difference (a = 0.05) between the Saudi children's subjects' mean score on the English vocabulary test due to using Video Games activities in Kindergarten or not. The researcher used a random sample of (60) female Saudi children from a kindergarten in Riyadh; (30) students to represent the experimental group, and (30) students to represent the control group. In the experimental group a selected group of Video Games was used from the official site of the British Council to teach vocabulary, whereas in the control group English vocabulary was taught through traditional methods. At the end of the teaching period, the participants' performances were compared. Those children sat for a pre and post-test of vocabulary which was prepared to suite the sample's ages. ANCOVA analysis was used to analyze the quantitative data. The results indicated that the mean score of the children in the experimental group was significantly higher than those in the control group, indicating the positive effect of using Video Games in teaching English vocabulary to children. It was recommended that kindergarten teachers adopt Video Games activities in their classroom practices to improve children's English vocabulary retention. Consequently, the children's English comprehension would be improved as well.
