Online shifting of classes contributed to the extreme use of the internet and a growing majority of children started to play online games in their leisure time. Primarily, online games served the purpose of entertainment, but excessive playing has led to an addiction that raises concerns about its effects on social, emotional, physical, and academic problems. This study was planned to see the effect of addiction to online games on social-emotional and academic performance by a cross-sectional survey with 322 students of 9^th grade. Data were collected by a questionnaire and analysis revealed that there is a moderate negative effect of addiction to online gaming on social emotional well-being. The academic performance was also found negatively correlated to online gaming addiction. Hence, it can be inferred that the students more addicted to online games have had social-emotional issues and their academic performance was also poor. Teachers should motivate the students to participate in creative activities to renovate their bad routine into a good one.
