Stimulation in early childhood development is crucial, especially in social development. There are various ways to stimulate children's social development optimally, one of which is using traditional ‘piceng’ game media. The study aimed to see if traditional games improved children's social development in children aged 5-6 years. Six children aged 5–6 years were studied using quantitative, descriptive, and qualitative research methods. The sampling technique used was purposive sampling with certain limits or criteria. The instrument used was a rating scale observation sheet, and the data analysis technique used was quantitative descriptive analysis. The phases of the research involved observation (before, during, and after the treatment) and data analysis. Based on the findings, before and after using the traditional piceng game, the average pre-test score was 34.33, and the average post-test score was 51.16, with an average hypothetical value of 40. It appears that the post-test score has increased compared to the pre-test value. So, there is an increase in children's social development through the traditional piceng game. The findings imply that, to develop children's social skills, educators or parents can use the traditional Piceng game.
