This research is motivated by the challenge given by the Industry 4.0 era to increase the high order thinking skill of elementary schools' students thus it is necessary to develop math question used as a reference for further learning development. This study aims to develop test questions based on high order thinking skills (HOTS) to optimize the level of geometric thinking of elementary school students by using Edugames regarding the subject of area and circumference of a plane figure. This is development research using the Design-Based Research method. The results of this study are test questions based on high order thinking skills optimizing the level of geometric thinking of elementary school students with the use of Edugames on the subject regarding area and circumference of a plane figure. The implication of this study is as a basis for knowing students' high order thinking skills in optimizing the geometric thinking abilities of elementary school students.
