The rapid development of smartphone technology provides an opportunity for use in mathematics learning. One of the uses of smartphone technology in learning mathematics is mathematics learning games. Research has shown that mathematics learning games are generally only on numbers and are still lacking in geometry. This study aims to develop an android-based mathematics learning game on the geometry topic, i.e., congruence and similarity. This study’s research method is the Plomp development method with three stages: preliminary research, the prototyping stage, and the assessment phase. The subjects of this study were 56 seventh-grade students from the Wagir Public Junior High School in Indonesia. Six students participated in small group trials, and 50 students participated in field trials. The results showed that the Android-based learning game on congruence and similarity had been successfully developed. Experts have validated the game media with a score of 3.36, which shows that the media created are valid. The practicality tests in the small group trial resulted in a score of 3.50, while the field trial resulted in a score of 3.51. The effectiveness tests carried out in the small group trial resulted in a score of 3.36, while the field trial results had a score of 3.38. These results indicate that the learning games developed are practical and useful for use in mathematics learning. © 2021
