The low ability of students to write is due to teachers' need for more use of learning media during the learning process. So to overcome these problems, we need media to help the student learning process. This research aims to develop edutainment monopoly media and its implementation through the course review horay model. This research belongs to the type of development research which was developed using the ADDIE model. The ADDIE model comprises five research stages: analysis, design, development, implementation, and evaluation.

The results of student responses were 91.94% (very good). The practicality test results scored 99.7% (very practical). The individual trial results were 93.6 (very good). The results of the small group trials were 91% (very good).

Based on these results, monopoly edutainment media and its implementation through the course review horay model can improve students' writing skills.
