Main aim of the game is to make students think about analytical coordinate system. It is important to understand because, basis of the geometry includes it. At 7th grade, students learn how to analyse coordinate system deeply and unit fractions on number line. At 8th grade, they are expected to good at the analytic coordinate. That is, they need to be internalized the concept of coordinate system. Students can play this game after immediate learning of coordinate system to make practice about the topic.
