“A Game is Art and Education”: This is “Graph Paper Game” to learn the formula of distance. People not only can enjoy this casual game on the computer but also learn what the Pythagoras’ Theorem to calculate the distance between two-points. But “Graph Paper Game” is not just a game to learn Mathematics for young students. Moreover, I have considered how this game can inspire people to get interested in fields of math and creativity. Also, this project explores about how a casual game can be more aesthetic than functional. Not playing this game but displaying “Graph Paper Game”, people can experience and appreciate an artistic casual game. More possibility of the game is that people can use a Smartphone as a remote controller to play “Graph Paper Game” through Wi-Fi connection between a computer and Smartphone.
