People who enjoyed the game via mobile phone were appeared as the multi media function was added at the time of 2005. It was not proper to play the game regularly with holding two hands because the traditional mobile phone was vertically long. I came to an idea that it will be nice if the mobile phone structure can be transformed into like Nintendo and PSS during playing the game. Therefore, the proper structure for enjoying game was provided by centering the display attached at the top of the mobile phone by rotating through particular pivot. The feeling of the traditional mobile phone in its entire style was maintained to give the dramatic effect when it is changed into the game machine.
