A method for expressing a user emotion during game play comprises displaying an emotion image received from an opponent terminal on a display of a terminal in which a game is played; displaying at least two emotion menus with respect to the displayed emotion image; making a first selection of an emotion type based on a user selection signal for any one of the displayed at least two emotion menus; making a second selection of an emotional scale based on a distance between a location on the display where the user selection signal is generated and the emotion image; changing the emotion image based on the first selected emotion type and the second selected emotional scale; and generating the changed emotion image into a response emotion image and transmitting the response emotion image to the opponent terminal.
