method of breeding robot pet using on-line and off-line systems simulaneously

PURPOSE: A game method for rearing a robot pet by linking an on-line with an off-line is provided to make various functions be added continuously. CONSTITUTION: After connecting to a game server(S510), a user initializes a robot pet, if necessary(S520), and a feed is downloaded(S530). If a feed download is succeeded, a predetermined amount is added to a power(S540). If the user succeeds an ampul download(S550), a predetermined amount is subtracted from the power(S560). It is desirable that the subtracted amount is more than the added amount. In the case of an ampul download, only when a download is succeeded, the power value is changed. It is judged whether the changed power value is more than a predetermined value necessary for increasing an age(S570). If the changed power value is more than a predetermined value, an age of the robot pet is increased by one year(S580).
