The present invention provides a drawing machine and a game apparatus using the same by which it is easier to give the participants of the drawing an impression like drawing is carried out fairly when the computer drawing in which a winning-probability of each of drawing-objects is changed is carried out.A drawing machine for determining a winning-object from a plurality of drawing-objects includes: a winning-probability data storage unit for storing winning-probability data showing respective winning-probabilities of the plurality of drawing-objects; a drawing unit for carrying out a drawing in accordance with the winning-probability of each of the drawing-objects determined by the winning-probability data stored in the winning-probability data storage unit and determining a winning-object from the plurality of drawing-objects; a winning-probability data changing unit for changing the winning-probability data stored in the winning-probability data storage unit; a winning-probability image displaying unit for displaying a winning-probability image showing the winning-probability of each of the drawing-objects determined by the winning-probability data stored in the winning-probability data storage unit; and a winning-probability displaying control unit for changing the winning-probability image displayed on the winning-probability image displaying unit, when the winning-probability data changing unit changes the winning-probability data, so as to correspond to the changed winning-probability data.
