Abstract: In a game system having a monitor, an input unit for supplying a signal corresponding to a player's operation, and a game controller for executing a predetermined card game on a game screen of the monitor with reference to the signal supplied from the input unit, the game controller decides a plurality of cards displayed on the game screen in a matrix. The game controller sets the number of lines of a plurality of lines formed by the cards on the game screen, each as an effective line and all of which are in a single, common direction, depending on the value of a play a player sets by operating the input device, and controls a dividend for the player according to a combination of the cards on any of the effective line and a combination of the cards in a direction different from the direction of the effective lines.

Abstract: A video game machine has a mechanism extracting balls, a display unit having a display area which displays a matrix composed of boxes, and a CPU. The CPU implements a function enabling the player to appoint a ball type in terms of color and number to boxes of a second line of the matrix. A function is provided for automatically displaying, in the first and third lines of the matrix, ball marks correlated to the ball marks displayed in the second line, such that the color sequences of the ball marks in the first and third lines are the same as that in the second line and such that numerals greater and smaller by one than a numeral in a box of the second line appear in the third and the first lines in each column of the matrix. Further provided is a function for determining whether or not the numeral of the extracted ball coincides with the numeral of any ball mark on the display and a function for changing the mode of display of the box having the coincident numeral.
