Display control is made so that meteor blocks ( 101 - 104 ) falling from the outer space are piled up on the surface of earth. When the player operates a cursor ( 106 ) for piled up meteor blocks ( 105 ) to designate them as objects to be operated, and presses a button, the meteor blocks are vertically re-arranged. When the meteor blocks of the same type line up as a result of re arranging, they can be ignited and launched. When the meteor blocks rise up to the outer space, they can be cleared. On the other hand, when the meteor blocks stall halfway, they cannot be cleared, and fall on the surface of earth again.
