An information processing apparatus erases, on the basis of a chained state of a plurality of pieces arranged on a game field, the pieces in the chained state. The arrangement of the pieces in the game field is controlled such that, in a predetermined region on the game field, an odd number of pieces and an even number of pieces are alternately arranged on imaginary lines in an advancing direction on the game field. For example, the information processing apparatus erases a serial piece group formed as a chain by determining, starting from operation for any one piece on the imaginary line corresponding to a frontmost row among the imaginary lines, whether a piece of a same kind as the one piece is present in left and right pieces adjacent to the one piece present on a next imaginary line in the advancing direction from the operated one piece.
