  • Patent number: 10186107
    Abstract: There is provided a gaming machine capable of providing new gaming characteristics: the number of active lines is changeable to vary a winning probability. A slot machine controls a lower image display panel having a symbol display area in which some of symbols arranged in symbol arrays are respectively rearranged in display blocks in accordance with the game. The slot machine rearranges, on a one to one basis, the symbols in the display blocks arranged in a matrix of M columns by N rows. When a predetermined condition is satisfied, the slot machine adds display blocks to the matrix in the symbol display area to form a matrix of M columns by N+? rows, and sets additional active lines in the expanded display frame, the number of the additional active lines being calculated by multiplying the number of the added rows ? by a predetermined value.

  • Patent number: 9064371
    Abstract: By rotating a lever, the upper limit of the angle of inclination and the lower limit of the angle of inclination of a movable range are detected by an inclination detection mechanism, and the upper limit of the angle of inclination and the lower limit of the angle of inclination are stored in a storage unit as the upper limit and the lower limit of the movable range. While a game is being run, the angle of inclination of the lever is detected when the lever is rotated. Whether the angle of inclination falls within the movable range is determined. When the angle is larger than the movable range, the upper limit of the angle of inclination is updated with the angle of inclination. When the angle is smaller than the movable range, the lower limit of the angle of inclination is updated with the angle of inclination.
