  • GAMING MACHINE, METHOD FOR PROVIDING A GAME, AND A PROGRAM
    Publication number: 20190362605
    Abstract: To provide a gaming machine that can provide a novel game in which the game progression is varied, a method, and a program for providing a game. In the gaming machine 1, the symbol blocks B1 and B2 displayed in the block display region 66 move in the directions D1 and D2, which intersect in the direction of reel rotation, when moving in the symbol display region 60. That is, the symbol blocks B1 and B2 are added to the movement in the direction of reel rotation, and also move in a direction orthogonal to the direction of reel rotation. Therefore, compared to a case in which a symbol block moves in the direction of reel rotation, prediction by a player of the positions where the symbol blocks B1 and B2 are finally disposed is difficult.

  • MEMS device
    Patent number: 10396752
    Abstract: A MEMS device that suppresses variations in a resistance value caused by contracting vibrations in a direction in which a holding portion extends. The MEMS device includes a frame, a rectangular plate that receives an input of a driving signal, and holding portions that anchor the rectangular plate to the frame. The frame and the rectangular plate are both rectangular in shape. The holding portions are provided extending toward the frame from central areas of the opposing sides of the rectangular plate, and anchor the rectangular plate to the frame. A resistive film is formed in a region that follows a straight line connecting the holding portions that anchor the rectangular plate to the frame and that corresponds to no more than half a maximum displacement from a vibration distribution.

  • GAMING MACHINE, METHOD AND PROGRAM FOR PROVIDING A GAME
    Publication number: 20190172321
    Abstract: To provide a gaming machine that can provide a new type of game that maintains or improves the interest of a player, and a method and program for providing a game. In the gaming machine 1, by removing symbols of a particular type and moving a following symbol, the ratio of symbols of types other than the particular type becomes higher in the symbol array formed on the display unit 27, and it is easier for the symbol array to configure a winning combination. Because the chance of winning is higher after the particular type of symbol is removed in this manner, it is possible to provide a new type of game where the interest of the player can be maintained or improved after the symbols are removed.
