  • Publication number: 20220005325
    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.

  • Patent number: 11161582
    Abstract: A vessel propulsion apparatus includes a first transmission path that transmits the power of an engine to a propeller shaft, a second transmission path that transmits the power of a motor to the propeller shaft, and a controller. A first clutch cuts off the power transmission of the first transmission path in a first disconnection state, and permits the power transmission of the first transmission path in a first connection state. A second clutch cuts off the power transmission of the second transmission path in a second disconnection state, and permits the power transmission of the second transmission path in a second connection state. The controller executes tuning control of both the engine and the motor when the first clutch is switched between the first disconnection state and the first connection state and when the second clutch is switched between the second connection state and the second disconnection state.
