  The present invention can be implemented reversibly. Reversi is usually difficult to make three-dimensional because players place stones alternately on the board. However, when the game is executed, if the player limits the surface on which the stone is placed to one surface, the two-dimensional reversi can be made three-dimensional, and a new three-dimensional game is obtained.

  In addition, the game can be enjoyed as a three-dimensional game by taking a method of playing a game by alternately stacking planes, not just making it three-dimensional.

  The three-dimensional reversi is as follows.

  The first and second hands each have one type of color (the color is set by the player), and the balls are alternately placed in a solid that is 6 elements long x 6 elements wide x 3 elements high (the number of elements is set by the player). When it is placed and finished, it is a ball arrangement game device in which the winner is the one who has the most number of own balls. When the own ball is placed, if the opponent ball is sandwiched between the own balls, the color of the opponent ball Has a rule to change the color of the ball. The sandwiching directions are front and rear, right and left, up and down, and diagonal directions.

When the game is started, a plane of 6 vertical elements × 6 horizontal elements is set, and the player's ball and the opponent's ball are placed in the center (FIG. 21).
First, if the ball is placed from the front and the opponent's ball can be pinched by the player's own ball, the opponent's ball can be changed to the player's own ball and used as the player's own ball.
Next, if the rear hand puts the ball and can hold the opponent's ball in the same manner as the first hand, it can be made the own ball.

  The place where the ball can be placed is only the place where the opponent ball can be sandwiched. If there is no place where the opponent ball can be sandwiched, the opponent player places the ball.

  If there is no place to place the ball in either the first hand or the second hand, the game for that face ends.

When the game for the height element is finished, the game is finished, and the player who has the larger number of own balls in the whole game solid becomes the winner.
If the game for the height element is not finished, create a new face either above or below the face group of the finished game, and place the player's ball and the opponent's ball in the center as with the first face. Place it one after another and continue the game. The order in which the balls are placed continues. In a game with a height element of up to 2, the ball cannot be sandwiched up and down, so the ball is changed only on the created surface.

If the game for the second surface is finished and the surface for the element with the set height is not finished, the side opposite to the newly created surface (if the created surface is on the upper side, the lower side If the previously created face is on the lower side, a new face is created on the upper side, and two balls are placed in the center in the same manner as described above. The game proceeds in the same way as described above.
The difference from the third surface to the second surface is that from the third surface, balls in the upper and lower and upper and lower diagonal directions are also sandwiched by the balls.

The present invention can be implemented reversibly.
In the case of 3D reversi, only one cross section is displayed, but by changing the direction and depth of the cross section to be displayed, the player can grasp the current situation of the ball.
FIG. 20 shows a configuration diagram of three-dimensional reversi.

  Further, FIG. 22 shows a flowchart of three-dimensional reversi.

The depth processing unit issues a display instruction for a cross section corresponding to the depth specified by the cross section display unit. The cross-section display unit displays a cross section with the instructed depth.
The rotation processing unit stores the state of the direction in which the game solid is rotated around the element set by the player in the storage device according to the instruction of the player. The rotation processing unit instructs the cross-section display unit to display a cross-section corresponding to the instructed direction. Each cross-section display unit displays a cross section in the designated direction.

  The movement processing unit stores, in the storage device, information on the position where the display position is moved while maintaining the direction of the game solid for the elements set by the player. The movement processing unit instructs each cross-section display unit to display a cross section moved by the instructed movement. Each cross-section display unit displays a cross-section at the designated position.

  The processing unit checks whether the element selected by the player is valid (by placing the player's ball, the opponent's ball can be changed to the own ball). If it is valid, the player places the ball on the indicated element, Change the opponent's ball between your balls to your ball. The surface on which the player's ball can be placed is only on the last created surface, but the other player's ball and opponent's ball are all of the existing surfaces.

The effective position display unit has a function of instructing the player where to place the ball next so that the game can proceed smoothly.
The operation record processing unit has a function of saving an operation record so that the player can improve the play technique. At the end of the game or in the middle of the game, an operation record from the start to that point is saved according to the player's instruction. The player can check the operation record from the start time. In addition, a new game can be started from the final point of operation recording or in the middle of the operation recording.

Further, the present invention can be implemented in a minesweeper. The 3D Minesweeper proceeds with the game while examining the displayed numbers and inferring the state of the 3D space.
A conventional Minesweeper is as follows.

  Mines are placed on some of the elements on the plane. The player opens each element, but loses when the element where the land mine is placed is opened. When an element without a land mine is opened, if there is a land mine in any of the eight adjacent elements (the number of elements that are not vertices or edges), the total number of land mines is displayed. When no mine is placed on an adjacent element, the element and surrounding elements without a mine are opened. Players can raise flags on elements that appear to have landmines. The player wins when the flag is set on all the elements where mines are placed. The player guesses the location of the landmine from the displayed number of landmines and opens the elements. It is also a game in which players compete for time to win.

The present invention is implemented in Minesweeper.
Place supernovas (equivalent to landmines) on some of the three-dimensional elements. Depending on the player's settings, holes are placed in some of the solid elements.

  In performing the 3D Minesweeper, the player opens each element, but loses if the element where the supernova is placed is opened. When an element on which a supernova is not placed is opened, if there is a supernova in any of the 26 adjacent elements (number of elements when not a vertex, side, or face), the total number of supernovae is displayed. When there is a supernova in an adjacent element, only the selected element is opened. If there is no supernova on an adjacent element, open all adjacent elements. If the adjacent element is not adjacent to the supernova, all adjacent elements are similarly opened. The player can change an element that seems to have a supernova to a specific color. The player wins when all supernova elements are changed to a specific color and all other elements are not changed to a specific color. The player guesses the position of the supernova from the number of displayed supernovae and opens the elements.

The hole is an element that is not covered by the game and cannot be opened by the player, and no supernova is placed. This can change the game.
When displaying a surface along one of the vertical axis, horizontal axis, or height axis, all the elements (vertices, sides, and faces) around the element specified by the player on the upper, middle, and lower three planes If not, 26 elements) are displayed, so that the player can grasp the surrounding situation. The player can grasp the state of the entire game by specifying the direction and depth of the game solid.
