【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a play device for a graphic puzzle according to the present invention, and is a perspective view of a state in which one piece 2 is mounted on the board surface 4 and the game is started. The play equipment is composed of a base 1 and a plurality of pieces 2 having the same shape and the same color. Reference numeral 1 is a base plate, which is made of paper, synthetic resin plate, and metal plate with appropriate thickness, and has a square top surface. Reference numeral 2 denotes a piece, which is made of a synthetic resin plate and has a circular outer shape with a constant thickness. 3 is a square for moving and arranging the piece 2, which is formed in a square shape. Reference numeral 4 is a board surface, and 16 grids 3 are arranged vertically and horizontally 4 × 4, and each side is connected to form a square shape as a whole. 5 is a number for identifying the square 3, and one different number 5 from 1 to 8 is provided near the upper left part of the eight squares 3 in the upper half of the board 4 and the eight squares 3 in the lower half. Write a different number from 1 to 8 near the upper left part in bold. Moreover, two sets of the same numeral 5 are described so as to be sequentially arranged in point symmetry (however, in the drawings, in order to identify the position of the cell 3 of the same numeral 5, for the sake of explanation, 1 to 8 are different. The number 5 is indicated by the symbol 'or ", respectively.) Figures 2, 3 and 4 are perspective views showing an example of the movement and arrangement of the pieces 2 during the game, and Figure 5 shows the completed state of the game. It is a perspective view which shows an example.

According to the American mathematician Solomon W. Golomb, various shapes formed by connecting five squares so that their sides are tangent to each other are called pentominos. There is a type of seed (however, when face down, two shapes that are mirror images of one another are regarded as one type). Since its shape is similar to the letters of the alphabet, it is sometimes called F, I, L, P, N, T, U, V, W, X, Y, Z type (details of the above are above). , Published by Heibonsha Co., Ltd., edited by Shigeo Takagi, "Encyclopedia of Play Puzzle Puzzle", December 4, 1981, first edition, page 1, page 34).

The purpose of the puzzle of the present invention is to arrange five pieces 2 vertically and horizontally on the board 4 by the method described later, and pick one of the two types except the pentomino type I in the above example. Is. That is, it is considered that one square of the pentomino shape mentioned above corresponds to one square-shaped square 3 on the board 4, and the shape of the square 3 with the piece 2 is the above-mentioned, except for the I-shape. It is to arrange the pieces 2 on the board surface 4 so as to have the same shape as one of the 11 types of pentomino types (however, the pieces 2 are arranged vertically and horizontally on the board surface 4). If one piece is arranged in addition to the five pieces, the purpose of the puzzle of the present invention is not achieved).

Next, an example of a competition method will be described. The competitor prepares 10 to 12 pieces 2, puts one of them on an appropriate square 3, and then puts the piece 2 on either the upper, lower, left, or right adjacent square 3. To move. At this time, the number 5 displayed on the square 3 when the piece 2 is moved and the square 3 on the left, right, up and down around the square 3 having the same number 5 is (), and if it is an empty square 3, Put one piece each on it, and if there are pieces 2, remove those pieces 2 from the board 1. If there are multiple pieces 2 on the board 4, move one piece 2 to the next empty square 3 and then proceed with the game according to the above rules or And

For example, as shown in FIG. 1, one piece 2 is mounted on the 4 ′ square 3 and then the piece 2 of the 4 ′ square 3 is moved to the 8 ′ square 3. If so, the 5 ', 7 ", and 4" squares 3 on the upper, right, and lower sides around the 8 "square 3 are empty squares 3, so place one piece 2 on each of them. It is possible (see FIG. 2).

Next, suppose that the piece 2 of the 5 ′ square 3 is moved to the 6 ′ square 3, and the upper, right, and lower adjacent 7 ′, 5 ″ around the 6 ″ square 3 are adjacent to each other. , 2 "square 3 is an empty square 3, so you can put one piece on each of them. On the other hand, since there is a piece 2 on the 7" square 3 on the left, The piece 2 is removed to the outside of the board 1 (see FIG. 3).

If the above method is repeated and the piece 2 of the 3 ″ grid 3 is moved to the 7 ″ grid 3 from the state of FIG. 4, for example, the left side around the 7 ′ grid 3 is left. , And the square 3 on the right next to 6'and 8'is an empty square 3, so one piece 2 can be placed there respectively. On the other hand, since there are pieces 2 in the 3 ', 6 "squares 3 on the upper and lower sides, these pieces 2 are removed from the board 1 (see FIG. 5). Can be completed.

As described above, according to the present invention, the change in the arrangement pattern of the pieces 2 on the board surface 4 that repeats the generation, disappearance, division, and unification like bubbles is quite interesting.

Further, according to the present invention, although the algorithm is very simple, the way of changing them is discrete and complicated, and what type of pentomino is and what position is used. And it is unpredictable when it will be completed. Therefore, the puzzle device of the present invention never gets tired no matter how many times it is played.

In addition, if the set of pieces 2 is considered as a set of a finite number of points, various geometric patterns are formed on the board surface 4 from the point to the line and from the line to the surface as the game develops. Therefore, the purpose of the puzzle is that the shape of the square 3 with the piece 2 is the same as one of the types of pentomino (excluding type I) shown in FIG. In addition, since the five pieces 2 are arranged on the board 4, the puzzle of the present invention can cultivate a sense of modeling and a pattern for a player, especially a child.

Since the board surface 4 has two sets of corresponding cells 3 (of the same numeral 5), “one of the plurality of pieces 2 on the board surface 4 is an arbitrary piece 2, and the top, bottom, left, and right It is moved to the next empty vacant square 3. At this time, the area around the square 3 (of the same numeral 5) that matches the code of the square 3 where the piece 2 is moved is adjacent to the top, bottom, left, and right. If there is a piece 2 there, remove those pieces 2 from the board 1 ”. You can This allows the actual game to proceed.

If, for example, the code (numeral 5) of each square 3 on the board 4 is eliminated, that is, the correspondence between the squares 3 is eliminated, "the piece 2 is moved to the next empty square 3. At this time, If there is an empty square 3 around the square 3 where the piece 2 is moved, put one piece 2 on each square, and if there is a piece 2, If you apply the rule that "these pieces 2 are removed from the board 1", the initial placement is to move the piece 2 of the square 3 on the edge of the board 4 to the square 3 in the center on the upper, lower, left, and right sides. Then, in the next step, the X-type pentomino (see Fig. 6) will be completed as early as possible, and the game will not be able to withstand the refinement of time.

In this invention, various elements constituting the game, that is, the shape of the squares 3, the arrangement form of the squares 3, the positional relationship of the corresponding squares 3 (of the same numeral 5), the piece 2 to be completed As a result of diligent examination of the number (pattern) of consecutive arrangements, the scope of claims for utility models forming a part of the specification, and the conditions shown in the above examples are the most interesting game, and It turned out to be practical.

That is, regarding the shape of the squares 3, not only squares but also regular triangles or regular hexagons can be considered in consideration of how a plane like a tile is pasted, but the shape of the squares 3 When the shape is an equilateral triangle, the continuity of the pieces 2 arranged in these squares 3 is not clearly shown, such as being lined up in a jagged pattern.

On the other hand, when the shape of the square 3 is a regular hexagon, the number of adjacent squares 3 adjacent to each other around the square 3 at the center of the board 4 is diagonally right upper, diagonal left lower, and diagonal. Since there are too many left upper, diagonal lower right, left, and right adjacent 6 pieces, pieces 2 are placed in these squares 3, or pieces 2 in these squares 3 are removed from the board 1. However, it becomes complicated.

After all, when the squares 3 are formed in a square shape, since the pieces 2 arranged in these squares 3 are arranged in a straight line or bent at a right angle, the continuity can be clearly understood. ， I feel the balance in the arrangement pattern. In addition, the number of adjacent squares 3 adjacent to each other on the sides is four adjacent to the upper side, the lower side, the left side, and the right side. It is convenient to remove the piece 2 in the eye 3 from the board 1.

In the above embodiment, the grid 3 is divided into 4 × 4 vertically and horizontally, but it is also possible to increase or decrease the number of vertical or horizontal divisions to play the game. However, if the grid 3 is divided into 3 × 4 vertically or horizontally or 4 × 3, or if the number of vertical or horizontal divisions is reduced below that, the range of movement and arrangement of the pieces 2 is too narrow. ， Become crowded, the game will not change.

On the contrary, if the cells 3 are divided into 4 × 5 vertically / horizontally or 5 × 4 vertically, or if the number of vertical / horizontal sections is further increased, the range of movement and arrangement of the pieces 2 is increased. It's too big and you can't enjoy playing the game intensively. In addition, there are problems such as it takes too long to complete the pentomino. After all, if the board surface 4 is divided into 4 × 4 cells, it is necessary to concentrate on the heat, and you can enjoy the game interestingly.

In the above embodiment, eight sets of corresponding cells 3 (of the same numeral 5) are arranged point-symmetrically, but the present invention is not limited to this. However, the corresponding squares 3 (of the same numeral 5) are arranged vertically or horizontally adjacent to each other, and the piece 2 is placed on one of the squares 3 in accordance with the rule of movement and arrangement of the piece 2 described above. If it is moved, it will be necessary to remove the moved piece 2 from the board 1 at the next stage as soon as possible. Therefore, the corresponding grids 3 (of the same numeral 5) should be appropriately separated so that none of them are vertically or horizontally adjacent to each other.

In addition to pentomino, the puzzle of the present invention creates various patterns, for example, a pattern composed of four pieces 2 called tetromino and a pattern composed of six pieces 2 called hectamino. Is also possible. However, Tetromino is not sufficient in quantity for a closed flat area of 4 × 4 squares, while Hectormino is easy to use according to the rules for moving and arranging pieces 2 above. Each has its own drawbacks. Compared to these, pentomino has a good proportion (ratio to board 4) with 5 pieces of pieces 2 that make it up, and is also an optimal completion goal from the point of difficulty of the game. Is.

In the above embodiment, the piece 2 has a circular outer shape with a constant thickness, but it may be formed as a plate having an appropriate regular polygon such as a regular hexagon or regular octagon. .. Further, the corresponding grids 3 (corresponding in reference numerals, etc.) are identified by different numbers 5 from 1 to 8, but they may be identified by different characters, symbols, colors and patterns. Although the base 1 is a plate having a square shape, it may be formed as a plate having an appropriate regular polygonal shape such as a regular hexagon or regular octagon. The board surface 4 may be directly printed on the base board 1 or may be attached separately.

The above is the basis of the present invention, but as another embodiment, as shown in FIG. 7 and FIG. 8, a circular constant shape with different front and back color displays (for illustration, the front surface is white and the back surface is black) It is also possible to prepare 16 pieces of thick pieces 2 and combine them with the base 1 of the above embodiment to complete the pentomino based on the following rules (1) to (3). (1) First, all the pieces 2 are arranged on each square 3 of the board surface 4 so that the surface (white) is the top surface. (2) Next, one arbitrary piece 2 on the board 4 is reversed. At this time, the number 5 displayed on the square 3 where the piece 2 is inverted and the pieces 2 of the squares 3 adjacent to the top, bottom, left and right around the square 3 having the same number 5 are also inverted. For example, if the piece 2 of the 5 ′ square 3 is reversed from the initial arrangement of (1), then 8 ′, 6 ″, 1 ″ adjacent to the upper, left and lower sides of the 5 ″ square 3 are arranged. It is possible to invert each of the pieces 2 of the square 3 (see Fig. 7) (3) Make sure that the back surface (black) of the pieces 2 is vertically and horizontally only 5 pieces in succession and becomes the top surface. Repeat the above method (2), that is, on the back surface (black) of the piece 2, the 11 types of pentominoes (F, L, P, N, T, U, V, W, X, Y, One of the Z types) is picked up (see Fig. 8).
