Abstract

PROBLEM TO BE SOLVED: To vary a difficulty level in a three-dimensional puzzle called Rubik's Cube without changing its cubic structure of 3×3×3, 4×4×4, or the like.SOLUTION: A Rubik's Cube is so structured that each cube contains a ball and the sides of each cube are painted in a single color, for example, transparently. Balls of types equal to the number of balls used in a single plane are prepared. When all types of balls are included in each plane, the puzzle is completed. Though the solution is similar to the solution for the Rubik's Cube, the difficulty level increases since it becomes difficult to imagine the finished form.

Description

  The present invention relates to a three-dimensional puzzle, and more particularly to a completed form that is a solution to a puzzle.

  Conventionally, there is a three-dimensional puzzle called a Rubik's cube. In general, six sides of a cube are color-coded into six colors. Some of them display pictures, numbers, letters, etc. instead of color-coded. In addition to a 3 × 3 × 3 cubic structure, there are various structures such as 4 × 4 × 4.

  However, the display of a picture or the like is the same as the color-coded puzzle difficulty level. The gist of the present invention is to change the difficulty without changing the cubic structure such as 3 × 3 × 3.

  As shown in FIG. 1, the present invention has a structure in which a sphere is contained in each small cube. The sides of each cube are not color-coded and are the same color and do not help solve the puzzle.

  The number of these spheres is 27 of 3 × 3 × 3. However, since a sphere cannot be placed at the center of this cube puzzle, it cannot be seen even if placed, so in reality it is 26. Each of these spheres is marked with numbers 1-9. Three each of 1-9 are designated. Since there are actually 26, only a certain number is two.

  This solid puzzle is completed when all the numbers 1 to 9 are included in any 3 × 3 plane as shown in FIG.

  These spheres are made to have different colors for each of 1-9. This 3D puzzle can be said to be complete if all 9 colors are included in any 3x3 plane.

Suitable for this color coding is a sphere used for billiard 9 balls.
In this three-dimensional puzzle, a sphere with the same color and number notation as 9 balls is used.

  The solving method of the three-dimensional puzzle of the present invention is the same as that of a normal Rubik's cube, but is different in that it is difficult to imagine a completed form. The difficulty increases as much as the completed form must be considered.

  In the completed form as shown in FIG. 2, it is only necessary to complete one surface in which 1 to 9 are arranged in order first, and then it is relatively easy to imagine the completed form. However, a completed product as shown in FIG. 3 can also be prepared. In this case, it is necessary to complete the first surface after considering the final completed product. As described above, two levels of difficulty can be prepared in the three-dimensional puzzle of the present invention.

  Conventionally, there is a three-dimensional puzzle that is completed when numbers are written on each side of a cube and 1 to 9 are arranged on all six sides. In this case, the completed form is easy to imagine to some extent, such as the orientation of the numbers displayed when completed, and the difficulty is close to that of a normal Rubik's cube. If the same level of difficulty as the three-dimensional puzzle of the present invention is used, the numbers displayed when completed will be mixed horizontally and upside down, and the completed form will not be beautiful. By using the sphere according to the present invention, the difficulty level of the puzzle can be changed while maintaining the cleanness of the completed form.

  The three-dimensional puzzle of the present invention uses balls of the same color as the nine balls of billiards. This fits the taste of the person who enjoys the puzzle, and the appearance when the puzzle is completed is also beautiful.

  Billiard balls can also be used in the case of a 4 × 4 × 4 cubic structure. In this case, there are 16 types of balls, but there are 1-15 types of billiards and 16 types of white balls, and all can be used exactly.

  FIG. 4 shows an example of a completed form in the case of 4 × 4 × 4. In the case of a 4 × 4 × 4 cubic structure, a completed shape can be prepared in which two surfaces 1 to 15 and white balls are arranged in order.

  The structure of the three-dimensional puzzle of the present invention is the same as that of a normal Rubik's cube. The difference is that a sphere is put in each cube so that it can be seen, and the side surface of the cube is the same color such as transparent so that it cannot be distinguished.

  There is a place that is not actually a sphere about what has been described as a sphere. There are places where there is only about half the space of a cube in the corner, such as the center when viewed on a 3x3 surface. Instead of a small sphere, a hemisphere is attached here.

Claims (2)

  In a three-dimensional puzzle called Rubik's Cube, each cube has a structure in which spheres are included. If completed, a 3D puzzle will be completed.   Use the same color and number notation for the balls that you put in each cube.
