Description

Two special-shaped magic cubes capable of completing restoration of standard third-order magic cubes in two steps Technical Field The invention discloses two special-shaped magic cubes capable of completing restoration of a standard three-order magic cube in two steps, and belongs to the technical field of magic cubes. Background The traditional standard third-order magic cube is a cube consisting of 26 cubes and a three-dimensional cross connecting shaft. Each face of the cube is provided with 9 small cubes which are divided into corner cubes, side cubes and neutral cubes according to the positions of the small cubes, wherein the corner cubes are positioned on 8 corners, the side cubes are positioned in the middle of 12 sides, and the neutral cubes are positioned in the centers of 6 faces. The corner cubes have 3 faces visible, the side cubes have 2 faces visible, the neutral cubes have 1 face visible, and a total of 54 faces visible. The standard three-order magic cube layer first recovery method, namely seven-step recovery method, is the most popular magic cube method which is most suitable for beginners in the world. The method regards the restoration of a standard third-order magic cube as the construction of a three-layer building. Firstly, foundation is beaten, the restoration of the bottom layer is completed, then, an intermediate floor is established, the restoration of the second middle layer is completed, and finally, the top is sealed and perfected, and the restoration of the top layer is completed. It breaks down a complex problem into seven simple steps, and only needs to memorize a few simple formulas to recover successfully. The layer-first restoration method can complete restoration of the standard third-order magic cube, and the trampling structured thinking is stacked step-by-step fixed achievements. However, the method does not start from the angle of the integral three-dimensional space of the standard three-dimensional magic cube, and finally completes the restoration of the standard three-dimensional magic cube through the cross-type step-by-step fixed achievement. The standard three-order magic cube is provided with nine rotating surfaces in a three-dimensional space, each rotating surface can rotate freely, and the position of the small cube on the cube is changed. In the standard third-order magic cube restoration process, the restoration of the standard third-order magic cube can be realized through a method of reducing the difficulty of a rotating surface step by step and through a cross-type step fixing result, and the method can embody the stereoscopic space imagination of the restoration of the standard third-order magic cube. Disclosure of Invention In order to realize the restoration method for reducing the difficulty of the rotating surface step by step, the problem of restoration of the standard third-order magic cube is solved in a cross type step-by-step fixed achievement mode, and the technical scheme of the invention is provided for improving the imagination of the three-dimensional space of the restoration of the standard third-order magic cube. The invention aims to provide two special-shaped magic cubes capable of completing restoration of a standard third-order magic cube in two steps, which consists of two special-shaped magic cubes, wherein one special-shaped magic cube is a special-shaped magic cube with a 'missing edge centering restoration angle block', the other special-shaped magic cube is a special-shaped magic cube with a 'missing angle centering restoration angle block', and restoration of the special-shaped magic cube in the 'missing angle centering restoration angle block' is completed on the basis of the restoration of the special-shaped magic cube with the missing angle centering restoration angle block, so that restoration of the standard third-order magic cube can be completed smoothly. The special-shaped magic cube comprises a special-shaped magic cube, a standard three-order magic cube, a limit-missing centering restoration corner block and a restoration requirement, wherein the special-shaped magic cube is characterized in that a limit missing is the surface characteristic of the special-shaped magic cube, namely, a limit cube block of the standard three-order magic cube is not present outside the special-shaped magic cube, but the internal structure of the special-shaped magic cube is the same as that of the standard three-order magic cube, which has a supporting function and a rotating function, the centering is a reference object for restoration of the special-shaped magic cube, namely, the absolute position and the relative position of six neutral cubes in the special-shaped magic cube cannot be changed, and the number, the color or the mark on the surface of the special-shaped magic cube cannot be changed, and the restoration requirement is a specific requirement for whether the number, the color or the mark on the surfaces of eight corner c
