Nine-square grid (number game):

Pronunciation: jiǔ gōng gé

Alias: Cosmic Rubik's Cube

Explanation: A number game, originated from Hetu Luoshu, Hetu and Luoshu are two mysterious patterns handed down in ancient China, which have always been considered to be the source of Heluo culture and the source of Chinese civilization, known as the "Cosmic Rubik's Cube". According to legend, in ancient times when Fuxi, the Yellow River in Mengjin County, northeast of Luoyang, emerged from the Yellow River, carrying the "river map" and offering it to Fuxi. Fu Xi evolved into gossip according to this, and later became the source of "Zhou Yi". According to legend, when Dayu, Luoyang Xiluoning County Luohe River surfaced a turtle, carrying the "Luo Shu", dedicated to Dayu. Dayu succeeded in controlling the water according to this, and then drew the world into Kyushu. According to this, the nine chapters of the law were formulated to govern the society, and it was handed down and included in the "Book of Shang", called "Hong Fan". "Yi Ji Ci Shang" says: "The river produces a map, Luo produces a book, and the sage does it", which refers to these two things.

Evolution:

On the river chart, the black and white dots arranged in several arrays contain infinite mysteries, and the patterns on Vena Shu correspond to nine numbers from 1 to 9, and whether it is vertical, horizontal, oblique, or the sum of the three numbers on the three lines, they are all equal

At 15, people did not know at the time that this was the third-order magic square in modern mathematics, and they called this mysterious arrangement of numbers the nine-square diagram. In this regard, Chinese and foreign scholars have made long-term exploration and research, believing that this is the soul of the Chinese ancestors

The crystallization of thinking is the first milestone of ancient Chinese civilization. The two books "Zhou Yi" and "Hong Fan" have an extremely important position in the history of the development of Chinese culture, and are in philosophy, political science, military science, ethics, aesthetics, and literature

The field of learning has had a profound impact. As the source of Chinese history and culture, Hetuluo has made great contributions.

Hetu and Luoshu are the third-order magic squares in mathematics, which are called "vertical and horizontal diagrams" in ancient China. The nine-square grid game is developed on the basis of the vertical and horizontal diagrams. Vertical and horizontal charts were originally used in the daily teaching of ancient mathematicians. Later, it developed into a math word game that everyone loved. After the nine-square grid, a portable skateboarding game was derived - rearrangement of the nine palaces.

Game Description:

Rearranging the nine palaces means "rearranging the nine palaces". This is based on the development of the popular mathematical game at that time - "vertical and horizontal map" (also known as "magic square" or "magic square"). Vena is the most basic 3×3rd order Rubik's Cube, which is the third-order magic square in mathematics. The mathematics books of the Tang and Song dynasties recorded many ways to arrange vertical and horizontal diagrams, and on this basis, the game of rearranging the nine palaces was produced. The earliest form we know of now appears in written records.

In the Tang and Song dynasties of China, it was popular to rearrange the game of nine palaces, on the 3×3 grid board, there are eight numbers from 1 to 8, and the remaining one grid is empty, and the numbers around each space can be moved to space. Start by setting the initial arrangement of numbers, and then start thinking about how to achieve it with the least number of moves.

Gameplay:

There are two ways to rearrange the nine houses:

The first is on a 3×3 grid board, where eight small wooden blocks from 1 to 8 are placed at random, and the number around each space can be moved to the space. Players have to rearrange the small wooden blocks in the order of 12345678, and the one who spells out the result with the fewest moves wins.

The second way to play is the arithmetic game of the nine-square grid, which pushes the arrangement of 8 numbers in the wooden grid, and there are 3 grids in both horizontal and vertical grids, so that the sum of the three numbers on the two diagonals in each row and column is equal to 15. While calculating, we must also think about how to push the number squares to the corresponding positions, this game not only tests people's numerical reasoning ability, but also tests people's thinking and logic ability.

Game Rules:

The rules of the nine-square grid game, 1 to 9 nine numbers, there are 3 squares in both horizontal and vertical directions, think about how to make the sum of the three numbers on the two diagonals in each row and column equal to 15. This game not only tests people's ability to reason about numbers, but also tests people's ability to think logically.

Game Significance:

The nine-square grid game has a great effect on people's thinking exercise, and people have been aware of the educational significance of the nine-square since ancient times. It has had a huge impact for thousands of years, and has appeared in literature, film and television. The nine-square grid was first called "Luoshu", and now it is also called "magic square".

In "The Legend of the Condor Heroes", Huang Rong once cracked the nine-square grid, the formula: wear nine shoes one, three on the left and seven on the right, two or four have shoulders, eight or six are feet, and five are in the center.

There is also a mantra: "One is in the center of the upward line, do not forget to fill in obliquely; put down when the upper frame is out, and put it to the left when the right is out of the frame; fill in the lower grid with the weight of the lower row, and the upper right row is the same." This mantra applies not only to the nine houses, but also to the odd number of the nine houses that are promoted, such as the five-five chart, the seven-seven chart, and so on.
