How does Jiugongge quickly calculate the result?

There are many formulas for calculating Jiugongge. For example:

1, 24 is the shoulder, 68 is the foot, up nine down one, left seven right three.

2. Don't forget to fill in the middle of the ascending line in turn; Put it down when loading and unloading the box, and put it left when unloading the right box; The box below is filled with the weight of this line, and the weight of the upper right line is the same.

This formula is not only applicable to the nine palaces, but also to the extended odd-numbered nine palaces, such as the five-five diagram and the seven-seven diagram.

Game part

There are two ways to play "Rearrange Jiugong":

The first type: on a 3×3 grid, eight small wooden blocks from 1 to 8 are randomly placed, and the numbers around each space can be moved into the space. Players should rearrange the squares in the order of 12345678, and the person who spells the result with the least number of moves wins.

The second way: the game is like the arithmetic game of Jiugongge, which advances the arrangement of eight numbers in the wooden lattice, three squares in two directions, so that the sum of the three numbers on the two diagonal lines of each row and column is equal to 15.

While calculating, we should also think about how to push the number box to the corresponding position. This game not only tests people's numerical reasoning ability, but also tests people's thinking logic ability.
