International digital chess is a new mathematical puzzle game, whose goal is to cultivate and improve people's sensitivity to numbers and mathematical thinking ability. The game was developed and popularized by six members of the International Digital Council at the end of the 20th century, and now it has become popular all over the world.

The chessboard of chess is a grid of 10x 10, which consists of 100 squares. You can put a number in each box, ranging from 1 to 100. Before the game starts, players need to put all the numbers on the reverse side to increase the randomness and difficulty of the game.

The goal of the game is to reach or exceed the target number of 6 1 by using basic mathematical operations such as addition, subtraction, multiplication and division. For example, if the number on the square is 7, the player can use addition to make the number on the square 14(7+7) or use multiplication to make it 49(7x7). During the game, players can move their own pieces vertically and horizontally.

In addition to ordinary chess pieces, there is also an "emperor" chess piece in international digital chess, whose role is to control the whole chess game. If one or both emperors can reach or exceed the target number of 6 1, then the player can win.

The rules of chess are easy to understand and suitable for people of different ages. By using mathematical operations and strategic planning, players can exercise their thinking ability, reaction ability and teamwork ability in the game. In addition, chess is also very interesting and entertaining, which can enhance people's friendship and communication.

Generally speaking, chess is a very interesting math puzzle game, which can not only help people improve their math skills, but also enhance their thinking ability and creativity.
