Sudoku is a logic game with numbers that was invented in 1979 by the Japanese mathematician Hiroshi Sudo. The goal of the game is to fill a grid of nine squares with numbers from 1 to 9 so that each number appears only once in each row, column and 3×3 block.

The history of the Sudoku game

Sudoku was invented by Hiroshi Sudo in the 1970s when he worked for a computer game development company. He came up with this game to help his colleagues improve their logical problem solving skills. The game quickly became popular all over the world and was published in various magazines and newspapers.

The popularity of the Sudoku game in Japan has led to its becoming a national treasure. In 2007, the Japanese government declared Sudoku a national game and designated it a national symbol. Since then, the game has become even more popular all over the world.

The rules of the Sudoku game

The Sudoku game is a grid of 9 squares divided into 9 blocks of 3 squares. Each block contains numbers from 1 to 9, arranged in random order. The player must fill the grid with numbers so that each number appears only once in a row, column, or 3×3 block.

Solving a Sudoku game can be difficult, but there are several strategies that can help with the solution. For example, you can start by filling in 3×3 blocks, then move on to filling in rows and columns, and finally fill in the remaining cells. You can also use hints, such as finding numbers in neighboring cells or using patterns in the grid.

There are different levels of difficulty of the Sudoku game, ranging from simple, where all the numbers are in one block, to complex, where all the numbers are scattered throughout the grid. Some players prefer to play more difficult levels to test their skills and improve their strategy.
