Sudoku is a logical number puzzle puzzle game that is not only very interesting, but also very good for our brains. Adults often play Sudoku to keep their brains young. Children often play Sudoku, which can exercise their brains and improve their ability to think logically.
Elderly people often play Sudoku, which can put the brain in a state of excitement, which is beneficial to the health of the body. Sudoku (Sudoku in Japanese) was introduced to Japan by the McKee Kaji in front of you. The mustache is 52 years old and the president of Nikoli, the Japanese authority on digital-filled game publishing.
I don't know if it's to be on par with Walter Mackey, so the English name is also called McKee. Sudoku is a Japanese kanji that he coined, and the game is summed up in two kanji, and the original Japanese meaning of Sudoku is that every number is celibate (su means number, doku means celibacy). McKee majored in literature from college, and after graduating from college, he worked in a printing shop when a friend brought back a digital filling magazine from the United States, which published the year McKee and two friends co-founded Nikoli, which specializes in publishing digital filling games, when he was only 29 years old.
Nikoli is not located in a commercial center, nor in Kanda, where the publishing house is concentrated, but in Tokyo. For more than 20 years, he has been publishing digital games, including quarterly magazines and books, and has also provided hand-designed sudoku to newspapers. A simple numbers game turned into big business in McKee's hands, but his longtime friend and colleague, Mr. Jimmy Goto, said that McKee was rarely seen in the office:
He's a romantic! 」。When it comes to the secret of the company's success, he believes that the most important people are, and what other assets are not important:
We value team spirit and our colleagues are very close-knit and like family.
The special feature of Nikoli's Sudoku is that all the topics are designed by the author himself, not set by a computer, and the difficulties of the participants are already thought out in advance, so it is human to play and not too tricky and discouraging.
The Sudoku craze has swept the world, and mainstream newspapers in Australia, Belgium, France, Spain, Italy, Malaysia, India, Taiwan and other places have appeared**.

Sudoku (Japanese: Sudoku, sūdoku) is a mathematical puzzle game that originated in Switzerland at the end of the 18th century and was invented by the famous mathematician Euler, and later developed in the United States and developed in Japan. The puzzle is a square shape of a nine-square grid (i.e., 3 squares wide and 3 blocks high), and each grid is subdivided into a nine-square grid.
In each small nine-square grid, fill in the numbers from 1 to 9 respectively, so that the numbers in each column and row of the entire large nine-square grid are not repeated.
Sudoku's departure from Japan to become a popular game in Britain today originated from Wayne Gould, a former judge of the High Court of Hong Kong. In 2004, while traveling in Japan, he discovered the magazine's game and brought it back to London to pitch it to The Times and was accepted. The British "Daily Mail" also started three days later**, making Sudoku officially a craze in the UK.
Other countries and regions have also begun to ** Sudoku due to its influence. At this point, the wind of Sudoku quickly blew all over the world, and its popularity was no less than Apple's iPod

Players need to deduce the hidden numbers of the remaining spaces of all the stove socks according to the known numbers on the 9 9 board, and meet the requirements of each row, each column, and each thick line (3*3) The numbers in the palace contain 1-9 and do not repeat.
The Sudoku board is a nine-house board, and each house is divided into nine sub-squares. In these 81 grids, certain known numbers and solution conditions are given, and the numbers from 1 to 9 are filled in the other spaces using logic and reasoning. Each number from 1 to 9 appears only once in each row, column and house, so it is also called "nine-square grid."

This is window Sudoku, but the rules are not strictly described, so it is misleading.
Window Sudoku includes "Sudoku with a 9-square window to a shirt Sudoku" and "Sudoku without a 9-square window".
