Sudoku Basic Rules


Before starting to play Sudoku, let's explain the three basic rules of Sudoku:

  • The numbers in the small nine-square grid are not repeated
  • The numbers in the horizontal row of the big Jiugong grid are not repeated
  • The vertical numbers in the big Jiugong grid are not repeated
When starting to solve the puzzle, you can first look up the number of hints that have been given, and start filling in the corresponding grid according to their position and number. Using the known number of hints, observe the blank cells in each row, each column and each small square, and infer the number that should be filled in according to the rule of non-repetition. 


💡The Sudoku difficulty of the demonstration questions is "easy", which is suitable for beginners to practice!




At the beginning, first observe the existing number distribution " in the "Big Nine Palaces" grid. In the rules of Sudoku, each horizontal column, column and small nine-square grid are non-repeating numbers from 1 to 9 , so we should not narrow our eyes to the small nine-square grid, as it is easy to make mistakes in judgment .

We can first exclude the existing numbers and find possible candidates. Taking the red box in this picture as an example, the numbers that have not yet been filled in are "2" and "3".



According to the rules of the Sudoku game, as long as there are already numbers in the horizontal and vertical rows, they will not appear again. From this we can see that the number in the blue box can only be "2".



At present, we have determined the correct positions of the numbers "2" and "3", and solved other numbers with the same logic.




Next, let’s look at the vertical row, and first exclude the existing numbers. The numbers that have not yet been filled in are "4" and "9".




According to the game rules of Sudoku: the numbers in the small nine-square grid are not repeated (the yellow area already has 9), we can determine the correct positions of the numbers "4" and "9".




Let's take a look at the small nine-square grid in the red area. There are still two spaces left for numbers. 
Excluding existing numbers, the numbers that have not yet been filled in are "4" and "6".



According to the rules of the Sudoku game, as long as there are already numbers in the horizontal and vertical rows, they will not appear again. There are already 6 in the yellow area, so we can see that the number can only be "4" .




Follow the above logic to solve the puzzle easily! What is the last number left?


That's right...the answer is "7"!




Summarize


The number and difficulty of Sudoku puzzles are very rich, and readers can choose puzzles of different difficulty to challenge according to their own abilities . And the specific solution to each puzzle is unique. When solving puzzles, you need to think flexibly, continue to try and deduce, which is very beneficial for cultivating and exercising the brain's ability, and you can get a sense of accomplishment from the process of solving puzzles!

If you want to train your brain by solving puzzles through games, Sudoku is definitely a very suitable choice. It's convenient, fun, and endlessly challenging and intellectually exercising. Come and try the fun of solving puzzles!
