At the beginning of the game, there are already some preset numbers (called "starting numbers") in the grid, which help you start reasoning. You need to infer which numbers should be filled in other grids based on these numbers.
Your task is to use logical reasoning to fill in all blank grids with numbers from 1 to 9, making sure that there are no repeated numbers in each row, column, and 3x3 square.
Although Sudoku uses numbers, the game does not involve any mathematical operations at all. It tests your logical thinking and observation. You need to eliminate other impossible options based on the existing numbers to get the correct answer.
1.What is the goal of Sudoku?
The goal of Sudoku is to fill in the numbers 1 to 9 in a 9x9 grid, making sure that the numbers in each row, column, and 3x3 square are not repeated.
2. Does Sudoku require math knowledge?
No! Although Sudoku uses the numbers 1 to 9, the game does not involve math operations. Sudoku is a game based entirely on logical reasoning and does not require any math knowledge.
3. How to start playing Sudoku?
At the beginning of the Sudoku game, some numbers have been filled in the grid. Based on these known numbers, you need to use logical reasoning to infer which numbers should be filled in other spaces, making sure that there are no repeated numbers in the rows, columns, and 3x3 squares.
4. What techniques can help me solve Sudoku?
Elimination method: Eliminate impossible options based on known numbers.
Candidate number method: Record the possible numbers in each space and eliminate them step by step.
Regional analysis: Analyze the rows, columns, and 3x3 squares at the same time to determine the location of the numbers.
5. Why do I sometimes feel that Sudoku is unsolvable?
If you get stuck, it may be because of a mistake in reasoning that prevents you from continuing. It is recommended that you check the numbers you have filled in to see if there are any mistakes. Sudoku always has a unique solution, and as long as the logical reasoning is correct, you will eventually solve the puzzle.
6. Is Sudoku good for the brain?
Yes, Sudoku is a very good brain training game. It can improve your logical thinking ability, concentration and problem-solving ability. Regularly playing Sudoku has a long-term positive effect on the brain.
