The real name of nine-square grid mathematics: Sudoku
The nine-square grid is a logical number game that originated in Switzerland at the end of the 18th century and emerged in the 1st century, originally called "Su Doku", and later simplified to "Sudoku". The rules are simple: fill in the 9x9 squares with numbers 1 to 9, each number appearing only once in each row, column, and 3x3 house (also called a small square). Despite its simple rules, it requires a high level of concentration and logical analysis skills. Whether you are an elderly or a young person, or in your free time or in your busy time, you can relax and exercise your mind by completing a Sudoku.
Tips and strategies
Sudoku is not just a game of trial and error, it has many effective problem-solving strategies:
1. The only candidate method
When encountering rows, columns, or palaces with only one or two empty spaces, analyze possible numbers to fill in.
2. Puzzle finding method
Use the numbers that are already in the row, column or uterus to analyze the number combinations that appear one by one in possible situations to solve the problem.
3. Drop angle method/right angle method
Considering the start and end points of the digital chain in specific situations makes it easier to infer the outcome.
