To do Sudoku, follow these basic steps and rules:
Sudoku Rules
- The Sudoku grid is a 9x9 square divided into nine 3x3 sub-grids (boxes).
- Fill the grid with numbers 1 through 9.
- Each row, each column, and each 3x3 box must contain all numbers from 1 to 9 without any repetition
How to Play Sudoku
- Start with the given numbers: The puzzle begins with some cells already filled in. Use these as clues
- Use logic, not guessing: Sudoku is a logic puzzle. Never guess; instead, use deductive reasoning to figure out where numbers go
- Process of elimination: For each empty cell, determine which numbers are possible by checking the row, column, and box it belongs to. Eliminate numbers already present in these areas
- Look for singles:
- Naked singles: If a cell can only be one number based on elimination, fill it in.
- Hidden singles: If a number can only go in one cell within a row, column, or box, place it there
- Scan rows, columns, and boxes: Look for numbers that are missing in a row, column, or box and figure out where they must fit by checking other areas of the grid
- Use pencil marks: Write down possible candidates for each empty cell in small numbers. Update these as you fill in more cells
- Repeat and refine: Continue scanning, eliminating, and filling in numbers until the puzzle is complete
Tips for Beginners
- Start with easier puzzles that have more numbers filled in.
- Focus on one number or one box at a time.
- Be patient and methodical; Sudoku rewards logical thinking and pattern recognition
By following these rules and strategies, you can solve Sudoku puzzles effectively without guessing
