What is Sudoku?
Sudoku is a number-placement puzzle that originated in Japan but has since become a global phenomenon. The name “Sudoku” is short for the Japanese phrase “Sūji wa dokushin ni kagiru,” which means “the digits are limited to one occurrence.”
The traditional Sudoku grid consists of 9×9 squares, divided into nine smaller 3×3 grids. The objective is to fill in the blank cells so that each row, column, and 3×3 grid contains all numbers from 1 to 9 without repetition.
Sudoku isn’t just a pastime; it’s a brain exercise that sharpens logical reasoning and problem-solving skills.
How Do You Play Sudoku?
The Rules of Sudoku
- Grid Layout: A standard Sudoku puzzle has a 9×9 grid divided into nine 3×3 subgrids.
- Objective: Fill in the blanks so that each row, column, and subgrid includes the numbers 1 through 9 exactly once.
- No Guesswork: Sudoku is a logic-based puzzle. Players should not rely on guessing but use deduction to find solutions.
Step-by-Step Guide
- Start with Easy Numbers: Begin by identifying rows, columns, or grids where most numbers are already filled.
- Cross-Check Rows and Columns: For each blank cell, determine which numbers are missing by checking its row, column, and subgrid.
- Use the Process of Elimination: Rule out numbers that already exist in the corresponding row, column, or subgrid.
- Progress Strategically: As you fill in more numbers, new opportunities for deduction will emerge.
