What Is Sudoku?
Sudoku is a logic-based number placement puzzle that uses a 9×9 grid divided into nine 3×3 boxes. Some numbers are filled in at the start, and the rest must be completed using logic. The puzzle always has a solution that does not require guessing.
Although Sudoku became widely popular in the early 2000s, similar number-placement puzzles existed decades earlier. Its modern form gained traction because it’s easy to learn, challenging to master, and satisfying to solve.
Understanding the Sudoku Grid
The Sudoku grid consists of nine rows, nine columns, and nine 3×3 boxes. Each section must contain the numbers 1 through 9 exactly once.
The Goal of Sudoku
Your objective is to complete the grid so that every row, column, and box contains each number from 1 to 9 without repetition. No math is involved—just logical deduction.
Basic Rules of Sudoku
- Each row must contain the numbers 1–9 exactly once.
- Each column must contain the numbers 1–9 exactly once.
- Each 3×3 box must contain the numbers 1–9 exactly once.
These simple rules apply to every Sudoku puzzle, regardless of difficulty.
How to Start a Sudoku Puzzle
When starting a puzzle, scan the grid for rows, columns, or boxes that already contain many numbers. These areas usually offer the easiest placements.
Beginners should resist the urge to guess. Every correct move can be deduced logically by eliminating impossible numbers.
Essential Sudoku Techniques for Beginners
These core techniques are enough to solve most easy and medium puzzles.
Naked Singles
If only one number can fit in a cell based on existing numbers, that cell must contain that number.
Hidden Singles
A number may only fit in one position within a row, column, or box—even if that cell still has multiple candidates.
Pencil Marking
Writing small candidate numbers in empty cells helps track possibilities and eliminate options logically.
Intermediate and Advanced Sudoku Tips
Harder puzzles require more careful observation and pattern awareness.
Scanning and Cross-Hatching
Scanning rows and columns helps eliminate candidates. Cross-hatching focuses on interactions between rows, columns, and boxes.
Pattern Recognition
As you gain experience, you’ll begin to recognize common patterns that reveal placements without checking every cell individually.
Common Mistakes New Players Make
- Guessing instead of using logic
- Ignoring obvious placements
- Spending too long in one area
- Forgetting to re-check rows and columns
