Sudoku is a fun and engaging puzzle game that can be enjoyed by people of all ages. If you’re a beginner looking to dive into the world of Sudoku, it’s essential to start with some very easy techniques that will help you get started. This guide will cover several basic strategies to solve Sudoku puzzles quickly and efficiently.
Understanding the Basics
Before delving into techniques, it’s crucial to understand the basic rules of Sudoku. The standard Sudoku grid consists of 9×9 cells divided into nine 3×3 subgrids (also known as regions). The objective is to fill the grid so that each row, column, and region contains the numbers 1 through 9 without repeating any numbers.
Start with the Obvious Numbers
One of the easiest ways to start solving a Sudoku puzzle is by filling in the obvious numbers. Look for cells where only one number can fit based on the existing numbers in the row, column, and region.
Single Possibility Technique
This technique involves scanning each cell to see if there’s only one possible number that can go in that cell. Here’s how you do it:
- Identify a cell.
- Check the related row, column, and region.
- If only one number from 1 to 9 is missing, fill it in.
Use Pencil Marks
Pencil marks are tiny numbers you can write in the corners of cells to keep track of potential candidates for each cell. This technique helps visualize possible solutions and narrows down cell values.
Creating Pencil Marks
Follow these steps to create and use pencil marks effectively:
- Identify empty cells in the grid.
- Write down possible numbers for each cell in small numbers.
- Update pencil marks as you fill in confirmed numbers.
Look for Hidden Singles
A hidden single is when a number can only go in one cell within a row, column, or region, even though other empty cells could potentially hold it. Identifying hidden singles involves more observation but is very effective.
Identifying Hidden Singles
| Step | Description |
|---|---|
| 1 | Select a number (e.g., 5). |
| 2 | Scan each row, column, and region for cells that can’t contain that number. |
| 3 | If one cell is the only place left for that number, fill it in. |
Practice Makes Perfect
The more you practice these basic techniques, the better you’ll become at solving Sudoku puzzles. Start with simpler puzzles designed for beginners and gradually move up to more challenging ones as your skills improve.

To further hone your skills, consider using online resources:
- Sudoku apps that offer different difficulty levels.
- Websites with daily puzzles and solution guides.
- Forums where you can discuss strategies and get tips from experienced players.
By mastering these very easy Sudoku techniques for beginners, you’ll find yourself solving puzzles more quickly and efficiently. Happy puzzling!
