How do you start playing Sudoku?

Begin by scanning the grid for rows, columns, or boxes with more numbers. Check which digits are already used and remove them from the empty squares. Use small notes to keep track of possible numbers.

Do you need to guess in Sudoku?

No. A valid Sudoku never requires guessing. Every number can be placed through logic by checking rows, columns, and boxes.

What is the easiest method for beginners?

Beginners should look for Naked Singles and Hidden Singles. These are simple placements where one number clearly fits based on elimination.

How can I get better at Sudoku?

Use notes consistently, scan the grid often, and switch areas when stuck. With practice, patterns become easier to notice.

How to Play Sudoku: A Simple Guide for Beginners

Sudoku looks more complicated than it really is. Once you understand where to look and how to narrow down choices, the puzzle becomes clear and enjoyable. This guide gives you the essential steps to start solving right away.

If you want a short explanation of how rows, columns, and boxes work together, you can read our Sudoku rules and basic concepts before practicing below.

What You Need to Know First

Sudoku is a logic puzzle. You fill the empty squares so every row, column, and 3×3 box contains the numbers 1 to 9 without repeats. You do not do math; you simply check what fits and what does not.

Step 1: Read the Grid

Begin by scanning the puzzle:

Rows or columns with more numbers are easier to start with
Boxes with many clues often reveal simple placements
Numbers that appear often on the board tend to block more positions

Your first goal is to understand which areas give you the most information.

Step 2: Remove Impossible Numbers

Pick an empty square and ask three quick questions:

Which numbers already appear in this row?
Which numbers are already in this column?
Which numbers are already in this box?

Any number you see in these places cannot go in that square.
If only one option remains, that is the answer.

Step 3: Use Notes to Track Options

For squares with several possible numbers, write small notes inside the cell. Notes help you notice patterns and prevent you from guessing. When a new number is placed elsewhere, many notes will change or disappear, revealing clear answers.

Step 4: Look for Singles

Two simple ideas help beginners solve most puzzles:

Naked Single

A square has only one possible number left.

Hidden Single

Inside a row, column, or box, a number fits in only one position, even if several notes appear.

These two ideas alone can solve most easy puzzles and many medium ones.

Step 5: Keep Updating the Board

Sudoku progresses step by step. Each number you place:

Reduces options in nearby squares
Makes your notes cleaner
Creates new singles
Opens new chances in other areas

If you get stuck, move to another row, column, or box instead of forcing progress in one place.

Common Mistakes to Avoid

Guessing: A correct puzzle never requires guessing
Skipping notes: Trying to hold all possibilities in your head leads to errors
Staying in one spot too long: If nothing changes, switch to another area
Changing given numbers: Starting numbers are fixed and must stay as they are

The best way to learn is to practice. Begin with an easy puzzle to get used to notes and singles, then move to higher levels when you feel comfortable.

Final Tip

Sudoku is solved through small, clear steps, not sudden big jumps. Stay patient, update your notes often, and check rows, columns, and boxes regularly. Each correct move makes the next one easier.
