Easy Sudoku Online
Play a free beginner-friendly 9x9 Sudoku puzzle. Use notes, hints, undo, and auto-save, then start another puzzle when you finish.
Select an empty cell, then enter a number.
Start With Rows and Columns That Have More Clues
Easy Sudoku puzzles include more given numbers, so a row or column with only two or three empty cells can narrow the candidates quickly.
Confirm Single Candidates First
If a cell has only one possible digit after checking its row, column, and 3x3 box, fill it in before moving to harder patterns.
Scan Each 3x3 Box Slowly
When rows and columns stop giving clues, check whether a digit has only one possible position inside a 3x3 box.
Use Notes Only Where They Help
Filling every empty cell with notes can make an easy puzzle harder to read. Add notes to cells that are narrowed to two or three candidates.
Common Beginner Mistakes
Most wrong entries happen when only the row is checked. Before placing a digit, confirm the row, column, and box together. You can review the basics in the Sudoku rules.
Easy Sudoku FAQ
Where should I start an easy Sudoku puzzle?
Start with the row, column, or 3x3 box that has the fewest empty cells. Single candidates are easier to spot there.
Should I write many notes?
For easy puzzles, use notes sparingly. Too many candidates can hide cells that are already solvable.
Is it okay to use hints?
Yes. After using a hint, check why that digit works by looking at the row, column, and box.
