What is the Sudoku Generator?

The Sudoku Generator is a free online tool that instantly creates Sudoku puzzles for you to print. Whether you're a beginner or a pro, you can generate custom puzzles that suit your skill level. Each puzzle also includes a complete answer key to help you check your solutions or learn as you go.

How Does It Work?

Using the Sudoku Generator is simple:

• Choose the Number of Puzzles
  Select how many Sudoku puzzles you'd like to generate in one go (between 1 and 50).
• Select Difficulty Level
  Pick from various difficulty levels (Beginner, Easy, Medium, Hard, Expert). The difficulty setting controls how many numbers are pre-filled in the grid—the harder the puzzle, the fewer the starting numbers.
• Generate & Download
  Click the generate button to instantly create your puzzles. You’ll receive both the puzzles and their corresponding answer keys for easy reference.
