Understanding Sudoku Difficulty
Generating a Sudoku is more than just placing numbers. The difficulty is determined by the logical techniques required to solve it. Our generator offers several levels:
- Easy: Can be solved using basic techniques like finding singles.
- Medium: May require looking for hidden singles or pairs.
- Hard: Involves more advanced techniques like pointing pairs and box/line intersections.
- Expert: Requires complex strategies and a deep understanding of Sudoku logic.
How Our Generator Works
When you select a difficulty level and click 'Generate,' our algorithm performs two key tasks:
- Creates a Full, Valid Solution: It starts by generating a complete and valid Sudoku grid where all rules are met.
- Removes Numbers Strategically: It then begins to remove numbers one by one, constantly checking if the puzzle still has one, and only one, unique solution. The number of clues removed and their positions determine the final difficulty.
Generating Your Puzzle
Using our tool is simple. Just select your desired difficulty level and click 'Generate Puzzle.' You'll instantly receive a new puzzle and its solution on separate, print-ready pages. This ensures you're never stuck and can always verify your work.
