Master Every Level: From Basic to Expert Difficulty

Sudoku Vault believes that every player deserves a challenge that feels just right. That's why we meticulously craft each grid across four distinct difficulty levels, ensuring that your experience is always engaging, never frustratingly impossible, and continually stimulating. Progress through these levels as your skills grow, always finding a fresh mountain to climb.

• Basic: Perfect for new players or those seeking a gentle brain tease. These puzzles provide plenty of starting numbers, allowing for straightforward deductions and helping you grasp the core mechanics. It's the ideal entry point into our free to play logic game.
• Normal: A balanced challenge for players who have a solid understanding of Sudoku rules. Normal grids require more thoughtful deductions and introduce situations where simple scanning isn't always enough, pushing you to refine your strategies.
• Hard: For experienced Sudoku solvers looking to test their limits. Hard puzzles feature fewer initial numbers, demanding more complex logical steps, pattern recognition, and often, multi-step deduction to solve. This is where your true puzzle skill is put to the test.
• Expert: The ultimate test of your Sudoku prowess. Expert grids are designed to challenge even the most seasoned players, featuring minimal starting clues and requiring sophisticated techniques like X-Wing, Swordfish, or even more advanced strategies.
