What Is Sudoku?

Sudoku is a logic-based number puzzle played on a 9×9 grid divided into nine 3×3 blocks. The goal is to fill every row, column, and block with the digits 1 through 9, with no repeats. Despite using numbers, Sudoku requires no math — only logical reasoning and deduction.

Well-constructed Sudoku puzzles have exactly one solution. The number of pre-filled cells determines the difficulty: more given digits means an easier puzzle, fewer means a harder one. A properly made puzzle can always be solved through deduction alone, without guessing.

Sudoku puzzles come in many forms — you can play them online in a browser, print them on paper, solve them in puzzle books, or use a mobile app. VeryFreeSudoku offers all of these for free.

Choose Your Difficulty

Each difficulty level uses different numbers of starting clues and requires different solving techniques. Pick the level that matches your experience:

🟢 Easy 36–45 clues 5–15 min 🔵 Medium 30–35 clues 10–25 min 🟠 Hard 25–29 clues 20–45 min 🔴 Expert 20–24 clues 30–60 min 🟣 Evil <20 clues 45+ min

Easy puzzles are perfect for beginners or a quick relaxing session — solvable by scanning rows, columns, and blocks. Medium occasionally requires pencil marks and is the same difficulty as our Daily Puzzle. Hard puzzles demand intermediate techniques like naked pairs and pointing pairs. Expert and Evil require advanced strategies including X-Wing, Swordfish, and XY-Wing.
