Instructions

🎮 How to Play

Welcome to Sudoku Levels! The goal is to fill the 9x9 grid with numbers so that each row, each column, and each of the nine 3x3 boxes contains all digits from 1 to 9. Start by analyzing the puzzle and looking for obvious numbers. Use logic to deduce which number fits in each empty cell. A number can only appear once per row, column, and box. If you get stuck, use notes or hints to help you progress through the puzzle and sharpen your logical thinking skills.

🎯 Objectives

Your primary objective is to correctly complete the entire Sudoku grid without any number repetitions in rows, columns, or 3x3 boxes. The short-term goal is to solve each individual puzzle you start. For long-term success, aim to progress through increasingly difficult levels, from Easy to Expert, building your logical deduction skills. Victory is achieved by filling the last empty cell with the correct number, completing the puzzle error-free.

💡 Pro Tips

🎪 Master advanced techniques like "pencil marking" (noting candidates) to spot hidden singles and naked pairs, which are crucial for harder puzzles.
⚡ Focus on a single row, column, or box at a time to avoid feeling overwhelmed. This improves your scanning efficiency and speed.
💰 While hints are useful, try to minimize their use to truly train your brain and achieve a greater sense of accomplishment.
🏆 To unlock achievements and climb the leaderboards, consistently complete puzzles. Speed comes with practice, so focus on accuracy first to build a strong foundation.
