Rated Sudoku Premium Sudoku Experience
Complete Sudoku experience for everyone.
Play - Efficient Input System
Tired of slow manual input of candidates and making mistakes? Our unique cell+skill input system revolutionizes the way you play Sudoku. Simply spot a pattern like an X-Wing, select a relevant cell, click the "Fish" skill, and watch the eliminations happen automatically. No more manual candidate management or fear of errors—the game handles the work, letting you focus on the fun of solving. If the skill doesn't apply to the cell, nothing will happen, ensuring a completely error-free experience.
Campaign - From Beginner to Expert
Whether you're a complete novice or looking to sharpen your skills, our campaign mode is your path to expertise. We guide you step-by-step from the absolute basics to competition-level strategies. Learn to spot Naked/Hidden Singles, master Hidden and Naked Sets, and conquer complex patterns like X-Wings, XYZ-Wings, and Skyscrapers. With clear, easy-to-understand explanations, clear diagrams, and targeted practice puzzles, you'll understand the "why" and "how" behind every move.
