Getting Started: The Basics of Sudoku
For newcomers, Sudoku is a 9Ă9 grid divided into nine 3Ă3 subâgrids. The objective: fill each row, column, and subâgrid with digits 1â9 without repetition. Start with easy puzzles to grasp the logic, then gradually increase difficulty.
Advanced Solving Techniques
To consistently solve harder puzzles, you need more than just basic elimination. Here are key strategies used by experts:
Hidden Singles & Naked Pairs
The foundation of Sudoku logic. A hidden single is a digit that can only go in one cell within a row, column, or box.
XâWing Technique
An intermediate strategy where a digit is confined to two rows and two columns, allowing elimination of candidates elsewhere. Learn more in our dedicated guide on Sudoku X Wing.
Swordfish & Jellyfish
Extensions of XâWing for three or four rows/columns. These patterns are rare but powerful for extreme puzzles.
The "Sudoku Sleuth" Approach
Methodical deduction that mimics detective work. Develop your sleuthing skills with our Sudoku Sleuth tutorial.
