Section 1: Understanding the Basics
1.1 The Sudoku Grid
At the heart of Sudoku lies a 9×9 grid, divided into nine 3×3 subgrids known as blocks. The grid contains some pre-filled numbers, known as clues, which provide a starting point for solving the puzzle.
1.2 The Rules
The goal of Sudoku is to fill in the empty cells of the grid with numbers from 1 to 9 in such a way that each row, column, and block contains all the numbers from 1 to 9 without repetition.
Section 2: Solving Strategies
2.1 Scanning the Rows, Columns, and Blocks
Begin by scanning each row, column, and block to identify any missing numbers. Look for places where there are only a few possible options for filling in a cell.
2.2 The Process of Elimination
Use the clues in the grid to eliminate numbers that cannot possibly go into a particular cell. For example, if a cell in a row already contains the number 5, then none of the other cells in that row can contain 5.
2.3 Finding Hidden Singles
Examine the rows, columns, and blocks to find cells that can only contain a single possible number. This is known as a "hidden single" and can greatly accelerate your solving.
Section 3: Advanced Techniques
3.1 Pencil Marking
Instead of guessing, use pencil marks to note possible numbers in empty cells. This helps eliminate possibilities and makes it easier to spot patterns.
3.2 X-Wing and Swordfish
These advanced techniques involve finding patterns of numbers that eliminate possibilities in multiple cells simultaneously.
