What is Sudoku?
Sudoku is a logic-based number-placement puzzle. The objective is to fill a 9 × 9 grid with digits so that each column, each row, and each of the nine 3 × 3 subgrids that compose the grid (also called “regions”, “blocks”, or “boxes”) contain all of the digits from 1 to 9 without repetition.
The puzzle starts with some cells already filled with numbers, and the challenge is to fill in the rest of the grid using logic and deduction. Sudoku puzzles vary in difficulty, and they have become immensely popular as brain teasers and time-passers.
Steps to Solve Sudoku
Some steps to solve classic sudoku include:
Step 1: Start with the numbers already provided.
Step 2: Scan rows, columns, and blocks for missing numbers.
Step 3: Use elimination to find possible numbers for empty cells.
Step 4: Apply the “Only One Left” rule when only one possibility remains.
Step 5: Look for pairs or triples of numbers to eliminate possibilities.
Note: Practice regularly to improve skills and confidence in solving sudoku.
