About Sudoku

Sudoku is a classic logic puzzle game that challenges your reasoning skills and concentration. With simple rules but deep strategic thinking, Sudoku has become one of the most popular brain-training games worldwide. Players must fill a 9x9 grid with numbers from 1 to 9 without repeating any number in the same row, column, or 3x3 box. Whether you play casually to relax or competitively to sharpen your mind, Sudoku delivers the perfect balance of challenge and satisfaction.

Gameplay Overview

In Sudoku, you complete a 9x9 grid by filling in numbers from 1 to 9 without repeating any number in the same row, column, or 3x3 box. Each puzzle starts with pre-filled clues and has only one correct solution.

As difficulty increases, fewer clues are provided, requiring stronger logic and concentration. Use deduction—not guessing—to solve the grid efficiently and improve your completion time.
