How to Play Sudoku
Sudoku is a number puzzle game played on a 9x9 grid divided into nine 3x3 boxes. The goal is to fill the grid so that each row, each column, and each 3x3 box contains all digits from 1 to 9 exactly once.
The game starts with some cells already filled with numbers. These are called "given" cells and cannot be changed. You must fill in the remaining empty cells using logic and deduction.
Choose between Easy and Medium difficulty levels. Easy puzzles have more given numbers, making them simpler to solve, while Medium puzzles have fewer given numbers and require more advanced solving techniques.
Sudoku helps improve logical thinking, pattern recognition, and problem-solving skills. It's an excellent mental exercise that can improve concentration and cognitive function. The game validates your solution as you play, highlighting any conflicts.
