Rules:

Each row must contain all digits from 1 to 9 without repetition.

Each column must contain all digits from 1 to 9 without repetition.

Each 3×3 subgrid must also contain every digit from 1 to 9 exactly once.

Gameplay:

The puzzle starts with some cells pre-filled (called "givens").

Using logic and elimination, players deduce the correct numbers for empty cells.

No guessing is required—only deduction!

Origins:

Modern Sudoku was popularized in Japan in the 1980s (the name "Sudoku" means "single number" in Japanese).

Its roots trace back to 18th-century Swiss mathematician Leonhard Euler's "Latin Squares."

Appeal:

Sudoku enhances logical thinking, concentration, and pattern recognition.

It has multiple difficulty levels, from beginner to expert.
