If you've ever glanced at a Sudoku puzzle and felt overwhelmed by the grid of numbers, you're not alone. But don't worry—this classic puzzle game is easier to understand than you might think.

What is Sudoku?

Sudoku is a logic-based number puzzle that has become one of the most popular games around the world. The goal is to fill a 9x9 grid so that every row, column, and 3x3 subgrid (also called boxes or regions) contains all the digits from 1 to 9 without repeating any numbers.

Basic Rules

Each number from 1 to 9 must appear exactly once in each row.
Each number from 1 to 9 must appear exactly once in each column.
Each number from 1 to 9 must appear exactly once in each 3x3 box.

That’s it! No math required—just logic and a bit of patience.

Types of Sudoku Puzzles

While the traditional 9x9 puzzle is the most common, there are many exciting variations:

Mini Sudoku: Uses a 4x4 or 6x6 grid—perfect for beginners.
Samurai Sudoku: Multiple overlapping Sudoku grids combined into one.
Killer Sudoku: Combines elements of Sudoku and math, using cages with sum clues.
Diagonal Sudoku: Digits must also be unique along both main diagonals.
