So what is Sudoku exactly?
Sudoku is a puzzle game designed for a single player, much like a crossword puzzle. The puzzle itself is nothing more than a grid of little boxes called "cells". They are stacked nine high and nine wide, making 81 cells total. The puzzle comes with some of the cells (usually less than half of them) already filled in, like this:
Each little square is called a "cell." Most often, Sudoku cells are filled with numbers (1-2-3-4-5-6-7-8-9), but sometimes pictures or Japanese symbols are used instead.
