# Sudoku Rules

The Sudoku puzzle consists of a series of grids. The grids include one large 9 x 9 grid that houses, nine 3 x 3 smaller grids. The purpose of the game is to place a number from 1-9 in each of the grid cells. You don't have to worry about finding the sum of the numbers of the rows, columns, like in Magic Squares.

No addition is involved; however there are three conditions that rely on each other and must be followed. Each number 1-9 can appear only once in each column, once in each row, and once in each small 3 x 3 grid. Mathematically, Sudoku puzzles are a derivation of Latin Squares.
