Instructions for Solving Sudoku
Sudoku is a puzzle game that involves filling in grids with single digit numbers. Each puzzle has 81 cells in a 9-by-9 grid. Each row, column and individual 3-by-3 grid (located within the overall 9-by-9 grid) must have the numbers 1 through 9 appear in them, with no repeating digits. Although it can seem like a somewhat daunting task at first glance, you may find it enjoyable, or even addicting, after you learn how to play.

Examine each row to start getting ideas for where numbers will go. Each row has nine cells, and each cell will house a number, 1 through 9. However, an entire row must have the numbers 1 through 9 appear in it only once. Find a row with a lot of numbers already filled in, so that the process of elimination is easier. Fill in as many numbers as possible by using logic and deduction.
