These instructions provide one method for solving the 15 Puzzle. The instructions provided here are meant to be a step by step process outlining one algorithm for solving the 15 Puzzle. These instructions are not meant to be an exhaustive explanation of how to move the tiles around the 15 Puzzle board. If the reader would like to learn more about the mechanics of the 15 Puzzle game, they are encouraged to experiment with the puzzle to learn how the tiles move around. My purpose here is to give instruction on where to put the pieces after you know how to move them around the board.

The 15 Puzzle is a good form of entertainment that has been popular for over 100 years. The puzzle is simple enough that it can be solved by children, but adults can have a difficult time solving it at first if they aren't good at solving puzzles. This set of instructions will be easy, and will only take 1 - 2 minutes for someone who is familiar with how to move the pieces around on a 15 Puzzle board. For beginners, solving the puzzle with these instructions can take 10 minutes or longer. This puzzle is fun, simple, and entertaining. Once you have solved the puzzle you will gain a sense of accomplishment. The skills you gain will help you to be able to solve more difficult puzzles. 

The 15 Puzzle is traditionally made up of the board shown in the picture above. However, sometimes a picture of a bird, a flower, or something else is swapped for the numbers, so instead of putting the numbers in order you try to put the image back together. In this version the numbers start out scrambled, and the goal is to slide the pieces around until you get them in order from 1 to 15 as shown in the picture above. 

All of the pictures in this set of instructions are screenshots of me playing the 15 Puzzle on my computer. The version of the puzzle shown in the pictures comes with Windows 7 in the Desktop Gadgets.

Solving this puzzle is not hazardous in any way that I know of.
