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.

Congratulations!! You have solved the 15 puzzle! If you are playing a version on the computer it will usually fill in the 16th square when you win so you can see the whole thing completed. If you get to the end and things aren't working, look back and double check all the numbers to make sure that they are all in the correct place. If you accidentally put a number in the wrong place on the top two rows it will be impossible to get the numbers into the correct spot at the end.
