Sixteen Puzzle

moves

How to Play: To start, click on the Easy puzzle or Hard puzzle button to mix up the pieces. The aim is to get them back in order by clicking on the yellow arrows to slide the pieces left or right, up or down. The Easy puzzle target is 3 moves, for the Hard puzzle it is 12 moves (or less!). Can it be that simple? The Reset button lets you can try again if a particular puzzle needs more than one go.

This puzzle is less sophisticated but has the same play as a Java applet puzzle called ‘Omnislide’ by Donald Sapello which uses photographs.
