Here, the left-hand picture has been
cut into 16 squares with the most lower right-hand one removed.
Then the tiles have been randomly shuffled and your task is now to
let them resemble the original picture. To accomplish this, you can move
tiles that are vertically or horizontally aligned with the hole. Movable
tiles will highlight greenish if you move the mouse over them. Simply
click, and all tiles between the highlighted one and the hole will be
moved towards the hole. Each single tile counts as one move then.
The puzzle will always resolve (thanks to Nathan Bullock).
Note: Konqueror is quite slow. Mozilla and Opera work much
