When you can see the image on the gamescreen, give time for yourself to memorize the image. When you have fully familiarized the image, you can now press the "shuffle" button located at the lower right corner of the gamescreen. The pieces will now be mixed from each other and all you have to do is to put them back together to form the image that you have familiarized. You will be given quite a long time limit. You can see the amount of time that you have on the lower part of the gamescreen. Just use the mouse to place the pieces on their proper location.
Mouse only.
