When you click on the "Compose puzzles" button (or click directly on the picture), a window will open where you can then enter your (alias) name. After entering your name, the puzzle should appear. Be patient - this may take a few moments. The picture is divided into rectangles and scrambled in a random sequence. To switch the places of two puzzle pieces, first click on one of the pieces and then click on the second piece. The challenge is to compose the jigsaw puzzle quickly using the least amount of moves.
