Double click on the same element will cause the border to be removed. To make a swap click on the piece you wish to move. Then click again on the square you want to move it to. Positions of the two pieces will be changed. Continue the process until the image is recovered. The faster you finish the puzzle and the fewer moves you make, the higher your score.
