Art Puzzle
Art Puzzle is a picture puzzle where the image has been cut into square pieces and scrambled. To restore it, you move the pieces around the grid and rotate each one until every part of the picture is back in its right place.
You can choose how hard you want it to be. The grid comes in four sizes, from 3x3 up to 6x6, so a quick puzzle and a long one are both available. Because pieces can be rotated as well as moved, you need to pay attention to details such as lines, colors and edges. It is a good way to exercise spatial thinking.
