This works best for the larger puzzles its a little faster for those who aren't very good at them. You have to stack all the puzzle pieces ontop of each other. (its doesnt matter where.) It doesnt have to be neat but if its really messy won't be as accurate. Than click save than close the window. Than go back to games and puzzles. Open up your saved puzzle and when you see your stack it will be in order so all you have to do is place the pieces where they need to be since there already in order.
