Just happened to come out as 4666 puzzles, did not plan it. I use the program Jigsaws Galore to make my jigsaw puzzles and play them on my PC. There is also a Mac version of it. The price is right for the many hours of fun I've had with the game. There are also a bunch of free puzzles to be had on the site, as well as sets you can buy. I've ran into a bug that now and then it will crash on certain photos, but they do not seem to have anything in common, so I have no idea why. Other then that, I love it and recommend it.
