I've tried a few other jigsaw games and been disappointed each time. The good reviews made me decide to get this one. So glad I got it. It's by far the best. There are dozens and dozens of puzzles and the pictures are beautiful and varied. You can look at a preview of the puzzle at any time if you feel like you're losing sight of the "big picture." You can also have a ghost picture which can help if you're stuck while searching for the next piece of set of pieces. There's also a hint function, but I haven't used that. You can choose the number of puzzle pieces, although if you do anywhere near the max, the pieces are very tiny which forces you to use the zoom function constantly. That is the only negative I found to this game. A few other reviewers mentioned that there is no save function, but there is one. When you click the X at the top right corner, your progress is saved. When you come back, you hover over the small photo of your puzzle in the bottom left corner of the front page and click on "continue." I
This game gives you hours and hours of jigsaw puzzle fun. I can't think of a better jigsaw puzzle game to own. It's as close as anything I've seen to a physical jigsaw puzzle.
