Your finished puzzle cannot be saved and dream on if you want to sit and admire your accomplishment. There are four pastel background colors and they are pretty bland with no way to adjust the shades. There are approximately 300 pieces max to each puzzle, so for me there isn't much challenge. Sorting the pieces is a nightmare but there is the option of working the border separately. The options are basic and a few features are ok, they work fine but offer little to the fun of assembly. Things and people are out of place in an Ice Age puzzle, as well. I'm in total agreement with Pennmom regarding all the staged pictures of misc boring things and uninteresting people. I'm wondering why this dev is in the business of designing puzzles in the first place! The images were not creative, attractive or interesting.
Don't Even Bother! This one is a real stinker! No matter how far beyond desperate I may be for a jigsaw puzzle, I would not even consider this one.
