I have the old Puzzle Master when eGames was RomTech. I've used it for years, but now that I have a Windows 8 computer, it's no longer compatible. I've been trying to download newer versions, but with no luck. I'm not happy about this. It's the best jigsaw program I've come across, and I miss playing it.
I love this program. The only puzzles I don't like are the ones with the palm trees. I have made my own puzzles and would be willing to share them with you.
I've been using it for 7 years, and I'm still crazy about it. It dispenses with all the boring physical tasks, like laying out and sorting of pieces, and the tedious search for the borders. Has TONS of extremely useful (read: great) features! And since you can import any electronic image, from your own photos to images on the net, you have literally and endless supply of puzzles. If you enjoy jigsaw puzzles, this is a must-have!
