The web-based games company CleverMedia produced one of the very first (if not the first) web-based jigsaw puzzle game in early 1998. It was created using MacroMedia Shockwave technology and featured a small collection of virtual jigsaw puzzles.
CleverMedia founder, Gary Rosenzweig, created the web-based app and soon started to produce new weekly puzzles using a variety of images. In 2005, the game moved to its current home at JustJigsawPuzzles.com. More puzzle images were added and each day featured a new puzzles. Soon after, the technology was updated to use the more popular Flash browser plug-in.
Gary Rosenzweig still maintains and improves the game, adding more images and features over time. The site is free to play, with no sign-up or membership required.
