Choose a puzzle, and once the puzzle is loaded, simply move the pieces around using your mouse to complete your jigsaw puzzle! A small hint is given on each one to help younger kids solve the puzzle.
In the unlikely event that you get a java pop-up that says "Your security settings have blocked an untrusted application from running" just click on your control panel, then the Java icon and on the security settings tab change the setting to "medium". You may need to restart your browser afterward so see the puzzles.
