Chemical Jigsaw Puzzle

It is best to move all the pieces out of the rectangular area. If a piece is "fit" over an existing one you will not be able to access the piece below.
Animiated images may not synchronize until the puzzle is completed.
The puzzle can be dragged by grabbing the image. This feature can be turned off with the labeled toggle button. Break the puzzle into as many pieces as you want. Break it again. Move the pieces into position to solve it. Stuck? Use the Hint button. Fed up? Let the puzzle solve itself with the Solve button. Load a new puzzle image and play with that one for a while. The images have not been pre-loaded, so you will have to wait for a download when you switch images. At any stage, an optional grid can be turned on and off to assist in piece placement. If the puzzle has a low piece count, the grid may slow the puzzle down on IE4. In NN4, after a puzzle drag or a new image load, the form buttons may not display properly. Scroll the puzzle off the screen and back on to fix, or in WIN95, select View-Refresh.
