On this page I have collected links to all the JavaScript puzzle simulations on my site, together with easy links to call up the webpage about the puzzle, and the source code so that you can see how they work.
The scripts that use 'layers' are marked with an asterisk. These do not work on older browsers, as you need at least Internet Explorer 5, Netscape 4, or equivalent. All the scripts have only been tested with IE5, and Mozilla or Firefox, so please let me know if any of them do not work for your browser.
