The aim was to write a perfect replica of the Windows game as far as the board itself goes, which I think I've achieved. I also aimed to make the game easily customisable in terms of look and behaviour, so the version you see has a fair amount of presentation code in the page that hooks into events in the main game script. I don't really expect anyone would want to use my code, but it pleases me to know that someone could.
I expected it to be easy to program and by and large it was, though as ever with such projects I learned a few things unexpectedly along the way, which I will document another day.
UPDATE January 2010: I've updated the mouse button detection and it now works properly on WebKit.

- Firefox/Mozilla/Netscape 6+ (earlier versions of Mozilla may have minor layout issues)
