And here is a zip file with everything you need to recreate it on your machine:
Your assignment is to add a 'handle' to the slot machine. When the user clicks on the handle the slots should start spinning. Also, you should add a new sound for when the user wins a game. [Note that the sounds will only work properly on IE, if you are running a different browser the coding will unfortunately have to be different to play sounds.. <sigh>..]
