Small update in a Javascript application (1 hour task)

I want to implement a simple JS/HTML/CSS Slot machine on my website. I've got open source code from GitHub that works 95% but it lacks 3 things:

1. Can we rig it so that every 100 tries someone wins, then every 500 tries someone wins, but all the other times there is no winner?

2. Can it auto stop, not manually stop

3. When someone wins, can JS save the winner in a text file or db (communicate with PHP/MySQL basically)

Any JS guru out there to help

Skills: Javascript, PHP, CSS, jQuery / Prototype, MySQL
