Security roulette

I had some spare time, so I created a little game. I've called it security roulette. The object is to find as many web application security flaws as you can in a given number of websites in a limited timeframe.The number of websites is determined by google and the time limit is self imposed or agreed to if you are challenging someone.

I wrote a quick mashup to help you play. The scorecard could probably use some tweaking. My suggested house rule is "no browser plugins or third party applications allowed".
