I was told about moola.com by one of my school mates. When signing up, you have to supply a U.S. zip code, I believe. Either that or there's some other field that will only accept U.S. addresses. I had to look around on the interzorg to fake a zip code in order to sign up.
The other games on the site are quite fun also, but too based on luck (apart from the RPS one) for my tastes. I proceeded to lose the first four or so pennies I was given, first try.
I also kind of got bored of it, because I could see that there was little chance of me ever reaching the 10 mill, or even anything close to it. It was also doubtful that I'd be able to claim the cash anyway.
If anyone gets further up the ladder than I did, I'd like to know if the standard of competitors increases dramatically or not.
Also, custardchuk, how's this for a signature? It's a placeholder until I create a better one. Enjoy. Hopefully it isn't too pedophile bait-ey for you.
