This website will give you $0.10 to start out with and you can bet on any sport you want. They even have all different types of bets (spread, money line, and over/under bets). The coolest part is, you can look at a little ad that pops up to get a 100% bonus on whatever you win. It's supported by advertising, and naturally the site takes in more of its $0.10 than it gives out (due to odds in the houses favor), so it seems legit.

This will be super kick ass come....oh say one week from today when NFL preseason starts.
