I'm completely addicted to this online basketball game. I played it throughout the Raptors victory this afternoon. If you try it, you'll like it, and you'll keep on trying it.
A big part of the allure is that you compete with several hundred other players throughout the world in real-time. You're essentially representing your country, as it gives you a flag based on your IP address.
My high score is 149 points, but I didn't get a screen cap. Here's my most recent game. I'm definitely getting better, consistently scoring over 100 points and getting every closer to that elusive top ten.
