A great, simple android version of the classic Risk game. You can play against up to 6 players computer or human. In the free version you're passing the phone back and forth, but it's still fun. My 11 year old daughter, who's never played Risk (I know, I've failed as a parent) loves this game too.

There's a Skynet option, which makes the computer more likely to attack humans. I've not tried it on that mode yet. I don't want my phone learning how I attack...
