Pool Break is pretty good. It has a bunch of different games in it and the ability to play people online. It has a demo version to test out too. Just search it on the market. :thumbup:
Pool Break Pro was the Amazon App Store (Android Market) Free App of the Day a few weeks back. I grabbed it then. If you have and Android phone, the Amazon AppStore is something you'll want to add and check daily. Each day, one app that is normally a "paid" app is free. They have worked out some kind of payment arrangement with the developers who agree to have their app listed as app of the day, so it's good for all. Check it out...
