If you're using a phone or tablet with a Tegra chip inside it, you'll want to check out Zen Pinball THD, which hit the Android Market today. It's a great game, using advanced physics for ball movement, has great tables included -- Marvel's Fantastic Four table is really, really, cool -- and includes multiplayer mode. All for free. To top it off, it's even OpenFeint-enabled for those who like a bit of competition in their mobile gaming. We've been fooling with the press demos, and it's a very well done piece of work. Gameplay is fast, realistic, and beautiful. Any pinball fan or mobile gamer should enjoy this one, and with the free price tag there's no reason not to try it. Hit the break for the download link and the gameplay trailer.
