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.  I’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.  Did I mention it’s FREE!  Click the Android Market link from any Android Tegra devices.
