Pinball

Monster Pinball is a gorgeous and fantastically executed game for the iPhone. I would even go so far as to say it's possibly the best pinball app out there to date! Matmi sure hit the nail on the head with this one. The controls are fantastic, the animations are smooth as butter, and the overall look is polished and not quite like anything I've ever seen before.
When you open the game you're given 3 options; Play, Help, and Scores. Play will obviously start up a new game, but you may want to look at the controls first. Sure, they're completely natural feeling, but the Help screen is kinda cool and worth taking a look at. Everything feels very intuitive. Pull back on the spring mechanism by sliding your finger downwards and releasing to set the ball into motion. Then, using your thumbs, simply tap the coordinating buttons at the bottom of the screen to activate the levers. These buttons are small enough that it gives the "table" a very wide open feel, but big enough to be able to access easily in most situations. I say "most" because people who have a heavy duty iPhone case with a high rim may find it somewhat awkward to reach the buttons.

Built up on a realistic 3D engine, The Deep is a pinball game that immerses you in a fantasy treasure hunt. You are sailing the most perfect submarine in the world which will be your reliable guide in the mysterious world of ocean depths. Sunken ships and ruin tunnels, underwater hunting and chests full of treasures are waiting for you. Your assistant / on-board computer will provide you with all information necessary for successful passing of secret missions.
