Toy Box is a hidden gem on the app store. Not many people know about it, but it is by far the best physics game (at least in my opinion). You can make shapes and add motors, axels, springs, rope, balloons etc to make things such as cars, rag dolls, catapults etc. I even made a fully automatic rifle by copying the real mechanism with the firing pin. It's a great app, by far the best physics app that I have tried.
A few others I enjoy... The Little Tank That Could Melon Golf Arctic Shuffle 1 & 2 10 Pin Shuffle GI Joyride Lunarcy Jounce Play Marbles Ion Charge
iDrop Dead. Hardly anyone has played it and they're totally missing out... hopefully the lite will be up soon so you'll all realize how badass it is.
I'll try out the lite (when it comes out) but it does not look appealing at all imho...hopefully the lite could change that
You might want to hold out and check out Finger Physics which is due out soon. There is a thread about it here.
