SimplePhysics lets you design complex structures for everything from tree houses to ferris wheels and then simulates your design with a sophisticated physics engine.

A wise person once said: "An engineer is someone who can do for a dime what any fool can do for a dollar." In SimplePhysics, your design must not only be strong enough, it must be cheap enough to win.

Create your design in seconds with the blueprints editor. If you make a mistake, simply tap the Undo button. Zoom in and out by pinching the screen and pan the view using a two finger drag.

While testing, you can see how the strain is distributed across your design. Areas that are under immense strain are colored bright red, while other areas are colored green. This allows you to find and fix problem areas in your design.

The finger test lets you use your finger to push and pull on your design. You can use this with pinpoint accuracy, or you can just smash your design to smithereens. The finger test has an explosive new twist. You can now create explosions by tapping the screen for ultimate annihilation.

The newly added Bomb Shack level includes a dummy with full support for ragdoll physics. Throw him around, blow him up, and smash him against your design.

The slow motion feature lets you slow things down so you can see how your design is failing, and it is also incredibly fun to watch explosions destroying your design in slow motion.

Terrific engineering fun!

Got my 6 year old hooked — that’s worth the price of admission right there!

This includes 12 different building challenges with increasing difficulty. Learn how to transfer stress, distribute loads, and handle jerks (yes, the technical term for change in acceleration over time).

Once you come up with a solution, try to build it under budget!

Love this game. Like others I want for more. That said, there is a rich amount of play in the trimming to absolute minimum required to pass the tests. Requires a bit of tenacity/obsession to unlock that aspect of the game.

Well worth the money, IMO.

Great game, challenging puzzles

I’ve played this game since the initial release. My daughter plays it quite a bit now, too. Always trying to beat my scores. The leaderboards seem to be gone, now, though.

Would love to see more levels added (even if it was a paid add-on)!

It’s very good. Only problem with it is that there are not enough levels
