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. Features * Realistic physics simulation * Ragdoll physics * Slow motion mode * Stress display shows problem areas in your design * Wide variety of levels! * Finger Test - smash your design to pieces, or blow it up with realistic explosions! * Save/Load designs * E-mail your blueprints to your friends * Universal support for the iPad

+++ Over 50 million players worldwide +++  +++ Number 1 in the games charts for iPad & iPhone in 89 countries +++ +++ SlopeMania add-on with 24 brand new levels, sloping roads and an explosive tank truck +++ +++ Trains add-on with 18 new, beautiful levels and two trains as vehicles +++ In Bridge Constructor you have to prove yourself as an accomplished master bridge builder. Play 40 different levels, and build bridges over deep valleys, canals, and rivers. Stress tests reveal whether the bridge you build can withstand the daily stress of continual use from cars, trucks and, more recently, super-heavy tank trucks. You can choose from a range of materials for each individual bridge, such as wood, steel, cables, or concrete pillars. Use the appropriate materials and stay within budget to build the perfect bridge. The choice of different materials means that there are numerous solutions and approaches and you can build each bridge in any number of ways – your budget is the only limit. The refined grid system allows you to realise your idea of the perfect bridge with even more precision. Let your imagination and creativity run free! And if you happen to run into a dead end, you can pick up valuable tips from the brand new help system! Awesome Add-Ons: SlopeMania & Trains In the SlopeMania add-on you find yourself on the Tiltin Islands, home to three brand new islands where you'll even be building your bridges inside colorful grottoes! The 24 tricky, never-before-seen levels will have you using sloping lanes to overcome the massive height differences. The "Crazy Levels" are the real brainteasers and require out-of-the-box thinking and unusual solutions. Purchase the Trains add-on and get the Choonited Kingdom island group, with a total of 18 new levels across three islands. Build massive bridges that can withstand the enormous weight of the two new vehicles on offer – a commuter train and a heavily loaded freight train. The idyllic and beautifully designed landscapes will make the heart of every railroad fanatic skip a beat. "Trains" and "SlopeMania" are now available at an affordable price as an in-app purchase!
