Description

This is a holiday spin-off of SimplePhysics. If you like this game, then be sure to check out SimplePhysics, which has over 10 more amazing levels.

Help Santa at the North Pole with some of his projects. He needs help with everything from building his sleigh to designing toys. You will need to make sure your designs are safe though, and they will be tested 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." If you want to impress Santa, 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 playback slider lets you rewind time and play back the simulation in slow motion. Find out why your design failed, or use the slider to replay an awesome explosion in slow motion.
