## What is Dummy Defense?

The spin-off of SimplePhysics. Protect your dummy from explosions, boulders, spiked walls, and more!

Use the blueprints editor to design a structure that will protect your dummy, Melvin, from some random danger. You'll have to work with the available materials. Most of the time you'll use wood, sometimes you'll use concrete, but you must always use your most important asset: your brain.

A wise person once said: "An engineer is someone who can do for a dime what any fool can do for a dollar." In Dummy Defense, your design must not only be strong enough, it must be cheap enough to win. Building cheaper structures will earn you more stars on a level.

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 slow motion slider 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.

### 5/5 — Great engineering game!

*2025-04-02, version 1.4.3*

It is a fun, iterative game that helps you understand how to best support or protect a dummy (or yourself) through the simplest building materials.

This is a must for any budding civil engineer you would know, starting from childhood!

### 1/5 — Broken game?

*2024-06-18, version 1.4.3*

I played this game years ago and i loved it, sadly on my new ipad I can’t seem to get past the main menu. Please fix!

### 5/5 — Great game

*2022-12-13, version 1.4.3*

This is a great game and is challenging which is what I like. The only improvement is to have sound effects for breaking and obstacles ect. Overall brilliant game I can’t stop playing it

### 5/5 — Really great game

Please....

### 4/5 — This game is a lot of fun. One small, minor thing though.

*2021-04-28, version 1.4.3*

I love this game. It is one of my favorites. It is very challenging, but who doesn’t like a good challenge. It isn’t even a bad price. And the add-on is another 99 cents, but still. It is a fun game. The ONLY thing I wish could be fixed is screen rotation. The screen wont rotate. It stays one way, but I hardly can stand it being upside down. It bothers me though. Probably not everyone. Other than that this game is great.

### 5/5 — Nice
