Simply drag, drop, and snap building blocks together into behaviors for your game.

Simple
Get started with Beginner’s Blocks.
3D game development can be overwhelming. That’s why Brain Builder ships with ready-to-use Beginner’s Blocks. For example, they make it this easy to get your character moving and turning:

Powerful
Make complete games within Brain Builder.
The blocks and rules are concise and to the point. This keeps your projects clean and readable. Our compiler ensures that everything executes as fast as hand written code. And with blocks for every low-level Unity 3D function, nothing is out of your reach.
Fast
Build a first prototype in minutes.
We have included a library of Behavior Bundles so that you don’t have to do everything yourself. Just tick a check box to:
- Walk about randomly
- Avoid obstacles
- Drive a car
Get more behaviors for free through Brain Builder updates.
Universal
Sell your games in the App Store and on Android Market.
Brain Builder supports the same platforms that Unity does. Build games on your computer and distribute them on PC, Web, iOS, and Android.

Flexible
Create your own building blocks.
Our Beginner’s Blocks are themselves built from other, more basic, blocks. You can do the same to build your own custom blocks. Rename them as you think fits, or even translate them into your own language.
