The Blender Game Engine is a component of Blender, a free and open-source comprehensive 3D production suite, used for making real-time interactive content. The game engine was written from scratch in C++ as a mostly independent component, and includes support for features such as Python scripting and OpenAL 3D sound.

A table of what typical users can achieve
| Beginner | Intermediate | Advanced |
|---|---|---|
| adding a basic cube | adding a timer | using python console |
| adding a basic material | adding simple textures | using combinations of textures |
| Using logic | using logic with properties | using logic with python |
Features:
- Graphical logic editor for defining interactive behavior without programming
- Collision detection and dynamics simulation now support Bullet Physics Library. Bullet is an open source collision detection and rigid body dynamics library developed for PlayStation 3
- Shape types: Convex polyhedron, box, sphere, cone, cylinder, capsule, compound, and static triangle mesh with auto deactivation mode
- Discrete collision detection for RigidBody simulation
- Support for in-game activation of dynamic constraints
- Full support for vehicle dynamics, including spring reactions, stiffness, damping, tire friction etc.
- Python scripting API for sophisticated control and AI, fully defined advanced game logic
- Support all OpenGLTM lighting modes, including transparencies, Animated and reflection-mapped textures
- Support for multimaterials, multitexture and texture blending modes, per-pixel lighting, dynamic lighting, mapping modes, GLSL vertexPaint texture blending, toon shading, animated materials, support for Normal Maping and Parallax Mapping
- Playback of games and interactive 3D content without compiling or preprocessing
- Audio, using the SDL toolkit
- Multi-layering of Scenes for overlay interfaces
