Block Builder FX

Block Builder FX is a physics-based block building game with two modes: Creative and Build Challenges.

Creative Mode: Use your inventory of blocks (and your imagination!) to build anything you want! Then, the real fun begins when you apply physics effects to your build to see how it holds up! Various effects can produce stunning, even beautiful displays of patterns and movement!

Build Challenges Mode: Earn new blocks and other special items by completing build challenges. Build challenges also help you improve your building skills.

Creative Mode Highlights:
- Push the limits of physics with tall towers or wide builds with hundreds of blocks
- Build roller ball courses
- Save your builds
- Share your builds with other Block Builder FX players (export and import builds via the clipboard)
- Lock objects to prevent movement while building
- Enable slow motion with the tap of a button (great for watching falling towers & explosions)
- Apply these stunning physics effects: Random Disappearance, Jolt, Weightlessness, Don't Touch the Ground, Explosion, Go Home, Expand, Cluster, Vortex, Come to Me, Spinners, Throw Ball, Throw Destruction Ball, Throw Explosion Ball, Reverse Gravity, Gravity Push, Gravity Pull
- Add Starter Builds with the touch of a button. Starter Builds can give you inspiration for your own build ideas and demo how some special blocks work
- Use Action Blocks to build ball courses. Action Blocks react in special ways when a ball touches them. Actions blocks include: Explosion Block, Spring Block, Destroyer Block, Power Block, Lock Block, Ball Drop Trigger Block, Wood Ball Dropper Block, Metal Ball Dropper Block, Glass Ball Dropper Block, Teleport Source Block, Teleport Target Block, Accelerator Block, Switch Block, and Switch Trigger Block
