What the developers have to say:

Why Early Access?

“GearBlocks is now at a stage where the fundamentals are there, it has plenty of content, and there’s lots to do in the game. It makes sense to get it into the hands of the Community so that players can put it all to the test, provide feedback, and impact the future direction of the project.”

Approximately how long will this game be in Early Access?

“This is difficult to say exactly, it depends somewhat on the Community feedback, requesting additional features, content, and so on. I’m aiming for the game to be in Early Access for roughly 12 months.”

How is the full version planned to differ from the Early Access version?

“This will likely be a combination of:-
  • Additional content (more parts, maps, scenarios etc.)
  • Refinements of existing features (e.g. improved building tools, performance optimisation).
  • Additional features (such as aerodynamics).

I have a huge list of things I’d love to add to the game, but none of this is set in stone, it will be shaped by input from the Community.”

What is the current state of the Early Access version?

“The demo version has a cut down selection of parts, maps, tools, and game modes, but it will give you a good sense of current the state of the game. It still has a few bugs here and there but is stable and has been extensively tested by the GearBlocks Community.

The Early Access version has the full selection of hundreds of parts, all the available tools, modding support, more maps, and a damage system.”

Will the game be priced differently during and after Early Access?

“The price may increase during or after Early Access if and when it makes sense, depending on the features I add and so on.”

How are you planning on involving the Community in your development process?

“While I have definite ideas about where I’d like to take this game, I want the project to be guided by input from you guys, the GearBlocks Community! Player feedback from the demo has already been invaluable, and it would be fantastic for this to continue.”

About This Game

GearBlocks is an open ended sandbox game for mechanically minded builders.

You can build a car with rack and pinion steering and a working drive-train with a differential gear. Or you could make a run-and-jump parkour course with motorised bouncy platforms, or an unstoppable walking mechanical elephant. The only limit is your imagination...and physics.


Build or repair your creations anywhere on the map. Snap parts together, resize them, change their materials, paint them, and link their behaviours together. Choose from over 200 parts, including functional mechanical elements such as motors, gears, pulleys, joints, springs, actuators, and much more.


Turn, grab and shove your machines and watch the parts physically interact. Jump into the driver's seat and put your vehicles through their paces. Crash and smash your constructions to smithereens.


Learn how to build with the in-game tutorial scenario. Explore the example constructions to see how they’re put together. Test your builds in the included challenge scenarios.


Make rag-dolls from body parts and use them as your custom player character. Mod the game with Lua scripting to create your own custom tools, scenarios, challenges and mini-games.


Share your creations with the community, try out what others have made, and maybe learn a new building trick or two along the way!
