Buy GearBlocks PC

Build intricate machines in this indie simulation sandbox. Snap together over 200 parts like motors, gears, pulleys, joints, springs, and actuators to craft cars with rack-and-pinion steering and differentials, parkour courses with motorized platforms, or walking mechanical elephants. Resize, paint, and link parts anywhere on the map while physics governs their interactions. Grab, turn, and drive your creations, then crash them to test durability. Tutorials, example builds, and challenge scenarios help refine skills, alongside rag-doll customization and Lua modding for tools or mini-games. Share designs with the community to discover fresh techniques. Mechanically minded builders thrive on endless open-ended invention.

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.

Create

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.

Interact

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.

Improve

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.

Customise

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.
