Gearlock 3D is a mechanical logic puzzle. Place gears to build a working drivetrain and get the machine spinning the right way at the right speed to crack open an ancient vault.

Every mesh flips the direction, belts carry it straight, and locked shafts share it. Watch out for fragile gears that crack if over-sped and rusted gears that break the machine. Choose your route, open every latch, and add each vault's treasure to your Great Clock. A cog-and-clockwork brain-teaser that clicks satisfyingly into place.
