Gear Rotation Lab

Gear Rotation Lab is a mechanical puzzle app built around linked gear trains. Players drag driver gears, watch real tooth-count ratios reverse and scale motion, and sync glowing markers across interlocking meshes before the torque budget runs out.


The core experience is Mesh Sync: eighteen labs that introduce idlers, locked anchors, clutch links, ratchet drives, and precision tolerances. Clutch nodes let you disconnect branches, align subsystems, then reconnect the train. Stars reward efficient clears, while Workshop offers a free sandbox for ratio practice without pressure.


Around the labs, Gear Codex explains mesh contact, gear ratios, idlers, clutches, ratchets, and torque planning in concise field notes. Achievements track laboratory milestones, and settings cover hints, snap strength, and haptics. The result is a complete offline gear puzzle suite with a neon mechanical identity and a unique rotation-physics challenge at its center.
