GearCraft: Mechanical Puzzle

Build machines that really work.

GearCraft is a calm, tactile puzzle game about machines that almost work. Every level is a small mechanism on a workbench: a motor on one side, a dial, a flag, a bell or a clock hand on the other, and a few empty pegs in between. Pick the right gears, press Run, and watch the motion travel through your machine, gear by gear.

When something goes wrong, GearCraft tells you why. Gears that jam, a load that is too heavy, a hand that stops at the wrong hour: every failure is explained, and the part that caused it lights up.

FROM ONE GEAR TO A WATCH MOVEMENT
• Start with a single gear and learn by doing: direction, speed, idlers
• Choose gear sizes to make outputs spin faster, slower or backwards
• Stack parts on shafts across two layers; run belts, chains and drive shafts
• Master ring gears, planetary sets, gearboxes, clutches and differentials
• Wind springs, swing levers, strike bells with cams, program stepper motors
• Take real watch movements apart and put them back together: bridges, jewels, the mainspring and the escapement

159 HANDCRAFTED PUZZLES IN 7 WORLDS
Clockwork, Factory, Automotive, Workshop, Robotics, Grand Machines and Watchmaker. Every level is made by hand and checked by a solver, so every puzzle is fair and has a real solution.

FIND THE PERFECT MACHINE
Any working machine solves a level. Three stars go to the one that uses the fewest parts: the same minimum our solver proved.
