Tungsten Heavy

Tungsten Heavy puts you on the bench of an old incandescent bulb factory. Draw steady circles to wind fine tungsten wire onto the mandrel - spin too fast and the wire snaps, too slow and the coil pitch fails. Spot weld the lead pins with perfect timing, pump out the air and seal inert gas, then burn in your bulb and watch it glow.

Take orders for 40W, 60W and 100W bulbs, earn coins by quality, and manage wire stock and machine wear. Upgrade your workshop with a precision mandrel, tension stabilizer, auto welder jig, vacuum pump pro and full machine service.

Simple to learn, hard to master. Craft the perfect filament.
