Clockwork Bench
Clockwork Bench is a free 3D gear puzzle. On a wooden bench you drag gears with numbered teeth onto shafts and turn a crank to see which way each part spins. Teeth only mesh when their spacing, layer and tooth gaps agree, so a gear that just overlaps does nothing. Each mesh reverses direction and changes speed by the tooth ratio, and compound shafts multiply it. Odd gear loops jam. Get the fan and the lift moving within the right speed and torque range inside 120 seconds. There are 24 benches that add idler gears, compound shafts, upper-layer gears, heavy loads and clutches that must be engaged in order.
How to play
- Drag a gear from the tray onto a shaft and set it with the seating dial.
- Press RUN and turn the crank slider.
- Make the fan and lift spin at the signed ratios and enough torque.
Tips
- Overlap on screen is not engagement. Check the spacing and layer.
- An idler flips direction without changing the overall ratio.
- Slow the crank and use reduction for heavy loads.
Questions
Is this a tile puzzle?
No. Meshed teeth carry speed and direction, and wrong spacing jams.
How do I score?
You score when each mechanism does its work inside the right speed and torque range.
Is there a daily bench?
Yes, one shared bench a day.
