What is a Geneva drive?

A Geneva drive converts continuous rotation into intermittent motion. A driver crank with a pin meshes with a star wheel (slotted wheel), advancing it by one step per revolution. It is used in mechanical watches, film projectors, and indexing tables.

How do you play Geneva Drive?

Rotate the driver crank using the control buttons. Each click advances the connected star wheel by one position. Wheels linked by chains rotate together. Position all star wheels at their target angles to win.

What are chains in this puzzle?

Chains couple star wheels together so they advance together. When you rotate a chain, all wheels in that chain advance by one step. Some chains include counter-rotating wheels that step in opposite directions.
