What is a slider-crank mechanism?

A slider-crank converts rotary motion to linear motion. A rotating crank (circle) connects via a rod to a slider that moves back and forth. The slider position depends on the crank angle, crank radius, and rod length.

How do you play Crankshaft Linkage?

Rotate crankshafts using the control buttons. Each crank drives a slider through a connecting rod. Cranks connected by timing belts rotate together. Position all sliders inside their green target zones to win.

What are timing belts in this puzzle?

Timing belts couple cranks together so they rotate as one unit. When you rotate a coupled group, all cranks in that group turn together. This creates constraints that make puzzles harder.
