The Incredible Machine

The Incredible Machine video game series( https://en.wikipedia.org/wiki/The_Incredible_Machine_(series) )

is a constructor genre pioneer:

the game puzzles involve creating Rube Goldberg-like

contraptions by adding correct components to the system and activating it to perform some action.

A free form editor with gravity/pressure sliders allows

to create variety of scenarios.

The games provide a limited set of items that can be combined to achieve more complex behavior, with

combinations("contraptions") having a satisfying aesthetic quality of complex 'chain-reaction' processes.
