grid where you place commands to direct two "waldos"—a red one and a blue one.

Detect specific atoms to create branching paths or logic gates.

Connects or disconnects atoms sitting on bonding plates.

These are the mechanical arms that move through the grid to pick up, rotate, and drop atoms. Key Commands: Grab/Drop: Picks up or releases an atom.

These involve multiple reactors connected by "pipelines." You must manage the timing and flow between reactors to prevent stalls.

SpaceChem tasks you with building "reactors" to transform raw chemical inputs into specific outputs using automation. Reactors are mapped on a
