head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
A visual programming puzzle that teaches algorithmic thinking through factory-floor instruction sequences.

Optimization · Pure Optimization
A first-person factory builder that is pure logistics optimization.
Human Resource Machine leans Optimization (Pure Optimization); Satisfactory leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Human Resource Machine
Dragging instructions has no timing component
Satisfactory
Light platforming, no real mechanical ceiling.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Human Resource Machine
No opponent; purely computational puzzle
Satisfactory
No adaptive opponent in the world.
Satisfactory leans a little harder on variance, though the gap is small.
Human Resource Machine
Input data is fixed per level with no randomness
Satisfactory
Resource nodes are fixed once mapped.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Human Resource Machine
Writing minimal correct assembly-like programs to pass each input sequence
Satisfactory
Ratios, logistics, and factory layout are everything.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
