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

Optimization · Pure Optimization
Cozy space exploration and base-building sandbox.

Optimization · Pure Optimization
A physics-contraption puzzle about engineering Rube Goldberg machines.
Astroneer leans Optimization (Pure Optimization); Crazy Machines 3 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.
Astroneer
Light terrain tool inputs
Crazy Machines 3
Placing parts has no twitch component
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Astroneer
No adaptive opponents
Crazy Machines 3
Solo puzzle - no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Astroneer
Planet resource distribution
Crazy Machines 3
Physics deterministic but chains feel lightly chaotic
Crazy Machines 3 leans a little harder on optimization, though the gap is small.
Astroneer
Base layout, power chains, automation
Crazy Machines 3
Engineering a working contraption is the whole game
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.
