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 3D factory-building puzzle where spatial reasoning and throughput efficiency are the entire challenge.

Optimization · Pure Optimization
A musical adventure where learning and reversing melodic spells forms a closed combinatorial puzzle system.
Infinifactory leans Optimization (Pure Optimization); Loom 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.
Infinifactory
Block placement has no timing pressure
Loom
Musical spell sequences require accurate note input under light pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Infinifactory
No opponent; alien factory puzzle game
Loom
Fantasy narrative with scripted antagonists
Loom leans a little harder on variance, though the gap is small.
Infinifactory
Build targets are fixed and deterministic
Loom
Deterministic world with no randomised elements
Infinifactory leans a little harder on optimization, though the gap is small.
Infinifactory
Engineering 3D factory lines that assemble alien products correctly and efficiently
Loom
Learning and combining distaff spells in the correct order is a fully solvable logic system
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.
