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

Optimization · Pure Optimization
Solving procedurally generated corporate heists through precise resource and power management under escalating alarms.

Engineer a pandemic; evolution order is the puzzle.
Invisible, Inc. leans Optimization (Pure Optimization); Plague Inc: Evolved leans Optimization (Pure Optimization).
Invisible, Inc. leans a little harder on execution, though the gap is small.
Invisible, Inc.
Turn-based movement; no twitch demands whatsoever
Plague Inc: Evolved
no reflex
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Invisible, Inc.
Corporate guards patrol on scripted timers; no adaptive opponent
Plague Inc: Evolved
world response scripted
Invisible, Inc. leans a little harder on variance, though the gap is small.
Invisible, Inc.
Procedural floor layouts and alarm escalation add significant run variance
Plague Inc: Evolved
country event timing
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Invisible, Inc.
Power allocation, agent pairing, and escape routing are the core puzzle
Plague Inc: Evolved
evolution order heavily solved
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.
