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.

Variance · Systems & Chaos
A short first-person horror game testing nerve against scripted home invasion scares.

Variance · Systems & Chaos
A hidden-object search game about spotting items in cluttered themed scenes.
Evil leans Variance (Systems & Chaos); I Spy Spooky Mansion Deluxe leans Variance (Systems & Chaos).
Evil leans a little harder on execution, though the gap is small.
Evil
Walking and looking; minimal physical demand
I Spy Spooky Mansion Deluxe
Clicking found objects, no twitch element
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Evil
Scare events are scripted, not an adaptive mind
I Spy Spooky Mansion Deluxe
No opponent; it is a solo search
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Evil
Hidden scares and events drive the unknown tension
I Spy Spooky Mansion Deluxe
Items are hidden in cluttered scenes to discover
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Evil
Figuring out what to do next is the small loop
I Spy Spooky Mansion Deluxe
Scanning systematically speeds finds, little deeper 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.
