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.

Variance · Systems & Chaos
A hidden-object hunt that tests visual search until every cat location is known.

Variance · Systems & Chaos
Map-and-compass navigation through hidden dangers on a hostile mountain.
A Building Full of Cats leans Variance (Systems & Chaos); Kholat leans Variance (Systems & Chaos).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
A Building Full of Cats
Clicking spotted cats takes no dexterity
Kholat
Walking the mountain takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
A Building Full of Cats
No opponent of any kind
Kholat
The presence stalks on randomised triggers, not a mind
A Building Full of Cats leans a little harder on variance, though the gap is small.
A Building Full of Cats
Hidden cat locations are the entire challenge until found
Kholat
Navigating by map coordinates with hidden danger zones
Kholat leans a little harder on optimization, though the gap is small.
A Building Full of Cats
Systematic screen-scanning is the only strategy layer
Kholat
Landmark navigation and route memory converge with repetition
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.
