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.

Execution · Twitch Chaos
A timed perception test of finding hidden objects in cluttered crime scenes.

Optimization · Practiced Mastery
Solving fixed grab-hand puzzles between scripted chase scares.
Criminal Case leans Execution (Twitch Chaos); Poppy Playtime leans Optimization (Practiced Mastery).
Criminal Case leans a little harder on execution, though the gap is small.
Criminal Case
Spotting objects quickly under a timer is the whole test
Poppy Playtime
GrabPack puzzles and chase sequences ask light dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Criminal Case
No opponent; suspects are static puzzle pieces
Poppy Playtime
Toys follow scripted chase triggers, not minds
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Criminal Case
Object placements are unknown per scene until memorised
Poppy Playtime
First-time scares rely on unknown scripted events
Poppy Playtime leans a little harder on optimization, though the gap is small.
Criminal Case
Scene layouts converge to memorised positions on replays
Poppy Playtime
Circuit puzzles have single fixed solutions
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.
