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
The second Deponia chapter continues elaborate fixed-solution puzzle chains demanding methodical thinking.

Optimization · Pure Optimization
A long parade of self-contained logic puzzles wrapped in a mystery story.
Chaos on Deponia leans Optimization (Pure Optimization); Professor Layton and the Diabolical Box leans Optimization (Pure Optimization).
Chaos on Deponia leans a little harder on execution, though the gap is small.
Chaos on Deponia
Same interface as original; zero reflex component
Professor Layton and the Diabolical Box
Stylus taps - zero dexterity demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Chaos on Deponia
Continuation of scripted comedy narrative
Professor Layton and the Diabolical Box
No opponent; a parade of standalone brainteasers
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Chaos on Deponia
Deterministic solutions throughout second chapter
Professor Layton and the Diabolical Box
Puzzles are fixed; only their first encounter surprises
Chaos on Deponia leans a little harder on optimization, though the gap is small.
Chaos on Deponia
Increasingly complex puzzle architecture rewards systematic inventory management
Professor Layton and the Diabolical Box
Each brainteaser has one clean logical solution to find
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.
