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
A wordless robot puzzle adventure where every environmental obstacle has exactly one elegant solution.

Optimization · Pure Optimization
Time-travel mystery wrapped around another batch of self-contained logic puzzles.
Machinarium leans Optimization (Pure Optimization); Professor Layton and the Unwound Future leans Optimization (Pure Optimization).
Machinarium leans a little harder on execution, though the gap is small.
Machinarium
A handful of mini-games require basic timing and clicking precision
Professor Layton and the Unwound Future
Touchscreen inputs carry no mechanical demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Machinarium
Solo robot puzzle game with no opponent
Professor Layton and the Unwound Future
Story antagonists never adapt to the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Machinarium
Arcade mini-games add minor randomness but are skipable
Professor Layton and the Unwound Future
Unknown puzzle answers, fully fixed once deduced
Machinarium leans a little harder on optimization, though the gap is small.
Machinarium
Environmental logic puzzles are tightly designed closed-world problems
Professor Layton and the Unwound Future
Logic puzzles are pure solvable reasoning
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.
