head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Optimization · Pure Optimization
A school murder mystery where class trials test players' ability to assemble evidence into the correct counter-argument.

Optimization · Pure Optimization
A hidden-object detective adventure testing fixed-puzzle deduction.
Danganronpa: Trigger Happy Havoc leans Optimization (Pure Optimization); Enigmatis 3: The Shadow of Karkhala leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Danganronpa: Trigger Happy Havoc
Class trial rhythm sections add minor timing layer
Enigmatis 3: The Shadow of Karkhala
Point-and-click needs no motor precision
Enigmatis 3: The Shadow of Karkhala leans a little harder on reads, though the gap is small.
Danganronpa: Trigger Happy Havoc
Blackened is scripted per chapter; no adaptive deduction opponent
Enigmatis 3: The Shadow of Karkhala
Solo detective story; no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Danganronpa: Trigger Happy Havoc
Hidden killer identities and evidence drive trial uncertainty
Enigmatis 3: The Shadow of Karkhala
Hidden objects but fixed per-scene solutions
Danganronpa: Trigger Happy Havoc leans a little harder on optimization, though the gap is small.
Danganronpa: Trigger Happy Havoc
Gathering evidence and building the correct argument chain is a solvable deduction loop
Enigmatis 3: The Shadow of Karkhala
Solving fixed puzzles and clue routing is the loop
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.
