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.

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

Optimization · Systems & Chaos
A time-travel mystery testing deduction of fixed cause-and-effect puzzle chains.
Danganronpa: Trigger Happy Havoc leans Optimization (Pure Optimization); Time Hollow leans Optimization (Systems & Chaos).
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
Time Hollow
Drawing portals with the stylus is trivial
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Danganronpa: Trigger Happy Havoc
Blackened is scripted per chapter; no adaptive deduction opponent
Time Hollow
A fixed mystery plot, no adversary
Time Hollow leans a little harder on variance, though the gap is small.
Danganronpa: Trigger Happy Havoc
Hidden killer identities and evidence drive trial uncertainty
Time Hollow
Story twists are hidden information on first play
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
Time Hollow
Deducing where and when to open portals is fixed-solution puzzling
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.
