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 · Systems & Chaos
A noir detective adventure starring Discworld's first private investigator on a case that turns lycanthropic.

Optimization · Pure Optimization
Evidence-gathering and deduction-board logic with no physical or adversarial layer.
Discworld Noir leans Optimization (Systems & Chaos); The Testament of Sherlock Holmes 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.
Discworld Noir
Click-based sleuthing; nothing physical.
The Testament of Sherlock Holmes
Pointing and clicking through crime scenes
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Discworld Noir
Suspects recite fixed noir scripts.
The Testament of Sherlock Holmes

Discworld Noir leans a little harder on variance, though the gap is small.
Discworld Noir
Clue-notebook mystery hides connections until found.
The Testament of Sherlock Holmes
Clues are hidden information until uncovered
The Testament of Sherlock Holmes leans a little harder on optimization, though the gap is small.
Discworld Noir
Cross-referencing clues converges to one fixed solution.
The Testament of Sherlock Holmes
The deduction board is a solvable logic puzzle
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.
