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 story-first adventure with gentle item-puzzle logic as its only test.

Optimization · Pure Optimization
Evidence-gathering and deduction-board logic with no physical or adversarial layer.
Back to the Future: The Game leans Optimization (Pure Optimization); 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.
Back to the Future: The Game
Telltale point-and-click, zero dexterity
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.

Back to the Future: The Game
Puzzle solutions are hidden 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.
Back to the Future: The Game
Light item-logic puzzles drive each episode
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.
