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 vault management sim about optimising dwellers, rooms, and resource loops.

Optimization · Systems & Chaos
Scripted detective work that tests gathering hidden clues and assembling the intended deduction.
Fallout Shelter leans Optimization (Pure Optimization); Sherlock Holmes: The Awakened leans Optimization (Systems & Chaos).
Sherlock Holmes: The Awakened leans a little harder on execution, though the gap is small.
Fallout Shelter
Tapping menus only
Sherlock Holmes: The Awakened
Walking and clicking through scenes, no twitch demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout Shelter
No opponent
Sherlock Holmes: The Awakened
The case is fully scripted, nothing models you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout Shelter
Incident spawns and lunchbox loot rolls
Sherlock Holmes: The Awakened
Clues are hidden information until each scene is searched
Fallout Shelter leans a little harder on optimization, though the gap is small.
Fallout Shelter
Dweller stats and room layout are fully solvable
Sherlock Holmes: The Awakened
Deduction chains have one solvable correct answer
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.
