head to head
Neither is simply harder - they are hard in different places. Portal 2 demands more execution; The Case of the Golden Idol demands more variance.

Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.

Optimization · Pure Optimization
A forensic deduction game where each frozen crime scene must be fully solved through logical elimination.
Portal 2 leans Optimization (Pure Optimization); The Case of the Golden Idol leans Optimization (Pure Optimization).
Portal 2 leans clearly harder on execution.
Portal 2
Portal placement requires some precision but timing is lenient.
The Case of the Golden Idol
Drag-and-drop word selection demands no motor skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
No opponent; puzzles are static.
The Case of the Golden Idol
Historical tableau puzzles have one correct solution each
The Case of the Golden Idol leans clearly harder on variance.
Portal 2
Puzzles are deterministic with no randomness.
The Case of the Golden Idol
Hidden names and roles are concealed information to uncover
The Case of the Golden Idol leans a little harder on optimization, though the gap is small.
Portal 2
Solving the puzzle's logic IS the entire game.
The Case of the Golden Idol
Each scene is a closed logic puzzle with exactly one valid solution
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.
