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.

Variance · Light / Casual
A hidden-object game about finding cats in hand-drawn cityscapes.

Optimization · Light / Casual
A classic point-and-click adventure where solving inventory puzzles is the entire challenge.
100 Hidden Cats leans Variance (Light / Casual); Grim Fandango Remastered leans Optimization (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
100 Hidden Cats
Clicking cats has no timing demand
Grim Fandango Remastered
no physical skill ceiling, point-and-click
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
100 Hidden Cats
Solo - nothing to predict
Grim Fandango Remastered
no opponents, puzzle-driven
100 Hidden Cats leans a little harder on variance, though the gap is small.
100 Hidden Cats
Cat positions unknown until scanned
Grim Fandango Remastered
no meaningful randomness
Grim Fandango Remastered leans a little harder on optimization, though the gap is small.
100 Hidden Cats
Systematic searching trivially completes it
Grim Fandango Remastered
item and dialogue puzzle logic solvable
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.
