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 · Practiced Mastery
A casual game about finding and shooting hidden toy ducks across a map.

Optimization · Pure Optimization
Sci-fi thriller played as the station AI solving its own crisis.
Find 100 Ducks and Blast Them! leans Optimization (Practiced Mastery); Observation leans Optimization (Pure Optimization).
Find 100 Ducks and Blast Them! leans a little harder on execution, though the gap is small.
Find 100 Ducks and Blast Them!
Casual aiming, low precision demand
Observation
Camera control and interface manipulation
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Find 100 Ducks and Blast Them!
Static toy ducks don't adapt
Observation
Events are fully authored
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Find 100 Ducks and Blast Them!
Duck placement hidden until searched
Observation
Mystery unknown until uncovered
Observation leans a little harder on optimization, though the gap is small.
Find 100 Ducks and Blast Them!
Searching the fixed map systematically is the only depth
Observation
Systems puzzles and station schematics solving
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.
