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.

Execution · Pure Mechanics
A swipe-em-up arcade game where slicing accuracy against random fruit spawns is the whole skill.

Execution · Pure Mechanics
NES Zapper classic testing raw aim against pop-up gangster targets.
Fruit Ninja leans Execution (Pure Mechanics); Hogan's Alley leans Execution (Pure Mechanics).
Hogan's Alley leans a little harder on execution, though the gap is small.
Fruit Ninja
Swipe accuracy and combo timing
Hogan's Alley
Pure light-gun aim and reaction speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fruit Ninja
No opponent
Hogan's Alley
Cardboard targets cannot adapt
Fruit Ninja leans a little harder on variance, though the gap is small.
Fruit Ninja
Random fruit and bomb spawns
Hogan's Alley
Target order randomizes within simple sets
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fruit Ninja
Combo and crit systems are shallow but real
Hogan's Alley
Little to plan beyond gangster-vs-civilian recognition
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.
