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
A lighthearted shooting-gallery game about reflexively gunning down randomly appearing chickens.
Fruit Ninja leans Execution (Pure Mechanics); Moorhuhn 2: Die Jagd Geht Weiter leans Execution (Pure Mechanics).
Fruit Ninja leans a little harder on execution, though the gap is small.
Fruit Ninja
Swipe accuracy and combo timing
Moorhuhn 2: Die Jagd Geht Weiter
precise aiming and shooting reflexes
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
Moorhuhn 2: Die Jagd Geht Weiter
no opponent, solo shooting gallery
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fruit Ninja
Random fruit and bomb spawns
Moorhuhn 2: Die Jagd Geht Weiter
chicken spawn pattern randomness
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
Moorhuhn 2: Die Jagd Geht Weiter
minimal, mostly reflexive scoring
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.
