head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, 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 first-person endless runner testing reflexes on a doomed spaceship.
Fruit Ninja leans Execution (Pure Mechanics); Infinity Runner leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Fruit Ninja
Swipe accuracy and combo timing
Infinity Runner
Fast reflexes for dodging and QTEs define play
Infinity Runner leans a little harder on reads, though the gap is small.
Fruit Ninja
No opponent
Infinity Runner
Scripted obstacles, no adaptive opponent
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
Infinity Runner
Some procedural obstacle variation
Infinity Runner leans a little harder on optimization, though the gap is small.
Fruit Ninja
Combo and crit systems are shallow but real
Infinity Runner
Little to solve beyond reaction memorization
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.
