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
Reflex swipe timing through procedurally assembled obstacle runs.
Fruit Ninja leans Execution (Pure Mechanics); Lara Croft: Relic Run leans Execution (Pure Mechanics).
Fruit Ninja leans a little harder on execution, though the gap is small.
Fruit Ninja
Swipe accuracy and combo timing
Lara Croft: Relic Run
Swipe-timed dodges at increasing speed are the core test
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
Lara Croft: Relic Run
No opponent; obstacles never adapt
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
Lara Croft: Relic Run
Procedural track segments are unknown until they appear
Lara Croft: Relic Run leans a little harder on optimization, though the gap is small.
Fruit Ninja
Combo and crit systems are shallow but real
Lara Croft: Relic Run
Upgrade and power-up choices nudge run length
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.
