Subway SurfersvsZombie Tsunami
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.
Subway Surfers
Execution · Twitch Chaos
An endless runner testing swipe reflexes against procedurally generated obstacle streams.
Zombie Tsunami
Execution · Twitch Chaos
One-touch reflex timing against procedurally generated obstacle streams.
Subway Surfers leans Execution (Twitch Chaos); Zombie Tsunami leans Execution (Twitch Chaos).
Subway SurfersZombie Tsunami
Axis by axis
Execution6 vs 6
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Subway Surfers
Swipe reaction speed at increasing pace is everything
Zombie Tsunami
One-touch jump timing for a growing horde is the whole test
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Subway Surfers
No opponent - just oncoming obstacles
Zombie Tsunami
No opponent - obstacles are procedural
Variance4 vs 4
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Subway Surfers
Procedural track segments keep each run unseen ahead
Zombie Tsunami
Procedural level generation decides what each run offers
Optimization2 vs 3
Zombie Tsunami leans a little harder on optimization, though the gap is small.
Subway Surfers
Powerup upgrades matter little beyond reflex play
Zombie Tsunami
Upgrade spending is a thin meta layer
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.
