head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Twitch Chaos
An endless runner testing swipe reflexes against procedurally generated obstacle streams.

Execution · Pure Mechanics
An endless runner testing quick reflexes against procedurally generated obstacles.
Subway Surfers leans Execution (Twitch Chaos); Turbo Pug DX 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.
Subway Surfers
Swipe reaction speed at increasing pace is everything
Turbo Pug DX
reflex timing for jumps and dodges
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
Turbo Pug DX
no opponent, endless runner obstacles
Subway Surfers leans a little harder on variance, though the gap is small.
Subway Surfers
Procedural track segments keep each run unseen ahead
Turbo Pug DX
procedurally generated obstacle patterns
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Subway Surfers
Powerup upgrades matter little beyond reflex play
Turbo Pug DX
minimal systems beyond survival 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.
