AudiosurfvsSpin Rush
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Audiosurf
Execution · Pure Mechanics
A rhythm racer that turns any music file into a reflex puzzle track.
Spin Rush
Execution · Practiced Mastery
An arcade-style runner/spinning obstacle game.
Audiosurf leans Execution (Pure Mechanics); Spin Rush leans Execution (Practiced Mastery).

Axis by axis
Execution7 vs 6
Audiosurf leans a little harder on execution, though the gap is small.
Audiosurf
Lane-switching to the beat tests reaction speed.
Spin Rush
precise timing of spins and jumps in runs
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
No opponent.
Spin Rush
no adaptive opponent present
Variance2 vs 3
Spin Rush leans a little harder on variance, though the gap is small.
Audiosurf
Track generated from song, then fixed.
Spin Rush
randomized obstacle and track elements
Optimization4 vs 4
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Block-matching color strategy learnable per song.
Spin Rush
route and upgrade optimization across runs
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.
