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 · Pure Mechanics
A rhythm racer that turns any music file into a reflex puzzle track.

Execution · Practiced Mastery
Sustained block-placement speed synced to a sweeping musical timeline.
Audiosurf leans Execution (Pure Mechanics); Lumines Electronic Symphony leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Lane-switching to the beat tests reaction speed.
Lumines Electronic Symphony
Placing blocks against the timeline sweep demands sustained speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
No opponent.
Lumines Electronic Symphony
Solo - no opponent to predict
Lumines Electronic Symphony leans a little harder on variance, though the gap is small.
Audiosurf
Track generated from song, then fixed.
Lumines Electronic Symphony
Random block sequences shape each run moderately
Lumines Electronic Symphony leans a little harder on optimization, though the gap is small.
Audiosurf
Block-matching color strategy learnable per song.

Square-chaining setups and skin-speed strategy reward study
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.
