AudiosurfvsTetris Effect
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.
Tetris Effect
Execution · Pure Mechanics
Classic Tetris execution under audiovisual flow, speed still decides everything.
Audiosurf leans Execution (Pure Mechanics); Tetris Effect leans Execution (Pure Mechanics).

Axis by axis
Execution7 vs 8
Tetris Effect leans a little harder on execution, though the gap is small.
Audiosurf
Lane-switching to the beat tests reaction speed.
Tetris Effect
Piece placement under speed and Zone timing 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.
Audiosurf
No opponent.
Tetris Effect
Solo experience with no opponent to model
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Audiosurf
Track generated from song, then fixed.
Tetris Effect
Randomised bag is bounded and quickly mappable
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.
Tetris Effect
Stacking theory and Zone usage have known optimal lines
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.
