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 reflex test of paddle precision against accelerating ball physics.

Execution · Pure Mechanics
A rhythm racer that turns any music file into a reflex puzzle track.
Arkanoid: Doh It Again leans Execution (Pure Mechanics); Audiosurf 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.
Arkanoid: Doh It Again
Paddle precision under accelerating ball speed is everything
Audiosurf
Lane-switching to the beat tests reaction speed.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Arkanoid: Doh It Again
No opponent - bricks do not adapt
Audiosurf
No opponent.
Arkanoid: Doh It Again leans a little harder on variance, though the gap is small.
Arkanoid: Doh It Again
Power-up drops and ball angles add bounded randomness
Audiosurf
Track generated from song, then fixed.
Audiosurf leans a little harder on optimization, though the gap is small.
Arkanoid: Doh It Again
Brick-clearing order and power-up choices have known answers
Audiosurf
Block-matching color strategy learnable per song.
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.
