head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A reflex test of paddle precision against accelerating ball physics.

Execution · Pure Mechanics
Motion-controlled WarioWare where you snap the remote into poses to clear five-second microgames.
Arkanoid: Doh It Again leans Execution (Pure Mechanics); WarioWare: Smooth Moves 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
WarioWare: Smooth Moves
Instant motion-pose changes and gesture accuracy under pressure
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
WarioWare: Smooth Moves
No adaptive opposition, just scripted prompts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Arkanoid: Doh It Again
Power-up drops and ball angles add bounded randomness
WarioWare: Smooth Moves
Random microgame draws keep each run unpredictable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Arkanoid: Doh It Again
Brick-clearing order and power-up choices have known answers
WarioWare: Smooth Moves
Learning every form and microgame solution converges
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.
