head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Practiced Mastery
Falling-block stacking under speed pressure with a twist of directional randomness.

Execution · Practiced Mastery
A pinball-platformer hybrid where flippers fling a mail-delivering beetle across an open island.
Pac-Attack leans Execution (Practiced Mastery); Yoku's Island Express leans Execution (Practiced Mastery).
Pac-Attack leans a little harder on execution, though the gap is small.
Pac-Attack
Placing pieces under rising speed and gravity decides survival
Yoku's Island Express
Pinball flipper timing drives all traversal
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pac-Attack
Solo stacking - no opponent modelling
Yoku's Island Express
Solo, nothing models you
Pac-Attack leans a little harder on variance, though the gap is small.
Pac-Attack
Pac-Man's random direction choice adds placement uncertainty
Yoku's Island Express
Ball physics adds small bounce unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Pac-Attack
Stack shapes that feed Pac-Man efficiently are learnable patterns
Yoku's Island Express
Learning table layouts and exploration routes
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.
