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

Execution · Practiced Mastery
Rapid capsule placement against a clock, with planning for chains under random pill draws.

Execution · Practiced Mastery
A marble-shooter testing aim and timing to match advancing colored spheres.
Dr. Mario leans Execution (Practiced Mastery); Luxor 3 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.
Dr. Mario
Fast capsule placement under rising speed decides clears
Luxor 3
Aiming and timing shots at moving spheres is the core
Dr. Mario leans a little harder on reads, though the gap is small.
Dr. Mario
Versus mode exists but garbage exchange rewards speed, not prediction
Luxor 3
Solo - no opponent to predict
Luxor 3 leans a little harder on variance, though the gap is small.
Dr. Mario
Random pill colors against fixed virus layouts, quickly bounded
Luxor 3
Sphere color sequences add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Dr. Mario
Chain setups and virus-clearing order follow known patterns
Luxor 3
Power-up usage and chain planning improve scores
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.
