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

Execution · Pure Mechanics
A Tetris variant testing piece-placement speed with multiple ruleset modes.
Dr. Mario leans Execution (Practiced Mastery); Tetris Worlds leans Execution (Pure Mechanics).
Tetris Worlds leans a little harder on execution, though the gap is small.
Dr. Mario
Fast capsule placement under rising speed decides clears
Tetris Worlds
Fast precise piece placement under speed is the lead
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dr. Mario
Versus mode exists but garbage exchange rewards speed, not prediction
Tetris Worlds
Multiplayer adds light prediction but mostly solo speed
Dr. Mario leans a little harder on variance, though the gap is small.
Dr. Mario
Random pill colors against fixed virus layouts, quickly bounded
Tetris Worlds
Piece bag is random but bounded and mappable
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
Tetris Worlds
Stacking strategies have known optimal patterns
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.
