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 · Pure Mechanics
Player-made platforming gauntlets where precision execution meets unseen level design.

Execution · Pure Mechanics
The classic execution-under-acceleration test wrapped in an immersive audiovisual experience.
Super Mario Maker leans Execution (Pure Mechanics); Tetris Effect: Connected leans Execution (Pure Mechanics).
Tetris Effect: Connected leans a little harder on execution, though the gap is small.
Super Mario Maker
Community kaizo levels push platforming precision to extremes
Tetris Effect: Connected
Precision placement under acceleration is the entire skill ceiling
Tetris Effect: Connected leans a little harder on reads, though the gap is small.
Super Mario Maker
Levels are static once built; nothing adapts
Tetris Effect: Connected
Zone-battle opponents exist but format leans on execution
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Maker
Unknown user levels are hidden information until attempted
Tetris Effect: Connected
Piece bag is bounded random but quickly mappable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Super Mario Maker
Mastering tool tech and level conventions is learnable
Tetris Effect: Connected
T-spin and stacking strategy is knowable but execution overrides it
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.
