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
The classic execution-under-acceleration test wrapped in an immersive audiovisual experience.

Execution · Pure Mechanics
A twin-stick bullet-hell dungeon crawler testing dodging and aim.
Tetris Effect: Connected leans Execution (Pure Mechanics); Wildcat Gun Machine leans Execution (Pure Mechanics).
Tetris Effect: Connected leans a little harder on execution, though the gap is small.
Tetris Effect: Connected
Precision placement under acceleration is the entire skill ceiling
Wildcat Gun Machine
Dodging dense bullet patterns and aiming carries every room
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Tetris Effect: Connected
Zone-battle opponents exist but format leans on execution
Wildcat Gun Machine
Enemies are scripted bullet-hell, not adaptive
Wildcat Gun Machine leans a little harder on variance, though the gap is small.
Tetris Effect: Connected
Piece bag is bounded random but quickly mappable
Wildcat Gun Machine
Procedural dungeon layouts and drops add randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Tetris Effect: Connected
T-spin and stacking strategy is knowable but execution overrides it
Wildcat Gun Machine
Weapon and key-card choices reward modest planning
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.
