Tetris Effect: ConnectedvsThe Callisto Protocol
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Tetris Effect: Connected
Execution · Pure Mechanics
The classic execution-under-acceleration test wrapped in an immersive audiovisual experience.
The Callisto Protocol
Execution · Pure Mechanics
A melee-heavy sci-fi horror game where reactive parry timing and dodge reads dominate over system depth.
Tetris Effect: Connected leans Execution (Pure Mechanics); The Callisto Protocol leans Execution (Pure Mechanics).

Axis by axis
Execution9 vs 8
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
The Callisto Protocol
Melee-parry timing and dodge-direction choices are the core skill
Reads1 vs 1
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
The Callisto Protocol
Mutants follow telegraphed scripted attack patterns
Variance3 vs 3
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Tetris Effect: Connected
Piece bag is bounded random but quickly mappable
The Callisto Protocol
Some loot containers and drop variability add mild uncertainty
Optimization4 vs 5
The Callisto Protocol leans a little harder on optimization, though the gap is small.
Tetris Effect: Connected
T-spin and stacking strategy is knowable but execution overrides it
The Callisto Protocol
Weapon upgrades and credit management have limited depth
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.
