MillipedevsTetris Effect
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.
Millipede
Execution · Pure Mechanics
Raw arcade reflexes against accelerating swarms with mild spawn randomness.
Tetris Effect
Execution · Pure Mechanics
Classic Tetris execution under audiovisual flow, speed still decides everything.
Millipede leans Execution (Pure Mechanics); Tetris Effect leans Execution (Pure Mechanics).
MillipedeTetris Effect
Axis by axis
Execution8 vs 8
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Millipede
Trackball precision under swarming pressure is everything
Tetris Effect
Piece placement under speed and Zone timing is the whole test
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Millipede
Enemies follow fixed movement rules
Tetris Effect
Solo experience with no opponent to model
Variance3 vs 2
Millipede leans a little harder on variance, though the gap is small.
Millipede
Spawn waves and DDT timing vary run to run
Tetris Effect
Randomised bag is bounded and quickly mappable
Optimization3 vs 4
Tetris Effect leans a little harder on optimization, though the gap is small.
Millipede
Mushroom-field management is a thin strategic layer
Tetris Effect
Stacking theory and Zone usage have known optimal lines
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.
