Tetris EffectvsTetris Worlds
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.
Tetris Effect
Execution · Pure Mechanics
Classic Tetris execution under audiovisual flow, speed still decides everything.
Tetris Worlds
Execution · Pure Mechanics
A Tetris variant testing piece-placement speed with multiple ruleset modes.
Tetris Effect leans Execution (Pure Mechanics); Tetris Worlds leans Execution (Pure Mechanics).
Tetris EffectTetris Worlds
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.
Tetris Effect
Piece placement under speed and Zone timing is the whole test
Tetris Worlds
Fast precise piece placement under speed is the lead
Reads0 vs 1
Tetris Worlds leans a little harder on reads, though the gap is small.
Tetris Effect
Solo experience with no opponent to model
Tetris Worlds
Multiplayer adds light prediction but mostly solo speed
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Tetris Effect
Randomised bag is bounded and quickly mappable
Tetris Worlds
Piece bag is random but bounded and mappable
Optimization4 vs 5
Tetris Worlds leans a little harder on optimization, though the gap is small.
Tetris Effect
Stacking theory and Zone usage have known optimal lines
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.
