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
First-person physics platformer about leaping across a convoy of crashing trucks.

Execution · Pure Mechanics
A falling-block puzzle game about fast, precise stacking under increasing speed.
Clustertruck leans Execution (Pure Mechanics); Tetris Evolution leans Execution (Pure Mechanics).
Tetris Evolution leans a little harder on execution, though the gap is small.
Clustertruck
Frame-tight jumps across moving trucks
Tetris Evolution
fast, precise piece placement under speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
No opponent
Tetris Evolution
no opponent modeling in core mode
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
Physics chaos makes truck piles unpredictable
Tetris Evolution
piece sequence randomness
Clustertruck leans a little harder on optimization, though the gap is small.
Clustertruck
Route lines and ability use for speedruns
Tetris Evolution
optimal stacking and clearing strategy
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.
