head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
Tetris extended into 3D - spatial packing optimization executed under accelerating pressure.

Execution · Practiced Mastery
Neon top-down massacre where each floor is a one-mistake execution puzzle.
Blockout leans Execution (Practiced Mastery); Hotline Miami leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Blockout
Rotating polycubes on three axes under time pressure strains hands
Hotline Miami
One-hit-death rooms demand flawless fast inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Blockout
Solo pit - nothing to predict
Hotline Miami
Enemies are dumb scripted reactors
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Blockout
Piece sequence is random but quickly bounded
Hotline Miami
Slight enemy behavior wobble between restarts
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Blockout
3D packing has optimal layer-clearing patterns to internalise
Hotline Miami
Route planning and mask choice per floor
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.
