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

Optimization · Pure Optimization
Tests physics contraption engineering against fixed puzzle levels.

Optimization · Pure Optimization
A surreal puzzle-adventure about nesting worlds inside orbs.
Bad Piggies leans Optimization (Pure Optimization); Cocoon leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
Light steering of contraptions after building
Cocoon
Inputs are simple movement and a button.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
No opponent of any kind
Cocoon
Puzzles are fixed designs.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
Levels are fixed and repeatable
Cocoon
No randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
Contraption engineering for three-star solutions is the game
Cocoon
Pure puzzle logic, solvable by reasoning.
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.
