head to head
Mini Metro asks more than Angry Birds Blast!, and the gap is optimization.

Optimization · Systems & Chaos
A tile-matching puzzle of planning clears against a randomized board.

Optimization · Pure Optimization
Minimalist transit puzzle; route topology under spawning pressure.
Angry Birds Blast! leans Optimization (Systems & Chaos); Mini Metro leans Optimization (Pure Optimization).
Mini Metro leans a little harder on execution, though the gap is small.
Angry Birds Blast!
Tapping tile clusters has no timing demand
Mini Metro
light real-time line-drawing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Blast!
Solo match game, no opponent to model
Mini Metro
no adversary
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Angry Birds Blast!
Board layout and power-up drops are randomized
Mini Metro
station spawn pattern
Mini Metro leans clearly harder on optimization.
Angry Birds Blast!
Planning matches and power-up combos to clear objectives
Mini Metro
line topology and routing
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.
