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.

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

Optimization · Pure Optimization
A minimalist side-scrolling strategy where a mounted monarch drops coins to build walls against nightly greed raids.
Angry Birds Blast! leans Optimization (Systems & Chaos); Kingdom: New Lands leans Optimization (Pure Optimization).
Kingdom: New Lands leans a little harder on execution, though the gap is small.
Angry Birds Blast!
Tapping tile clusters has no timing demand
Kingdom: New Lands
Just riding and coin-dropping under time pressure
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
Kingdom: New Lands
Greed waves follow deterministic escalation
Angry Birds Blast! leans a little harder on variance, though the gap is small.
Angry Birds Blast!
Board layout and power-up drops are randomized
Kingdom: New Lands
Island layouts and vendor spawns randomise
Kingdom: New Lands leans a little harder on optimization, though the gap is small.
Angry Birds Blast!
Planning matches and power-up combos to clear objectives
Kingdom: New Lands
Expansion order and economy timing decide survival
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.
