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
Hand-drawn puzzle where overlapping illustrated panels unlock impossible connections.

Optimization · Pure Optimization
Mobile production-chain and layout optimisation paced by timers.
Gorogoa leans Optimization (Pure Optimization); SimCity BuildIt 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.
Gorogoa
Dragging panels requires no skill
SimCity BuildIt
Tapping menus has no skill floor
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
No opponent exists
SimCity BuildIt
No adversary; trade is asynchronous
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
Solutions unknown on first encounter only
SimCity BuildIt
Market prices and material drops add mild randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
Each panel arrangement has one elegant solvable answer
SimCity BuildIt
Production chains, layout and currency timing are the whole game
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.
