head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
A sliding-block puzzle about deducing the right merge sequence per board.

Optimization · Pure Optimization
A city builder where mastering land value, budgets, and infrastructure math grows the metropolis.
Denki Blocks! leans Optimization (Pure Optimization); SimCity 3000 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.
Denki Blocks!
Sliding blocks has no timing or twitch demand
SimCity 3000
Point-and-click planning; pause anytime.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Denki Blocks!
Solo puzzle with no opponent to predict
SimCity 3000
No adversary exists.
SimCity 3000 leans a little harder on variance, though the gap is small.
Denki Blocks!
Each puzzle is fixed, nothing random to map
SimCity 3000
Random disasters and neighbor deal timing.
SimCity 3000 leans a little harder on optimization, though the gap is small.
Denki Blocks!
Solving the block-merging sequence is the entire game
SimCity 3000
Land value, utilities, and ordinance math reward pure system mastery.
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.
