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
Macabre management sim about running a medieval cemetery as a business.
Denki Blocks! leans Optimization (Pure Optimization); Graveyard Keeper 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
Graveyard Keeper
Light action farming inputs
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
Graveyard Keeper
Villagers run on fixed schedules
Graveyard Keeper leans a little harder on variance, though the gap is small.
Denki Blocks!
Each puzzle is fixed, nothing random to map
Graveyard Keeper
Minor drop randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Denki Blocks!
Solving the block-merging sequence is the entire game
Graveyard Keeper
Sprawling tech trees and grind-route efficiency
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.
