head to head
Fallout: New Vegas asks more than Denki Blocks!, and the gap is execution.

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

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Denki Blocks! leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Denki Blocks!
Sliding blocks has no timing or twitch demand
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Denki Blocks!
Solo puzzle with no opponent to predict
Fallout: New Vegas
Scripted factions and enemies
Fallout: New Vegas leans a little harder on variance, though the gap is small.
Denki Blocks!
Each puzzle is fixed, nothing random to map
Fallout: New Vegas
Some loot and crit RNG
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
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
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.
