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
Short free sokoban puzzler about assembling a harem of sharply dressed demon girls.

Optimization · Pure Optimization
A life simulator where planning schedules and needs against a solvable system is the real game.
Helltaker leans Optimization (Pure Optimization); The Sims 4 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.
Helltaker
One bullet-dodge finale aside, no dexterity
The Sims 4
no physical skill ceiling at all
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Helltaker
No opponent
The Sims 4
no opponents, simulated NPCs only
The Sims 4 leans a little harder on variance, though the gap is small.
Helltaker
Fully deterministic puzzles
The Sims 4
minor random events and needs decay
Helltaker leans a little harder on optimization, though the gap is small.
Helltaker
Each sokoban level has an exact move solution
The Sims 4
life and career system optimization dominant
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.
