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

The archetypal idle game where optimal purchase order is the entire skill.

Optimization · Pure Optimization
An austere puzzle labyrinth where every room presents a closed logical system that must be fully solved.
Cookie Clicker leans Optimization (Pure Optimization); Lorelei and the Laser Eyes leans Optimization (Pure Optimization).
Lorelei and the Laser Eyes leans a little harder on execution, though the gap is small.

Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.

No opponent
Lorelei and the Laser Eyes
Surreal manor setting has no adaptive opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Golden cookie timing randomness
Lorelei and the Laser Eyes
Some hidden room states and obscured clues require discovery
Lorelei and the Laser Eyes leans a little harder on optimization, though the gap is small.

Purchase order and ascension math are the game
Lorelei and the Laser Eyes
Every puzzle is a precisely designed closed logic problem with exactly one valid solution
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.
