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.

Optimization · Systems & Chaos
A gentle perception test of systematically scanning a scene for hidden frogs.

Optimization · Pure Optimization
Telltale's episodic comedy adventure sending Guybrush Threepwood after a pox plaguing the Caribbean.
100 Hidden Frogs leans Optimization (Systems & Chaos); Tales of Monkey Island leans Optimization (Pure Optimization).
100 Hidden Frogs leans a little harder on execution, though the gap is small.
100 Hidden Frogs
Clicking frogs takes no dexterity
Tales of Monkey Island
Click-driven; no physical demands.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
100 Hidden Frogs
No opponent exists
Tales of Monkey Island
LeChuck and pirates are pure script.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
100 Hidden Frogs
Frog locations are unknown until found, then fixed
Tales of Monkey Island
Modern design telegraphs most puzzle information.
Tales of Monkey Island leans a little harder on optimization, though the gap is small.
100 Hidden Frogs
Systematic visual scanning is the only lever
Tales of Monkey Island
Episodic inventory puzzles each have one intended 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.
