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.

Execution · Pure Mechanics
A cute endless runner starring a dog dodging traffic.

Execution · Practiced Mastery
An open-world crime game where combat combos and driving skill carry the action.
Puppy Cross leans Execution (Pure Mechanics); Sleeping Dogs leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Puppy Cross
Simple lane-dodging reflex timing
Sleeping Dogs
brawling and driving need timing/aim
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Puppy Cross
No opponents present
Sleeping Dogs
scripted enemy AI, no adaptation
Puppy Cross leans a little harder on variance, though the gap is small.
Puppy Cross
Obstacle spawn randomness varies runs
Sleeping Dogs
minor loot and traffic randomness
Sleeping Dogs leans a little harder on optimization, though the gap is small.
Puppy Cross
Minimal systems, casual endless runner
Sleeping Dogs
upgrade paths and mission routes solvable
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.
