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 · Twitch Chaos
Flipper execution and table knowledge with Pokémon-catching RNG on top.

Execution · Practiced Mastery
Zuma-style marble shooting testing aim under pressure against a random color feed.
Pokémon Pinball leans Execution (Twitch Chaos); Sparkle 2 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.
Pokémon Pinball
Flipper timing and nudge control are the whole input
Sparkle 2
Accurate orb shots under advancing-chain pressure decide levels
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Pinball
A pinball table has no mind
Sparkle 2
No opponent - the chain just advances
Pokémon Pinball leans a little harder on variance, though the gap is small.
Pokémon Pinball
Ball physics and catch-mode rolls add real randomness
Sparkle 2
Orb color feed is random within bounds
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Pokémon Pinball
Mode routing and table knowledge raise scores predictably
Sparkle 2
Enchantment loadouts and chain-combo planning add a solvable layer
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.
