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.

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

Execution · Pure Mechanics
The sequel to the marble-chain shooter, adding bosses and frog-hopping lily pads.
Pokémon Pinball leans Execution (Twitch Chaos); Zuma's Revenge! leans Execution (Pure Mechanics).
Zuma's Revenge! leans a little harder on execution, though the gap is small.
Pokémon Pinball
Flipper timing and nudge control are the whole input
Zuma's Revenge!
Quick aiming with hop and slide mechanics added
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
Zuma's Revenge!
Bosses are scripted patterns
Pokémon Pinball leans a little harder on variance, though the gap is small.
Pokémon Pinball
Ball physics and catch-mode rolls add real randomness
Zuma's Revenge!
Random ball colours feed the chain
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
Zuma's Revenge!
Combo chaining and power-up timing
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.
