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.

Variance · Pure Chaos
Trial-and-error absurdist gags where guessing the joke is the whole game.

Variance · Pure Chaos
Pachinko-puzzle hybrid where one lucky bounce triggers Ode to Joy.
McPixel leans Variance (Pure Chaos); Peggle leans Variance (Pure Chaos).
Peggle leans a little harder on execution, though the gap is small.
McPixel
One click per gag, no dexterity
Peggle
Aiming the launcher is gentle
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
McPixel
Pure authored absurdity, no adversary
Peggle
No opposition whatsoever
Peggle leans a little harder on variance, though the gap is small.
McPixel
Gag outcomes are deliberately unguessable until tried
Peggle
Bounce physics chaos decides most shots
Peggle leans a little harder on optimization, though the gap is small.
McPixel
Once outcomes are known each scene is trivially solved
Peggle
Angle planning and power choice for setups
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.
