head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Calm path-routing logic puzzles that are pure constraint satisfaction.
AdVenture Capitalist leans Optimization (Pure Optimization); Lyne leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.

Clicking is decorative
Lyne
Tracing paths has no time pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
AdVenture Capitalist
No opponent exists
Lyne
Pure solo logic - no opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
AdVenture Capitalist
All numbers visible and deterministic
Lyne
Every board is fully visible and deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Pure spreadsheet of upgrade timing and resets
Lyne
Each board is a solvable path-routing constraint puzzle
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.
