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.

Optimization · Pure Optimization
A flash puzzle about rolling a rectangular block into the hole without falling off.

Optimization · Pure Optimization
A chaotic comedy adventure whose elaborate multi-step puzzles test patience with absurd causal chains.
Bloxorz leans Optimization (Pure Optimization); Deponia 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.
Bloxorz
Deliberate moves; no time pressure.
Deponia
Point-and-click with no timing elements
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bloxorz
No opponent at all.
Deponia
Comedy adventure with scripted characters throughout
Deponia leans a little harder on variance, though the gap is small.
Bloxorz
Levels are fixed and fully visible.
Deponia
Deterministic puzzle world with fixed solutions
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bloxorz
Each level is a literally solvable move puzzle.
Deponia
Convoluted Rube Goldberg puzzle chains demand careful causal mapping
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.
