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 chaotic comedy adventure whose elaborate multi-step puzzles test patience with absurd causal chains.

Optimization · Pure Optimization
Methodically decoding intricate fixed mechanisms hidden in a puzzle dollhouse.
Deponia leans Optimization (Pure Optimization); The Room 4: Old Sins 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.
Deponia
Point-and-click with no timing elements
The Room 4: Old Sins
Twisting mechanisms onscreen takes no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deponia
Comedy adventure with scripted characters throughout
The Room 4: Old Sins
A fixed dollhouse of secrets; nothing adapts
The Room 4: Old Sins leans a little harder on variance, though the gap is small.
Deponia
Deterministic puzzle world with fixed solutions
The Room 4: Old Sins
Mechanisms are hidden information until discovered
Deponia leans a little harder on optimization, though the gap is small.
Deponia
Convoluted Rube Goldberg puzzle chains demand careful causal mapping
The Room 4: Old Sins
Each puzzle box is a deterministic mechanism to decode
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.
