head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Systems & Chaos
Building an Australian outback town by solving its licence-gated crafting progression and visitor systems.

Optimization · Pure Optimization
Growing a floating base by solving resource chains and research order against scripted ocean threats.
Dinkum leans Optimization (Systems & Chaos); Raft 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.
Dinkum
Hunting and combat have light timing demands
Raft
Shark hook-attacks require minimal timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Dinkum
Animals and NPCs use scripted, predictable behaviour
Raft
Shark and seagull AI are scripted with no player modelling
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dinkum
Resource deposits and visiting merchant stock introduce moderate RNG
Raft
Island loot tables and resource drift introduce randomness
Raft leans a little harder on optimization, though the gap is small.
Dinkum
Town development, licence unlocks, and resource routing are solvable
Raft
Raft expansion, food chains, and research order are solvable systems
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.
