Three routes from the bridge.
Play the live build, trace what changed, or study the testing methods used to keep each difficulty fair and distinct.
Latest field test.
Average computer shots needed to sink a random fleet in the latest simulation. Lower means a sharper opponent.
What changed
The Normal opponent now reshuffles its search order on every new game. The resulting difficulty ladder still holds, and the shuffled order tested about 6% sharper than the old fixed parity order.
Project archive.
The playable build, release history, and design research live on one shelf. Future versions and notes can join the same index without changing the route in.
Release slot 04 will appear here when there is a new build or project note worth keeping.
