The server sees the board. Your phone sees your view.
Matches are server-authoritative. Each player’s device receives only what that player has earned the right to see, so no client ever holds the opponent’s fleet.

How the lab built it
A game engine with no hidden state
The rules engine is a pure module with time and randomness injected from outside, so every rule is testable in isolation. It runs under property-based tests with full branch coverage.
Bots without machine learning
The training fleets use classical search: hunt after a hit, parity targeting and probability maps. They cost nothing to run.
Eight languages
German, English, Spanish, French, Indonesian, Portuguese, Russian and Turkish.
Who it’s for
Nauvo is for anyone who wants a quick, fair game against a friend, a stranger or a bot. A match takes about ninety seconds, so it fits a commute or a coffee break, and it works with no account.
