Ladja
Slovenian for ship. Lay your fleet out across the grid — by hand, or let the app scatter it if you are impatient — and then take turns firing into water you cannot see. Every hit narrows the search. Every miss costs a turn. The last square of a ship never gets less satisfying to call.
What makes it last is that nothing is hidden from you except the one thing that matters. There is no luck to blame and no information you were denied: both sides see the same board, know the same fleet, and differ only in how well they read the splashes.
- A computer admiral that actually hunts. It probes, and once it lands a hit it closes in to finish the ship rather than wandering off. Several difficulty levels.
- Or a person. Pass the phone across the table for a hot-seat duel.
- Readable at a glance. Hits bloom, misses ripple, sunk ships are revealed, and your fleet sits beside your shots so the whole battle is on one screen.
- A series, not a single game. A running tally keeps score across the evening.
- Nothing to load. Every part of the board is drawn in the app, which is why it stays crisp and why it works with the handset in flight mode.

Here is the floor of this game: what happens if you give the shooting no thought at all, and simply fire into squares you have not tried yet, in whatever order they come.
That turns out to be exactly computable, and not by simulation. Shots in a random order are a shuffle of the grid, so the question "when does the last ship cell come up?" is an order statistic. For K ship cells among N squares the last of them arrives, on average, on shot K(N + 1) / (K + 1), and the first on shot (N + 1) / (K + 1). Two fractions, no estimates.
Where those two shots fall
Not here: no grid, no fleet, no shot fired and nothing hunted. No parity pattern, no probability map, no advice about where ships like to sit or what to do after a hit. This measures how badly it goes with no thought at all. Everything above that floor is the game, and the game is where it stays.
A game about ships, and nothing more
Ladja is a pen-and-paper parlour game of hidden fleets that has been played for over a century, implemented from scratch. It is not a simulation of any real vessel, navy, conflict or weapon, it depicts nothing that happened, and it is not connected to, endorsed by or derived from any board game, film or franchise on the same theme. The ships are rectangles.
