Battleship · Морской бой · Schiffe versenken
Ten hidden ships. Find them first.
The game as it is played on squared paper: 10 ships in 20 cells, none touching another, and every hit earns another shot. Your browser referees, and a bot fires back.
Against a bot, no account and no download: your browser referees. It works on a phone.
How a game goes
Two grids, two fleets, and one question asked a cell at a time.
Place your fleet
Arrange ten ships in secret — or shuffle — so that no two touch, not even at a corner.
Fire
Pick a cell in the bot's waters. The answer comes at once: miss, hit, or sunk.
Hit, and fire again
A hit or a sinking keeps your turn; a miss hands it over. Sink the whole fleet first to win.
The referee keeps the paper
What is certain is crossed out for you
Ships never touch, so the corners of a hit and the border of a sunk ship can only be water. On paper you cross them out yourself; here the referee does, and a shot at them is refused rather than wasted.
4 levels
A bot for every player
Each level searches differently, and each beats the one below it. Every bot sees only what its own shots have told it.
- 1
Beginner
Fires at random, and leaves a hit ship to chance: about 66 shots to sink a fleet.
- 2
Casual
Fires at random and finishes every ship it hits: about 58.5 shots.
- 3
Steady
Searches along a diagonal stripe the longest ship must cross: about 56.6 shots.
- 4
Sharp
Counts every way the ships afloat could lie, and fires where most of them cross: about 55.1 shots.
90%
of games won by the sharp bot against the beginner.
Measured over 1,000 games with the same fleets and the first shot swapped, and over 2,000 fleets for the shots a level needs.
What you get
One game or a match
Matches of 1, 3, 5 games. Whoever lost the last game fires first in the next.
A bot that cannot peek
The bot is handed only its own view of the game, and its fleet is drawn so that sinking a few ships tells you nothing about the rest.
Made for a phone
The table fills the screen, upright or sideways, and every cell is a button.
In three languages
English, Russian and German, with the letters of each: A to J, or А to К.
