How to play
2 to 10 players. Sink the other fleets: the last fleet afloat wins.
1. Place your fleet
Put every ship of your fleet on your own sea, across or down. Two ships may touch but never share a square. Nobody sees your fleet. You have 3 minutes: a fleet that is not ready by then is placed at random.
The usual fleet: an aircraft carrier (5 squares), a battleship (4), a destroyer (3), a submarine (3) and a patrol boat (2). The game's creator may choose another fleet and another sea size.
2. Fire, everybody at the same time
Each round, every player fires a few shots (3 by default), each one at a square of the opponent of their choice. When everybody has fired, or when the round's time is up, all the shots land together.
- Every shot is public: everybody sees where it landed, in the water or on a ship.
- A ship hit on every one of its squares sinks, and everybody sees it.
- A player who does not fire in time simply loses those shots.
3. The end
A player whose ships are all sunk is out. The last fleet afloat wins. If the last fleets sink in the same round, it is a draw between them.
