    How to play

    Sink all five ships of the other fleet before it sinks yours. The score counts the ships still afloat in both fleets, yours first.

    The fleets

    Each side has its own sea, 10 × 10, A to J across and 1 to 10 down, and a fleet of five ships: a flagship of 5 squares (it flies the admiral’s pennant), a cruiser of 4, a destroyer and a submarine of 3, and a patrol boat of 2. Ships lie across or down and never touch, not even at a corner.

    Laying out

    Your fleet starts laid out at random, and Shuffle lays it out again. Drag a ship to move it; where it can’t lie, it is ringed in Coral. Tap a ship to turn it about the square you tapped; it shifts along to fit if it can. Ready starts the battle.

    Firing and sinking

    Take turns, one shot each, firing into Their waters, the big sea; Your fleet beside it shows their shots. A hit burns, a miss splashes, and the last shot on each sea is ringed in Amber. A ship hit on every square sinks, shows itself and is struck through in Their fleet; the water around it is dotted and can’t be fired at. Against the computer you fire first; with a friend, who fires first is drawn. At the end, See the seas shows where every ship lay.

    The computer

    Level sets how well it plays (Medium to start), and you can change it at any time; during a battle it is for the next one. Easy fires anywhere, and after a hit, half the time beside it. Medium hunts on a checkerboard, then follows a hit’s line. Hard works out every way the ships still afloat could lie and fires where most of them meet.

    With a friend

    Send a friend the link (Copy link) and play from two browsers. Each of you lays out your own fleet and presses Ready, and the battle starts once both have; until then the other side shows Laying out or Ready. Neither of you ever sees the other’s ships, only where the shots land and the ships sunk. Play again starts a new battle, and Leave the game ends it for both of you.

    Controls

    Tap or click a square in their waters to fire: on your turn a reticle marks the square under the pointer, and its letter and number light up. With a keyboard, ↑ ← ↓ → aim (the square shows over their waters) and Enter or Space fires. While you lay out your fleet, 1 to 5 pick a ship, ↑ ← ↓ → move it, R turns it and Enter is Ready.

    A battle against the computer is kept in this browser from Ready, with its level, and comes back paused; a fleet you are still laying out is not kept. A friend’s battle goes through a small server that keeps both fleets and answers each shot, so neither of you sees the other’s ships; it forgets the battle a day after the last shot, or as soon as one of you leaves.
