Find the fleet, sink the fleet

Set five ships out on your own sea chart, then call your shots on the enemy's. A bone peg is a miss, a red peg is a hit, and the whole game is the hunt in between.

Fleet Battle

Fleet Battle is played in a chart room below decks. Two admiralty charts lie side by side on an oiled oak desk: yours, with the fleet drawn on it, and the enemy's, blank cream water from A1 to J10. Drag a carrier, a battleship, a cruiser, a submarine and a destroyer onto your chart, tap one to turn her broadside, or press auto-place and let the quartermaster do it. Then you start calling squares, and every answer goes into the paper — a bone peg where the shell threw up spray, a red peg where it found steel.

The opponent is not a random number generator. The Captain sweeps the water on a parity lattice so no ship can slip between his shots, and the moment he scores a hit he works outwards along the line until the hull is finished. The Admiral has a harder brain again: before every shot he counts, for every square still open, how many ways each of your surviving ships could still be lying across it, and fires at the square that is most likely to be wet steel. Give him a straight line of hits and he will run it to both ends. He needs a little over forty shots to clear a board, so a careless fleet is a short game.

Play a quiet duel against either officer, or hand the device back and forth in the two players mode, where a curtain drops between turns so nobody peeks at the other fleet. Salvo changes the arithmetic completely: you fire one shot for every ship you still have afloat, so the first hull you lose costs you a gun and the last one leaves you plinking away one square at a time. Wins, games played and your current streak are kept in the browser, so the desk remembers how the campaign is going.

Tips for Fleet Battle

Fleet Battle rewards a fleet that is hard to read. Spread your five ships out and vary which way they face, because both officers work along a line the moment they find a hit, and the Admiral counts how many ways each surviving ship could still lie across every open square. Auto-place is quick, but placing by hand lets you avoid an obvious layout.

When you call your own shots, do not pick neighbouring squares at random. Space your early shots so no ship can slip between them, then, once you get a red peg, work outwards along the line until that ship goes down. Bone pegs show where ships cannot be, so use them to rule out water. In Salvo you fire one shot for every ship still afloat, so keeping your fleet afloat matters even more there: each ship you lose costs you a gun. Start against the Captain before taking on the Admiral.

How to play Fleet Battle

In Fleet Battle each side hides a fleet of five ships on a sea chart of ten squares by ten, from A1 to J10, and tries to sink the other fleet first. The fleet is a carrier, a battleship, a cruiser, a submarine and a destroyer. Drag the ships onto your chart, tap one to turn it, or press auto-place; on a keyboard, R turns a ship while you set out the fleet.

Then the two sides take turns to call shots on each other's chart. The enemy chart starts as blank water, and you fire by tapping a square, or by moving the cursor with the arrow keys and pressing Enter or Space. A bone peg marks a miss and a red peg a hit. Once every square of a ship has been hit, that ship goes down, and the side that sinks the whole enemy fleet first wins. A good plan is to spread your early shots across the chart, then work along the line once you find a hit.

On your own you play against one of two officers. The Captain sweeps the water in a pattern so no ship can slip between his shots, and the Admiral works out which open square is most likely to hold a ship. In the two players mode you pass the device back and forth, and a curtain drops between turns. Salvo changes the rules: you fire one shot for every ship you still have afloat. P pauses and M mutes.

About Fleet Battle

Fleet Battle is based on the classic guessing game of hidden fleets, long played with pencil and paper on two squared grids and later as a board game with pegs. Kiloo's version keeps the familiar rules and sets them in a chart room below decks, with two admiralty charts on an oiled oak desk, red and bone pegs, ship silhouettes, splashes and hit flashes.

Fleet Battle is a calm game of logic and deduction, which makes it a good fit for older children learning to plan ahead and for anyone who enjoys a thoughtful duel. The computer opponents give it depth: the Captain is the right place to start, and the Admiral counts how each of your surviving ships could still lie across every open square before he fires, needing a little over forty shots to clear a board. With a friend, the two players mode and its curtain keep each fleet secret on one shared device, and your wins, games played and current streak are kept in the browser.

Frequently asked questions

Is Fleet Battle free to play?

Yes. Fleet Battle is free to play in your browser on Kiloo, with nothing to download and no account to create. Your wins, games played and current streak are kept in the browser you play in.

Can I play Fleet Battle on my phone?

Yes. On a phone or tablet you drag your ships onto your chart and tap a square on the enemy chart to fire. On a computer you use the arrow keys with Enter or Space, and R turns a ship while you set out the fleet.

Can two people play Fleet Battle on one device?

Yes. In the two players mode you hand the device back and forth, and a curtain drops between turns so nobody sees the other fleet. On your own you can play a quiet duel against the Captain or the Admiral.

How does Salvo mode work in Fleet Battle?

In Salvo you fire one shot for every ship you still have afloat. The first ship you lose costs you a shot each turn, and with only one ship left you are down to a single square per turn.

What are the rules of Fleet Battle?

Each side places five ships on a chart of ten squares by ten, then the two take turns to fire at a square on the other chart. A red peg is a hit and a bone peg a miss. Hit every square of every enemy ship before your own fleet goes down and you win.

How do you beat the Admiral in Fleet Battle?

Make your fleet hard to read. Spread the five ships out and vary which way they face, since the Admiral fires at the square most likely to hold a ship and runs a line of hits to both ends. He needs a little over forty shots to clear a board, so make yours count.
