Features

Everything you love about the classic.
Nothing you don't.

Familiar rules, with the polish and depth of a modern game.

💥

Ships that go down with a bang

Every sinking triggers a fiery 3D explosion with debris, shockwaves and smoke, then the wreck burns on the water.

🎯

Sonar ripples

Every miss pings across the water so you always know where you've looked.

How to play

Learn it in a minute.
Master it in a lifetime.

Two hidden oceans, one winner. A typical battle takes about five minutes.

Place your fleet

Drag five ships onto your 10×10 grid, rotate them, or hit Randomise. Ships can't overlap.

Take aim

On your turn, click a square on the enemy grid. Columns run A to J, rows 1 to 10.

Read the water

A ripple is a miss. Flames mean you've hit a ship. Hit every square to sink it.

Sink them all

Turns alternate. The first captain to destroy the whole enemy fleet wins.

Pro tips

Think like an admiral.

Small habits that win games.

Hunt in a checkerboardEvery ship is at least two squares long, so firing every other square finds them faster.
Finish what you startAfter a hit, fire at the neighbouring squares until the ship goes down.
Avoid obvious spotsDon't line your ships up along the edges. Experienced players check there first.
Use the heat mapOn Windows, press H to see where ships are most likely to be hiding.
Count the gapsA gap of two squares can only hold a destroyer, so don't waste shots on it.
Watch your statsAccuracy, streaks and sunk ships are tracked live in the battle bar.
