Instructions and settings

Your orders

Each captain commands a Carrier (5), Battleship (4), Cruiser (3), Submarine (3), and Destroyer (2) on a 10 × 10 grid.

  • Place ships horizontally or vertically, without overlapping or leaving the board. Ships may touch.
  • Choose a ship and a starting cell, or auto-place the whole fleet. Confirm to start.
  • You fire first. Turns alternate after every shot, including hits. Sink all five enemy ships to win.
  • Unknown water is blank. A dot (•) is a miss, a cross (×) is a hit, and a dark cross (✕) marks a sunk ship. A solid square (■) marks your ship or a revealed enemy ship.
  • Tap or click cells. With a keyboard, Tab into a board, navigate with arrow keys, and press Enter or Space. During deployment, R rotates your selected ship.

Difficulty modes

Easy — occasional follow-up
Mostly fires at random untried cells, and only sometimes checks around a hit.
Normal — follow up on hits
Checks neighbouring cells after a hit. Otherwise, it searches randomly.
Hard — tactical targeting
Follows lines of confirmed hits and favours the most likely remaining ship positions.

All three modes use previous shots only; none can see your hidden ships. During battle, green ship badges mean Afloat and red badges mean Sunk.

Settings

Mission

Changes apply now during deployment, or to your next mission once battle begins. Easy mostly fires at random; Normal follows up on hits; Hard uses tactical targeting. No difficulty can see hidden ships.

Look & motion

Nautical: navy, brass and a ship’s log. Stealth: the original battleship grey. Changes straight away; gameplay is the same in both.

A subtle, slow sweep behind the game. Uncheck to pause. Your device’s reduced-motion setting also keeps it still.

Sound & vibration

On by default: splashes for misses, explosions for hits, a bigger blast when a ship sinks, victory bells and a defeat horn. Audio starts after you interact with the game. Uncheck to mute; theme music stays off unless enabled.

35%

Off by default. An original, looping nautical melody synthesized onboard. Pauses when this tab is hidden. Independent of sound effects.

25%

Optional two-pulse feedback on supported devices. Off by default; disabled for reduced motion.
