Hide your fleet, hunt theirs. Play a friend online with challenges, a rating and match history, take on a sharp hunt-and-target computer, or pass-and-play on one device.
Your ship layout never touches the server during the game — only a locked cryptographic fingerprint does. Both fleets are revealed and every shot re-checked at the end.
A hunt-and-target bot: checkerboard search with a probability map, then it locks on and finishes a wounded ship. Entirely in your browser.
One device, no sign-in. A hand-off screen between turns keeps each fleet secret from the other player.
Carrier, Battleship, Cruiser, Submarine, Destroyer on a 10×10 grid. One shot per turn, no bonus shot on a hit.
